                        What is a precision casting?






Among the precision castings, investment casting is also commonly used. It is also called lost wax casting. It is made by using suitable investment materials (such as paraffin) to make investment molds. Repeated refractory coating and refractory sanding process on the investment mold, hardened shell and drying Then, the internal melting mold is dissolved to obtain a cavity; the calcined shell is obtained to obtain sufficient strength, and the residual investment material is burned off; the metal material required for casting is poured; the solidification is cooled, and the sand is removed after shelling, thereby Get high precision finished products. According to product needs or heat treatment and cold processing and surface.

                    Understand the importance of defects in precision castings     In actual production, it is often necessary to analyze casting defects, the purpose of which is to find out the cause of the defects so that measures can be taken to prevent them. For precision casting designers, understanding product defects and causes can help to properly design the casting structure and combine the actual conditions of the casting production to properly formulate the technical requirements. There are many defects in precision castings , and the defects and causes are very complicated. Sometimes, defects caused by many different reasons appear on the same casting, or the same reason may cause various defects when the production conditions are different. Whether a defective casting with defects is classified as waste must be determined according to the use and requirements of the casting and the location and severi...
