The application of high transparency, high viscosity, easy-cracking, high molecular weight plastic filter characteristics: Modular steel leak-Proof, they are free to wear steel disassembly, do not have to be processed. Plastic flow does not stay, stay a short time. May be a result of processing temperature on the metal expansion coefficient of issues expected to adjust the leak site. Hydraulic hole to hole to start for network time is about 0.01 seconds, production is not interrupted. Hole steel filter can be removed separately to ensure that the disposal of plastics stranded hole quickly update clean hole steel filter, filter to ensure that after the plastic is the most clean, and warm-up device, for network and not to plastic flow of cooling down.
