Luliang hydraulic Acoustic Pipe PM-35 Hydraulic Acoustic Pipe is a ball park by ultrafine particles at high temperature sintering of stainless steel powder, covered with tiny uniform in all directions inside the vent, also called porous material or porous metal, Application of trapped gas in the injection mold, etc., there are three models PM-35-7 microns (7 microns small pores), PM-35-25 microns (25 microns in pores), PM-35-35 microns (35 microns large pores), provided by the United States International Mold Steel Technology (INTERNATIONAL MOLD STEEL, INC.), Japan's new East (SINTOKOGIO, LTD.) production. Factory Status: Pre-hardened to HV350-400 (HRC35-40). PM-35 Hydraulic Acoustic Pipe is a can "breathable" of high-quality steel, refining, made by powder sintering technology. Contains a series of internal pore diameter of 10 microns, accounting for 20% -30% of the total volume of steel This particular structure, not only has breathable capabilities, while maintaining the required injection mold high strength, high hardness and corrosion resistance. Therefore, an appropriate location for injection mold bordered PM-35 Hydraulic Acoustic Pipe, a gas formed by injection molding problems can be completely removed, so that forming a more perfect. In addition, PM-35 Hydraulic acoustic tube with good mechanical properties, the use and manufacture of plastic injection molds, die steel can be generally the same processing methods, such as cutting, grinding, EDM and so on. Hydraulic Acoustic Pipe Alias ??PM-35 Hydraulic acoustic tube, porous metal, porous mold steel, breathable metal, PORCERAX Ⅱ Hydraulic Acoustic Pipe, PM-35 Hydraulic Acoustic Pipe, injection molds for hydraulic Acoustic Pipe mold hydraulic Acoustic Pipe, powder sintered stainless steel, breathable materials, porous materials, acoustic hydraulic pipes, breathable die steel, steel exhaust, exhaust material. Hydraulic characteristics of an acoustic tube surface striae plastic parts, due to the high temperature and pressure generated by light sticks, can solve the requirements matt surface. Second, to reduce and eliminate stress molded parts, to prevent distortion and warped products. Third, reduce the injection pressure, and dwell time to reduce the molding. Fourth, due to the tight fit to the mold parting surface, the mold can solve the problems and so on. Solving often use a thimble, inserts, etc. can not provide sufficient surface area to accommodate the many problems that may arise, such as large amounts of gas, to avoid the use of flash and other sub-surface defects or other exhaust system generated. Fifth, make the deviation due to the gate, wall thickness uneven, thin wall molding products and other difficult issues have been resolved and mitigation. Six, due to gas and mold cavity molding material produced rapid poly-pressure high-temperature char produced, flow marks, shut, breathing part deformation caused by defects can be fully resolved. Seven to improve molding productivity, reduce production costs.
