Project Description
EWIKON hot runner nozzles come with a multitude of available flow channel diameters, nozzle lengths and gating options offering utmost flexibility for mould designers.
More information:
EWIKON nozzle technology – Temperature stable, robust and easy to maintain
- Process-reliable through direct heating
Coil heaters and thermocouples directly integrated into precision-machined cutouts in the melt bearing pressure tube. Very stable heating with minimised loss resulting in an even temperature profile along the whole length of the nozzle. The even heating of all nozzles guarantees a high process reliability and an excellent system balance. - Hardened pressure tubes
For melt pressures up to 2000 bar. Wear-resistant threads for problem-free repeated disassembly of tip insert. - Easy maintenance and replacement
Front installation for easy access and replacement of nozzle after dismantling of cavity plate. Exchangeable tip inserts, heaters and thermocouples. - Stainless steel protective tube
Prevents damage to the heater. - Quick colour changes
Melt seal directly at the gate. Only a minimum melt volume needs to be exchanged.
Gating options
Various gating options allow utmost flexibility in gating point position and design.
- Gating with heat conductive tip
- Valve gating
- Gating with open flow channel
- Various versions of gate bushes and screw-on gate bushes including overdimensioned versions to adapt to free form contours
