China plastic pipe industry in the development, some problems are increasingly apparent. Especially less variety of raw materials, the quality of instability, price volatility, lack of special, product quality can not be guaranteed, the product structure, production scale is unreasonable, the overall poor production equipment, product quality, management confusion, standards, specifications, drawings, set quotas and other serious lag, poor matching plastic pvc pipe prices, can not meet the development needs and the lack of practice tests and other factors severely restricted the further development and quality improvement industry. Therefore, pvc plastic pipe fittings, plastic pipe Chinese enterprises must seize the new developments, attention to production, research and development, regulate industry positioning of raw materials, improve the quality management measures to regulate the sales market, strengthen macro-control and guidance, develop, and improve the relevant standards and technical and economic policies, strengthen cooperation and improve the sound of plastic piping systems, the only way to be invincible in the new situation. PVC (polyvinyl chloride) chemical and physical properties of rigid PVC is one of the most widely used plastic materials. PVC material is a non-crystalline materials. PVC material in actual use, often by adding stabilizers, lubricants, auxiliary processing agents, pigments, impact agents and other additives. Runners and Gates: All conventional gate can be used. If the processing of smaller components, it is best to use the tip gate or sneak into the gate; for thicker parts, it is best to use the fan gate. The minimum diameter of the tip gate or sneak into the gate should be 1mm; fan gate thickness not less than 1mm.
