Collect and design the parts design, forming process, forming equipment, machining and special processing materials for the design of moulds. 

1., digest plastic parts drawings, to understand the use of parts, analysis of plastic parts of the process, size, precision and other technical requirements.

2., digestion process data, analysis of the process task book proposed molding method, equipment type, material specifications, mold structure type requirements are appropriate, can implement?. 

3. determine the molding method - direct pressure, casting or injection?

4, select molding equipment 
Mold according to the type of molding equipment, therefore, must be familiar with all kinds of molding equipment performance, specifications, characteristics. To estimate the shape and size of the die, determine whether the mold can be installed and used on the selected injection machine. 

5. specific structure scheme
(1) determine the mold type
Such as pressing dies (open type, half closed type, closed type), casting die, injection mold, etc.. 

(2) determine the main structure of the mold type
The ideal choice is to determine the structure of die cavity molding equipment required, the ideal number, can make the mold itself work to meet the technology and economy of the production of plastic parts required in absolutely reliable conditions.
