Influence of grinding processing on service life of plastic mold spare parts

Manufacturing is a continuation of mold design and is the process of verifying the correctness of the design. In the manufacture of modern plastic mold spare parts, the grinding processing accounts for 25% to 45% of the total working hours. The following YIZE MOULD will tell you the influence of grinding processing on service life of plastic mold spare parts.

Influence of grinding processing on service life of plastic mold spare parts



As we all know, the quality of finished products of plastic mold parts is closely related to the manufacturing precision, especially the precision and surface roughness of the mold cavity surface. So, what are the influence of grinding processing on its life?



In actual production, the factors that affect the quality of mold parts are:
Mold structure, mold material, manufacturing process of hot and cold

processing (forging, heat treatment, cutting, grinding, electric machining, etc.) and mold working conditions.In order to improve the life of the mold, it is necessary to carefully analyze the causes of the damage to the mold and various influencing factors, and formulate methods and measures for overcoming.

How to reduce the influence of grinding processing:
1.Selecting appropriately the grinding dosage
2.Selecting and trimming appropriately wheel
3.Using appropriately cooling lubricating liquid
4.Electrolytic grinding process is used to improve mold precision and surface quality.



In a word, the grinding processing should be paid full attention to in the manufacture of plastic mold spare parts, so that the grinding micro-cracks and residual stress can be reduced to the minimum, so as to improve the service life of the mold.
