Five Steps in the Injection Mold Production Process

2024-07-31

1. Process analysis of plastic products

Before designing the mold, the designer should fully analyze and study whether the plastic product conforms to the principle of injection molding processing, and need to carefully negotiate with the designer of the product to reach a consensus. This includes necessary discussions on the geometric shape, dimensional accuracy and appearance requirements of the product, and trying to avoid unnecessary complexity in mold manufacturing.

2. Mold structure design.

A high-quality mold not only requires good processing equipment and skilled mold manufacturing workers but also a very important factor is good mold design. Especially for complex molds, the quality of mold design accounts for more than 80% of the mold quality. An excellent mold design is: under the premise of meeting the customer's requirements, the processing cost is low, the processing difficulty is small, and the processing time is short.

3. Determine the mold material and select standard parts

When selecting mold materials, in addition to considering the accuracy and quality of the product, the actual processing and heat treatment capabilities of the mold factory should be considered to make the right choice. In addition, to shorten the manufacturing cycle, existing standard parts should be used as much as possible.

4. Parts processing and mold assembly.

In addition to giving the best structure and reasonable tolerance matching during design, the accuracy of the mold, parts processing and mold assembly is crucial. Therefore, the choice of processing accuracy and processing methods occupies a dominant position in mold manufacturing.

5. Mold trial

From design to assembly, a set of molds only completes 70% to 80% of the entire manufacturing process. The error caused by the inconsistency between the expected shrinkage and the actual shrinkage, the smoothness of demolding, the cooling effect, and especially the influence of the size, position, and shape of the gate on the precision and appearance of the product must be tested through mold trial. Therefore, mold trial is an indispensable step to test whether the mold is qualified and to select the best molding process.

In addition to mold design and manufacturing, our company can also provide Aero injection moulding, automatic injection molding, and medical device injection molding.
