In recent days, a cold wave swept across many areas, with temperatures plummeting to -10 degrees Celsius. Heavy snow blanketed outdoor operations in layers of ice. Despite these extreme weather conditions, our frontline colleagues braved the wind and snow, battling the bitter cold to complete the container loading of two sets of ABS co-extruded sheet equipment, ensuring the equipment's timely shipment to Tanzania. Their dedication and commitment have written a chapter of winter struggle.

Recently, our PA (Nylon) sheet production equipment has completed commissioning. After multiple rounds of process testing and certification by the customer, the equipment operates stably, and the products meet standards, successfully completing the delivery task. In the initial commissioning phase, technicians conducted a comprehensive inspection and calibration of the entire production line, focusing on monitoring the correctness of every action of the sheet production equipment. The equipment underwent an hour of idle operation to ensure stable operation.

The molybdenum disulfide nylon extrusion equipment is a sheet extrusion production line specifically designed for PA6/PA66 modified with molybdenum disulfide. The equipment requires a dedicated, wear-resistant screw with a temperature control accuracy of ±1℃, and is suitable for processing temperatures of 220-260℃.

The core reason for defects in ABS sheet extrusion line: 1. Excessive or uneven cooling rate: A large temperature difference between the upper and lower surfaces of the sheet prevents the release of internal stress. 2. Excessive tension in the traction machine: This causes excessive longitudinal stretching, leading to sheet shrinkage and warping.

Core Causes: 1. Insufficient raw material drying: This easily leads to bubble formation during extrusion; uneven mixing of moisture and melt results in silver streaks. 2. Localized overheating of the extruder barrel: Excessive temperature causes degradation of the ABS molecular chains, producing small volatile molecules that form surface pitting. 3. Impurities or excessive moisture in recycled material: Failure to re-dry recycled material or the presence of dust after pulverization exacerbates defects.
