Mold-Masters MasterSHIELD Technology is an innovative patent pending spring design that pre-loads the nozzle to the manifold. This enhanced sealing feature offers greater production reliability through enhanced leakage protection during cold start-ups and in the event of accidental overheating. MasterSHIELD Technology allows for a much wider and more reliable range of operation that minimizes excessive load on the entire stack.
The robust design maintains a more consistent sealing force which minimizes the risk of plate deflection/bowing +/- 100°C (180°F) from processing temperature. This also allows for relaxed tolerances on plate manufacturing for mold makers.
Mold-Masters MasterSHIELD Technology can be found as standard components on SPRINT and ThinPAK-Series Hot Runner systems.
