Tempering and Annealing

The applications of ESKA products in automotive industry make generally high demands on material strength. One could think here e.g. of transmission and engine parts or chassis components. Faulty strengths may give rise to partially dramatic consequences.

ESKA is specialized in the manufacture of high-strength connecting elements and forming parts. Heat treatment of products to obtain specific strengths figures among the capabilities of our company.

The manufactured products are exclusively heat-treated on three in-house tempering and annealing lines. A fully-automatic internal handling system maintains single-variety from the forming process via tempering and annealing up to the finished product. All heat treatment parameters are pointedly supervised and logged.

So, ESKA is able to offer self-made products of high strength in strength categories of 8.8 to 12.9 and/or products of special strengths.
