Can Injection Molds with Thermal Insulation Plates Use Magnetic Platens for SMED?

When it comes to optimizing efficiency in injection molding processes, quick mold changes are a crucial factor. One of the tools that can significantly streamline this process is the electro permanent magnetic quick mold change system, commonly known as a magnetic platen. However, many users often question whether these magnetic platens are compatible with injection molds that have thermal insulation plates.

Compatibility of Magnetic Platens with Injection Molds Featuring Thermal Insulation Plates

Yes, injection molds equipped with thermal insulation plates can indeed use magnetic platens for rapid mold changes. The key consideration here is the material and placement of the insulation plates.

Here’s How It Works

1. Thermal Insulation Plates and Magnetic Platens: Injection molds often come with thermal insulation plates to manage the temperature during the molding process. These insulation plates are typically made of non-magnetic materials, which might seem like a hindrance to using magnetic platens.

2. Solution: To effectively use a magnetic platen, you need to address the non-magnetic insulation plates. The solution involves removing these thermal insulation plates from the mold itself. Once removed, the insulation plates can be installed onto the backplate of the injection molding machine.

3. Revised Setup: With the insulation plates now attached to the machine’s backplate, the magnetic platen can then be used to securely fix the mold in place. This setup allows for the benefits of quick mold changes without compromising the functionality of the thermal insulation.

In Summary

Injection molds with thermal insulation plates are fully compatible with magnetic platens, provided that the insulation plates are relocated as described. This adjustment ensures that you can leverage the efficiency and convenience of magnetic platens while maintaining the thermal management required for optimal molding performance.
