Plastic Injection Moulding — Precision in Small and Medium Series

We process a wide range of engineering plastics, including PA (polyamide), PP (polypropylene), POM (polyoxymethylene), ABS, PC (polycarbonate), PE and many more. Material selection is made together with you based on the mechanical, thermal and chemical requirements of your component.

Injection moulding generally becomes economical from a quantity of approximately 500–1,000 parts, as the tool costs are spread across the parts. For smaller quantities, we offer prototype tools as a cost-effective entry solution. We are happy to advise you on the optimal manufacturing strategy.

Tool manufacturing takes between 4 and 12 weeks depending on complexity. Simple prototype tools can be realised in as little as 2–4 weeks. We create a concrete schedule for you after receiving the CAD data.

With our modern injection moulding machines and precision tools, we achieve tolerances according to DIN 16742. Standard tolerances are in the range of ±0.05 to ±0.2 mm, depending on component size, geometry and material. Tighter tolerances are possible by arrangement.

The cost of an injection mould varies greatly depending on complexity, number of cavities and tool steel. Simple single-cavity tools start in the low five-figure range, while complex multi-cavity tools can be significantly higher. We create a transparent quote for you after reviewing your component drawings.

Yes, we offer multi-component injection moulding (2K injection moulding) for components made of different materials or colours. This technology enables the combination of hard and soft components in one manufacturing step, saving assembly costs and increasing component quality.

We offer various surface qualities directly from the tool — from technical surfaces to high-gloss polishing. Additional post-processing such as printing, laser marking or assembly is also possible. The desired surface quality is already considered during tool design.

A prototype tool is made of softer steel, has a shorter tool life (approx. 1,000–10,000 shots) and is more cost-effective. It is ideal for sampling and small series. A series tool is made of hardened tool steel, has a tool life of 500,000+ shots and is designed for mass production.

Yes, our in-house tool making department handles the maintenance, repair and optimisation of existing injection moulds — even if they were not manufactured by us. Regular tool maintenance extends tool life and ensures consistent part quality.

Quality assurance is an integral part of our manufacturing process. We carry out initial sampling according to PPAP/VDA, monitor series production with statistical process control (SPC) and document all relevant parameters. On request, we create measurement reports and inspection reports for each batch.
