Highly corrosion resistant Traditionally, the topic of “cooling and temperature control” plays an important role. After all, the right mould temperature control is crucial in terms of quality and efficient production of plastic parts....

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. Hardened...

for die casting applications In die casting applications, the mould and built-in parts are exposed to high thermal and mechanical loads. Compared to classic injection moulding, these requirements cause much higher wear. In both cases, however,...

150 additional dimensions As the industry leader in “ejector technology”, KNARR is expanding further. In addition to the enhancements within the ejector sleeve and flat ejector categories, 150 new dimensions complement the available...

Updated SolidWorks standard parts library and STEP data collection In just a few mouse clicks, our web shop offers useful and timesaving help for your design. All 3D geometries are available for download at article level. But not only that:...

Standardized product variety: 400 new sizes Flat ejectors prove to be extremely beneficial in constructively critical areas. Ribs on the plastic part can be demoulded without any problems, to name just one advantage. The classic, sharp-edged version...

140 new dimensions As part of a program expansion, KNARR is standardizing around 140 new ejector sleeves. More than two-thirds of the dimensions complete the “stepless sleeves” product family. KNARR with pioneering role In the...

Design and manufacture of an injection moulding tool for reusable plastic cups The in-company vocational training and encouragement of our junior staff is a firmly anchored element within the KNARR company philosophy. Optimal and practice-oriented...

for system F and system K 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...
