research and production

The Dongxing Telecommunication Material – a new IMD online member now – is an appointed China supplier to Amphenol-tuchel Electronics Gmbh, a world famous Telecommunication group and holds the ISO9001-2000 and ISO 14000 certifications for specialism in research and production.

The Company has a flourishing trade across China and also has a growing international market-place for its products – telecommunications; catering and household – to the U.S.A, U.K., Germany, South Korea, Japan, Canada and South-East Asia….. and more.

Spotted on the Dongxing Telecommunication company’s web site http://www.dongxing-al.com – an eye-catching industry news blog on cable re-cycling – a vital discussion point with many working within  telecommunications industries …

The story is that a lead cabling company is now using re-cycling cross-linked polyethylene used in cable insulation material for  insulation of its power cables. The company said this is a “significant step” in its ambition to reduce the carbon footprint of its low-medium- and high-voltage power cable solutions. Power cables are the backbone of the global power grids being crucial to the transition to renewable energy. For sure, indicate the NKT Company, the focus on sustainability in the power cable industry is constantly increasing.

The recycling process has been developed through a project with the Swedish research institute RISE IVF, AXJO Plastic and material specialist Borealis. In the past few years, NKT has industrialised the process of recycling XLPE in close collaboration with AXJO Plastic, which is now manufacturing cable drums from the recycled XLPE material. For sure it is said the benefits of the recycling are clear!

The material costs are significantly reduced compared with new raw materials and approximately two tonnes of CO2 are saved for every tonne of recycled material the company says. With recycling of XLPE from production sites in Sweden, Denmark and Germany say the Company, a significant step to decrease the carbon footprint and ensure a sustainable lifecycle of our power cable portfolio is being achieved.

Insulation often accounts for a substantial part of its power cables, and so NKT is working closely with material supplier Borealis to discover and develop sustainable solutions with XLPE material for the power cable industry. A stronger focus on sustainability in the supply chain is a natural step when reducing the overall carbon footprint of our power cables. With XLPE being an important material for high-performing power cables, it is good to see a closer collaboration with key supplier Borealis to continue to drive sustainable XLPE solutions.

‘Best foot forward’ for the fast-growing specialist Zhuji sock machinery company….

March 6th – The Zhuji Guanghui Machinery Co Ltd – another new member of IMD online –  is located in the “hometown of socks”- in Datang Town Industrial Park in Zhuji. The business is a modern enterprise. It is backed by innovative research and development and specialises in the creation and assembly of machinery for the production of hosiery.  

innovative 

The Company’s well-used and respected machinery products have been developed through innovative expertise and technology and are fully supported by advanced testing procedures. A leading product of the business which is of particular note is the highly successful, in demand, domestic computer flat, terry dual-use socks machine. 

techniques 

The progress and development of the business’ expert manufacturing techniques has enabled Zhuji hosiery machinery products to achieve wide recognition for their quality, effective design and reliable performance.

Led by its successful progressive management, Zhuji machinery products today compare favourably with any similar machines manufactured either in China or overseas. The Company’s thriving overseas markets currently includes The Middle East and South East Asia and also various other countries and Regions 

Here is a ‘quickie’ blog observation note ….regarding the historical development of the sock knitting machine – the forerunner- to an extent at least perhaps  – of the state of the art sock-producing machinery of the Zhuji Company…..

The first sock knitting machine was invented by the an Englishman, Mr Lee in 1589. It used crochet to produce shaped socks. In 1849, the single needle circular socks machine appeared and the tongue needle began to be used in small calibre within circular machines. 

Originally these machines produced tailored socks, but it was not until 1857 that weaving socks with pocket heels and toe caps began to be produced. In 1864, in Britain a Mr W. Cottonton invented the Cottonton socks machine -which was a crochet flat knitting machine. 

In 1900, double-cylinder circular socks machines emerged and knitted rib socks were introduced as double-headed tongue needles were applied to small-calibre circular-type machines. The neck top of the socks tended to be knitted by a special part of the hosiery machine, or even transferred to a special styled machine where it could be effectively manually finished. Hosiery, heeled socks and socks with soles and reinforced loops are now all knitted by modern socks machines.

‘Belting good’ products… …admired across the world, as Sanjia goes on expanding.. exporting and achieving…!

