Throwing ‘something of a light’ from Ningbo China on the functional uses of lighters world wide….

March 2nd – Ningbo Ouqi Smoking Set Co Ltd was founded in 1992. It is a private enterprise specialising in the design, research, development and manufacture of various use lighter and wheel lighter products as well as  additional items such as spot guns, spray guns and straight blanking machines. The Ningbo Ouqi Company is also now a member of IMD online.

Due to its continuous innovation and development, the company now holds numerous key certifications –  ISO900; The 2008 Quality Management System Standard; An “Export Product Quality Permit” ; The BSCI qualification; The “ISO9994” quality inspection and identification and also the highly identifiable, Chinese Enterprise Trademark –  “WANSFA”.

The Company’s impressive manufacturing centre covers an area of 40,000 square meters and there is an on-site personnel rota of more than 800 people. Since its inception, this now fast expanding and developing company, adheres in all respects to a precise operating business commitment  – “quality first, safety first, and continuity – to meet customer expectation.” The Ouqi Smoking Set experts highlight below key marketing aspects reference the  humble lighter today….. 

1. Pragmatism – Nowadays, living standards continue to improve. From the perspective of practicability and environmental protection, people have left matches and bought lighters. There are 1.88 billion smokers in the world. For such a large group, the demand for lighters is huge. As a practical advertising medium, the role of lighters is self-evident.

2. The collection  – Today’s lighters are not only practical, but also developed into a unique handicraft, which has a high appreciation and collection value. There are more and more people collecting lighters now. It is said that there are about 2,000 people in China who collect the lighter.

3. Gifts – The cost of a lighter is not high, it is a good gift for the smoker? 

4. Advertising – Nowadays, lighters have gradually evolved into a new type of advertising media, and savvy manufacturers are willing to adopt them, especially for tobacco and alcohol products.It is also an ideal promotional companion because of its low investment and long-lasting effects. The target group is clear, companies such as beverage companies, hotels, restaurants and more ….. but unfortunately there are not many choices when it comes to lighter manufacturers of excellence.

5. Environmental protection – (as compared with matches). Matches will consume a lot of firewood and destroy the forest. The lighter made of metal shell is very environmentally friendly. Because the metal shell takes a long time and can be recycled. Plastic lighters have a short life cycle, but the plastic case can also be recycled.

The one… two.. three of electric motor design and key parts… from Shengzhou Tianyi …..

The Company principle of hi-tech development and quality technology is at the core of its statement of  business performance – “advance steadily, in refinement”….. here below the Company experts present some valuable basic information on key parts areas of their highly successful motor products….

Electric motor designs can vary quite a lot, though in general they have three main parts: a rotor, a stator and a commutator. These three parts use the attractive and repulsive forces of electromagnetism, causing the motor to spin continually as long as it receives a steady flow of electric current.

Basic Principles

Motors work through the principles of electromagnetism. If you run electricity through a wire, it creates a magnetic field. If you coil the wire around a rod and run electricity through the wire, it creates a magnetic field around the rod.

One end of the rod will have a north magnetic pole and the other will have a south pole. Opposite poles attract one another, like poles repel. When you surround that rod with other magnets, the rod will rotate from the attractive and repulsive forces.

The Stator

Every electric motor has two essential parts: one stationary, and one that rotates. The stationary part is the stator. Though configurations vary, the stator is most often a permanent magnet or row of magnets lining the edge of the motor casing, which is usually a round plastic drum.

The Rotor

Inserted into the stator is the rotor, usually consisting of copper wire wound into a coil around an axle. When electric current flows through the coil, the resulting magnetic field pushes against the field created by the stator, and makes the axle spin.

The Commutator: Basics

An electric motor has another important component, the commutator, which sits at one end of the coil. It is a metal ring divided into two halves. It reverses the electrical current in the coil each time the coil rotates half a turn. The commutator periodically reverses the current between the rotor and the external circuit, or the battery. This ensures that the ends of coils do not move in opposite directions, and ensures that the axle spins in one direction.

More Commutator: Magnetic Poles

The commutator is necessary because the spinning rotor gets its motion from magnetic attraction and repulsion between the rotor and the stator. To understand this, imagine the motor turning in slow motion. When the rotor rotates to the point where the south pole of the rotor magnet meets the north pole of the stator, the attraction between the two poles will halt the spin in its tracks. 

