High-Performance Plastics in Application

Our products are designed for environments where performance is critical. Precision components made from high-performance plastics, such as PPS, are intended for applications that must withstand heat, chemicals, pressure, and other extreme conditions. They stand out due to their unique material properties, including high-temperature resistance, chemical resistance, and electrical insulation, making them suitable for a wide range of applications.

In addition to our core markets of automotive, transportation, and electronics, which we have successfully served for more than 30 years, our precision components are also suitable for a broad variety of applications in the defense and industrial sectors.

Mobility – Core Market & Core Competence

For applications in passenger cars, commercial vehicles, agricultural machinery, as well as rail, marine, and aerospace transportation, we develop and manufacture components and product systems made from high-performance plastics for the entire drivetrain — from powertrain solutions for combustion engines to hybrid and electric motors, as well as innovative applications for fuel cell technologies.

Specific Product Examples

  • Oil and vacuum pumps
  • Water circulation and coolant pumps
  • Actuators, throttle and control valves, as well as variable valve timing systems for load control
  • Emission and thermal management systems (fluid management)
  • Solenoid valves (hydraulic, coolant and water valves, isolation valves)
  • Thermostat housings
  • Coolant and oil ducts / pump housings
  • Sensor housings (e.g. for MAP, MAF, and pressure sensors)
  • Connectors and plug connectors in high-voltage systems
  • High-voltage insulating components
  • Battery modules, cell holders, and frames (PEEK/PPS)
  • Inverter and power electronics housings (PEI, PPS)
  • Cable harness brackets and retainers
  • Airbag housings and gas generator components
  • Interior fastening elements requiring high flame resistance

Defense – Precision Under Extreme Conditions

For applications in the defense and security industry, we develop and manufacture highly specialized components and product systems made from high-performance plastics that ensure maximum reliability even under extreme operating conditions.

Specific Product Examples

  • Housings for communication and radar systems
  • Connectors, insulators, and PCB carriers made from LCP, PPS, or PEEK
  • Seals and precision plastic parts for navigation and control systems
  • Drone components (lightweight, thermally stable parts)
  • Fasteners / clips in avionics systems
  • Radomes and sensor covers (LCP, PPS – radar-transparent)
  • Lightweight structural components in drone frames (fiber-reinforced PEEK/PEKK parts)
  • Engine compartment components (PPS, PPA, PEEK due to heat and chemical resistance)
  • Electronics housings, sensor modules, and connectors
  • Pump and valve components (saltwater-resistant: PPS, PEEK)
  • Seals, technical guide elements, and sliding bearings

Industry – High Performance in Every Application

Engineering & Prototyping

Development, Product Design, and Engineering

Every project starts with an idea! We guarantee production-ready and cost-effective product development backed by innovation and expertise. To visualize new products and tools, we utilize state-of-the-art 3D CAD workstations and prototyping.

Innovative Hybrid Parts

Combining Plastic and Metal

Using state-of-the-art techniques, we are able to combine metal and plastic into an integrated assembly through insert molding. Our expertise includes the precise overmolding of delicate metal inserts (hybrid injection molding), such as connectors, shafts, and contacts.

PPS Champion

High-Performance Plastics as a Metal Substitute

We are experts in injection molding with the high-performance plastic PPS. Its unique properties and significant advantages place PPS at the top of the plastics hierarchy.
