What are the processes for making plastic molds?

The core process of making plastic molds includes the following steps:

Determine the design goal: First, it is necessary to clarify the purpose and requirements of mold design, such as producing a specific type of plastic products, meeting production requirements, and meeting specific cost and delivery time requirements.

Product analysis and structural design: Detailed analysis and structural design of the plastic products to be produced, study the shape, size, structural characteristics, material requirements, etc. of the plastic products, and design the mold structure accordingly.

Select suitable materials: According to the results of product analysis and structural design, select suitable mold materials, considering factors such as material processing performance, wear resistance, and corrosion resistance.

Overall mold design: Including determining the overall structure of the mold, the design of each component, the closing height of the mold, the size and layout of the template, etc.

Gating system design: Determine the shape, position and number of the gate, as well as the design of the runner, which directly affects the quality of the injection molded product.

Cooling system design: Consider the heating and cooling effects of the mold, as well as the convenience of manufacturing and maintenance.

‌Exhaust system design‌: Determine the position and size of the exhaust groove to remove air and volatiles in the mold to prevent pores and deformation of the product‌.

‌Electrode, ejection system and guide system design‌: Design the electrode and ejection system according to the size and shape of the product to ensure the stability and accuracy of the mold opening and closing process‌.

‌Control system design‌: Control the temperature, pressure and other parameters of the mold, and consider the structure and accuracy of the control system‌.

Maintenance design‌: Consider the mold maintenance method and maintenance plan to ensure the service life and stability of the mold‌.

Complete detail processing‌: Mark the dimensions, write technical requirements, etc., to ensure that all details of the mold design are properly handled‌.

‌In the specific operation process, the following points should also be noted‌:

When starting the mold design, multiple options should be considered, the advantages and disadvantages of each option should be weighed, and the best option should be selected from them‌.

During the design process, more reference should be made to similar drawings designed in the past to learn from experience and lessons‌.

After the design is completed, it is necessary to conduct multiple proofreading and review to ensure the accuracy and feasibility of the design‌. In actual production, it is necessary to communicate more with the factory, understand the processing and manufacturing conditions, constantly summarize experience, and improve the design level. Through the above steps and precautions, the smooth and efficient production of plastic molds can be ensured.
