• 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.

• What Should We Pay Attention To in The Underwater Pelletizing Process of ABS?

  Regarding the production process of ABS resin, in industrial applications, the underwater strand pelletizing process is more common and more mature. However, the pelletizing system is not closed and there may be some uncertain factors that may lead to product contamination, such as the die plate of the industrial extruder, the water bath, etc.

• Important Components of Extruder—screw

  Perhaps many people have discovered that most of the extruders used in large-scale product production lines are single-screw structures, and very few are twin-screw structures. Upstream raw material suppliers, especially manufacturers of modified materials, functional masterbatches or color masterbatches, mostly use twin-screw extruders. Why is there such a difference? In this article, the editor will analyze and discuss the difference between single-screw extruders and twin-screw extruders.

• How To Use The Kneading Block of The Extruder

  Kneading blocks are components installed on the extruder screw. They are used in combination of two or more to mix and disperse materials and improve the mixing effect of the extruder. If you want to achieve a good mixing effect, it is important to choose the right kneading block.

• Working Principle of Twin Screw Extruder

  The structure of a twin-screw extruder is very similar to that of a single-screw extruder, but its working principle is very different. In a single-screw extruder, material transportation relies on the friction and viscous resistance of the material, so the residence time distribution is wider. In contrast, the material conveying of the twin-screw extruder relies on the positive displacement of the screw, so the residence time distribution is narrower. The raw materials of the twin-screw extruder are fed through the feed port by a metering feeder. Some additives (such as glass fiber) need to be added through the feed port in the middle of the barrel and transported to the die head by the screw. During this process, the movement of the material varies depending on the screw meshing method and the direction of rotation. This article will introduce the specific differences in their working principles from this perspective.

• Improve The "feeding" And "retracting" of Underwater Cutting To Achieve Stable Production of The Pelletizing System

  In the process of extrusion granulation, the feed system plays a key role in the force and coordination between the cutter and the template for the smooth operation of the unit. Let's take a look at the relationship between the feed hydraulic oil pressure and the retract balance system hydraulic oil pressure in the actual production process, and the practical effect after improvement.
