• Precision is put into practice: Welcome to Alhorn!

  • We produce injection-moulded parts from 0.1 g to full assemblied modules and proceed all technical thermoplastics, also with up to 60 percent glass fibre.

  • We construct sophisticated forms with the smallest tolerances and the highest quality.

  • Injection Moulding

  • Injection moulded components and modules

  • Tool manufacture and form construction

construction - tool making - injection moulding by Alhorn!

Our team of 190 highly qualified employees manufactures plastic injection moulds and injection moulded products for complex, high-precision technical products. For decades, the name Alhorn has stood for precision tools for connectors and complex components in the automotive, electronics and electrical engineering sectors. We set the bar very high for precision and produce perfect components with tolerances in the range of +/- 0.01 mm. We can use all technical thermoplastics, even with a glass fibre content of up to 60 per cent. Our high-cavity tools can be realized up to a size of 800 x 1,000 mm. Our injection moulding machines are all-electric or hybrid.


Experiences create solutions. We provide constructive solutions for your ideas. The most modern CAD/CAM workstations and industry-experienced engineers. There are many ways to get from the initial brief to the finished product. It is good to be able to depend on a single partner, who knows what it takes. For example, with a realistic simulation of future production.


In addition to the assembly of complete assemblies, we also produce in fully automated production lines.


Our plastic laboratory is a unique feature: During the incoming inspection, upon each initial sampling and at the start of each production, we perform chemical analyses. We also determine the solvent viscosity of plastic granules and components, so that we can ensure that the shot weight always fits the screw diameter of the respective injection moulding machine. This makes it possible to prevent excessive holding times and molecular degradation of the material from the beginning.

new building alhorn

The groundbreaking ceremony for the new production hall in Lübbecke was taken. Right next to the logistics center is being built on 2,500 m² a new hall for injection moulding which is completed in summer 2016.
