CAE Services cuts injection mold scrap by 85%
CAE Services, a consulting firm offering advanced solutions and professional expertise for the plastics industry, announced its customer Ventra Plastics in Windsor, ON, recently achieved major manufacturing success as a result of using CAEís Mold-Vac 10,000 system. The system is a mold evacuation product designed to eliminate entrapped air and gas within a mold cavity prior to and during plastic injection molding.
Ventra Plastics, a plastic injection molder servicing the automotive industry, seeks innovative production solutions to ensure improved product quality, production efficiency and control, as well as reduced costs. Ventra process engineering Frank Massimino successfully reduced reject rates from 15% to 1% by using the system.
At that time, Massimino was working with a filled TPO material to mold an interior automotive trim component. He faced challenging operation parameters that included the heat profile of the barrel, mold temperatures, and fill speed profiles. All issues required a narrow molding window that resulted in unacceptable gas burns and knit lines on the part.
CAEís engineering team evaluated the Ventra part and determined that because of the gas trap location, it was indeed a candidate for Mold-Vac 10,000. The system has been running in Ventraís Ontario plant for one year with impressive results. CAEís gas evacuation technology successfully opened the molding window and Ventraís product quality problems were eliminated.
In addition, as a result of implementing Mold-Vac 10,000, Ventraís mold maintenance costs have been significantly reduced. Massimino said, ìMold-Vacís unique blow-back control feature ensures that vented pins are cleaned and purged after every cycle. After installing Mold-Vac, we immediately noticed less build-up of volatiles on ejector pins and around part periphery. The vents on the mold required less cleaning. Therefore, weíve been able to reduce our monthly preventative maintenance.î
To use Mold-Vac, a slight modification of the mold is required. Ventra Plastics installed a rubber seal around the parting line to eliminate all the gas from the cavity and core. The cost of the modification varies depending on the size of the mold and the size and geometry of the part.
