Goletz, the full-service provider for plastic components and assemblies.

As a medium-sized family business, Goletz GmbH has been the competent partner for the production, processing and finishing of plastic parts for industry for over 50 years. This is about more than injection molding. Comprehensive advice from the first product sketch to the finished product is the basis for innovative and qualitative solutions. For us as a team, competence in plastics means practical experience and a wide range of manufacturing and processing methods such as multi-component manufacturing, surface treatment or the assembly of complete assemblies.

We produce for you on the most modern, screen-controlled ARBURG machines.
We have experience in processing
any thermoplastics and thermoplastic elastomers.

The company Gottlob Dietz GmbH is a manufacturer of elastomeric parts, a chemical company. We have specialized since its foundation in 1976 to form high-quality technical rubber products such as membranes, PTFE laminated fabric reinforced parts and rubber-metal connections that we make in the pressing process. Another branch of production, the production of rubber and TPE parts were injection molded to it.

Gronbach has been developing and producing components and complex assemblies on a production area of over 20,000 m2 with 290 employees since 1964 and has also specialised in the processing of stainless steel and aluminium, surface finishing and plastic injection moulding. In addition, a separate department is dedicated to the development of new surface technologies, manufacturing and assembly processes.

The core competencies of the Wasserburg site are in the following areas:
Metal processing (bending, milling, deep drawing, drilling etc.)
Surfaces (anodising, powder coating, printing, laser engraving)
Plastics technology (hybrid, back-moulding)
hybrids
instrument engineering

PRODUCTION TECHNOLOGIES AND PROCESSES

In the area of production technologies, we have specialized primarily in the surface refinement of stainless steel and aluminum, the production of functional and visible components as well as plastic injection molding and adhesive technology. These technologies form the basis of our equipment technology, but are also offered by us as individual services.

We are constantly expanding and renewing our portfolio with new combinations of technologies and materials, e.g. in the art of back-moulding metals such as aluminium and stainless steel with different plastics, in order to be able to offer our customers high-quality and cost-optimised manufacturing processes.

Optimal solutions for mold making, model making, prototypes, pre-production, production, assembly

The Grunewald group of companies with offices in Grunewald (headquarters), Grunewald Tools & shapes, Grunewald cast and Grunewald & Partner Rapid Prototyping in Bocholt (D), Grunewald Tooling in Irxleben (D), Grunewald Stade (D) and Grunewald New Technologies GNT (USA ) forms a strategic alliance for toolmaking, mold and model making and the development, design and production of metal components, plastic components and fiber composite parts from the design, through prototyping and pre-production through to the methods of mass production.
Based on our extensive CAD capabilities, we offer the full range of modern techniques for the production of equipment and products. The efficient use of our diverse possibilities with a nearly 100% vertical integration offers compelling advantages in terms of reducing costs and time associated with a very high quality standard.
This results in a high level of satisfaction among our customers. 190 qualified engineers, skilled workers, students and trainees represent the future of our company safe.
