Five Steps in the Manufacturing of Mold for Plastic!

Table of content

1. Analysis of plastic parts of mold for plastic

In the mold design, the engineer of mold for plastic should fully analyze and study whether the plastic parts meet the mold opening requirements. The geometric shape, dimensional accuracy, and appearance of the product should be considered, and the engineer should discuss, try to avoid unnecessary complexity in the manufacturing of mold for plastic.


2. Structural design of mold for plastic

A good set of molds requires not only good processing equipment and skilled mold makers, but also good structure design of mold for plastic, especially for molds with complex structure. The quality of mold design accounts for more than 80% of the mold quality.

A good mold design engineer needs to reduce processing costs and reduce the difficulty and time of the manufacturing of mold for plastic under the premise of meeting customer requirements.


3. Determine the material of mold for plastic and standard parts

In addition to considering the accuracy and quality of the product, the selection of the plastic die mold should also be combined with the processing equipment of the mold factory and the actual heat treatment capabilities so as to make an appropriate choice. In addition, in order to shorten the manufacturing cycle of mold for plastic, standard parts can be selected for processing as far as possible.


4. Processing and assembly of parts of mold for plastic

In addition to the reasonable mold structure and tolerance range, the processing of mold parts and mold assembly are crucial to the accuracy of mold for plastic. Therefore, mold processing accuracy and the selection of processing method play an important role in the manufacturing of mold for plastic.


5. Trial of mold for plastic

Mold trial is an important step to check whether the mold for plastic is qualified and to select the molding technology. It can verify the smoothness of demolding, how the cooling effect is, and the influence of sprue size, position, and shape on the accuracy and appearance of the product.
