Before the mold design, the designer should fully analyze and study whether the plastic products comply with the injection molding processing principle. It is necessary to carefully negotiate with the product designer and reach a consensus. It includes the necessary discussion on the geometry, dimensional accuracy and appearance requirements of products, so as to avoid unnecessary complexity in mold manufacturing as far as possible.

2、 Mold structure design.

A set of high-quality molds not only needs good processing equipment and skilled mold manufacturing workers, but also a very important factor is to have 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 to make the processing cost low, the processing difficulty small and the processing time short on the premise of meeting the requirements of customers.

To achieve this, we should not only fully digest the requirements of customers, but also understand the injection molding machine, mold structure, processing technology and the processing capacity of the mold factory. Therefore, to improve the mold design level, the following points should be achieved:

1. Understand every detail of each set of mold design and the purpose of each part in the mold.

2. In the design, refer to the previous similar design, understand the situation in its mold processing and product production, and learn the experience and lessons.

3. Learn more about the working process of injection molding machine to deepen the relationship between mold and injection molding machine.

4. Go to the factory to understand the process of processed products and understand the characteristics and limitations of each processing.

5. Understand the mold test results and mold modification of the mold designed by yourself, and learn lessons.

6. Try to use the previously successful die structure in the design.

7. Learn more about the impact of mold water on products.

8. Study some special die structures and understand the latest die technology.
