Why special diagonal cutters are needed for plastic
Diagonal cutters for wire have bevels on the cutting edges, producing a wedge-shaped cut towards the centre of the cut product. From a physical point of view, this wedge splits the material to be cut apart. The wire ends have wedge-shaped cut surfaces as a result. A flush, smooth cut is desired when separating moulded parts and sprues, however, in order to create the least finishing work when deburring. Diagonal cutters used here should not have any bevel towards the component to produce a straight cut surface. The cutting edges of the Knipex 72 11 160 diagonal cutters are surface ground. The sprue is cut off directly on the moulded part because the cutting edge runs parallel to the component
Cutting edges at a 45° angle for deburring in poorly accessible areas
The Knipex 72 11 160 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 are at an angle of 45°. The clean, flush disconnection of extruded plastic injection moulds and sprues or sprue residues is therefore also possible on difficult to reach areas, for example on large and angular components.
