- The introduction of lost foam casting process by some manufacturers is not cautious and scientific enough, lack of in-depth understanding of lost foam casting by professionals, unclear target products or lack of sufficient demonstration of technical feasibility and economic rationality of products; Without a complete feasibility analysis report, the project was approved in a hurry.
- The enterprise leaders have high expectations for the new process, and there are not enough technicians in the enterprise to digest the process. There is little practice and can not stabilize the production.
- The lost foam casting process of most manufacturers is still very rough. lost foam casting seems to be simple, but the actual process links to be controlled are greatly increased. Basically, we still use the simple method of making wear-resistant parts in the initial stage to make more complex lost foam castings, rough molds, gating systems and so on, and there is no strict process specification.
- Lack of strict quality assurance system and strict process management.
- Our process accumulation is still small and not stable enough.
- The quality of raw and auxiliary materials is not poor or stable.
- The level of the transfer unit is not high, which has an impact on the production unit.
- For market reasons, some units stop production due to drastic changes in the market, and the development capacity of new products restricts the speed of changing production.
