Eye-let High Hardness Locking Spring

Complex, tiny,irregular,high precious and high surface requirement parts are suitable for MIM process(Metal Injection Moulding).

Items of the main picture above are all made by our company Shangong No2 Machinery Co. We have aboundant experience and strong engineers to complete projects by our customer.

Here we introduce how to solve the extrude by the closing die because we meet this problem in doing these round steel lock spring.

Reasons: Because of high temperature and injection pressure, or inadequate clamping force.

Solutions:

1, Reduce injection pressure and solidification temperature of cylinders;

2, Shorten the injection time

3, Reduce the injection speed

4, Change to a high clamping force machine

5, Modify the clamping surface and clean the clamping surface

6. Use a low viscosity material.
