From the idea
to series production.

Engineering, toolmaking and automated plastics production under one roof – based in Tröstau, family-run and focused on technical precision since 1969.

Precision is
our process.

For more than five decades, we have been developing and manufacturing injection moulding tools and technical plastic components. Short paths between engineering, toolmaking, injection moulding, inspection and assembly enable fast coordination and reliable series processes.

The company began in 1969 in the founder’s basement workshop. The first in-house injection moulding machine followed in 1972, the first 900 m² production hall in 1979 and a second hall of the same size in 1982. Today, modern manufacturing technology, skilled employees and certified processes are at the heart of our operations.

Everything under one roof

Two core capabilities.
One seamless process.

Plastics processing at Willi Geyer

Plastics processing

Automated. Flexible. Series-ready.

Technical thermoplastics are processed on 15 modern injection moulding machines in small, medium and high-volume series. Capabilities include insert-moulded parts, prototypes, samples, initial series, visible parts and in-house assembly.

  • Part weight0,1–400 g
  • Clamping force220–2500 kN
  • Tool weightup to 1,500 kg
  • QualityDIN EN ISO 9001:2015
Toolmaking at Willi Geyer

Toolmaking

Tools for technical plastic parts.

Design and CNC programming are carried out with VISI. In-house manufacturing includes CNC milling, sinker and wire EDM, grinding, laser welding and laser marking. Common CAD formats can be processed.

  • CAD/CAMVISI
  • Milling3+2 axes
  • Wire EDM≥ 3 µm accuracy
  • LaserMicro-machining

From concept to production readiness

Development with
seamless handovers.

01

Concept & Engineering

CAD data, component requirements and the manufacturing strategy are aligned from the outset.

02

3D-Prototyping

3D printing supports early samples, visualisation and handling fixtures.

03

Tool Manufacturing

Milling, EDM, grinding and laser processing form the complete in-house toolmaking chain.

04

Injection Moulding & Inspection

Direct sampling, optimisation, 3D measurement as well as pressure and tensile testing.

05

Series Production & Assembly

Automated production, gentle part removal and in-house assembly on request.

Quality & Sustainability

Measure, inspect,
improve.

To meet increasing industrial requirements, the company continuously invests in modern measuring and testing equipment, including a full 3D measurement system as well as pressure and tensile testing. Custom measuring fixtures can be manufactured in-house by our toolmaking team.

At the same time, we continue to expand our experience with plastics made from renewable raw materials and biodegradable materials; reducing our CO₂ footprint is an ongoing objective.
