In the past, customers used sand casting process to produce hammer head, chain joints and other castings on site, which has many problems such as low production efficiency, poor working environment, high labor intensity of workers and poor surface quality of products.  With the rapid development of epc process in China and the advantages of low labor cost, energy saving and environmental protection, and good surface quality, people began to try to use EPC to produce this kind of castings.  

Forklift shovel tooth, as its name implies, is a kind of accessory on forklift. Its special working environment requires shovel tooth to have good wear resistance as well as good strength and toughness. Therefore, material selection, casting process design and pouring process control play a key role and influence on product performance.

In this paper, the flywheel, table is 65 tons of high speed punch used. A series of technological measures were adopted to solve the difficulties in producing this kind of high end castings for export.

This paper introduces the lost mode casting process of single cylinder wheel of diesel engine, and introduces the process performance of single cylinder wheel from white zone, yellow zone and black zone.

The production of ductile iron pipe fittings by epc process has considerable advantages. There are many kinds of pipe fittings. The problem of burying pipe fittings of different specifications is solved by the versatility of epc sand box.

The lost foam process control plan for pump casing is mainly a control plan for the entire process based on the casting quality standards provided by the customer. Everything needs to be based on the customer's product quality requirements, and the product quality control that needs to be carried out in each link is derived according to this standard.

The material of the transmission housing for agricultural machinery is HT250, and it has a relatively complex structure. It is produced by the lost foam casting process. Although it is generally easy to cast as a whole, many problems still occur during the actual production process.

The Hubei customer's 3000T lost foam casting production line mainly produces ductile iron shell castings such as rear axle main reducer, middle axle main reducer, and bridge box. With the joint efforts of both parties, the complete process of lost foam casting in black, white, and yellow areas was determined, and the normal operation of the production line was achieved. This production line is our company's first fully automatic separation pouring production line, which reduces equipment investment and improves production efficiency. The entire line adopts PLC automatic control, with a high degree of automation.
