To effectively respond to your needs, ETMA has at your disposal a section for the manufacture of tools and equipments. We develop the tools that will be used in the manufacture of your parts, as well as assembly, inspection and sorting equipments, among others.

We manufacture precision turning parts to suit your needs, with diameters between 3mm and 42 mm. We also have machining centres that allow the execution of auxiliary processes.

We manufacture from metal strip stamped parts up to 3mm thick and 400mm wide. The production capacity of ETMA is ensured by the diversity and experience of over 75 years in stamping processes.

We work with progressive tools, deep drawing, Bihler forming machines, precision quick presses.

For the manufacture of metal parts, screws and rivets, ETMA has the capacity to work wires with a diameter between 1.5mm and 12mm in double blow and multi slide horizontal presses and in a variety of materials. We can finish the forged parts in secondary operations by turning, transfer turning and milling in pallet changing centres.

ETMA complements its range of transformation processes with new CNC machines for the three-dimensional forming of wire and tube, with the ability to form diameters between 2mm and 16mm. We have systems and accessories which allow finishing the parts with bevelling, re-rounding, drilling, threading, stamping and welding operations in order to finish the formed parts.

In order to improve the mechanical properties of the parts, ETMA performs heat treatments with core and superficial hardening – tempering, carburizing, carbonitriding – and heat treatments with release of tension and hardness correction – tempering, annealing. All treatments are carried out in a controlled atmosphere, thereby ensuring a class of resistance up to 12.9 and high superficial hardness.

In order to increase the corrosion resistance of the parts, the conductivity or to improve the appearance, ETMA is capable of performing the following surface treatments: electrolytics with deposition of Zinc, Zinc-Nickel, Nickel, Copper, Silver, Tin; chemicals for phosphatising and oxidation; dipping / spin: Zinc flake coating, top coats and sealants; dehydrogenation: performed in all parts of medium and high carbon; degreasing / wash: in closed chamber with perchloroethylene fulfilling European standards; deburring / polishing with abrasives: ceramic and porcelain

We offer a wide range of solutions for assembly/riveting/crimping and welding of components. Welding: resistance welding, spot welding, brazing and mechanical fastening systems (riveting). Assembly: manual assembly, assembly on transfer machines, robotic assemblies.

In order to keep up with the needs of the market, ETMA has a department with equipment for universal and/or custom made automatic inspection, for full control, according to the client’s control and inspection plan.
