Methods to identify high quality injection molds

When customers are looking for a job to making injection molds, what they are most worried about is the processing quality of the injection molds. Generally, our molds are customized. Customers provide samples or drawings to the mold factory, and then the mold factory processes and produces them. For customers who are not particularly proficient in injection molds, how to identify high-quality injection molds is a difficult problem. Sometimes it seems that there is no problem with the mold itself, but the actual product produced by the mold may not be qualified. The identification is introduced below Quality mold method.
 
1. The polishing performance of the mold cavity surface must be excellent, so that the surface roughness value is minimized. Injection mold processing manufacturers should have good polishing workshops and equipment to ensure excellent polishing of the mold. 
2. The mold must have good thermal stability. After the mold is quenched, the size of the mold must be kept basically unchanged. This is very strict on the process requirements of injection mold processing manufacturers.
3. The mold surface must have sufficient hardness and excellent wear resistance. This requires that the injection mold manufacturers have certain requirements for the selection of injection mold materials in the early stage.
 
In addition, the most important thing is to see if the size of the injection molded product is acceptable. If the product meets the requirements, it also depends on the yield of the product, such as a 10-die inspection or a 20-die inspection. If the scrap rate is high, the mold is still not qualified. You can also check the steel certificate of the mold, heat treatment certificate, and the supply information of the accessories. If you still have questions, please consult Changzhou injection mold processing , we are happy to help!
