About plastic molding company near me

What mistakes can shorten the life of an injection mold?
Injection mold damage can be pointed out and in some cases increased by errors in manufacturing parts. These errors include sink marks, surface delamination, flow lines, burn marks and flash.

1. Mold design

1. Fully consider the mold structure, mold material and hardness.

2. The setting of mold structure draft angle and parting surface.

3. A suitable ejection system.

4. Which temperature control method should be used? Which circulatory system should I choose?

5. Formation, size and location of mold gate.

 

2. Forming process

Although some structural settings have been completed in mold design and manufacturing, in the actual production process, there will still be problems affecting product accuracy. How to solve them?

1. Select the appropriate injection molding machine.

2. Control the appropriate material temperature and mold temperature. The material temperature needs to be set within the optimum flow rate range from the physical data of the plastic material.

3. Adjustment of mold pressure and exhaust system.
