The 48IMA15 GROUP was founded in 1999. The companies of the Group are: COECA Compañía Elaboradora de Caucho S.A., TECNASA, Tecnologías Aerospaciales S.A., SITEC Silicone Technology S.A.


COECA and TECNASA design and manufacture rubber and silicone parts by means of injection and compression processes, although the main business activity of SITEC is the formulation of silicone compounds.

COECA is a supplier for sectors as food, defence, railway, naval, construction or metallurgy between others. TECNASA has become established into the aeronautical and aerospace market, pharmacy, and laboratory equipment.

The closed cooperative and integration relationship existing between COECA, TECNASA and SITEC gives us the ability to cover business environments unattainable in any other way. One of the main advantages of the 48IMA15 Group is the ability to have three companies available that, even being independent one from each other, they get reinforced together sharing their know-how.

The 48IMA15 Group supplies products to leading companies in their respective markets. This is the case of Martin-Baker Aircraft, worldwide leading market manufacturer of ejecting seats for fighter planes; Diehl Remscheid, pioneer company in the production of track systems for tanks; as well as the main worldwide manufacturers of pressure cookers like Fissler, Kuhn-Rikon, Fagor, Brk or Magefesa. The high satisfaction of our customers encourages us to constantly outdo ourselves, improving our processes and developing new production and control systems.
