FAKUMA 2018: Patented quick-change mechanism


Quality Engineering is very important to Braunform. The company aims to provide maximum value in the field of mold making technology. The focus is on production efficiency and reducing the total cost of ownership for the customer - and this depending on the requested application. 

At this year's FAKUMA (the international trade fair for plastics processing from 16th to 20th October 2018 in Friedrichshafen/Germany) Braunform GmbH with partners will be presenting its patented quick-change mechanism mold technology. This mold principle is especially interesting for companies that steadily produce similar articles in small quantities or that have products with a high variety of variants. Another advantage is that changing the inserts is done fully automatically and thus the set-up times / costs are low. 

An example of this mold principle can be found on the booth of Engel in hall A5. On an Engel injection machine e-motion 330 / 120TL (fully electric) incl. automation, two geometrically different articles are manufactured in one mold base. These two articles build - when assembled – a caliper as the end product. The special feature of the two articles are the very different shot weights of the two articles, with one of the two articles additionally requiring a slider. 

With the quick-change mechanism a change of the floating inserts ejector side/nozzle side is carried out via robot, whereby the cooling is blown out before the inserts are changed. To ensure that the injection molding machine always knows which inserts are currently mounted in the mold base the inserts are coded. Depending on the installed application version, an injection molding machine could vary the process via sensors from Kistler. A robot removes the produced parts and assembles the two articles. The parts can still be individualized via a laser. An ABS is processed with a cycle time of approx. 20 sec.
