This article discusses how to increase the output of a twin-screw extruder by optimizing the screw configuration. It explains how improvements in feeding efficiency, melting performance, side feeding design, mixing quality, and pressure build-up can enhance extrusion productivity. By adjusting the screw elements, such as conveying and kneading blocks, manufacturers can achieve higher throughput, better material dispersion, and more stable processing without changing the extruder size.

Breathable film masterbatch, produced mainly with polyethylene and additives through extrusion processes, is widely used in medical, packaging, and construction fields. With excellent breathability, stable quality, and bright colors, it plays a key role in manufacturing breathable films. Its production involves raw material mixing, melt blending, hot-melt extrusion, and cooling. As demand grows, factories are focusing on technological innovation, eco-friendly materials, and market expansion to enhance competitiveness.

Laboratory extruders are compact, high-precision extrusion machines designed for material research, small-batch production, and educational use. Compared to industrial extruders, they feature flexible modular design, precise control systems, and lower throughput, making them ideal for polymer modification, masterbatch development, reactive extrusion, and pilot-scale testing. With screw diameters typically ranging from 12 to 45 mm and output capacities of 0.25–150 kg/h, lab extruders provide critical data for process optimization, scale-up validation, and innovative material development across plastics, pharmaceuticals, and food industries.

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.

Care and keeping your compounding extruder in good condition is critical to the performance and longevity of the equipment. A compounding extruder is a key piece of equipment used to mix and process materials such as plastics, and it plays an important role in the production process.
