We are an engineering company that deals with complete engineering production.

Material separation, welding, drilling and thread cutting, sheet metal processing (cutting, bending), CNC machining, surface treatment.

Steel and stainless steel covers, machine parts, structures and parts according to customer requirements are our product.

First-class quality, professional approach, price, delivery date and all agreed conditions are important to us, which is also confirmed by the ISO 9001 certificate.

We started working four years ago and we are gradually expanding our business and acquiring machines for a wider service. Our main goal is for the pieces to be precise and to be finished as soon as possible. We also have the necessary experience to work and what is equally important in mechanical engineering is understanding the drawings. We also respect the deadlines for making the piece because it is one of the important things to look at.

Grewe-Metalltechnik has existed as an owner-managed company since 2009.

We are a competent contract manufacturing company in the field of milling, sawing, drilling and sheet metal processing.

We offer solutions for all industries, from individual one-off production to medium-sized series production.
Our customer portfolio currently includes customers from the areas of: mold making, hydroforming, heating technology, filter technology, clean room technology, suspension technology and stand construction.

The core competence around zinc was and remains the focus of Grillo-Werke AG. Zinc metallurgy and sulfur chemistry belong together from the origin, but the two elements zinc and sulfur are the essential components of the parent ores. So there is still a natural context in current production.

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
development work

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.
