Continuous Improvement Philosophy for over 35 years
Our core commitment is continuous process refinement and developing optimal solutions for every technical challenge. Our primary goal is to deliver the best customer experience for rubber composite parts.
Our Competitive Differentiation
We position ourselves as the premier supplier with the best customer experience for rubber composite parts. We distinguish ourselves through technical expertise, continuous improvement and custom solutions beyond conventional capabilities.
Our Technologies
We cover the entire process chain from toolmaking to post-processing. This enables faster production, greater technical refinement, and high reliability.
CNC milling and EDM
Tool manufacturing for rubber production and metal inserts in all quantities.
Injection molding
Series production of rubber and plastic parts with high repeatability. This method is particularly efficient for medium and large batch sizes.
Transfer molding
Ideal for medium to large series, intricate geometries, and the production of rubber-metal or other composite parts.
Compression molding
Best suited for small to medium series. Ideal for components with lower quantities, higher wall thickness, and composite material requirements.
Post processing
Comprehensive post-processing for flawless components, such as cryogenic deflashing, post-curing, etc.: burr free surfaces, enhanced material properties, and improved durability.
Our History
Elastomer specialists since 1990 – and always in motion.
