Gear Boxes Components

Gear change forks, levers, mounting plates, washers, kinematics assemblies: an extended range of high complexity products supplied directly to the car makers, to be assembled in their gear boxes, are the representative components of this product group.

Main processes.

We manage the complete value chain, from the raw material to the finished product, through a high level in-house process verticalization
Fine blanking

With 20 presses ranging from 220 to 800 ton, Gammastamp is the ideal partner to develop and blank parts requiring a superior stamping technology allowing for very high precision and low tolerances. We process steel and stainless steel raw materials in thickness up to 10 mm.

Transfer Stamping

Transfer stamping is a metal sheet forming technology based upon a press operating a number of dies as a complete system. The movement of the metal piece from one operation to the next one is performed by a transfer automation. Our 15 presses ranging from 100 to 800 tons are the ideal answer to customers requiring the flexibility offered by this technology to stamp parts with complex geometry and shape.

Machining, Welding

In a market more and more demanding in terms of design complexity and product requirements, machining and welding are complementary processes available at Gammastamp.

Chromium Plating

Beyond a shadow of a doubt, Gammastamp is market leader and reference in the manufacturing of buckle tongues. Our fully verticalized process includes the chromium plating phase. Every year one car out of ten produced around the world can be equipped with our tounges.

Deburring and grinding

The removal of the burrs generated during the stamping and the blanking processes is also made in house, by mean of both linear grinding and barrel deburring machines.

EOL (End-of-Line) Automatic Sorting

When we talk about quality, no compromises are accepted. To ensure our products can meet the extremely high level of customer requirements, a completely automated EOL sorting machine can be integral part of our manufacturing process.

Progressive Stamping

Progressive stamping is a technology that can incorporate cutting, punching, bending, coining, and several other ways of modifying metal raw material. A park of more than 30 presses, from 100 to 1200 ton, enables us to stamp steel in width up to 600 mm and 6 mm of thickness.

Injection Molding and Overmoulding

Plastic molding and metal overmolding are totally mastered in house technologies offered to our customers, either to manufacture plastic components used in more complex assemblies or to complete the added value of the product itself. We have more than 50 injection machines ranging from 80 to 400 tons, both horizontal and vertical presses, operated with manual or automated loading/downloading systems.

Hardening and Carbonitriding

The thermal treatment is part of our in house integrated processes. We have eight furnaces, both in salt quencing and oil quencing, allowing to treat up to 12.000 tons / year.

Tooling construction and maintenance

Tooling is the fundamental element in the stamping process. With a unique tooling shop equipped with all the technologies and the machines required for tooling construction, we can design, machine and build in house our dies and molds as well as perform production tooling maintenance.

Assembly

Gammastamp operate manual, semi-automatic and fully automatic lines for the assembly process of finished products. We have more than 30 specific dedicated assembly lines.
