Plastic Processing Industry
Pelletizing: During the plastic pelletizing process, the melt pump can precisely control the flow rate and pressure of the plastic melt. For example, when producing pellets of polyethylene (PE), polypropylene (PP), etc., the melt pump can ensure that the melt is extruded uniformly through the die, making the pellet size more uniform and the shape more regular. This is crucial for the processing performance and quality stability of subsequent plastic products.
Mixing: When it is necessary to mix different types of plastics or additives, the melt pump can ensure that each component is mixed evenly in proportion. For instance, when producing engineering plastic alloys (such as PC/ABS alloys), different plastic melts are transported by the melt pump and fully mixed at the mixing head, avoiding differences in product performance caused by uneven mixing.
Extruding Sheets, Pipes, Films and Profiles: When extruding sheets for manufacturing plastic packaging materials (such as PVC sheets for food packaging), the melt pump can provide a stable supply of melt and ensure the uniform thickness of the sheets. For pipe production (such as PE water supply pipes, PPR hot water pipes), it can ensure the accuracy of the inner and outer diameters of the pipes as well as the consistency of the pipe wall thickness. In terms of film production (such as agricultural films, packaging films), it helps to control the thickness and flatness of the films. During the extrusion of profiles (such as plastic door and window profiles), the melt pump can make the dimensions of each part of the profile precise and ensure good surface quality.
Rubber Industry
Tire Production: In tire manufacturing, it is necessary to transport high-temperature rubber melts to different processing stations. The melt pump can accurately transport the rubber melt into the molding dies for the tread, sidewall and other parts of the tire. For example, when manufacturing high-performance radial tires, it ensures that the rubber melt enters the vulcanization die at a stable flow rate and pressure, thus guaranteeing the quality and performance of the tire, such as wear resistance, fatigue resistance and grip.
Rubber Hose Production: For the production of various rubber hoses (such as automotive rubber hoses, industrial rubber hoses), the melt pump can uniformly extrude the rubber melt into the mold, making the inner diameter, wall thickness and other dimensions of the rubber hose meet the requirements and ensuring the quality stability of the rubber hose along its entire length.
Chemical Fiber Industry
Polyester Fiber Production: During the production process of polyester (PET) fibers, from the synthesis of polyester melt to fiber spinning, the melt pump plays a key role. It transports the polyester melt from the reactor to the spinning assembly, precisely controls the flow rate and pressure of the melt, and ensures the stability of the spinning process. For example, when producing fine-denier polyester fibers for high-end clothing fabrics, the melt pump can ensure that the melt passes through the spinneret uniformly, so that the fineness, strength and other indicators of the fibers meet the requirements.
Nylon Fiber Production: During the manufacturing process of nylon (such as PA6, PA66) fibers, the melt pump is also used to transport and meter the nylon melt. In the high-speed spinning process, the precise metering function of the melt pump can ensure the uniform linear density of the fibers, thereby improving the quality and spinnability of the fibers.
Other Fields
Resin Industry: During the processing of thermosetting resins such as epoxy resins and phenolic resins, the melt pump can be used to transport resin melts, ensuring the uniform distribution of resins in the molding process (such as injection molding, compression molding, etc.), and improving the quality and performance of products. For example, when producing electrical insulation parts made of epoxy resin, the melt pump helps to evenly fill the mold with the resin, ensuring the consistency of the insulation performance.
Hot Melt Adhesive Industry: During the production and application of hot melt adhesives, the melt pump is used to transport and distribute hot melt adhesive melts. For example, in an automated packaging production line, the hot melt adhesive is accurately transported to the glue gun for operations such as sealing cartons, ensuring the accurate amount of glue used and firm bonding.
Medical Plastic Industry: During the production of medical plastic products (such as syringes, infusion bags, etc.), the melt pump can precisely control the transportation of plastic melts, ensuring the dimensional accuracy and quality stability of the products. For some medical plastics with extremely high requirements for purity and quality (such as polycarbonate used for manufacturing the housing of hemodialysis machines), the melt pump can also reduce the pollution and performance changes of the melt during the transportation process.