To keep the rotor spinning, the commutator reverses the magnet’s polarity, so the rotor’s south pole becomes the north. The north pole of the rotor and the north pole of the stator then repel each other, forcing the rotor to continue to spin.Washing Machine AC Motor manufacture

Brushes and Terminals

At one end of the motor are the brushes and the terminals. They are at the opposite end from where the rotor exits the motor casing. The brushes send electrical current to the commutator and are typically made of graphite. The terminals are the locations where the battery attaches to the motor and sends the current to spin the rotor.

The business  is also a special local government R&D centre for oxygen barrier (keep food fresh) plastic products like the take out food container – below the Company blog offer their considered expertise and comment  on the worldwide often quite controversial issues linked to many types of ‘take out’ food containers …

Irregular production and non conformity – When you buy takeout or some snacks, you will inevitably use disposable lunch boxes. The original purpose of the use of disposable lunch boxes is to carry food, and to achieve cleanliness and hygiene. However, driven by the interests of some unhealthy manufacturers, they use irregular production processes and adopt some original products that do not conform to the production label. 

Neglecting the quality – Material production results in uneven quality of disposable tableware products in the current market, and in daily life, many business users often neglect the quality of disposable tableware boxes. In many restaurants and snack bars nowadays, there are many kinds of disposable lunch boxes, such as foam, paper, transparent plastic, all kinds of products. There are many unqualified products. How can we judge the quality of disposable tableware and know how to distinguish it? To hurt.

Look, hear, ask ..and look again – There are four ways to distinguish disposable lunch boxes:: that is, look at the appearance and surface of the lunch boxes. Many inferior lunch boxes can be distinguished from the appearance, whether paper or plastic. For plastic type lunch boxes, the surface of good lunch boxes is very smooth, and the transparency is very high, and there are no impurities on the average. The overall shape seems to be very harmonious, and poor-quality lunch boxes, in order to save costs, often use poor-quality materials, transparency is not high, and looks impurities, the overall shape is easy to change, easy to deform.

Smell – Odour is a great feature of inferior lunch boxes, which undoubtedly gives us a good distinguishing condition. Good lunch boxes are tasteless or light, while some inferior lunch boxes emit a great odor because of materials. Even if they are taken out and used for a long time, they will still exist here. It tastes good.

Questions – Right here some necessary questions for dealers when purchasing disposable tableware. Firstly, we should confirm whether the lunch box is manufactured by a regular manufacturer. Secondly, we should confirm that the product has QS certification. Secondly, we should confirm the production standard of the product. Knowledgeable friends can ask about the raw materials used in the production.

Feeling – Touch your hands, feel the feel of the hand, smoothness, hardness, good lunch boxes in smoothness and hardness is very good, and poor quality lunch boxes, you can feel the smoothness is very poor, and hardness is not enough, fine feeling can also feel a sense of granularity.

Nantong Plastic – a ‘hot’ performer in the plastics ‘biz’ …here with key info on the ‘ins and outs’ of plastic production temperature control …..

February 29th – Taizhou Huangyan Nantong Plastic Co Ltd is a professional production and processing company manufacturing household plastic products, baby products, medical supply items and more. It has a complete and scientific quality management system within the company, in order to build the integrity, strength and product quality of  the Taizhou Huangyan Nantong Plastic business, which is very much recognised and appreciated within the industry.

The company’s product range in the main includes – homeware, household and kitchen utensils and flexible storage products. Through its years of operation and development, the Taizhou Huangyan Nantong Plastic business has achieved a reputation for its product quality, cost effectiveness, impressive visual impact and also, for its highly pleasing  and attractive ‘usage experience’.

temperature control

Here below on its readable blog, Nantong Plastic – a new member this week of IMD online – highlights the importance of the control of temperature in the processing of certain of its products, particularly plastic bottles.

Non-flowing temperature: High temperature at which no flow occurs under a certain pressure. A certain amount of plastic is added to the barrel at the upper end of the capillary rheometer die and heated to a certain temperature. After the constant temperature is known to be 10MIN, a constant pressure of 50MPA is applied. If the material does not flow out of the die, it is difficult to increase the temperature of the material by 10 degrees after depressurising, and then apply a constant pressure of the same size after holding 10MIN. 

Viscous flow state 

This continues until the melt flows out of the die, and this temperature is reduced. 10 degrees is the non-flowing temperature of the material. Flowing temperature TF: refers to the temperature at which the amorphous polymer changes from a highly elastic state to a viscous flow state. It is the lower limit of the processing temperature of amorphous plastics.

