Linear systems
Lateral injection with full process control and evenly adjustable filling studies. Standard multi-nozzles with passively heated tips are yesterday's technology for us. Systems with one nozzle and one control point per injection point are our standard - even in lateral connection... Do you also want full process control?

Energy Blocker®
3D printed Energy BLOCKER® made of hardened steel reduce the energy consumption of your hot runner manifold by up to 52% compared to conventional hot runner systems with titanium pressure pads, depending on the application. The thermal insulation of the Energy BLOCKER® in relation to your tool not only saves energy costs during the operation of the hot runner system but also reduces the necessary cooling capacity for your mold. This results in additional energy savings.

MONOLITH® Single Nozzle
Whether prototype, pre-series, or small series mold with a low number of cavities - every article deserves quality and process stability. Easy to integrate: As it is adapted to standard centering rings and mounting plates, the nozzle integrates effortlessly into any standard mold structure. See for yourself...
