The Importance of Design Engineering in Plastic Injection Molding

The role of the Design Engineer is critical in this process. They assess the part design and make modifications and recommendations based on key product requirements including product usage and function. The engineer will need to know:

1. How will the part be used? Is it a standalone product or a component of a larger assembly?

2.What are the dimensional and tensile requirements?

3. Does the part need to withstand elements, pressure, chemicals?

A plastic injection mold design is built with these criteria in mind. Mold cavities, vents and gate placement will vary based not only on the part design but the type of resin as well. Taking all of these manufacturing factors into account is a challenging task and one that requires a strong knowledge base, not only of mold design but the injection molding process as well.

Why the lamp shell is plastic?

Why the lamp shell is plastic?

We have rich experience in manufacturing Automobile Structure Mould,plastic injection mold.I will always share some knowledge with you, welcome to follow me and give me some suggestion.

There are many reasons.

A. The elasticity of plastic is stronger than that of glass. Not in the case of severe impact will not be easily broken, even if it breaks down on the road, it will not cause great harm to pedestrians or animals.

B. Light quality, compared to the glass lamp housing, the plastic lamp housing is lighter about 0.3~1.4 kg

With the advantages of good corrosion resistance, good impact resistance, high transparency, good insulation, low thermal conductivity, good mechanical performance, strong plasticity, easy molding and processing.
