Advantages of PVC profile equipment

PVC profile equipment is a machine for making PVC profiles. PVC profiles are PVC products for industrial and daily use extruded at high temperature after adding various functional additives from PVC resin. According to performance, it can be divided into hard and soft. Rigid PVC profiles are mostly used in construction, such as making PVC doors and windows, PVC floors, PVC pipes, etc.; soft PVC profiles are used for PVC hoses, power transmission cables, etc. PVC profiles added with functional additives have anti-aging, anti-ultraviolet, corrosion resistance, high strength, low price, good heat preservation and heat insulation performance, and can partially replace aluminum profiles, steel materials, etc., and have lower pollution than aluminum profiles.

PVC profile equipment extrusion molding, also known as extrusion molding, is mainly suitable for the molding of thermoplastics, but also for the molding of some thermosetting and reinforced plastics with better fluidity. The molding process is to use a rotating screw to extrude the heated and melted thermoplastic material from a die with the required cross-sectional shape, and then it is shaped by a sizing device, and then cooled and solidified by a cooler to become the required cross-sectional shape. product. The machine is equipped with a quantitative feeding device, so that the extrusion volume can be matched with the feeding volume and ensure the stable extrusion of the product. Due to the characteristics of the conical screw, the feeding section has a larger diameter, and the heat transfer area and shear speed of the material are relatively large, which is conducive to the plasticization of the material. The screw diameter of the metering section is small, which reduces the heat transfer area and the melt. The shear speed enables the melt to be extruded at a lower temperature. When the screw rotates in the barrel, it plasticizes the PVC mixture and pushes it to the head, so as to achieve compaction, melting, mixing and homogenization; and to achieve the purpose of exhaust and dehydration.

PVC profile equipment has low cost, simple operation, easy control of the process, easy to realize continuous automatic production, high production efficiency, uniform and dense product quality, and various cross-sectional products or semi-finished products can be formed by changing the die of the machine head. In the field of product design, extrusion molding has strong applicability. The types of extruded products include pipes, films, rods, monofilaments, flat belts, nets, hollow containers, windows, door frames, plates, cable cladding, monofilaments and other profiled materials.
