The molding process of polyvinyl chloride pipes needs to start with pvc materials. First, the material formula can be divided into soft polyvinyl chloride and rigid polyvinyl chloride according to the different usage amounts of stabilizers, plasticizers, and lubricants. High-quality polyvinyl chloride is also called UPVC or RPVC, and soft polyvinyl chloride is also called SPVC.

According to the production of soft PVC materials or hard PVC as raw materials, PVC pipes are divided into soft pipes and hard pipes: rigid PVC pipes are made by mixing PVC resin with stabilizers, plasticizers, lubricants and other additives, and then use them. PVC mixed ingredients are extruded, or made into pellets first; soft PVC pipe is made of PVC resin and plasticizers and other additives with higher ingredients, and then made into granular PVC Material is extruded.

The big difference between these two types of pipes is that the rigid PVC pipes have excellent solvent resistance, corrosion resistance and insulation, and are key to the transportation of various liquids. Soft PVC pipes have excellent organic chemical reliability, insulation and excellent flexibility. The key is to replace rubber hoses, transport liquids and corrosive substances, and can also be used as insulating sleeves.

The following is the molding process of PVC pipe: Production process: PVC material resin + preservative preparation in advance → mixing → feeding → mandatory feeding → conical double single-screw extruder → extrusion die → shaping sleeve → spraying vacuum pump shaping box →Bubble immersion refrigeration water storage tank→Color printer→Crawler tractor→Automatic cutting machine with knife→Pile pipe support→Quality inspection and packaging.

Among them, the production process raw materials + preservatives can be purchased from PVC material manufacturers immediately. Zhejiang Jinlida Enterprise is mainly a technical professional enterprise that produces and manufactures this product. Its PVC formula library has more than 8,000 kinds, which can provide customers with more technical and professional technical services.
