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...

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....

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...

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...

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.
