Based on the production of insulated and rolled bars, Gindre has developed Maxiflex flexible bars, an innovative product made from highly flexible bare or tinned copper strips. Maxiflex are insulated with high-quality PVC, offering exceptional mechanical, electrical and self-extinguishing properties. Our in-depth technical knowledge ensures optimum flexibility, excellent value for money and first-rate quality.

Our semi-finished products in bars, coils and sheets are the result of two centuries of know-how in extrusion, drawing and rolling processes. These products are available in a variety of shapes (rectangular, square, round, hexagonal) and copper alloys to meet a wide range of technical requirements. An essential raw material for major energy projects, our copper is recognized for its benefits in terms of electrical, thermal and mechanical conduction.

From raw materials transformed by our extrusion, drawing and rolling processes, Gindre produces copper and copper alloy components, adapting to the most demanding technical constraints. Whether machining and turning, punching and bending, cutting or stamping, our technical teams develop new products in close collaboration with our customers. We also offer options for insulation, surface treatment and sub-assembly assembly. Combined with a customized logistics solution, we enable our customers to concentrate on their core business. 

CUSTOMIZED COPPER COMPONENTS

Whether companies wish to outsource production or are looking for ready-to-use components, Gindre's integrated industrial organization (from material to component) and all the technologies available in its various workshops in Europe and around the world guarantee :

• have parts perfectly adapted to their needs and technical requirements every time
• make savings on their supply chain by optimizing the use and sourcing of materials
• reduce inventory and red tape...

Based on specifications, design office teams define the material best suited to the need, and the basic profile is usually specially manufactured.

They develop and design the optimum processes and tooling to produce the required part, whether conventional or special. To achieve this, they combine technical know-how with traditional or state-of-the-art production resources, which are managed by experienced professionals.

The technologies available for copper and copper alloys include :

cutting, die-cutting, punching, bending, turning, tapping, CNC machining, sheet metal nibbling, waterjet cutting, brazing, cladding, surface treatment (silvering, tinning, nickel plating, gilding), epoxy, inserting, assembly, kitting...

Thanks to our factory in Germany, we give our customers access to a wider range of products. We manufacture near Düsseldorf using a multi-step process that combines drawing, rolling, and annealing to produce a wide range of flat and round wires in small sections. Typically custom-made to meet client specifications, our production capabilities also allow us to manufacture this range in various shapes (rectangular, square, round, hexagonal), different sections/dimensions, and with surface treatments such as silver plating or tinning. We support our clients in markets such as automotive, grounding, and electrical equipment.