See this company’s entry in the IMD HERE.

International status 

Sanjia company products have an impressive home and international status and are sold throughout numerous provinces, cities and regions in China, and also exported to more than 50 countries and Regions world-wide including Europe, The United States, The Middle East, South East Asia, Africa and Australia. 

The Sanjia business – a recent new IMD online member – backs its exceptional quality production expertise, efficiency and technological innovation with attentive customer service, both at home and abroad. It is dedicated to a clear commitment to progress all of its business solution solving activities progressively so that it further develops ongoing momentum of its current achievements. Here below, Sanjia experts review key bonding issues relating to the heat resistant issue as it relates to conveyor belts …..

The bonding process of heat-resistant conveyor belts in production is one of the important factors affecting the bonding effect of conveyor belts. If the bonding process is not proper, it is easy to cause the heat-resistant conveyor belt to tear and open, which greatly shortens the service life. The following conveyor belt manufacturers take a detailed look at the bonding process of heat-resistant conveyor belts.

The heat-resistant conveyor belt agent bonding process generally includes surface treatment, gluing, drying, gluing, curing, etc. of the adherend, which is relatively complicated and has many influencing factors. Therefore, the bonding must be performed according to the correct process; Properties, which share interlayer cations and are compact with each other, a series of composite materials of clay polymer nano-rubbers with excellent properties are prepared, and the so-called intercalation compounding inserts monomers or polymer molecules into the layered silicate In the nano-space between the layers, the layered silicate is peeled into nano-structure units or micro-regions by polymerising or shearing force and uniformly dispersed in the polymer matrix.

The direct adhesion method of heat-resistant conveyor belt refers to the method of directly adding adhesives to the rubber compound and curing the interface by vulcanisation to achieve bonding. Commonly used direct bonding systems mainly include methylene white, organic cobalt salts, and over-vulcanisation stability Agent, white carbon black and other systems, antioxidants can improve the adhesion of rubber and steel wire while protecting, and cobalt salt of organic acid can act as an adhesion promoter when bonding rubber to brass or galvanized steel cord or rope.

The inter-calation composite method is a method for preparing polymer layered silicate nano-composites. First, a monomer drum polymer is inserted between the layered silicate sheets treated with an inter-calator, thereby destroying the silicate sheets. The layer structure makes it peel off to become the basic unit of layered silicate, and is evenly dispersed in the polymer matrix, so as to realise the composite of polymer and clay-like layered silicate on the nanometer scale.

Advantages 1. Light body is very small: LED light is a very small, very fine LED chip packaged in a transparent epoxy resin, so it is very small, very light, in the production and application saving a lot of materials and space.

Advantages 2. Very low energy consumption: generally, the working voltage of LED lamp is only 2-3.6v, and the working current is only 0.02-0.03a. That is to say, the power consumption is not more than 0.1W, which is more than 90% less than that of incandescent lamp with the same light effect, and more than 70% less than that of energy-saving lamp. Therefore, only LED can be called a real energy-saving light source!

Advantages 3  Solid and durable: LED chip is completely encapsulated in epoxy resin. The small epoxy resin particles are very difficult to break, and the whole lamp body has no loose part; the chips inside are very difficult to break, and there is little thermal effect that may volatilize and fuse. These characteristics make it difficult to damage the LED light. Compared with ordinary light bulb and fluorescent lamp, LED is solid and durable.

Advantages 4. long service life of LED lamp: under the appropriate current and voltage, the service life of LED lamp can reach 100,000 hours, that is to say, the product life can reach more than 10 years in theory, with longer service life than other types of lamps.  For an even more extended list of advantages, visit www.lucoh.com 

Zhejiang Xier Plastic valves are repairable.. and ‘we will repair them’ explain the Xier experts…

The Zhejiang Xier Plastic Valve Lead Co Ltd, formed in 1993 and located in Zhejiang Province, China,  is a leading, long established, manufacturing and trading company of PVC and PPR Ball Valve products. 

highly professional expertise 

It’s factory facility contains 64 injection machines used to produce the business’ highly successful Ball Valve products. Xier Plastic has a long-standing and highly professional expertise and experience in the development and manufacture of varied ball valve technology and production, and is known for its products world-wide. 

