What Conditions Need To Be Met For Injection Molding Production

Due to the ultra-high fluidity of plastic, it will cause certain errors between the plastic parts produced by injection molding and the drawings, especially for some injection molded parts that require relatively high dimensional accuracy.


There are many factors in the production of injection molding that will affect the accuracy of injection molded parts. The first is the manufacturing accuracy of the injection mold and the degree of wear of the mold. The second is the fluctuation of the plastic shrinkage rate and the change of process conditions during the injection molding process. Aging changes and the structure and shape of the mold, etc.

In fact, there are many products that have not reached the service life at the beginning, and there will be many factors. One of the reasons is that the product parts cannot reach the size of the design at the beginning. A complete product consists of several or even Composed of tens of thousands of parts, the size fails to meet the design requirements, causing problems in the process of use.

In recent years, the precision injection molding processing and production industry has developed relatively rapidly. So what are the general requirements for meeting the conditions of precision injection molding processing and production?

1) With advanced injection molding machine equipment, injection molding machine is the cornerstone of injection molding, just like building a house, if the foundation is unstable, the house is at risk of collapsing.

2) Injection mold manufacturing, injection molding processing production industry is inseparable from injection molds, injection molds with superior performance can add a lot to precision injection molding production.

3) Injection molding processing and production operations, without an excellent injection molding processing and production engineer, even the best injection molding equipment is futile.

4) Purchasing raw materials for injection molding processing, even if it is the same type of plastic, different processing and production processes will result in different performance of injection molded parts.
