Jiangsu Hongkai Plastic Technology Co., Ltd. is one of top ten ABS core reels manufacturers and suppliers in China. ABS core reels are manufactured using advanced injection molding techniques. During production, carefully selected ABS (acrylonitrile-butadiene-styrene copolymer) raw material is injected into precisely engineered molds. Through meticulous control of critical parameters such as injection temperature, pressure, and duration, the material fills the mold uniformly, cools, and solidifies, ultimately forming core tubes with specific structural integrity and dimensional accuracy. This injection molding process ensures the cores exhibit high precision, dimensional consistency, and superior surface quality, meeting the demands of various high-end applications.
Within the industry, ABS core reels are categorized into four common specifications based on the inner diameters of their inner and outer tubes: “3 inner, 6 outer,” “3 inner, 8 outer,” “6 inner, 10 outer,” and “3 inner, 10 outer.” For clarity to non-industry professionals, these specifications are detailed below:
“3-inch inner, 6-inch outer” specification: This core tube features an inner tube ID of 3 inches and an outer tube ID of 6 inches. This dimensional design provides optimal support space for both inner and outer films in specific winding scenarios, ensuring stability and flatness during the winding process.
“3-inch inner, 8-inch outer” specification: The inner tube diameter remains 3 inches, while the outer tube diameter increases to 8 inches. Compared to the “3-inch inner, 6-inch outer” specification, it accommodates larger external film winding requirements. It ensures normal winding of the inner film while providing ample winding space for the outer film.
These four specifications of ABS core reels, featuring precise dimensional design and reliable injection molding processes, are widely used in the winding applications of various films such as lithium battery separators, optical films, copper foil, and aluminum foil. They provide robust support for enhancing winding quality and production efficiency.
