1、Plastics industry
It is widely used in the plastic extrusion molding process. For example, in the production of plastic pipes, the melt pump is installed between the extruder and the die head. It can accurately control the flow of plastic melt to ensure that the pipe wall thickness is uniform. In the production of PVC (polyvinyl chloride) pipes, for example, where the processing properties of the PVC material are sensitive to flow and pressure, the melt pump delivers the melt in a stable manner and improves the quality of the pipe.
For the production of plastic films, such as PE (polyethylene) film, melt pumps allow the melt to be evenly distributed across the extruder's die opening, ensuring consistent film thickness. This is very critical in the production of packaging film, agricultural film, etc., to help reduce the rate of defective products.
2, the rubber industry
In the processing of rubber products, especially in the extrusion molding of rubber mixing has important applications. For example, in the production of automobile tire tread rubber, melt pumps can be mixed rubber melt accurately transported to the extrusion mold, to ensure the dimensional accuracy and quality stability of the tread rubber.
For the production of rubber seals and other products, melt pumps can help control the flow of rubber melt to ensure that the dimensional accuracy and performance of the seals, because the seals require high dimensional accuracy, accurate flow control can effectively improve the product qualification rate.
3, Chemical fiber industry
In the chemical fiber spinning process, the melt pump is one of the key equipment. Polyester fiber (PET) production, for example, the melt pump will polyester melt uniformly transported to the spinning component. It stabilizes the spinning pressure, making the spun fiber uniform in thickness and also positively affecting the fiber's strength, luster and other properties.
In the production of nylon, acrylic and other chemical fibers, melt pumps also play a role in accurately controlling the flow of the melt to ensure that the quality of the fiber meets the requirements to meet the textile industry for the strict requirements of fiber quality.
