We have modern and C.N.C. machines and other specially designed automatics each with its own specialised application.
Our Quality Control and Inspection Department, equipped with the very latest electronic testing instruments, has the formal approval of many international manufacturers who insist on the finest available guaranteed components and all our commercial work is still subjected to our internal quality control with thorough checks on tolerances and surface finishes. |
