Injection molds making

 

According to the size of the production capacity, product structure, to determine the appropriate number of cavities, more precision molds, processing difficulty, the higher the cost of the mold cavity. However, the unit price of injection molded parts dropped significantly. Factors that affect the size of the multi-cavity:

1, precision injection mold processing. Such as cavity discharge, each chamber is a discharge, the discharge process is not well controlled, cavity size deviation.

2, the injection mold assembly precision. Because of the reasons of the assembly results in the internal structure of position deviation.

3, Injection mold design factors, such as whether the design of the flow channel and reasonable uniformity into the plastic, unreasonable runner advanced gum near the nozzle chamber, away from the last-glue because contraction inconsistent, holding pressure situation size will also inconsistent deviation. Into the rubber mouth diameter size will cause the size of the deviation. Mold waterway design is unreasonable, in the cavity waterway lay .

Mold waterway design is unreasonable, in the cavity waterway layout should be uniform cooling, if unreasonable, the different parts of the mold at different temperatures, resulting in shrinkage, and thus the size of the deviation. All in all, a multi-cavity mold size deviation basic mold.
