made in Helmbrechts Contrary to the simple open-close tools, for more complex forms, only one demoulding direction is no longer sufficient. If contours on the plastic part stand in the way of this main demoulding course, their release requires...

As a supplement to the previous range (Ø10 mm, Ø13 mm, Ø16 mm, Ø19 mm, Ø22 mm and Ø28 mm), KNARR now offers the slide holding device with roll in Ø42 mm. Springs of different strengths allow retention forces of 80 kg, 120 kg or even 160 kg and...

Two surfaces for clear positioning The standardized, space-saving head shape of the ejector pin ensures its distinct position in the tool. Different surfaces on both sides  allow mounting only in the exactly desired position and prevent...

More safety with increased tool efficiency The melting of thermoplastic materials requires temperatures of several hundred degrees Celsius. In many cases, thermal separation of the injection-moulding machine from the mould mounted in it is...

Easy positioning of the mould insert In the case of moulds with interchangeable inserts, positioning wedges ensure high-precision installation positioning and at the same time allow the necessary clearance for easier installation and...

with O-Ring In order to avoid distortion of the plastic part, a homogeneous temperature balance in the mould is crucial. The positioning of the cooling channels plays an important role. Once this is done, the right sealing becomes the next...

Optimal distribution of the closing pressure A stable, permanently high-quality production of plastic parts is also a matter of the closing pressure. In order to avoid burrs, in the cavity area, the closing pressure is often at its maximum....
