Selection.
We offer pneumatic and hydraulic drives for installation in the clamping plate and on the hot runner manifold. In addition, there are designs with additively manufactured housings for particularly tight installation spaces for pneumatic drives. Electric drives for lift plates, including control, are also available.
We are happy to advise you on the best possible drive concept for your planned application.

MONOLITH®
Be inspired by the additively manufactured technology that shifts the known boundaries of conventional hot runner technology. Homogeneous melt guidance and perfect temperature profiles ensure optimal material processing. Higher process stability and reduced downtime are the result. MONOLITH® – the new generation of hot runner nozzles from WITOSA.

03:format(avif):quality(75) "Hexagonal carbon structures with honeycomb interiors levitate over a black hexagonal surface with glowing red edges.")
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.

Hot runner manifold
We manufacture hot runner manifolds for you with shrink-fitted deflection elements. This process perfectly combines rounded melt channels with ideal surfaces. For precisely balanced filling studies, we also compensate for shear differences and melt orientation in our manifold systems.

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.

XS Systems
Our XS linear system is designed for lateral injection with small cavity distances and part weights of up to a maximum of 15 grams. The MONOLITH® nozzles are screwed to the manifold and connected leak-proof. Nevertheless, short, delicate nozzles can be realized due to the intelligent system structure. The system is therefore very easy to install and simple to handle.

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?
