Injection molding is only the processing of plastic products. If it is the production of prototypes, 3D printing and silicone molding are selected, but it will be used for mass production.

What are the causes of dents in plastic mold processing

As a processing technology, plastic mold processing, after its production or completion, will be somewhat defective. How to solve this situation? 1. Dent. The causes of dents are: 1) Insufficient cooling of the mold, insufficient cooling time will cause serious deformation. 2) This situation also occurs when the internal pressure of the mold is insufficient….

What are the characteristics of precision injection processing molds ?

1. Wear resistance When the blank is plastically deformed in the mold cavity, it moves and slides along the outside of the cavity, which causes intense friction between the outside of the cavity and the blank, thereby inducing the mold to take effect due to wear. Therefore, the wear resistance of the material is one…

Main influencing factors of various failures of precision injection molding

The basis for determining precision injection molding is the accuracy of the injection molded product, that is, the dimensional tolerance, shape tolerance and surface roughness of the product. There are many relevant conditions for precision injection molding, and the most essential are the four basic factors of plastic materials, injection molds, injection molding process and…

How to reduce defects in engineering plastic products mold processing

1. Reasonable use of cooling lubricant, play the three major roles of cooling, washing and lubrication, keep cooling and lubrication clean, so as to control the grinding heat within the allowable range to prevent thermal deformation of the workpiece. Improve the cooling conditions during grinding, such as the use of oil-immersed grinding wheels or internal…

Analysis of the reasons that affect mold precision injection processing

The mold designer must have rich design and injection molding experience. For precision mold processing, the relationship between these influencing factors and the injection conditions and their apparent factors must be considered, such as injection pressure and cavity pressure and filling speed, injection melt temperature And mold temperature, mold structure and gate form and distribution,…

Talk the surface treatment

1: anodizing In order to enrich the color of the product, we can usually make some oxidation treatment. The oxidation treatment can make all the colors except white. The oxidation treatment is done for the aluminum alloy. If it is other materials, it can’t make anodization. Steel material, you can choose plating, etc. anodized aluminum,…
