Production optimization


Our customers pay increasing attention to the price pressure generated by the market, while we are constantly obliged to seek solutions that reduce production costs. Our team of engineers responsible for implementing and optimising the production processes, together with our customers design solutions to eliminate changeover times to maximise machine uptime. An important aspect of these activities is optimising the fasteners and programmes for the CNC machine tools.

By participating in trade fairs and external training, we help to continually grow our knowledge levels. We focus on optimisation, on matching the production technology to the size and frequency of the production batches, and on shortening the material flow times within the company.

CNC machine


In our attempt to meet the expectations of our partners, in addition to a series of various bending machines, our own tool-room and 20 years of experience in profile bending, we have supplemented our offer with aluminium profile ageing and ageing details after bending. If we are dealing with difficult aluminium bending, these are often T4 profiles that are the source material for bending (naturally aged). They lack full mechanical strength and it is then necessary to harden profiles (age them) to T6.

Copal is one of the few companies that has its own ageing furnace that supplements our offer in bending aluminium profiles.
