What about Multi Cavity Injection Moulds Making
Multi cavity mould is according to the size of the production capacity, product structure. It determines the appropriate number of cavities, more precision molds, processing difficulty. The higher the cost of the mold cavity. However, the unit cost 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. The unreasonable runner advanced gum near the nozzle chamber, away from the last-glue because of contraction inconsistent. Holding pressure situation size will also inconsistent deviation. Into the rubber mouth, the diameter size will cause the size of the deviation.
4, Mold waterway design is unreasonable, in the cavity waterway lay. 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.

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 of contraction inconsistent, holding pressure situation size will also inconsistent deviation. Into the rubber mouth, the diameter size will cause the size of the deviation.
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. Little effect of the injection molding process.out should be uniform cooling.
