In the traditional mould design, the ejector package essentially consists of an ejector base plate and an ejector retaining plate and is crucial for clean demoulding of the injected plastic parts. The so-called recoil pins bring the ejector pack back to its original position after a demoulding cycle. In many cases, end position sensing of the ejector plates are carried out to prevent damage to the tool.

Often underestimated, limit switches do a great job with regard to a permanently stable and reliable production of plastic parts. By polling the end position, for example, stripper plates, ejector packages, core pulls or slides can be secured, thus avoiding an expensive tool crash. The optics of the limit switches are characterized by a high quality and robust aluminium housing with encapsulated electronics inside that are secured against short-circuit. The micro switch, which is installed inside this housing, is triggered by either a mechanical or an inductive pulse.

Knarr provides the ejector package as a pre-assembled unit for both System F (15900) and System K (10670). This includes matching cylinder head — (40031) and countersunk screws (40033) as well as with fitting support washers (51055). It is available in different materials or as compatible material pairings and speeds up both the selection and ordering process.
