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.

The main methods for implementing grafting reactions include solution method, melting method, solid-phase method, and radiation grafting method.

Double-stage extruder （SP Series） and twin-screw extruder (TSE Series) are the main product series of Kairong Group & Haisi Extrusion. There are big differences between these two models.

Injecting TPE materials requires strict control of temperature, pressure, injection speed, and other process parameters to ensure the production of high-quality finished products. Meanwhile, appropriate mold design and equipment maintenance are also key factors to ensure successful processing of TPE.

PE has excellent mechanical processing performance, but its surface is inert and non-polar, resulting in poor printability, dyeing, hydrophilicity, adhesion, anti-static performance, and compatibility with other polar polymers and inorganic fillers. In addition, its wear resistance, chemical resistance, environmental stress cracking resistance, and heat resistance are poor, limiting its application range. Modification is needed to improve its performance and expand its application field.
