As sustainability becomes increasingly important, turning waste materials into usable resources has become a question many companies should consider. Through a series of precise processing steps, SBS transforms the PET materials from discarded zippers into regenerated resources. Now, let’s take a closer look at the journey of how waste zippers are brought back to life.

Precise classification: Through careful classification and precise proportioning of waste zippers, monofilaments broken teeth and other materials, the metal materials inside can be precisely removed, opening the door to recycling.

Crushing processing: A powerful crusher breaks the zipper into small pieces whose shape and volume are conducive to subsequent processing.

Kneading and pelletizing: Unique machinery and process parameters cooperate to rotate and squeeze the fragments into high-density pellet, solving the problem of loose materials and ensuring smooth melting and transformation.

Melt extrusion: The screw extruder, melts the pelletized raw materials at high temperature, accurately controls multiple parameters and stably extrudes specific flow channel materials for molding and granulation.

Forming and granulation: Water cooling and air cooling are combined to quickly cool and shape the product. The granulator cuts the shaped product into uniform and regular particles.

Pre-crystallization: Under precise temperature control, from disordered to ordered arrangement and combination, arable molecular structure foundation is built to help improve quality.

Thickening: Advanced technology entangles the molecular chain reaction and improves the key performance of the product.

By recycling and reusing discarded zippers, SBS not only reduces resource waste but also takes a meaningful step toward greener practices. Committed to environmental responsibility, SBS aims to help build a more sustainable and harmonious future.
