Ejector Pins With Ventilation Surfaces Improve Mold Performance

Hasco America unveils its new ejector pins Z401 with ventilation surfaces to ensure that the air in the cavity can easily escape, improving mold performance. Specific to this product, the extra-long ventilation surfaces extend over a large part of the ejector pins, so the pins can be easily and individually shortened to the desired length.

During the injection molding process, cavity ventilation must be ensured to help achieve an optimum result when filling with plastic — especially at the end of the flow path, Hasco notes — in addition to preventing the so-called “diesel effect.” Ejector pins provide ventilation via the parting plane of the mold through slides, cores and mold inserts.

The new ejector pins are available in different diameters (1-12 mm) and lengths (100-315 mm, depending on the diameter), and can be interchanged directly with conventional ejectors Z40 or Z41. Overall, Hasco says it is able to comply with customers’ individual requirements, offering maximum flexibility, especially in the field of demolding.
