Factors affecting injection molding: Second, pressure-controlled injection molding process pressure comprises two plasticizing and injection pressure pressure, and directly affect the quality of plastics and plastic products. 1, plasticizing pressure (back pressure) using a screw injection machine, the top screw melt in the screw rotates backward suffered pressure is called plasticizing pressure, sample processing nylon machining parts, also known as back pressure. The size of such pressure can be achieved through the hydraulic system relief valve to adjust. That will increase the temperature of the melt in the injection, the size of plasticization pressure with the screw speed is constant, the increase plasticizing pressure, but reduce plasticizing speed. In addition, increased pressure often make plastics melt temperature uniformity, Baoji machining parts, mixing and discharge gas melt toner. General operation, decided plastics pressure should be to ensure good quality products under the premise as low as possible, the specific values ??are used with different varieties of plastic, nylon machining parts, but are rarely more than 20 kg / cm . MC nylon products mechanically strong, self-lubricating, excellent wear resistance, suction noise, most durable nylon machining parts, impact-resistant, easy to hold the shaft, sintering, not to hurt the journal, long lubrication cycle, glass fiber beads, graphite and other chemical materials, physical properties make it more resistant, longer life, Dezhou Composites Co., Ltd. Wang Yue two decades do matching for domestic machinery plant has made good use of effects. The most durable nylon workpiece, Texas Hongyue best (online consultation), Baoji workpiece by Wang Yue Dezhou Composites Limited. Wang Yue Dezhou Composites Co., Ltd. (www.dzshyfhcl.com) (www.dzshyfhcl.com) (www.dzshyfhcl.net) Shandong Dezhou, chemical products processing leader, over the years, the company implement the scientific management, innovation and development , the principle of honesty and trustworthiness, and satisfy customer needs. Wang Yue in Texas led the staff warmly welcome all inquiries negotiations to create the Texas Hongyue better future.