The business – a recent new member of IMD online – continues to invest in Ball Valve making and moulds in order to remain totally responsive to all customers’ development requests, however complex and demanding they may be.  Here below, their experts review the issue of repair to their PPR Ball Valve products should they become damaged … 

When PPR Ball Valves become damaged and start leaking water then most suppliers simply replace the damaged valve with a new one. It is true, many think that valves such as these are unable to be repaired and tend to think the only answer is to spend money replacing them.

We at Xier would say this is not the case. Most valve service providers may not provide a PPR Ball Valve Repair service and they usually prefer to replace it, but these valves are repairable and this applies to the each of the three general types of ball valves whatever their bore sizing type…….

The full port valve has a large ball, and the hole is the same size as the pipe resulting in minimum friction loss. Flow is unrestricted, but the valve is larger.

In a decreased or reduced bore ball valve flow over the valve is one pipe size, smaller than the valve’s pipe size, resulting in flow area becoming lesser than the pipe.

A V-port ball valve has a closer limited flow characteristic. This type of valve needs to be more robust in production, due to the greater velocities of the fluids going through it and the volume is a key factor in a valve becoming damaged. 

Those are the key three bore size types and each can be repaired…. and Xier will repair them in all reasonable circumstances. Visit ….www.xier.com

Specialist, non-ferrous metal product manufacturing business, Baoji Hanz review the key strategic product of tungsten…..

March 4th – Latest IMD online member, Baoji Hanz Material Technology Co Ltd, located in Baoji city of Shaanxi Province in China, is a producer of cost-effective, non-ferrous metal products such as sheets, plates, cubes, pipes, bars and wire, which are used in various fields and industries including geology, petroleum, chemical, medical and also military. The high-range metals used in the Company’s specialist expertly-developed products are in the main titanium tungsten and molybdenum….here Baoji company’s research experts ‘blog’ their review of key aspects of Tungsten products usage  …..

Tungsten products mainly include tungsten concentrate raw materials and ammonium paratungstate, tungsten oxide, tungsten powder, hard alloy, tungsten bar, tungsten wire and tungsten, iron and so on, widely used in automobiles, machinery, mining, petroleum, building materials, electronics, military and other fields. The analysis of tungsten industry indicates that tungsten has been listed as an important strategic metal in the world because of its irreplaceable role in many fields. 

demand grows 

From the domestic market, tungsten raw material market supply tends to be stable, demand continues to grow, the trend of tight supply has not changed.

With the establishment of the ecological protection red line, the strengthening of the exploitation and management of Tungsten Mines, the implementation of the policies on the prevention and control of pollution from tungsten smelting, the environmental protection tax and the resource tax law, etc…

decrease 

Due to the rigid increase of tungsten mining cost, the decrease of tungsten ore grade, the expansion of tungsten mining capacity and the control of mining rights, the resource and environment constraints are becoming stronger and stronger. At present, China’s tungsten industry is in a critical period of high-quality development, the industry’s economic situation needs to be further consolidated.            

legal system 

First, may be to speed up legislation on mineral reserves and improve the legal system for strategic reserves of mineral resources; Second, best to perhaps strengthen organisational management and establish an operational mechanism for mineral reserves; and third, continue to strengthen the control and management of the total amount of mining, to create favourable conditions for the reserve of tungsten resources, and to give full playtime the role of trade associations in the implementation of the reserve of tungsten resources.

These machines offer varied weaves for safety gloves production and are a sound investment due to their high degree of effective automation. Below, the business’ experts review different, varied weaving methods to be tackled by its exceptionally well-regarded machines…..

The knitting production process is short – the material has strong applicability, the product has a wide range of use, the needle strong machine has high production efficiency, low labour intensity, low machine noise and small floor space.

The coil is the basic structural unit constituting the knitted fabric. Coil composition: circle, needle arc and sinker.The main physical and mechanical indicators of knitted fabrics: coil length, density, under-fill, co-efficient thickness, dispersibility and curling.

The type of needle, – it can be divided into crochet machine, tongue needle machine and compound needle machine. The knitting machine should be composed of:- a wire or a feeding mechanism, a weaving mechanism, a pulling and winding mechanism, a transmission mechanism and an auxiliary mechanism. Auxiliary devices include:- flower type mechanism, automatic control mechanism, automatic fuelling device, cleaning dust removal device, various self-stop devices, counting devices, etc..etc..

