Who we are
and what we do

company C.S.O. introduction

The history of CSO dates back to 1992 and the company is now a modernly equipped organisation for which the strict requirements of the customers are the Alpha and Omega of its operations. We have learned to perceive the problems arising from the most demanding requirements of the customers as a means to self-perfection in order to be a step ahead of the competition. We want to be the symbol of the quality and stability of ultra precision components for all industrial applications with a majority share of the aerospace industry. We are currently included in the database of approved suppliers of aviation components for the Airbus air management system, also mechanical avionic, water management and seat components.

Application of products

The company development copies the continuous development of society and the market

We started with the manufacture of ordinary steel components and gradually added stainless steel and tool steel. Several years ago, we fell in love with aluminium alloy products, whose production is currently more than half the volume of our products. The events of recent years inspired us to get established in the field of high-precision parts made of exotic materials – for instance, Titanium or Inconel.
