Lost foam casting equipment introduction
 

On the basis of advanced technology around the world, this Lost foam casting equipment which is combined with China's national conditions and practice meets the technological requirements. Meanwhile there are many outstanding features such as small investment, quick effectiveness, labor saving, stable performance, flexible production, wide range of applications, etc. Lost foam casting equipment is ideal for new and old commercial foundry to reform technique.

Production principle:

According to the process, this method makes foam plastic pattern (manual, mechanical) first, and then smear some special coating. After drying, place in a special sand-box and fill in dry sand. Three-dimensional vibration is tough. When casting begins in vacuum condition, model gasification disappears. Liquid metal will replace the pattern and duplicated castings as the foam plastic pattern come into beings.

 

Process flow:

1. Make white pattern of the foam plastics and pour system together; Gasify brush of white pattern; Spray special hear-resistant coating before drying.
2, Place the special interlayer sand box on vibration worktable; fill in the bottom sand (dry sand); Then compact and strike off; Put the dried evaporative pattern on the bottom sand and fill in dry sand;Strike off the box outlet after suitable micro-vibration.
3, Cover with plastic film; put a pouring cup; The vacuum system inhales vacuum; After dry sand are fastened and molded, begin casting; White pattern disappears and liquid metal replaces it.

4, Release the vacuum; Turn over the box after the casting is condensed; Take the casting out of the loose dry sand. Proceed to the next cycle.

 

Technical advantages:

EPC process sets full mold casting, advantages of v-process casting process as a whole. Lost foam casting equipment is suitable for cast steel, cast iron, bronze, cast aluminum and other brands, as well as all kinds of material, different structures and size( large, medium and small ) of all kinds of castings. The type is fixed by dry sand, and the prototype is original. The casting is highly precise, uniform and no less than core, and not to box, and the casting is not Burr. The smooth of the surface is close to precise casting. Its internal structural is stable, which remove and reduce the defects such as blowholes and gas air. There are two level of environmental treatment throughout the production process, so as to get rid of pollution.

Scientific findings:

To sum up, the EPC in line with overall trends in today's casting technology development, as well as bright prospects. Compared with traditional casting technologies, EPC technologies has unparalleled advantages. In 1999, the National Ministry of science and technology focused on the promotion of EPC technology in national high-tech. It is foundry industry at home and abroad as the "casting technology of the 21st century", "casting industry of green revolution".

Product installation services, technical services and after-sales service:
If you order the EPC equipment, we will be responsible for giving reasonable manufacturing shop's layout, and the installation, commissioning according to buyer's plant actual conditions, and training buyer's workers operating specifications, ratio of paint, and paint, trial production of qualified products. Due to the characteristics of the device itself and a wide range of casting, We will commit ourselves to the process of casting equipment service.