Type of knitted fabric:- original tissue, changing organisation, flower colour organisation, flat needle tissue, a double rib structure, commonly known as cotton wool tissue.

The method of representing the structure – reference weft-knitted fabric generally includes-  A structure diagram, an artwork diagram, a weaving diagram. Jacquard organisation, whose structural unit consists of coils and floats. Jacquard tissue can be divided into single-sided, double-sided, which has a monochromatic (plain) and multi-colour. 

Single-face weft-knitted jacquard, according to the number of vertical turns of the longitudinal coils of each front coil in a complete group strength, can be divided into two types: uniform structure and uneven structure.

There are three major categories of colour-added yarns: embroidered yarn-added tissue, overhead-stacked tissue, and exchange-stamped tissue. The laying method of the padding yarn is generally straight pad type, displacement type or hybrid type. At present, most of the flannel production adopts 1:2 displacement type.

The experts know ….. read the below blogged key assessment from the Eura Mould expert team on mass producing mould products ….

“If a manufacturer wants to ensure that all products are exactly the same when mass-producing various products, then they must use moulds for production. Thus, they also need to find some professional mould design and manufacturers. In order to provide high-quality moulds to their customers, these manufacturers will probably introduce new design and manufacturing processes. For the current mould field, what are the design and manufacturing processes used? Being are a practitioner in this industry, then we of course have a deep understanding of this knowledge, so let’s take a look below and review issues below..

First, casting

Most people should be familiar with the casting process, and to a certain extent, most people think that all moulds are produced by casting. In fact, in the process of mould design and manufacturing nowadays , this production and manufacturing process is no longer applicable. This is because it may cause poor thermal conductivity of the mould, and so will affect the overall production result. The most important thing is that this casting method may also affect the steel strength and hardness.

Second, cutting

For those moulds that require a certain degree of excessive rounded corners, cutting can be used in the production process, because doing so can effectively guarantee that there is a certain degree of radian at the corners.

Of course, in terms of technology, it also has certain defects. For example, during processing, it is likely that the stress concentration will occur due to the very small radius, which can further damage the materials used, and may also cause the appearance of this mould to be too rough after processing.

Third, grinding

This is a mould design and manufacturing process that is often used at present, because for this production process, it can effectively improve the quality and level of the mould. The most important thing is that some moulds have higher requirements for precision, especially The requirements for the smoothness of the mold surface are also relatively strict. Therefore, in some cases with high requirements, this tool can be used to complete the mould design and manufacturing work. However, when applying this process, care is needed to avoid overheating or cracks.

Fourth, EDM

In fact, for most mould manufacturers, in the process of designing and manufacturing various moulds, due to the high requirements on the accuracy of the mould, the EDM process seems to be more and more popular – after all, it is being controlled numerically. Technical control of EDM can achieve higher accuracy, and at the same time can ensure that the surface has a certain degree of smoothness. However, when applying this mould design and manufacturing process, the operator must have a certain level of technology knowledge as this process has certain requirements on a technical level.

The various mould design and manufacturing processes introduced above each have their own characteristics. It cannot be said which process is the best, but for different mould types, different production and manufacturing processes may well be required.

Getting conditions just right for quality precision effective moulds – Taizhou Huangyan know how….

March 3rd – The Taizhou Huangyan HAOHAO Plastic Mould Factory was founded in 2008 and has over 200 staff. It is yet another Chinese member of IMD Online. Its business centre, covers an area of 17,000 square meters and the business holds the ISO9001 certification and uses advanced CAD/CAN systems.

advanced technology 

It operates a high-precision CNC machine centre, backed by advanced technology and is equipped with top range machinery. An extensive range of high quality, middle and large sized moulds are produced by the company at competitive prices for use in the auto, electricity, daily necessity and other industries. 

Mould types produced include cable tie; auto; air cooler; pipe fitting and more.  Varied quality moulds are produced according to pattern samples, 3D drawings or to die casting and small precision mould patterns. Here below, the Company’s experts reflect on the requirement of the right working conditions for effective plastic moulds …

Abrasion resistance

When the blank is plastically deformed in the mould cavity, it flows and slides along the cavity surface, which causes severe friction between the cavity surface and the blank, which causes the mould to fail due to wear. Therefore, the wear resistance of the material is one of the most basic and important properties of the mould.

