CSSSLD PVC profile extrusion overseas market for light cover

New developped PVC extrusion profile for power socket rail Extrusion is done by squeezing the metal in a die by using a mechanical or hydraulic press. Extrusion is capable of producing compressive and shear forces in the stock material. As tensile is not produced, this makes very high deformity a possibility without actually tearing the metal.

Plastic extrusion process How it works?Advantage / DisadvantagePlastic profile extrusion is a molding method in which plastic resin is continuously melted, pushed through a die with the desired cross-section (a “profile”), and then pulled through a water bath until fully cooled. The formed plastic can then be fabricated and either cut into multiple parts or wound as a single part.There are four zones through which the material moves through:• Extruding zone, in which resin is melted, additives such as talc, foaming agents, glass, or color may be added, and the material is forced through the extruder die assembly. • Sizing zone, in which a pull vacuum is used to prevent collapse and control warpage as the plastic hardens. This step is only used in profiles with one or more hollows.• Cooling zone, in which the plastic is ran through cool water tanks until it hardens completely.• Processing zone, in which the extrusion is measured for quality and processed in-line with the application of adhesion promoters, tape, slip coating, and/or ink-jet printing. This step is optional.• Cutting zone, in which the extrusion is cut to desired lengths or spooled.Compared to other forming and molding processes, extrusion has a number of advantages and disadvantages:ADVANTAGES•High production rates•Low cost tooling•Short tooling lead times•Many types of raw materials•Lowest cost conversion processes for plastics•Can combine multiple durometers in a single extrusionDISADVANTAGES•Only provides a uniform cross sectional shape•Surface area is not class A for all materials•Tolerances are greater than injection moldSecondary operations required to add a third

The raw materials largely determine the quality of the electronic plastic components. If being in their natural and excellent state, the raw materials used in the production process can ensure a smoother production process in the later phase and a higher qualification ratio of the finished products. Also, they play an important role in pricing the products. This leads to a fact that many manufacturers now do their endeavor to carefully choose cost-effective raw materials. Changshu shunda plastic products factory is a technologically advanced enterprise which mainly produces Plastic extrusion profile. plastic injection is one of CSSSLD's multiple product series. The production facilities used in CSSSLD extruded plastic channel are newly introduced with high efficiency. It will be processed under a welding machine, laser machine, automatic spray-painting machine, and surface polishing machine. It comes in a seemingly limitless range of colors. By years of accumulation, CSSSLD has established perfect quality assurance and managing system to assure plastic injection's quality. This product provides flame retardancy to some extent.We are putting efforts into a sustainable future. We are working hard to reduce production waste and CO2 emissions to minimize our footprint.
