        Product Details
        The complexity of the precision casting process determines that each process in the production process must be equipped with a full-time inspector to conduct the first inspection, patrol inspection, and final inspection. Firstly, control and find out the reasons for the unqualified products, secondly control the flow of unqualified products in this process, and finally control the unqualified products not to be transferred to the next process.
        1. Wax mold pressing quality control
        Ambient temperature: -26℃;
        Pressing temperature: 55~60℃;
        Pressing time: It depends on the structure and size of the wax model, usually a few seconds to a few minutes;
        Suppressing pressure: It depends on the structure and size of the wax mold, generally 1.2MPa.
        2. Wax model repair and cooling quality control
        The quality of wax mold repair depends to a large extent on the proficiency and experience of the operator, and the training and education of the operator should be strengthened. The repaired wax model shall be fully inspected.
        Since the wax mold takes a long time to completely cool down in the air after being pressed, special fixtures must be set up to prevent the wax mold from deforming and reduce the workload of the subsequent process. In this regard, Japanese precision casting companies have done relatively well. Every year, our company sends staff to Japan to visit and learn to learn from its strengths and make up for our shortcomings. Only in this way can we continue to move forward.
