Hot runner intermediate plates

Hot runners in intermediate plates connect the nozzles of the injection units with the tool injection bushings if their positions are different. The hot runners are slidably mounted in the intermediate plates in order to achieve different positions of the tool injection bushings in relation to the clamping surface. The contact force of the hot runner nozzle to the mould injection bushing is generated via a setting device. The contact force to the tool mould sprue bushing is infinitely adjustable independently of the machine and can be permanent or cyclical. The hot runner intermediate plates are manufactured with threaded holes according to EUROMAP2 or T-slots. Exchangeable nozzles and injection bushings for the hot runners, the cooling of the steel plate and a heat insulation plate are included in the standard equipment.

Advantages and applications of hot runner intermediate plates

• Maximum leak-tightness thanks to the safe, adjustable frictional connection of the tool injection bushing to the hot runner nozzle
• No machine and / or tool modification required
• Long service life due to extremely short down times and cost savings even with frequent tool changes
• Easy assembly / disassembly of the hot runner plate – comparable to a tool installation or removal
• In the event of servicing: easy removal of the hot runner plate from the steel plate
• Integration of additional sensors, e.g. for monitoring the nozzle contact force – Industry 4.0 capable
• Expansion of the technological possibilities of the injection moulding machine through additional special injection moulding processes
