In stamping, flat-lying insulation materials (Hostaphan, Mylar, Nomex, nonwovens, and others) are processed into stamped parts using stamping machines and custom stamping tools according to customer specifications. The stamping tools can optionally also bend in addition to stamping.
This means that during the stamping process, fold lines are simultaneously pre-embossed to facilitate later bending of the parts into their final position.
Steel rule cutting
A cost-effective approach is the stamping process using steel rule cutting. Steel rule dies consist of plywood boards with precisely cut slots, created by scroll saws or laser cutting. High-quality metal blades are inserted into these slots to serve as cutting edges.
Solid steel tools
On our automatic stamping machines, we also use solid steel tools. For customers with the highest demands on tolerance, dimensional accuracy, and tool life, this is the best alternative to steel rule cutting.
Experience and flexibility
Through our wealth of experience, we have continuously optimized our high-performance automatic machines and developed proprietary manufacturing methods that allow us to respond quickly and flexibly to individual customer requirements.
Depending on assessment or material properties, stamping is performed either from the roll or from pre-cut formats on state-of-the-art stamping machines. Production allows for a material thickness of stamped parts between 0.023 and 3.0 mm. The maximum dimensions of stamped and bent parts can be up to 1,000 x 2,000 mm.
Forming: our precision fitting
At GOBA, insulation materials are processed into insulation parts. Professional specialized tools are used for this purpose. Our know-how lies in forming insulation materials optimally without damaging the surface and structure of the material. The goal of forming is to achieve an optimal fit for the customer application.
In the electric motor sector, our insulation parts are fitted into your lamination stack. This ensures a smooth and efficient installation of our parts in your assembly process.
For special insulation parts with complex geometries, we form under the influence of heat.
Delivery forms and further processing
GOBA also delivers insulation parts stacked or packaged. This ensures automated further processing at the customer site. Package sizes and outer packaging can be individually designed. In selected customer projects, marker lines are applied to the insulation parts. The installation of the insulation parts can thus be detected and positioned by the customer using sensor technology.
