  • Connectors, terminals, and contact carriers
  • Insulation components with defined dielectric properties
  • Switch and push-button components using multi-component technology
  • Series parts with tight tolerances and high reproducibility

Materials and processes for electrical engineering

Electrical plastic components must do more than just look good: they protect sensitive electronics, provide reliable insulation, and withstand both thermal and mechanical stresses. At Schröder + Heidler, we select the right process and the optimal material for every requirement—whether glass fiber-reinforced polyamide, flame-retardant ABS, or high-temperature-resistant PBT.

  • Our automated production processes and continuous inline quality monitoring ensure consistently high results—component by component, series by series.

  • From engineering thermoplastics and flame-retardant compounds to high-performance plastics—we process the materials your application requires.

  • Through optimized tooling and processes, we maintain the tightest tolerances—critical for precise fit in electrical assemblies.

Application areas in electrical engineering

Our plastic components for electrical engineering are used across a wide range of applications—wherever precision and reliability are essential.
