WOLJIA specializes in the design and manufacture of integrated extrusion and expansion lines for the production of Heat Shrink Tubing. Our comprehensive solutions include pelletizers, extruders, expanders, precision tooling, and a full range of auxiliary equipment.
Extrusion: The polymer mix is melted and extruded through a circular die to form a tube. Precise temperature control ensures uniform thickness and smooth surfaces. The extruded tube is cooled in water baths to solidify its initial shape.
At WOLJIA, we turn your requirements into high-performance reality. We provide the most suitable production solutions, custom-built to manufacture any heat shrink tubing you need. From single to tri-wall and thin to heavy wall, we ensure seamless, efficient production.
