Structural design principles for product development:

1. Structural design should be reasonable, assembly should be reasonable, all plug-in structure should have clearance, to ensure enough strength and stiffness. And properly designed reasonable safety factor.

2. The structural design of plastic parts should consider the manufacturability of molds and simplify the manufacturing of molds as far as possible.

3. The structure of plastic parts should consider the plasticity, that is, the injection molding production efficiency of parts should be high, and the waste rate of injection molding should be reduced as far as possible.

4. Consider simple assembly production.

5. Standard and mature structures should be adopted for plastic construction as far as possible. So called template design.

6. Can be general/ordinary, try to use existing parts, do not open new mold.

7.Consider costs.
