Consultation
From Idea to Finished Component:
With extensive expertise, we support you in material selection, design optimization, and feasibility analysis to ensure your projects are implemented efficiently and successfully.
To optimize product quality, we offer initial sample testing under series production conditions (VDA/PPAP) or development sampling to evaluate planned properties.
Additional tools include sampling series with different materials or rapid tooling. Our many years of experience are incorporated into every tool design before and during the sampling process, resulting in a well-balanced interplay of geometry, material, and process.
Tool making
The Tool as the Basis for Optimal Performance:
A precise and well-developed vulcanization tool is essential for efficient and high-quality production.
Our tool manufacturing is carried out in close collaboration with experienced partners to ensure the highest precision and flexibility in both production and maintenance.
We handle the entire design process and advise you on suitable manufacturing options. The tool functions like a custom-tailored suit for the component—individually designed to maximize efficiency, durability, and quality. This is typically based on technical drawings or 3D data of the component..
Manufacture
For over 50 years, we have been manufacturing at our site in Köngen, utilizing state-of-the-art production processes to ensure the highest precision and quality. Whether single components or large series, we cover a wide range of applications and can tailor our production to meet specific customer requirements.
Any necessary pre-processing, such as for rubber-metal composite parts, is carried out in-house, allowing us to react quickly and flexibly.
Our machinery includes equipment from leading manufacturers such as DESMA, REPinjection, and Wickert, enabling us to ensure flexible and efficient production.
Our common manufacturing processes include:
Compression Molding Process
In this vulcanization method, a rubber blank, precisely matched to the part’s volume, is placed into the open mold and compressed under high pressure and heat. This process is particularly suitable for cost-effective production of small quantities.
Transfer Molding Process
This method is a hybrid between compression and injection molding. The injection process takes place within the mold itself by pressing the rubber blank into a transfer pot. The compound flows into the cavity through channels in the mold. Compared to injection molding, this method can reduce tooling costs and is also suitable for producing large-volume parts.
Injection Molding Process
In this process, the raw material is automatically fed, plasticized, and homogenized before being injected into the closed mold under high pressure. Since the molds are more complex and the machinery setup requires higher effort and longer setup times, this method is primarily used for larger production volumes. The injection into the already closed mold allows for minimal flash formation, ensuring tighter dimensional tolerances.
Choice of Materials
The complex requirements of modern components demand careful selection of the appropriate material.
Through collaboration with major compounders, we can offer a portfolio of several thousand standard and special formulations with a Shore hardness between 20° and 90° Shore A. This allows us to meet individual demands regarding mechanical properties and chemical behavior.
The following materials are used:
- Natural Rubber (NR)
- Nitrile Rubber (NBR)
- Ethylene Propylene Diene Rubbers (EPM/EPDM)
- Hydrogenated Nitrile Rubber (HNBR)
- Fluorocarbon Rubber (FKM/FPM/Viton®)
- Silicone (VMQ/HVT)
- Polychloroprene Rubber, Chloroprene Rubber (CR)
- Styrene-Butadiene Rubber (SBR)
See also the following list.
Our goal is to provide a tailored material solution with an optimal interplay of function, quality, and cost-effectiveness.
For composite parts in the metal and plastic sectors, we have an extensive network of qualified suppliers, offering you complete solutions from a single source. Our partners in turning and milling technology specialize in high-quality metal components, ensuring precision and reliability.
Quality
Quality is for us a dynamic and strategic sucess factor and therefore one of the most important tasks of all employees of our company. The customer with his wishes and goals is the focus of our business and defines the quality benchmarks. To document our quality standard we are since 2001 successfully certified in accordance with ISO 9001:2015.
Rework
To ensure optimal results, we offer a wide range of post-processing options.
Our services include a cryogenic deburring system for precise deburring at low temperatures, an industrial washing system for thorough cleaning, and manual post-processing for special requirements.
Additionally, we rely on continuous optical inspections for quality control, Shore hardness measurements to test material hardness, and mechanical deburring on lathes, specifically for rubber-metal components.
