This page presents the technological and production advantages of an innovative PET preform mould. Its unique design eliminates the need to cool and reheat the hot runner during part changes, slashing downtime and reducing replacement costs by minimizing components. Key features include precision temperature control, an improved and durable valve gate system, and high-quality German heating elements for maximum mould lifetime. The content details critical production characteristics, emphasizing the need for specific machinery, controlled high-temperature injection, rapid injection speeds due to PET's fast cooling, and precise mould temperature management to ensure optimal product transparency and quality. The manufacturer highlights its global reach and commitment to customer satisfaction through quality control and reliable service, including local warehousing for efficient sample testing.

PVC compound for pipe fitting is polymerized from polyvinyl chloride monomer (VCM). PVC material has the characteristics of non-toxic, anti-aging, acid and alkali resistance, and is very suitable for chemical pipelines. The mixture composed of a certain amount of solid additives (without plasticizers) added to the raw materials of polyvinyl chloride is called rigid polyvinyl chloride (UPVC).

PVC compound for pipe fitting cannot be hot-melted, and its sealing performance is not good; it is a rigid pipe material and has poor shock resistance; it often contains free chlorine, and its value itself is thermally stable.

In modern life, plastic building drainage pipes, water pipes and sewage pipes have been widely used, and polyethylene pipes are becoming the development direction of plastic pipes. PVC compound for pipe fitting was first used by Germany in 1936, and the world's first plastic water pipeline was laid in Britain in 1939. Since then, plastic pipes have developed rapidly, constantly replacing metal pipes or other traditional pipes. In the 1970s, the standardization and serialization of PVC compound for pipe fitting was realized internationally, which greatly promoted the production and application of plastic pipes in various countries.

PVC pipe fittings are made of PVC resin modified by chlorination. It not only preserves the excellent properties of many PVC materials, but also further improves these properties, allowing it to be used in a wider range of applications and has a longer service life. What is the production of PVC pip

The main application area of PVC pipe fittings is the supply of Level 1(60°C hot water) and Level 2(70°C hot water) under the design pressure of no more than 1.0 MPa. Industrial PVC pipes can be used for industrial high temperature transportation of corrosive liquids and gases up to a temperature of
