Ewikon Solutions for multi-tip and valve gating with a focus on compact multi-cavity applications
Germany – Ewikon will be showcasing solutions for multi-tip gating and valve gating with a focus on compact multi-cavity applications.
When designing compact multi-cavity moulds for direct side gating, the Ewikon HPS III-MH nozzle concept is said to offer one of the most advanced multi-tip solutions available today. The patent pending installation technology for the tip inserts allows for easy installation and exchange from the parting line of the mould and requires only standard mould inserts, Ewikon says. The nozzles come in several sizes for shot weights of up to 40 g per gate and are available for linear or radial arrangement of parts. For process-reliable valve gating, Ewikon offers several drive versions for adaptation of the valve gate system to specific application requirements. The range includes hydraulic and pneumatic drive units for single nozzles and synchronous plate solutions for precise joint valve pin actuation. This is suitable for applications with a high number of cavities, close cavity spacing or small shot weights as it guarantees an even filling of all cavities with high reproducibility, Ewikon explains. Another option, the clean-room-compatible electric drive unit with a step motor and a touch screen control, is for precise valve pin positioning and individual setting of process parameters.
Most multi-cavity hot runner solutions today are delivered as complete hot halves, easing installation and system start-up with hardly any on-site adjustments, the exhibitor says.
