Teletronics: Consistent process integration boosts competitive abilityIn the teletronics industry, the subject of process integration often revolves around plastic/metal hybrid composite components. With the production of thermal switch housings at the NPE, ENGEL proves that it can also forge tailored solutions for this challenge. From the punching of the contacts to the inspection and labeling of ready-to-use electronic components, all work steps are fully automatic. The raw material for the brass carrier plates is fed directly from a reel and prepunched including a thread. The thread is servo-electrically tapped before the carrier plates – still on the line – are overmolded with glass-filled nylon on an ENGEL insert 60V/35 vertical injection molding machine. Quality control happens within the production process. In addition to the camera inspection, high-voltage testing is integrated into the tool, thus already guaranteeing a one hundred percent short-circuit inspection during production. In order to ensure seamless traceability, the good quality parts are labeled by laser before the sprue and carrier tabs are removed and the components are separated from the belt. Eight ready to install parts leave the production cell every 20 seconds.
This production solution, developed by ENGEL in cooperation with its partner MMS Modular Molding Systems (Austria), guarantees the lowest possible cost per unit while also achieving a high degree of flexibility. Thanks to the modular design of the MMS systems, additional processing units can be integrated, for example, for resistance testing or laser welding, riveting, assembly or cleaning of the parts. "Regardless of the number of modules, the entire process can be monitored and regulated via the CC300 control of the insert machine", says Stefan Aberl, director automation at ENGEL North America. "This substantially reduces complexity and significantly simplifies the operation of the entire process."
