1. Pelletizer Extrusion die of plastic after the arrival of out of the box check the packaging intact: when unpacking remove packing list, check out of the box. Technical documents such as manuals, formed by the contents of the packing list check the mold parts, accessories, special tools, etc.
2. half of the extrusion tooling technology requirements and status of molded parts made of stainless steel and other corrosion-resistant material, extrusion die especially when extruded materials as modified PVC. And tempered to HRC24, in order to ensure a certain degree of life. There should be no bumps, scratches, burrs, and attachments, as well as corrosion and other defects. Die, molding and parts of the work surface should be smooth. To prevent mutation of the section and the lag zone. Die melt flow direction flow system should be gradual. Mould loading repeatability error corresponds to the template location is not more than 0.03mm Extrusion die head the jointing surfaces and flattening should be a good fit, the template should have a reliable positioning. The local clearance shall not be greater than 0.02mm
General plastic granulator water systems should not collude. Extrusion molding of the hose joint molding cooling systems, vacuum systems that often, is not revealed. Vacuum fittings should be clearly marked and should not affect the piping connections.
