High temperature melt pump is an indispensable equipment for conveying, pressurizing and metering high temperature and high viscosity polymer melt. Compared with other types of pumps, high temperature melt pump has compact structure, reliable operation, low energy consumption, high volumetric efficiency, small shearing effect on melt, stable flow rate under high viscosity and high pressure, and no outlet pressure fluctuation. The unique advantages of this pump and its key role in the process make it play an irreplaceable role in polyester production.

Whether the venting screw leaks material is directly related to the extrusion process, plastic properties, and the design of the screw and vent. Therefore, when manufacturers use venting extruders for production and processing, they must have a detailed understanding of the processing technology, resin characteristics, and equipment performance to ensure that the venting extruder can operate normally and stably.

Extruder screen changer, as the name implies, is a device used in plastic extrusion production lines. Its main function is to filter out impurities and particles in the melt to ensure the purity and consistency of the extruded material. The screen changer contains one or more filters, which can be replaced according to production needs to achieve a continuous filtering effect. In the plastic extrusion process, the presence of the screen changer effectively avoids production line interruptions and product quality problems caused by impurities.

Roots blowers and screw blowers have their own characteristics, and the choice should be based on the needs and scenario conditions of the specific application. Roots blowers are suitable for occasions with large flow and low pressure requirements, while screw blowers are more suitable for applications that require high pressure and stable airflow.

Plastic extruder is a common plastic mechanical equipment. In the daily operation of the extruder, various faults are inevitable, which affect the normal production of the extruder. Below, we will analyze the faults of the extruder in detail.

Bridging occurs when materials interlock or bond together, forming an arch above the container outlet. There are many factors that cause the "bridging" phenomenon: particle size, shape, specific gravity, humidity, static electricity, the cohesive strength and internal friction of a single particle will all have an impact on the "bridging" phenomenon. When this happens, the arched structure holds the rest of the contents in the feeder in place, preventing the remaining material from being discharged.

The plastic extruder pull bar granulation production line can be used for granulation of masterbatch, PE/PP+CaC03 materials, or recycling granulation of LDPE, HDPE, PP, ABS, PET and other raw materials.

Plastic granulator machines have revolutionized the way we handle plastic materials. They enable us to transform plastic waste and raw materials into manageable granules, reducing waste and contributing to sustainability. This guide aims to provide a comprehensive understanding of plastic granulators, their advantages, and their crucial role in promoting efficiency and sustainability.

PU is the general term for polyurethane, while TPU is a thermoplastic polyurethane elastomer. TPE is a polyolefin elastomer, while TPU is a polyurethane elastomer. TPU has much better wear resistance, and its hardness can be very low.

Plastic compounding refers to a process in which various additives and ingredients are mixed or compounded with plastic resins to create a customized material with specific properties. This process allows manufacturers to enhance or modify the characteristics of plastic materials to suit particular applications.
