This article explains the differences between mold temperature controllers (MTCs) and industrial chillers in plastic manufacturing. Both devices regulate temperature, but their principles and applications differ. MTCs provide precise heating and stable temperature control for molds, enhancing product quality and production efficiency in processes like injection molding, blow molding, and extrusion. Industrial chillers offer rapid cooling and constant-temperature water for equipment or materials that require heat removal. Understanding their working principles, control accuracy, and appropriate usage scenarios helps manufacturers optimize production, improve product quality, and reduce energy consumption.

This article introduces four essential screw-cleaning methods used in modified plastic production, especially for twin-screw extruders. It explains the working principles, operating procedures, advantages, and limitations of resin purging, mechanical disassembly cleaning, flame cleaning, and water-based hydrodynamic cleaning. By comparing their effectiveness, risks, and application scenarios, the article helps manufacturers choose the most suitable method for different materials and contamination levels. It also highlights the importance of proper operation, regular maintenance, and standardized cleaning processes to improve product quality, reduce defects, and extend extruder service life.

This article provides a complete maintenance guide for plastic pelletizing machines, covering daily inspections, periodic servicing, and emergency troubleshooting. It explains how proper lubrication, temperature control, electrical checks, and routine cleaning can prevent common failures such as material blockage, motor overheating, pellet contamination, and screw wear. The guide also outlines monthly, quarterly, and annual maintenance tasks for the hydraulic system, screw and barrel, gearbox, and electrical components. With practical steps for handling sudden issues like jamming, impurity-contaminated pellets, and overheating motors, the article helps manufacturers extend machine lifespan, reduce repair costs, and ensure stable, high-quality pellet production.

This article provides a practical guide to solving common problems in plastic pelletizing, including long pellets, fused pellets, black spots, and discoloration. It explains the root causes of each issue—such as unstable strand feeding, insufficient cooling, equipment contamination, improper temperature control, and poor mixing. The article also offers effective solutions, including optimizing cooling systems, maintaining cutter blades, improving material handling, thoroughly cleaning equipment, and adjusting extrusion temperatures and screw configurations. By controlling every step from raw material to finished pellets, manufacturers can enhance pellet quality, reduce waste, and improve production efficiency.

The color masterbatch polishing machine is a specialized device designed to refine the surface of color masterbatch granules used in plastic manufacturing. It operates through high-speed friction and grinding to remove surface irregularities, producing smooth and glossy pellets. This process enhances the dispersion and visual quality of masterbatches in plastic products. By improving surface finish, increasing production efficiency, and reducing labor costs, the polishing machine plays a vital role in enhancing product appearance, performance, and overall competitiveness in the plastic extrusion and processing industry.

The internal mixer single-screw hot-cut carbon black pelletizing machine combines mixing, extrusion, and hot-cutting to produce uniform carbon black pellets. It ensures efficient dispersion, stable extrusion, and consistent pellet size, making it ideal for rubber, plastic, and industrial additive applications.

This article explains how to enhance both the efficiency and product quality of a twin-screw extruder. Efficiency can be improved by increasing screw speed and torque, optimizing screw geometry, enlarging free volume, and strengthening the gearbox design. Product quality depends on precise plasticizing system design, including modular screw segmentation, accurate geometric configuration, and strong self-cleaning performance. Through mechanical optimization and digital 3D modeling, manufacturers can achieve higher productivity, stability, and uniform polymer output.

This article compares extrusion and pelletizing equipment used for TPE, TPR, TPU, TPV, and silicone rubber materials. While all elastomer pelletizing lines share core components—such as twin-screw or single-screw extruders, cooling systems, and pelletizers—each material has specific equipment needs. TPU requires precise temperature and moisture control, TPV demands high-torque twin-screw extruders for dynamic vulcanization, and silicone uses specialized extruders with vacuum degassing and curing systems. Overall, process optimization and tailored screw configurations are key to achieving high-quality pellets and efficient production.

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.

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.
