About Dreistegen
Dreistegen GmbH, based in Monschau, is a specialized surface technology service company. The company offers plasma nitriding, hard coatings using the PVD and CVD processes, DLC coatings based on its own Caveo process, as well as wear-resistant anti-adhesion coatings and polishing. A key focus is the finishing of large components: blown film and blow molding components can be coated with diameters up to 1,200 mm, and plastic injection molding screws up to a length of 4,500 mm. In addition to case hardening heat treatment and coating, plastics processing, aluminum die casting and metal forming are offered. The main customer industries are the plastics processing industry and the automotive sector. The company was founded in 2008, survived a major fire in 2023 that destroyed half of its treatment capacity, and restored its production capacity by 2024. Dreistegen has been certified to ISO 9001:2015 since 2020.

Materials & Processes
Plasma Nitriding
Case hardening heat treatment to increase the wear resistance of tools and long parts.
PVD Coating
Hard coating for blown film and blow molding components up to 1,200 mm diameter.
CVD Coating
Hard coating of long parts such as plastic screws up to 4,500 mm length.
Low-Temperature CVD
Interior coating of tools at low process temperatures.
DLC Coating (Caveo Process)
Coating of large metal forming tools for the automotive industry.
Anti-Adhesion Coating
Facilitates demolding, shortens color changes and reduces deposit build-up.
Polishing
Surface refinement to complement the coating processes.
Aluminum Die Casting
Production of lightweight, stable and dimensionally accurate components.
Plastics Processing
Manufacture of precision-fit plastic components with high design variety.
Metal Forming
Manufacture of robust components with precise geometries.
