Suction blow molder produces complex parts

Dec. 1, 2019
The ASPI 200 is designed so that the parison gets sucked into the mold when it is already closed, saving energy and plastic.
ASPI 200 Designed for processing polyolefins, engineering resins, carbon-fiber-filled materials and high-temperature resins, this new suction blow molder from ST BlowMoulding SA, Stabio, Switzerland, can produce complex parts thatare angled in multiple orientations. For instance, it can make under-the-hood automotive ductwork and pipes, as well as smaller, more conventional blow molded items, such as tanks for windshield washer fluid. Hollo Plastics represents ST BlowMoulding in the U.S.

What’s new? The machine, featuring a tie-bar-less clamping unit, radial-wall-thickness control system and patented parison diameter control. Since exhibiting a prototype at K 2019, ST BlowMoulding plans to launch a commercial version in the next few months.

Benefits Substantial savings in the amount of plastic and energy needed to create a part. Unlike other blow molding setups, in which the parison is extruded between two open mold halves, then squeezed as the mold closes, the ASPI 200 is designed so that the parison gets sucked into the mold when it is already closed. This difference eliminates the creation of lateral flash.
