As one of the most widely used inorganic filling materials in plastic processing, calcium carbonate filler masterbatch is widely used in the production of various plastic products such as polyethylene and polypropylene due to its advantages of low cost and significant modification effect. It can effectively reduce raw material costs and improve the rigidity and…

The core of calcium carbonate filled masterbatch production is to achieve uniform dispersion, sufficient plasticization and stable molding of calcium carbonate powder and carrier resin. As a key core equipment, the twin-screw extruder’s structural design, performance parameters and auxiliary configuration must accurately adapt to the material characteristics of calcium carbonate (high wear resistance, easy agglomeration,…

The heating system of a twin-screw extruder is a core unit ensuring the plasticization and melting quality of materials. Its components include heating elements, temperature control equipment, and auxiliary parts, with significant price differences influenced by material, specification, purchase volume, brand, and other factors. Based on quotes from mainstream suppliers in the current market (January…

The heating system of a twin-screw extruder is the core guarantee for the plasticization quality of materials. It mainly consists of heating elements (heating coils, heating rods), temperature sensors (thermocouples/PT100), temperature control instruments, solid-state relays (SSR), electrical circuits, and cooling auxiliary devices. Faults are mostly manifested as no temperature rise, slow temperature rise, temperature runaway,…
