NOZZLE SEAL-OFF REPAIR
A common problem with older systems is wear at the nozzle seal-off diameter, which allows plastic leakage down the nozzle and around the heaters.
The HotRunnerSpareParts.com solution involves micro welding and grinding the seal-off diameter to original factory tolerance. The cost is a fraction of a new housing.
VALVE BUSHING REPAIRS
Typically, the valve pins wear preferentially to the bushing on valve gate systems. But on older systems, the bushings can need replacement.
HotRunnerSpareParts.com offers an alternative to very expensive bushing replacement. We precision hone the valve pin passage and then manufacture slightly larger valve pins. This typically reduces repair costs by 50-67%.
INTEGRALLY HEATED NOZZLES
Repairing damaged nozzles offers significant savings over replacement.
Molders can experience two types of problems:
First is damage to the heater termination. HotRunnerSpareParts.com has developed a technique to repair even the most damaged termination.
The second is damage to the tip. This typically occurs when trying to remove or replace the tip assembly. We can quickly remove the tip – even carbide – with no damage to the thread or seal off areas.
