• What To Do If The Die Hole of Underwater Pelletizing Is Clogged? Do These Three Things To Reduce The Frequency of Machine Cleaning

  Compared with strand pelletizing, underwater pelletizing has the advantages of better pellet quality, higher degree of automation and lower cost. However, compared with less sensitive commodity resins such as polyethylene, polypropylene or polystyrene, the risk of mold freezing is greater when producing engineering resins such as those mentioned in the previous paragraph.

• [Required Course for Extrusion Production of Corrosive Materials] Screw & Barrel

  Corrosive, abrasive, and high-temperature resins can inadvertently degrade screws and barrels. Certain engineered materials, thermoplastic elastomers, and newly developed biopolymers often create corrosive conditions that rapidly degrade equipment. Reinforcement materials such as glass fibers, balls, and other fillers and additives are abrasive and can also cause damage to equipment, especially feed screws and barrels.

• Structure And Working Principle of High Temperature Melt Pump

  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.

• Introduction To PVC Mixing Technology

  In the PVC (polyvinyl chloride) processing technology, mixing technology plays a vital role as the first process in the production of PVC products. However, many companies often do not pay enough attention to the mixing process, which leads to misunderstandings among workers about mixing technology, thinking that it is enough to just mix the materials evenly. This article will introduce the role, principle and process of PVC mixing in detail to help readers fully understand PVC mixing technology.

• Causes And Solutions for Material Leakage From Vacuum Port of Extruder

  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.

• Basic Concepts And Working Principles of Extruder Screen Changers

  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.

• The Main Causes And Countermeasures of Gear Transmission Noise

  Traditionally, the two main factors for measuring gear transmission performance are load capacity and fatigue life, and transmission noise and transmission accuracy are often ignored. With the promulgation of ISO14000 and ISO18000, the importance of controlling gear transmission noise has become increasingly apparent, and industrial development and demand have increasingly stringent requirements for transmission errors of high-precision equipment (gear transmission backlash). The currently known factors that cause gear noise can be roughly analyzed from several aspects, including design, manufacturing, installation, use and maintenance.
