Thermal insulation plates are very important components for stabilizing the temperature of the mold or injection molding and for realizing energy savings for temperature maintenance. These are used as mandatory components in the injection molding of engineering plastics or super engineering plastics.
At Misumi, we offer thermal insulation plates as a product line up from which you can select the plate to suit your application.

In general, the methods of using thermal insulation plates are the following two.

1.When using by fixing to the platen of the injection molding machine.
2.When using by fixing at the back of the mold mounting plate

The following items are the criteria for selecting thermal insulation plates.

1. Heat resistance temperature

As a guideline, the following recommended usage temperatures can be used.

-Recommended usage temperature of 100°C or less
-Recommended usage temperature of 180°C or less
-Recommended usage temperature of 220°C or less
-Recommended usage temperature of 400°C or less
-Recommended usage temperature of 500°C or less

2. Material

The material is related to the recommended usage temperature and the strength of compression.

The following are the types of materials used.

-Cotton cloth + phenol plastic (Bakelite)
-Craft paper + phenol plastic (Bakelite)
-Glass fiber + silicate powder
-Glass fiber + ultra heat resistant epoxy resin
-Glass fiber + phosphate powder
-Glass fiber + borate powder

Asbestos is not handled in Misumi because it is considered to be a human health hazard.
