The cold runner block device consists of three parts.
It has a circulating water pipe inside, which can keep the temperature down while working. So, it is always in alow temperature working state to ensure that rubber will not vulcanize and thus cause blockage.
Through scientific design, it can change the position and quantity of injection nozzle and ensure the balanceof injection at each injecton nozzle.
Heat insulation plate
It is composed of asbestos insulation plate and resin insulation plate, which can minimize heat transferringfrom heating plate to runner plate, and it has high strength so that it is not easy to break.
It is used to provide heat for mould, so that the temperature of mould can reach and stabilize at the vulcanization temperature of rubber.
