Common issues during the trial molding process include stretching. So, how can we prevent stretching from occurring?

Material

Special materials with specific requirements undergo special treatments, such as phosphating, powder coating, and other methods. This is to create a film on the mold surface to prevent or reduce the issue of stretching. This method is highly effective, but it's quite costly, so it's not used frequently.

Material Structure

The cost of using a protective coating on the surface of the product is high, so we have replaced it with plastic film, applying a layer.PVCCoating with thin films is also a viable method. For smaller items, lubricants can be used to address the issue.

However, this method of producing films is only suitable for large products in small batch production, as each product requires the film, which significantly increases the time and waste.

Mold Structure

Here's the translated news content: When it comes to this point, it's worth mentioning that the previous methods can be said to have only partially addressed the issue. A better approach is to immediately alter the material and hardness of the mold's male and female molds if there's a problem with stretching, or to apply titanium plating and polishing to the product.

Achieving a fundamental change in the contact surface between the product material and the mold to eliminate the issue of stretching is a good and cost-effective solution.
