Thermoset for durable plastic parts


Thermosets are hard, dimensionally stable, and often glass-fiber-reinforced plastics. They are processed under pressure and heat, during which they undergo permanent cross-linking. Afterward, they remain dimensionally stable even at higher temperatures.

This makes thermosets particularly suitable for applications where mechanical stress, heat, electrical insulation, or chemical resistance are important factors. Typical applications include covers, housings, base plates, technical components, and parts for the electrical and mechanical engineering industries.

Silac has many years of experience in the development and production of thermoset solutions. The design, tooling, and production departments work closely together to ensure that the material, shape, and application are harmonized.

Thermoset Production with In-House Tooling


Thermosetting plastics place high demands on materials, tooling, and process control. Even during the development phase, it must be clear what loads the component is expected to withstand and how it will be manufactured later on.

This is where having our own toolmaking department pays off. Molds can be built with precision, customized, and maintained over the long term. This supports stable mass production and streamlines the workflow between design, toolmaking, and production.
