04:format(avif):quality(75) "A metallic device with numerous vertical pegs on a hexagonal pattern background with red lighting accents.")
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.

07: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.
