Have you solved these problems encountered in the production process of TPE extrusion materials? 1. Rough surface of molded product 2. Scaling 3. Unstable extrusion volume 4. Deformation 5. Stripes

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.

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.

Masterbatch is the most common plastic coloring method and is widely used in the plastic processing industry. Dispersion is one of the most important performance indicators of masterbatch. Obviously, dispersion has a vital impact on the quality of plastic products.

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.

The plastic granulator is a kind of equipment commonly used to produce plastic granules. The temperature regulation of each area is very important for product quality and production efficiency. The following will introduce in detail the temperature regulation method of each area of the plastic granulator.

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.

CaCO3 powder, also known as calcium carbonate powder, is often added to plastic pellets for the following reasons:1. Reduce costs 2. Improve mechanical properties 3. Density Adjustment 4. Improved processing properties 5. Environmental benefits 6. Improve the heat resistance of plastic products 7. Improve the light diffusion of plastics 8. It can make the product have some special properties

The performance parameters of calcium carbonate have such a great influence on the filling masterbatch! 1. Calcium content 2. Whiteness and hue 3. Water and volatile matter content 4. Particle size distribution 5. Particle shape 6. Content of other components

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.
