Precision in perfection

Production of complex and technically highly precise injection moulded products and tools.

For more than 40 years, the name Alhorn has been synonymous with products in the field of toolmaking and injection moulding production. And when we say high-precision, we mean it:
we design on behalf of the customer producing perfect products with the lowest tolerances.

As part of the OKE Group of Companies, we support our customers in tool-specific and process-optimised item design. We cover the entire process chain from the conception of the injection moulding tool to the full integration of automation and assembly devices to the perfect turnkey solution for serial production.

  • Residual moisture analysis using Aquatrac
  • FTIR spectroscopy ATR method
  • Differential scanning calorimetry according to ISO 11357-1/-2/-3
  • Fibre analysis of long fibre-reinforced thermoplastics
  • … and customised analysis!
Using potential

Multi-component injection moulding

While 2K injection moulding is an established process for obtaining  ›ready-to-install‹ series parts from just one mould, we achieve further possibilities for integrating functions in a single component by combining three materials in one injection process.

Alhorn, for example, we produce high quantities of rail sliders for window lifters using an index plate mould. The materials used in this specific product example are a polyamide with a glass fibre content of 45 percent, a POM and a TPE-U. We would also be happy to determine your possibilities by using a third component!
