Multi-drop valve gate nozzles
Multi Hot Runner Nozzles “ClusterFlow”: Direct valve gate injection in the smallest installation space
The system impresses with extremely tight pitch dimensions and an outstanding number of 32 gate points within an area of just 70 mm x 35 mm.
At the core is a highly precise electric valve gate system that allows simple and exact adjustment of the needle position. This is supported by a specially developed sliding cam mechanism with circulating rollers, ensuring powerful and focused force transmission - guaranteeing reliable and precise needle closing directly at the gate point. The interaction of these components significantly increases both process reliability and reproducibility in serial production.
The modular concept is scalable up to 96 gate points, offering a high degree of flexibility for a wide range of mold designs while maintaining minimal space requirements.
The nozzle features homogeneous temperature control throughout all melt-carrying areas. Optimized control zones ensure uniform heating, while balanced melt distribution via an optimized manifold channel design enables consistent filling of all cavities - even with complex geometries and high cavity counts.
The needle guidance made of wear-resistant material additionally ensures consistently high gate quality and long service life in continuous operation.
This technology provides future-proof solutions for the increasing demands of miniaturization and multi-cavity production.
Multi-Drop hot runner „Prisma Nozzle“: Highest precision on smallest area
Multitip gating with high gate point quality
The Prisma nozzle sets new standards in precision. Its advanced multiple connection with valve gate enables a very high injection point quality, even with the smallest pitch circle diameters. The precisely uniform opening and closing of the injection points ensures maximum precision during processing and individual adaptations to different requirements.
The PRISMA nozzle is available with two, three, four or five gating points.
Durability and highest quality
Developed for a long service life and maximum precision, the PRISMA nozzle impresses with its innovative design. The replaceable needle guides made of PM steel achieve a long service life and are easy to replace when servicing is required. The needle is positioned outside the melt channel and is only heated by the plastic melt in the gate area. This nozzle design is ideal for applications with high demands on process reliability and product quality.
Your benefits:
- Precise valve gate technology with minimal space requirements
- Precise gating points with the smallest pitch circle diameters
- Individually adaptable for different applications
- Durable construction with minimal wear
- Optimum heat distribution
Optimum heat distribution for efficient injection moulding
The PRISMA nozzle is characterized by a very homogeneous temperature profile in the melt channel. The design with a twopart shaft in the combination of titanium alloy and tool steel results in optimum thermal separation between the tool and hot runner. The melt is not thermally damaged. Good concentricity properties can be achieved when connecting with several gating points and uniform opening of the gating points.
