Thermoplastics

Thermoplastic Injection Moulding Manufactured in Switzerland


Thermoplastics can be processed using heat and precisely shaped through injection moulding. Silac manufactures plastic components using single-component injection moulding (1K) and two-component injection moulding (2K). This enables solutions for a wide range of applications, from packaging and closures to technical plastic components.

Silac processes thermoplastics into custom products in a variety of shapes, colors, and material properties. Depending on the requirements, the company produces hard, flexible, transparent, colored, or reusable solutions.

Thermoplastic parts with a clear function are in particularly high demand: hinges, seals, dispensing solutions, reusable products, or packaging components that function reliably in everyday use.

Local Production


Silac manufactures thermoplastic parts in Euthal using 27 injection molding machines with clamping forces ranging from 50 to 230 metric tons. The design, tooling, production, finishing, assembly, and logistics departments work closely together. This allows technical issues to be resolved early on and adjustments to be coordinated directly in-house.

This means:
