The current production line of LITMAT S.p.A. consists of more than 1000 different plugs; this huge quantity of items, including semi-finished and uncoated parts, is stored in a single, computer controlled, mobile shelving system on rails.

These facilities, together with uncompromised quality and precise service give LITMAT S.p.A. the possibility to satisfy even the most demanding of its clients, as asserted by many important customers that rely on our products since several scores of years.

Plugs are made by different, all-in-house processes, depending on material, geometry and quantity; large lots of steel plugs are cold formed on horizontal presses, while very small batches are turned on single spindle automatic lathes or NC lathes for more complex shapes. We have the right technology for every plug.



Quality of products and services has always been considered by LITMAT S.p.A. as an indispensable prerequisite and a primary competitive factor with respect to its national and international competitors.

Since many years now, its quality organisation has been certified according to the main reference standards (UNI/EN/ISO 9001:2000 and ISO/TS 16949:2002); these results are not considered as a stand alone achievement, but as the evidence of a continuous effort to improve every aspect of its industrial processes as well as client satisfaction

Product quality is also guaranteed by LITMAT S.p.A. by means of the widespread application of Statistical Process Control, systematically performed on each machining operation with the aid of specific software and an integrated network of PCs.

A very efficient Quality Assurance structure, directly under control of the top management, gives strength and rigour to the application of internal quality procedures and drives effectively the continuous improvement process.