Decomposition temperature TD: This refers to a polymer in a viscous flow state. When the temperature is further increased, the degradation of the molecular chain will be intensified, and the temperature reached when the polymer molecular chain is significantly degraded is the decomposition temperature. Melting temperature TM: For crystallisation – Type polymer refers to the temperature at which the three-dimensional remote ordered state of the macromolecular chain structure changes to disordered viscous fluid state, also known as the melting point. It is the lower limit of the processing temperature of the crystalline polymer. 

Glass transition temperature TG:  This relates to the amorphous polymer. The transition temperature from the glass state to the high elastic state or from the former to the former. It is the low temperature of the free movement of the macromolecular segment of the amorphous polymer, and it is also the upper limit of the working temperature of the product.

PMI foam company Cashem ‘cashes in’ on the multi-use of its product in all kinds of industries…

Cashem Advanced Materials Hi-tech Co Ltd was established in 2010, and now becomes the first company to specialise in manufacturing PMI foam in China. Backed by the technology of the Institute of Chemistry and The Chinese Academy of Science(ICCAS), Cashem – our latest IMD online member  – has an established highly-qualified R&D team, formed to focus on the industrialisation and serialisation study of the PMI foam product.

widely used

Cashem products are very widely used in leading industries such as Aerospace, Radar, Railways, Shipping and Aviation  Check our their blogging information below on how Cashem foam is also used in numerous more general ‘daily life’ type industries, including Sports Equipment; Medical Apparatus; Unmanned Aerial Vehicles – the drone …and indeed Wind-power…

Sports Equipmen

Composites made of carbon/glass fiber and foam cores have become the new choice for the sports equipment. The rigid and strong PMI foam is an ideal material for lightweight products because it can provide the high specific strength. The capacity of obtaining complex geometry shapes by thermoforming or CNC also make it to achieve the mass production.

Under the heat and pressure, durable composites parts, which have extremely low weight but high strength, can be obtained by the PMI foam and fiber with different kinds of resins. These composites are perfectly suited for sports equipments such as bicycle wheels, skis, rackets and surfboards. It is helpful for the athlete to challenge the limits of human beings.

Medical Apparatus

X-ray and CT scans are used in the clinical diagnosis to inspect the body, in order to obtain the high definition images, increasing the dose of radiation is adapted, but the exposure to radiation has big risk of developing cancer or other diseases.

PMI foam owns lower aluminium equivalent, it means it can get sharper image under smaller dose of radiation, X-ray and CT scans tables, which use PMI as the sandwich structure foam core, dramatically reduces the radiation exposure in diagnostic procedures. Besides the protection for patients against the radiation, high specific strength of PMI foam makes the medical beds conveniently handled by the operator.  

Unmanned Aerial Vehicles 

An unmanned aerial vehicle (UAV), commonly known as a drone, is an aircraft without a human pilot aboard. The flight of UAVs may operate with various degrees of autonomy: either under remote control by a human operator or autonomously by onboard computers.

UAV originated mostly in military applications, their use is rapidly expanding to commercial, scientific, recreational, agricultural, and other applications, such as policing, peacekeeping, and surveillance, product deliveries, aerial photography, agriculture, smuggling, and drone racing. The challenge right now is how to extend its flying range, composites with PMI foam as the sandwich structural core can dramatically reduce the weight of the UAV and offer excellent mechanical properties.


Current, Onshore blades have the lengths up to 60 meters, and the length of offshore blade can even reach to 100 meters. The increase length undoubtedly will increase the loads of the blade, which place higher structural demand for the other components. So the weight reduction of the blade is becoming more and more important.

Comparing to other foam core, PMI can provide the same mechanical properties with low density, which can reduce the weight of the composites components sharply, and because of its fine cell size, resin uptake is also less.

Suxun elevators are right ‘at home’ in homes …and in many other different building environments too!

It is a highly successful,  high-tech enterprise engaged in the design, manufacture, sale, installation and maintenance of numerous elevator and escalator products

This business is dedicated to achieving excellence in  both service and concise management methods, which, in turn, aid development of the Suxun expertise and the accompanying, innovative production of its quality elevators and influential control systems..

The company has obtained a national double A-class certification for  manufacturing, installation, renovation and maintenance of all types and styles of elevators. It has invested extensively in its fully-equipped, impressive production HQ, which has an annual production capacity output of 10,000 units.

