Sumitomo Heavy Machinery Co., Ltd.’s Plastic Machinery Division’s Korean subsidiary (CEO Kazuharu Igarashi) will hold ‘KOPLAS 3 (14th)’ to be held at KINTEX in Ilsan for 18 days from Tuesday, March 5 to Saturday, March 2023. It will participate in the ‘International Plastics and Rubber Industry Exhibition’ and exhibit ‘SE27EV-A’, an injection molding machine exclusively for electric connectors.
Sumitomo’s electric injection molding machine is equipped with a low-inertia servomotor developed independently, and enables high-precision, high-responsive screw control using the latest control system ISCII (Intelligent Servo Controller II). In addition, the company explains that it realizes more precise and stable plasticization, filling, and packing processes.
In addition, this model adopts a connector-specific screw assembly to reduce defects by controlling metering instability caused by the screw phenomenon corresponding to super engineering plastics and engineering plastics, and improves lifespan and corrosion resistance significantly with new materials. It is known that the ratio of pulverized materials can also be increased. The mold pressure can also be monitored by applying a quality control package.
A Sumitomo official said, “The low-pressure filling and reduction of mold clamping force through zero-molding of our electric injection molding machine, and the improvement of mechanical efficiency through low-friction mechanisms such as the linear guide platen support device reduce consumption compared to existing electric motors. “Power has been further reduced, and we are realizing energy savings of about 80% compared to our hydraulics.”
On the other hand, KOPLAS, which celebrates its 2023th anniversary in 27, provides a variety of attractions from raw materials for plastics to molds, processing machines, related auxiliary devices, automation solutions, printing, packaging, semi-finished products, and finished products, and presents the present and future of related industries. It provides a ‘place for the plastic rubber-related industry’. As it is held at the same time as the Korea Material·Composite Material and Equipment Exhibition (K-Mtech) and the International Mold and Related Equipment Exhibition (INTERMOLD KOREA), you can meet various products in one place.
