PVC Extruder Production Line Features: For PVC resin, the extrusion production line enables a variety of processing operations:

1. Ordinary soft products can be extruded into cables, wires, and hoses using an extrusion line; by employing injection molding machines with various molds, one can produce shoe soles, slippers, a wide range of plastic sandals, as well as toys and automotive components, among other items.

2. PVC film. By mixing PVC with additives and then plasticizing the blend, a transparent or colored film of specified thickness can be produced using a three- or four-roll calender. This method is suitable for manufacturing calendered films. The material can also be cut and heat-sealed to produce raincoats, tablecloths, curtains, packaging bags, inflatable toys, and more. Wide‑width transparent films are used for greenhouses, plastic tunnels, and mulch films; while biaxially oriented films, owing to their heat‑shrinkable properties, are ideal for shrink packaging.

3. PVC foam products. During compounding, an appropriate amount of blowing agent is added to soft PVC to produce sheets, which are then subjected to foaming and molding to yield foam plastics. These materials are used for sandals, shoe insoles, foam slippers, and shock‑absorbing packaging, among other applications. Additionally, extruders can be used to produce low‑foam rigid PVC sheets and profiles, a novel building material that can serve as a substitute for wood.

4. PVC‑coated products. For coated artificial leather with a backing, the finished PVC coating is first applied to fabric or paper and then plastified at temperatures above 100°C; alternatively, PVC can be calendered with additives into a thin film and subsequently laminated to the backing. In contrast, unbacked artificial leather is directly calendered on a rolling mill to produce a soft, thin sheet of a specified thickness, which is then embossed with patterns. Artificial leather has a wide range of applications: it can be used to manufacture handbags, suitcases, book covers, sofas, and automotive seat cushions, and it can also be made into floor covering for use as a flooring material in buildings.

5. PVC paste resin. PVC emulsion or micro‑suspension resin is dispersed in a liquid plasticizer, where it swells and plastifies to form a plasticized sol. Stabilizers, fillers, colorants, and other additives are then incorporated, followed by thorough mixing and degassing to produce a PVC paste. This paste is subsequently processed into various products—such as coat hangers, tool handles, and Christmas trees—using techniques like casting, impregnation, or dip molding.

6. PVC transparent sheets. By adding impact modifiers and organotin stabilizers to PVC, followed by blending, plasticization, and calendering, a transparent sheet is produced. This material can then be thermoformed into thin-walled, transparent containers or vacuum‑formed into transparent sheets. It is an excellent packaging and decorative material, suitable for applications such as mooncake boxes and other vacuum‑formed packaging.

7. Rigid PVC sheets and boards. By adding stabilizers, lubricants, and fillers to PVC and then compounding the mixture, extrusion lines can produce rigid pipes of various diameters, profiled pipes, corrugated pipes, and other products, which are used for drainage pipes, potable water pipes, electrical conduit, or stair handrails, among other applications. Additionally, laminated and hot‑pressed calendered sheets can be manufactured into rigid boards of varying thicknesses; these boards can be cut into a wide range of custom shapes. Moreover, using PVC welding rods and hot air welding, one can fabricate chemically resistant storage tanks, ductwork, and containers, among other items.

8. Other applications of PVC. Extruders can be used to process PVC into rigid profiled materials for window and door assembly. In some countries, windows and doors assembled from rigid PVC profiles now share the market with wooden and aluminum products.