Suxun, – our latest IMD Online member from China – has a varied current product range, which includes numerous passenger elevators and also various special use elevators and moving ‘walkways’. Below, Suxun highlight on their blog certain key issues of choice and performance of various  key elevator types…..those that are used in homes!

Home Elevators 

If a customer needs to select a home elevator, there needs ideally to be a clear and simple understanding of the type and use of the elevator, its limitations and indeed its operating abilities. In general, of course, the home elevator is mostly installed in private residential properties as it needs to be the kind of elevator that can simply be used by anybody…..

The speed of a home elevator should generally not exceed 0.4m/s, and it’s speed without the ‘car’ door should not exceed 0.3m/s.  The stroke of the car should not exceed 12m, and the rated load should not exceed 400KG. Generally, household elevators are basically three types – traction elevators, screw elevators, and hydraulic elevators.

Hydraulic elevators…… These are a relatively common type of household elevator. These are widely used in both North America and Europe. However, the hydraulic elevator, can have certain shortcomings such as oil, leakage, environmental pollution, and excessive operating noise. These shortcomings are generally not acceptable in today’s modern building environments and thus the hydraulic machine is not in very extensive demand these days and sales of the product are generally falling.

Traction elevators ….These elevators have the advantage of being space saving. They are also environmentally friendly in terms of their usage. The traction elevators do sell well right now and they will probably continue to do so in the future. Demand for such elevators in the immediate timeline seems relatively certain.  

Screw elevators ….Key to the operating structure of this type of this lift is the ‘nut screw’ which drives it.  It has the advantage of overall structural safety and fastening. No ‘bottom’ pit is needed and there is a self-contained shaft. For sure, these lifts generally offer good space inside. It is also a common elevator choice where there is a range of widely different and quite particular building environments.

‘Bearing down’ on the wear and tear of product failure …and why it might occur!

always informed 

The  company maintains its competitive pricing on its bearing products backed by the business’ responsive, always informed customer service. This latest IMD member company blogs below on aspects of common bearing failure and mechanisms for high temperature bearings….

early rotation failure

In the use of bearings, problems are often encountered, that is, the bearings are qualified after testing, but the bearings are stuck after installation or the early rotation failure during use fails. The main manifestations are the stagnation of rotation, severe peeling of the working surface, severe wear of the cage and even distortion and fracture.

Analysis of failure results shows that there are not many quality problems that belong to the bearings themselves, most of which are caused by improper installation and use. For this reason, high-temperature bearings make a superficial review of common bearing failure modes and mechanisms, in order to play a role of attracting a lot of attention. Bearing failure mechanisms:

Contact fatigue failure …..refers to the failure of the bearing working surface under the effect of alternating stress. Contact fatigue spalling occurs on the bearing working surface, which is often accompanied by fatigue cracks. It first occurs from the large alternating shear stress below the contact surface, and then expands to the surface to form different spalling shapes, such as pitting or pitting. Exfoliation into small pieces is called shallow exfoliation. Due to the gradual expansion of the exfoliation surface, it often expands to the deep layer, forming a deep exfoliation. Deep spalling is the fatigue source of contact fatigue failure.

Wear failure…… refers to the failure caused by the continuous wear of the metal on the working surface caused by the relative sliding friction between the surfaces. Continued wear and tear will cause gradual damage to the bearing parts, eventually leading to loss of bearing dimensional accuracy and other related problems. The wear may affect the shape change, the increase of the fit clearance and the change of the topography of the working surface, which may affect the lubricant or make it contaminated to a certain extent and cause the complete loss of the lubricating function, thus causing the bearing to lose its rotational accuracy and even fail to operate normally. Wear failure is one of the common failure modes of various types of bearings. 

Abrasive wear…..refers to the wear caused by the intrusion of hard particles or hard foreign objects or abrasive debris on the surface of the bearing between the working surfaces of the bearing and the relative movement of the contact surface, often causing furrow-like abrasions on the working surface of the bearing. Hard particles or foreign objects may come from the host or from other adjacent parts of the host system and are fed into the bearing by the lubricant. 

According to the form of wear, it can be divided into common abrasive wear and adhesive wear.

Adhesive wear…. refers to uneven friction on the friction surface due to micro-protrusions or foreign objects on the friction surface. When the lubrication conditions are seriously deteriorated, local friction generates heat due to local friction, which can easily cause local deformation of the friction surface and friction micro-welding. When the surface metal is partially melted, the force on the contact surface will tear the local friction welding point from the substrate and increase plastic deformation. This cycle of adhesion-tearing-adhesion constitutes adhesive wear. Generally speaking, slight adhesive wear is called abrasion, and severe adhesive wear is called bite.

