Experts Zhuji Edd ‘casting’ an eye over the variety of casting types so important these days …..

We are pleased to welcome this week to IMD yet another specialist machinery business from China –  Zhuji Edd Machinery. They are an international enterprise manufacturing numerous types and styles of castings  including continuous, sand, centrifugal and die castings finished  in the likes of copper, steel and aluminium.  

experienced and expert

Having its own copper casting foundry and CNC machining factory, the business is able us to supply both precision castings and finished products. The company operates advanced quality testing equipment for constant full chemical analysis. 

The business has an experienced, expert management team ensuring an attentive, successful and secure after-sales service. Owing to the high quality and fair pricing of its products and services Zhuji Edd have a clientele from across the world including  The United States, Germany, South Korea and numerous  Middle East countries.


Zhuji Edd clients include many OEM customers across many industries –   air-conditioning , coal and gas, ceramics, chain production, transmission parts production, textiles and construction and the variety of casting type is a fundamental today for Zhuji Edd and the development of technology, they say, has made more and more casting processes available nowadays such as pressure casting, precision casting, vacuum casting, etc., and the selection of the process is not only to measure the characteristics of the process itself, the most critical match between the two, that is, the process 

pressure casting 

Can it be consistent with the material properties and manufacturing conditions. So what kind of casting production is mainly applied to pressure casting? It has been found through practice that the following materials can be used for pressure casting, including tin, lead, zinc, aluminum, magnesium, copper alloys, and the like. Due to the limitation of the capacity of the die casting machine, not only the type of material but also the weight of the material is required. Since the production speed of pressure casting is very fast, it has been widely welcomed. Even so, it is not possible to use pressure casting blindly. Before the operation, it is necessary to do the relevant inspection work to ensure that the casting after moulding can reach the best condition.

Different Casting methods for different castings

Casting methods, casting methods of different castings are also different, commonly used is sand casting, followed by special casting methods, such as: metal casting, investment casting, gypsum casting, etc. Sand casting can be divided into clay sand type, organic binder sand type, resin self-hardening sand type, lost mould and the like. There are, say Zhuji Edd, key principles of casting method selection…

Sand casting is preferred, mainly because sand casting has lower cost, simple production process and shorter production cycle than other casting methods. When the wet type does not meet the requirements, consider using a clay sand table dry sand type, dry sand type or other sand type. 

Clay wet sand castings can weigh from a few kilograms up to tens of kilograms, while clay dry castings can weigh up to tens of tons.The casting method should be compatible with the production batch. Casting methods such as low-pressure casting, die-casting, and centrifugal casting are only suitable for mass production because of the high cost of equipment and moulds.

factory conditions 

Modelling methods should be suitable for factory conditions. For example, it is also the production of castings such as large machine bed, generally adopting the core forming method, not making the pattern and the sand box, and assembling the core in the pit; while the other factory adopts the sand box modelling method to make the appearance. Different production conditions (including equipment, site, staff quality, etc.), production habits, and accumulated experience vary. It is appropriate to consider what products are suitable and what products are not suitable (or not and attention must be paid to the precision requirements and costs of castings
