HPS III-MH The versatile multi tip solution Direct side gating without cold slug Compact valve gating Side gating with open flow channel

The user-friendly concept No matter if the application requires a solution for efficient side gating or for compact valve gating of parts – with the HPS III-MH product line EWIKON provides a powerful and versatile multi tip concept for injection moulders and mould makers. All nozzle versions offer a unique ease of maintenance. Especially the patent pending version for direct side gating has set new standards here and is successfully used in many demanding applications in the medical and packaging industry. The results: reduced cycle times, enhanced productivity and cost-efficient mould design....

Medical. Packaging. Technical Parts. Fields of application Side gating • Part geometries without possibility of standard gating, for example long slim tube shaped parts such as syringes, pipettes or sample bulbs in the medical industry. • Side gating on visible surfaces. Demoulding mostly takes place in a 90° angle to the gating direction. The shear action is used to achieve a good gating point quality. • Multi point internal gating of rotationsymmetric parts, for example in spouts of screw caps in the packaging industry. Compact valve gating Multi point gating of parts, gating on horizontal...

Direct side gating The benchmark for direct side gating Its patent pending tip exchange technology makes the HPS III-MH nozzle the most maintenance-friendly solution for direct side gating worldwide. Depending on shot weight and application several versions are available. The tip inserts are installed from the parting line of the mould in the last assembly step after the nozzle body has been installed. Thus, they can be exchanged easily without having to dismantle the mould. Since only standard mould inserts are required a cost-efficient and compact mould design can be realised. Alternatively...

Cost-efficient mould design with standard mould inserts Easy accessibility of tip inserts for maintenance Easy replacement of tip inserts 1. Remove the end cover flange 2. Pull tip insert out of mould insert for replacement Product features + Benefits • Direct gating on part surface, no cold slug • Fully balanced flow channel layout in the nozzle body • Even temperature profile • Requires only standard mould inserts resulting in enhanced mould stability, easy cooling and reduced mould costs • Utmost ease of maintenance, easy replacement of tip inserts from the parting line, minimised downtimes...

Valve gating Ultra-compact valve gating The HPS III-MH valve gate technology features a lateral melt feed*. The gate is positioned in demoulding direction (0°). A special characteristic is the position of the valve pin guides and seals in the cooled mould insert. This ensures leakproof operation of the system. The concept allows ultra compact valve gating with a minimum distance between cavities of only 6 mm. Furthermore, gating points can be positioned in hard-to-reach areas such as horizontal surfaces close to vertical walls, for example onto handle plates of syringes or flanges of analysis...

Technology of the valve gate version Pneumatic drive unit Synchronous plate Standard mould insert The combined valve pin guides and seals are installed in the cooled standard mould insert. This guarantees a leakage-free operation. Special heat conductive elements embrace the valve pin contactless near the gate and ensure a homogeneous temperature profile in the gate area. The valve pin guide and seal is positioned close to the gate leaving a free valve pin length of only 5 mm. Product features + Benefits • Valve gate technology with synchronous plate actuation. Simultaneous opening and closing...

Versions and suitable materials Gating options 60° gating Advantage: The gating point can be positioned closer to the core location of the cavity when moulding slim, thin-walled tubular parts for the medical industry. Thus, core deflection by the melt pressure, which leads to uneven wall thickness, can be reduced or completely eliminated.