Fracture failure…. The main reason for bearing failure is the two major factors of defect and overload. When the applied load exceeds the strength limit of the material and the part breaks, it is called overload fracture. The main reason for overload is sudden host failure or improper installation. Defects such as micro-cracks, shrinkage holes, air bubbles, large foreign objects, overheated tissues, and local burns of bearing parts can also cause fractures at the defects during shock overload or severe vibration. It should be noted that during the manufacturing process of the bearing, the original inspection of raw materials, forging and heat treatment quality control, and process control can be used to correctly analyse the existence of the above defects through instruments. In the future, control must be strengthened. But in general, the most common bearing fracture failures are overload failures.

Nuances of power and insulation facts, requirement and issues from THE thriving small-motor experts ‘in the know’…..

Shengzhou Liming Motor Co. Ltd is located in “Motor Township”- Shengzhou Economic Development Zone, Zhejiang Province, China. The company – a recent IMD online member – researches, develops and markets a range of highly effective small motors for multiple use.


The business has a small motor product range of 36 series and more than 460 varieties of quality effective motors all well-designed ad set for widely different uses. High-quality materials and unique technology have propelled  this business firmly to the forefront of the small motor production industry.  All its products have passed the CCC certification of China Quality Certification as well as the important European CE certification.


The Shengzhou Liming Motor Co. Ltd  has an experienced R & D team and a strong technical force, which enables the company  to produce and develop exceptional customised motors for very specific customer demand. In recent years, the business introduced to its works range of additional equipment in order to enhance the range and quality of its ever increasing, in-demand, small motor products.  

advanced testing 

Every process in production is backed by advanced testing by the company’s  technical experts. Here below these technical experts at the business explain and highlight guidance on two key small-motor issues – the difference between the rated and actual power and those key insulation elements pertaining to the business’ range of motors … 

Rated and Actual Power  – understanding the difference 

The difference between the rated power and the actual power of the motor means that the motor is in the best working condition under this data. The rated voltage is fixed and the allowable deviation is 10%. The actual power and actual current vary with the size of the load being dragged; If the load to be dragged is large, the actual power and actual current are large; if the load to be dragged is small, the actual power and actual current are small.

The rated power of the motor is not equal to the load power. Because when selecting the motor capacity, the future aging of the machine being dragged must be considered, so a margin must be added to the mechanical load power. The power level of the motor is not exactly equal to the calculated power of the machine, but the power level of the motor must be increased up, so the power of the motor is generally greater than that of the driven machine.

If the actual power and actual current are greater than the rated power and the rated current, the motor will be overheated and burned; The actual power and the actual current are less than the rated power and the rated current, which will cause material waste.

Their relationship is:- Rated power = rated current IN * rated voltage UN * root 3 * power factor. Actual power = actual current IN * actual voltage UN * root 3 * power factor

Insulation ‘facts and figures’ reference Shengzhou Liming small motors 

The insulation elements reference the company’s motor products includes the inter-strand, inter-turn, row, inter-layer and ground insulation of the coils, and various end supports or fixings of various insulation members and connection and lead insulation. 

The main insulation of a coil refers to the insulation between the coil and the body and other windings. It is also commonly called insulation to ground.

Interturn insulation refers to the insulation between turns of the same coil. Inter-strand insulation refers to the insulation between strands within the same turn, and is generally the insulation of the winding wire itself. The insulation of the motor is an important factor that determines the service life of the motor, so the insulation materials must be properly selected and placed. 

Asynchronous motor stator winding insulation is divided into slot insulation and phase insulation (interlayer insulation is not needed here). Slot insulation is used in the slot, which is the insulation between the winding and the iron core. 

Phase insulation, also called end insulation, is used for insulation between two windings at the end of the winding. Interlayer insulation is used for insulation between the upper and lower layers of the double-layer winding. The insulation material is the main insulation material selected according to the insulation level and voltage level of the motor, and is equipped with appropriate reinforcement materials to protect the main insulation material from mechanical damage. 

insulation materials 

Commonly used reinforcement materials are green shell paper, and the main insulation materials are polyester film and varnished cloth. When selecting insulation materials, the main insulation materials on lead wires, bushings, binding wires, dipping varnishes, etc. should be of the same insulation level and used together with each other.
