Innovation in hot runner design: Precision in the tightest of spaces with 32 injection points on just 70 x 35 mm GÜNTHER is setting new standards in hot runner technology with the successful realisation of a new type of valve gate system. The system impresses with its extremely narrow gating dimensions and an impressive number of 32 injection points on an area of just 70 mm x 35 mm - an achievement made possible by close interdisciplinary cooperation between the mould maker and hot runner supplier. Valve Gate System with Servo Drive The focus is on a high-precision electric valve gate that allows the needle position to be adjusted easily and precisely. This is supported by a specially developed sliding mechanism with recirculating rollers, which ensures powerful and concentrated force transmission - and thus guarantees reliable, precise closing of the valve pin directly at the injection point. The interaction of these components significantly increases both process reliability and reproducibility in series production. The modular concept is scalable to up to 96 injection points and therefore offers a high degree of flexibility for a wide range of mould concepts while at the same time minimising space requirements. Particular attention was paid to homogeneous temperature control in the melt-flowing areas. Adapted control zones ensure uniform heating, while the balanced melt distribution via optimised channel design in the manifold enables constant filling of all cavities - even with complex geometries and high numbers of cavities. The needle guide made of wear-resistant material also guarantees a permanently high injection point quality and a long service life in continuous operation. The system is rounded off by a temperature control concept developed together with the mould maker, which enables precise coordination between the mould and hot runner components.
PRISMA Nozzle
The hot runner specialist's newly developed PRISMA nozzle offers particular advantages for rotationally symmetrical articles with high demands on concentricity that have to be moulded several times. The new nozzle that Günther Heißkanaltechnik, Frankenberg, will be presenting at KUTENO 2025 is designed for precision production. Thanks to the special melt guidance, it is designed to enable precise injection moulding processes, even with narrow stitch dimensions and small pitch circle diameters. The nozzle is particularly suitable for demanding, technical plastic parts with high requirements for shape and position tolerances as well as confined spaces.

According to the company, initial series production runs have already confirmed the performance and reliability of the nozzle, which emphasises its high standard in practice.
