• 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.

• There Are Higher Requirements for The Production Efficiency And Product Quality of Twin-screw Extruders. Where Can We Start To Optimize Them?

  As the manufacturing and processing technology of twin-screw extruders becomes better and better, it not only has to perform tasks such as feeding and plasticizing, but also has some requirements such as dehydration and drying. In order to better meet the different needs of users, the twin-screw extruder must continuously improve its working efficiency, and also find ways to improve the quality of the products produced.

• Why Is The Extrusion Temperature Higher Than The Melting Point?

  In summary, although the resin begins to melt at its melting point, in order to ensure a smooth extrusion process and produce high-quality films, it usually needs to be processed at a temperature higher than the melting point.

• What Is The Difference between Roots Blower And Screw Blower?

  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.

• Application of Loss-in-Weight Scale in Plastic Modification Operation

  The loss-in-weight scale uses the weighing hopper and the entire feeding mechanism as a scale body for weighing. As the material flows out of the loss-in-weight scale, the control system collects the weight signal of the scale body at a high speed and high frequency to obtain the weight reduction of the material in the weighing hopper per unit time. Then, through TRUSTAR's unique filtering and optimization processing, the actual flow rate of the loss-in-weight scale is obtained. At the same time, the control system compares this feeding speed with the preset given speed, and calculates the comparison result and feeds it back to the feeding mechanism of the loss-in-weight scale to automatically correct the feeding speed of the feeding mechanism, forming a closed-loop control, so that the actual flow rate is infinitely close to the given flow rate, thereby meeting the control requirements.
