Plastic profile extrusion mold half technical requirements and state >> plastic profile extrusion dies extrusion materials especially when modified PVC pvc plastic pipe fittings, which molded parts are generally made of stainless steel and other corrosion resistant materials, and to adjust quality to HRC24 or more, in order to guarantee a certain life. >> Die, mold and parts stereotypes work surface should be smooth, there should be no bumps, scratches, burrs, rust deposits and other defects. >> Die runner system along the melt flow direction should be gentle pvc plastic prices, to avoid cross-section of mutations and stagnation feed zone. >> Between each template should be a reliable positioning, inter-modal inter corresponding template loading position repeatability error is not greater than 0.03mm; plastic profile extrusion die and die all joints should be a good seal split Mian, its local gap shall not be greater than 0.02mm. >> Stereotypes mold cooling system, vacuum system should be smooth, non-disclosure, in general, the water gas systems should not collusion. Plastic profile extrusion die stereotypes die pipe fittings, tube fittings should be clearly marked, and shall not affect the piping connections. >> Plastic profile extrusion die should play off stereotypes die flexible pvc plastic supply, mold and shape each section of the tank-block should be guaranteed concentricity. Import PVC phase mixing in heterogeneous polymer phase - polymer melt blending is a simple and effective method for modifying and has accumulated experience in the actual production. Generally when two or more different polymers melt blended, both the nature of these polymer mixtures can be prepared. In order to improve the fluidity of rigid PVC, impact properties, etc., the most commonly used polymer blends are: acrylonitrile - butadiene - styrene (ABS), which is mainly to improve the impact strength. Methyl methacrylate - butadiene - styrene (MBS), in addition to weather resistance, the rest of the performance are nearly ideal, especially impact strength, as long as a small amount can be greatly improved. Chlorinated polyethylene (CPE) can improve the impact strength, if the added amount of 20%, the impact strength can be very high. Ethylene - vinyl acetate (EVA) can improve the impact strength.
