Mold Tryouts and Optimizing the Injection Process

When finished the new molds, the mold tryout is essential step to verify the injection molds and find out any potential defects and solve it to ensure the mold perform stable and efficiency during molding production.

For every project, when we summit the samples, in the meantime, we always provide mold trial report, video of the injection process, injection machine setting parameters and dimension report etc. to our customers.

Here shares one case we just had mold trial recently, and the issues occurred and how we solve it.

Issue: General 4-cavities filling is balanced, but only one part has flash and three parts have damage issue at the cavity spring slider position.

• Flash issue-Solution: improving the fitting.

• Parts damage-Solution: The spring structure of the slider is not good, and it is easy to cause damage to the parts. We added the T-shaped guide block to avoid the part damage issue.