Hardness is the main factor affecting wear resistance. In general, the higher the hardness of the mould parts, the smaller the amount of wear and thus the better the wear resistance. In addition, abrasion resistance is also related to the type, quantity, form, size and distribution of carbides in the material.

Toughness

Most of the working conditions of the mould are very harsh, and some often bear large impact loads, which leads to brittle fracture. In order to prevent the mould parts from being suddenly brittle during work, the mould must have high strength and toughness. The toughness of the mould mainly depends on the carbon content, grain size and microstructure of the material.

Fatigue fracture performance.

During the work of the mould, under the long-term effect of cyclic stress, it often causes fatigue fracture. Its forms are small energy, multiple impact, fatigue fracture, tensile fatigue, fracture contact, fatigue fracture and bending fatigue fracture. The fatigue fracture performance of a mould mainly depends on its strength, toughness, hardness, and the content of inclusions in the material.

High temperature performance

When the working temperature of the mould is higher, the hardness and strength will be reduced, leading to early wear of the mould or plastic deformation and failure. Because the mould material should have high resistance to tempering to ensure that the mould has a higher hardness and strength at the working temperature.

The complex matter of the right material prepared in the right way for the simple pocket ….

March 3rd – Huzhou Deer Textile Co Ltd  – a recent new IMD online member – is a leading international enterprise specialising in the development and manufacture of top-quality lining fabrics. Located in Huzhou Zhengjiang Province, close to Shanghai port, the business’ achieves an annual production volume of fabric of more than a mammoth 500,000,000 metres!

The company exports most of its ‘material’ products to the likes of Europe, Russia, The Middle East, South Asia, Korea, Mexico, Columbia, Panama and more and its international market continues to grow year on year. The business develops, creates and even leads new products for every overseas ‘fashion season’. It  now produces over 1000 high standard, quality controlled different lining fabrics routinely every year, as well as products developed specifically to order.  

Huzhou Deer Lining material is a key product too when it comes to the humble pocket, (which most garments have of course!)….Here below their experts ‘blog-talk’ pockets – and it is apparently as you will observe – quite a complex matter……

The fabric of the pocket fabric is divided into two parts by the warp of the two systems – The tissue of a system of warp yarns is called the weft double structure. The fabric is woven with the same structure, and the same or different appearances of the front and back sides of the fabric can be obtained. The strips or patterns of different colours can be obtained on both sides of the fabric, and the double-layered tissue is often used for weaving high-grade combed wool fabric, and heavy tissue is often used to weave fabrics such as felts and heavy woollen fabrics.

The pocket cloth polyester-cotton weave –This is interwoven by the warp yarns of the two systems and at the same time, the upper and lower layers of fabric are formed parallel to each other. The two layers of fabric may be separated from each other or may be connected to each other. A tubular fabric can be formed by joining only the two sides of the upper and lower layers. By connecting only one side of the upper and lower layers, a double fabric can be woven on a narrow loom. Huzhou Deer’s pocket fabric(pocketing fabric) has guaranteed quality.

Two or more colour yarns are used – This is the warp and weft yarns, and the inner layer of the watch is exchanged according to the design pattern, and the pattern of the colour change in the table can be obtained. The upper and lower layers are affixed together to obtain a double layer fabric. Two-layer tissue is commonly used to weave thick fabrics, paper blankets and other wool fabrics. It is the same for double-layer uppers and fire hoses and other cotton fabrics.

The pocket cloth polyester-cotton weave – This is composed of two system warp yarns and a system weft yarn, or a system warp yarn and two system weft yarns (known as a ground weft, hair weft). The former is formed by warp yarns forming the surface of the fabric, which is called a ‘pile fabric’, and the corresponding tissue is called a raised structure.

The latter consists of a weft yarn – This forms a pile surface of the fabric, and the corresponding tissue is called a weft raising structure. When woven by the raised fabric, the upper and lower layers of the ground fabric are simultaneously formed on the loom, and the distance between the two layers is the height of the two layers of the pile. The fabric is divided into two separate raised fabrics after being cut. Fabrics such as flat and plush are woven with raised tissue.
