Process issues with lost foam casting

1. Some manufacturers' introduction of lost foam casting technology is not cautious or scientific enough, lacking in-depth understanding of lost foam casting by professional personnel, unclear target products, or insufficient demonstration of the technical feasibility and economic rationality of the products; Without a complete feasibility analysis report, hastily initiate the project .

2. Enterprise leaders have high expectations for the new technology, but there are not enough technical personnel within the company to digest this technology, resulting in limited practice and unstable production.

3. The lost foam casting process of most manufacturers is still very rough. Although it seems simple, the actual number of process steps to be controlled greatly increases. We basically use the simple method of initially making wear-resistant parts to make more complex castings, molds, pouring systems, etc., without strict process regulations.

4. Lack of strict quality assurance system and strict process management.

Our technological accumulation is still limited and not stable enough.

6. The quality of raw and auxiliary materials is not poor and not stable enough.

7. The level of the transferring unit is not high, which affects the approval of the production unit.

Due to market factors, some units have stopped production due to intense changes in the market, and their ability to develop new products has limited the speed of production conversion.
