Precision casting is a high-precision, high-quality casting process for the production of parts with high requirements for dimensional accuracy and surface quality;  

After melting and casting, the product together with the die head is wrapped by the shell mold, which needs to be removed through the process of shell vibration and lifting and casting. As a large amount of dust will be generated during the working process, proper protection is essential to ensure the health of the employees.

During the precision casting process,Roasting and melting are connected processes, completed by the same group of personnel, the roasting process, the temperature of the shell mold, dryness and other factors directly affect the quality of the final casting, melting and pouring process, the temperature of the molten steel, slag removal, deoxidation and other factors also play a decisive role in the quality of the casting and the qualification rate,The two processes are also the root cause of many quality problems in the investment casting process, so how to control these two processes will directly determine the quality of the product.

Final inspection process as the last stage of the production process, its purpose is to set up inspection standards, the use of reasonable testing tools, so that the defective products before shipment can be intercepted in the factory, to improve product qua...

For the EGR cooler in the automobile exhaust gas treatment system and the sea and fresh water heat exchanger for ships, the precision castings are usually hermetically sealed parts; therefore, in the manufacturing process, the sealing inspection process is essential to ensure that the sealing performance of the precision castings meets the design requirements, and through the sealing inspection, the casting defects such as porosity and cracks in the precision castings can be identified, so as to make the defective products intercepted in the manufacturer's internal, to ensure that the client's components will not leak or fail in the process of use.
