⬢E-Mobility
Maximum performance for high-performance materials.
In battery housings, cell holders, connectors, and structural components, flame-retardant, glass- or mineral-filled, and chemically highly resistant plastics are increasingly being used. These materials are abrasive, temperature-critical, and challenging to process.
Our additively manufactured MONOLITH® nozzles offer:
Optimized, streamlined melt channels for highly filled compounds
Homogeneous temperature control even with difficult-to-process FR and battery acid-resistant materials
Reduced shear rate for sensitive flame retardant systems
Minimized pressure losses at high fill levels
Extremely wear-resistant design for abrasive materials
The result: stable processes, reproducible quality, and longer mold life.

Hot halves
Hot halves combine precise temperature control with maximum user-friendliness. Thanks to their convenient adaptation to a wide variety of tool shapes, Witosa hot runner systems can be quickly and safely integrated as a hot side. Through thoughtful design, high-quality materials, and tested components, hot sides offer the highest level of process and operational safety – for reliable results in daily use.

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.
