Injection Molding Process |

Injection Molding ProcessAdvancements injection molding presses in hydraulic process and servo robots were unveiled by Arburg GmbH at its annual Technology Days conference and technical exhibition in March at its headquarters in Lossburg, Germany. A number of "guest" firms also made presentations at the event. They unveiled in-mold labeling (IML) technology from a relatively unknown source and a new gas-assist technique that promises super-fast cycles. Arburg also showed a new all-servo version of its Multilift V robot that can move at speeds up to 4000 mm/sec on its main axis. The air-cooled robot can handle payloads from 22 to 44 lb and is said to require less overhead space than competing models. New take on gas-assist The 370 is now the largest model The system was developed jointly by Huf Tools GmbH, Maximator GmbH, and also Linde AG. Maximator developed the special gas-flow switchover device and valve-gate nozzle. Linde supplies nitrogen gas and a full range of GIM-Cool technical services. The overflow-well concept is licensed from Gain Technologies. Huf Tools built the mold and is using GIM-Cool itself to produce door handles for the Ford Focus car. The 30% glass-filled nylon handles weigh 165 g. In a four-cavity tool, GIM-Cool reduced overall cycle time to 32 sec from 68 sec with standard single-nozzle gas assist. It even beat the 42-sec cycle obtained with water injection, says Michael Lehmann, technical director. Huf Tools is building GIM-Cool molds for Ford Focus door handles for molders in Poland, Spain, Wisconsin and Tennessee.
