Twin-screw extruders are core equipment in industries such as plastics, food, and chemicals. The quality and cost of their spare parts directly affect production efficiency, product quality, and operation and maintenance costs. This report classifies key spare parts by core functional modules, details their market price ranges, and provides corresponding service life recommendations based on…

In the global plastic processing industry, cost control and performance optimization have always been the core demands of manufacturers. Sodium sulfate filler masterbatch and high filling compounds, as high-cost-performance inorganic additive solutions, have been widely used in PE, PP, EVA and other polymer materials. They not only significantly reduce raw material costs but also improve…

Color masterbatch is a new type of specialized coloring agent for polymer materials. It is composed of three basic elements: pigments, carriers, and additives. Its coloring power is higher than that of the pigment itself. The basic components of color masterbatch 1. Pigments Pigments are divided into organic pigments and inorganic pigments. Common organic pigments…

Polyethylene terephthalate (PET) color masterbatch plays a vital role in modern plastic manufacturing, widely used in bottles, films, fibers, and injection molding products. Producing high-quality PET color masterbatch requires careful control over raw materials, production processes, and machine configurations. 1. Understanding PET Color Masterbatch: Raw Materials and Formulation 1.1 PET Carrier Resin Selection The carrier…

In recent years A new type of plastic compounding and pelletizing equipment — the triple-screw extruder — has emerged in the traditional plastic modification market. Compared with the conventional twin-screw extruder, the triple-screw extruder is not merely “one more screw.” It provides significant improvements in dispersion efficiency and output capacity in certain application areas. Classification of…
