Diagonal cutters for plastic and other soft materials
Why special diagonal cutters are needed for plastic
The cutting edges of diagonal cutters used for wire are ground to produce a wedge-shaped cut towards the centre of the cut product. This wedge ultimately splits the cut material apart, and the wire ends separated in this way have wedge-shaped cut surfaces. A flush, smooth cut is desired when separating moulded parts and sprues, in order to create the least finishing work when deburring.
Diagonal cutters used here must not have any bevel so as to create a straight cut surface. The Knipex 72 01 160 diagonal cutters have been specially developed for plastics and other soft materials. Their cutting edges are surface ground.
For flush deburring after injection moulding
The Knipex 72 01 160 is used in plastics production when, for example, plastic moulded parts need to be mechanically separated from sprue after demoulding. The surface ground cutting faces permit the clean, flush disconnection of extruded plastic injection moulds and sprues or sprue residues. The sprue is cut off directly on the moulded part, because the cutting edge runs parallel to the component.
With opening spring to relieve strain on the user – compact and stable
In many cases, work steps in plastic injection moulding and other production processes repeat. Anyone who frequently separates sprues from moulded parts therefore appreciates the opening spring on the Knipex 72 01 160, because it saves an additional hand movement every time. At 160 mm long and weighing 164 g, the Knipex diagonal cutters for plastics are compact enough for mobile use in production. They are designed for many years of hard use in industry. We forge the 72 01 160 diagonal cutters from vanadium electric steel. We give them their high strength by heating and then quenching them in oil.
