Aircraft engine components Unique production programme. The inputs rank among the hardly machinable alloys, but C.S.O. has already earned a lot of experience and intends to continue expanding its competences in this significant portfolio. Modern principles of management and monitoring of processes Achievement of excellent results in the issues of fulfilment of customer requirements particularly with regard to the quality of the products and services. Preforms for PET bottles Prior to the coming of the real PET bottles, it is first necessary to manufacture the so-called preform. Integrated management system for quality AS9100 The integrated management system for quality, environment, occupational safety and health is based on the rules of the ISO9100. and environment ISO14001 Composites Our mission is to produce superior carbon parts by merging C.S.O.´s rich hands-on machining experience together with Carbon division management´s long-standing know-how in the field of composites.

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.

In-house technologies


Components of non-rotary character made of various materials are made in C.S.O. spol. s r.o. 3-axis machining with process management by highly experienced experts at the level of programmers, fixers and operators. The newest CAM software versions that are subject to regular upgrade are a matter of course.
