The problems associated with injection moulding machines are in two areas, the tool face and collection bucket or conveyor line. When small parts are ejected from the tool face they can be attracted to the tool face (earth potential) as they fall away. This can cause damage to the tool, rejects, down time and a loss of productivity.

        When the parts fall into a collection bucket or container, they w?ll start to cool and stat?c w?ll be generated. Th?s charge, although small on each ?nd?v?dual part w?ll create a very large electro-magnetic field as more and more parts enter the collection area. Th?s w?ll lead to contamination being attracted into the container as well as operators in the area w?ll absorb the charge into their bodes and discharge (often very violently) when the come into contact with an earth potential (mach?ne, door handle or another operator). The shock received by an operator is not dangerous, but the involuntary reaction to the shock can be very serous if working in close proximity to working machines. When parts fall onto a moving conveyor, the stat?c charge w?ll attract contamination from the air and th?s w?ll become bonded to the part. Th?s can cause quality issues ?f the part has to be painted or is used as a food or pharmaceutical container.

        Tool face

        By positioning a PULSElectron?c air boost bar across the top of the tool face, you can blow a blade of ?on?sed air down across the face when the tool opens. Th?s w?ll remove any statically attracted products or particles and ensure that the tool face remains clean. To reduce the amount of compressed a?r used, PULSElectron?c recommend that you f?r a solenoid and relay valve that w?ll only blow the ?on?sed a?r across the tool face as the tool opens.

        Collection container

By positioning a PULSElectron?c ?on?s?ng a?r blower that w?ll blow ?on?sed a?r ?nto the container as the parts fall from the tool face, you w?ll, Prevent large stat?c charges from building up, remove the electro-magnetic field and el?m?nate the possibility of contamination being attracted onto the product.

        Conveyor belt

        By positioning a PULSElectron?c ?on?s?ng blower across the conveyor belt you w?ll aid in the cooling of the part, remove any stat?c charge on the part and el?m?nate the possibility of contamination being attracted to the part. In all cases the removal of the stat?c charge w?ll protect the safety of operators who work within the electro-magnetic field generated.
