For PVC resin, a variety of  pvc plastic extrusion profiles  can be made using an extruder: (I) General soft products can be extruded into cables, wires and hoses through an extruder; using injection molding machines with various molds, it can be made into soles, slippers, various plastic sandals, toys, and car accessories. (2) PVC film After PVC is mixed with additives and plasticized, a three-roll or four-roll calender can be used to make a transparent or colored film with a specified thickness. This method can be used to process the rolled film. You can also cut and heat-process raincoats, tablecloths, curtains, bags, inflatable toys, etc. Wide transparent films can be used in greenhouses, plastic greenhouses and mulching films; biaxially stretched films can be used for shrink packaging due to their thermal shrinkage. (3) PVC foam products When soft PVC is mixed, a suitable amount of foaming agent is added to form a sheet, which is then foamed to form foam plastic, w...

The principle of injection molding is to add granular or powdered raw materials to the hopper of the injection machine. The raw materials are heated and melted into a flowing state. Pushed by the screw or piston of the injection machine, they enter the mold cavity through the nozzle and the casting system of the mold , Harden and set in the mold cavity. Factors affecting the quality of injection molding: injection pressure, injection time, injection temperature. Plastic Injection Profiles Plastic injection profiles supplier  believes its advantages: Short molding cycle, high production efficiency, easy to achieve automation; can form plastic parts with complex shapes, precise dimensions, and metal or non-metal inserts; stable product quality; wide range of applications. Disadvantages: The price of injection equipment is high, and the structure of the injection mold is complicated. High production cost, long production cycle, not suitable for the production of single...

The  plastic extrusion supplier  will share with you: the process of plastic extrusion molding pipes as follows: According to the plastic tube molding material formula requirements, measure the various raw materials into the mixing chamber of the mixer, stir at high speed, Various raw materials are mixed uniformly; the mixed high-temperature materials are mixed and cooled (generally the material temperature should be lower than 40 ℃) and then put into the hopper of the extruder; Inside the barrel; as the screw rotates, the raw material is forced to be pushed forward of the barrel. Due to the resistance of the filter screen, perforated plate and molding die in front of the barrel, and the gradual reduction of the screw thread volume, the resistance of the raw material in the barrel to move forward increases with the increase of the amount of material in the front. That is, the pressure of the raw material is increasing; at the same time, the raw material is affected by ...

Plastic extrusion supplier  to share with you: extrusion molding is currently one of the common plastic molding method, applies to all thermoplastics and some thermosetting plastic, forming can be all kinds of plastic tubing, rod, plate, wire and cable and profiled material etc., Custom Pvc Plastic Extrusion Profile Characteristics of plastic extrusion process:  plastic extrusion , Thermoplastic parts after leaving the nose die, plastic parts should be immediately shaped and cooled, otherwise plastic parts under the action of gravity deformation, sag or distortion phenomenon.In most cases, the shaping and cooling are carried out at the same time, only in the extrusion of a variety of rod and tube materials, there is an independent sizing process, and extrusion of thin die, monofilaments, etc. do not need the shaping, only through cooling. Extruding sheet and sheet, and sometimes through a pair of roller pressing, but also shaping and cooling effect.The shaping me...
