The manufacture of complex tools, especially in the production if inserts, occurs in-house in close coordination between the manufacturing and quality control departments, all supported by the networked computer system. Partially and fully automated facilities are available for component assembly. Special emphasis is given to the ultrasonic welding and thermal embossing technologies, and to multi-colour printing on plastic parts using the Tampo-Print method. An integrated production quality control in the automated assembly facility is, of course, in use.
