Process problems with lost foam casting

1. Some manufacturers are not cautious and scientific enough to introduce the lost foam casting process, lack of professional in-depth understanding of lost foam casting, unclear target products or lack of full demonstration of the technical feasibility and economic rationality of the products; In the absence of a complete feasibility analysis report, the project was rushed [5].
2. The expectations of enterprise leaders for the new process are very high, and there are not enough technical personnel in the enterprise to digest this process, and the practice is small, and the production cannot be stable.
3. Most manufacturers of lost foam casting process is still very rough, lost foam casting seems simple, the actual process to control greatly increased, we basically also use the initial simple method of anti-wear parts to make more complex castings, molds, pouring systems, etc. rough, there is no strict process regulations.
4. Lack of strict quality assurance system and strict process management.
5. Our process accumulation is still very small and not stable enough.
6. The quality of raw and auxiliary materials is not poor and not stable enough.
7. The level of the transferred unit is not high, which affects the production unit.
8. Market reasons, some units, due to the drastic changes in the market caused by the suspension of production, new product development capabilities restrict the speed of production.
