As the core power source of the twin-screw extruder, the operational stability of the main motor directly determines the production efficiency, product quality, and service life of the extruder. Under long-term high-load and continuous operation conditions, the main motor is prone to various faults affected by multiple factors such as process parameters, operating specifications, and…

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…
