Design Your Own Hot Knife

All of our Hot Knives are designed and constructed as modular systems which allow us to customize any machine quickly. We'll custom-design just for you from over 400 various combinations and configurations. See how we configure them here.

In addition to our hot knife cutters and spare parts, we can also offer components and assemblies for integrating into, or building your own, cutting equipment. These are broken into several general categories. Click the images below for more information.
