The global plastic processing industry is facing growing demands for diversified raw materials, recycled plastic processing and high-efficiency production lines. Standard general-purpose screw barrels can no longer meet the customized production requirements of extruder and injection molding enterprises. Customized screw and barrel structural design has turned into a key factor that determines manufacturers’ production efficiency and finished product quality.
As a professional screw barrel manufacturer founded in 2019, NINGBO JIACHENG INDUSTRY CO., LIMITED focuses on tailor-made screw barrel solutions for global plastic and rubber machinery clients. Different raw materials such as PVC, HDPE, recycled plastic and engineering plastics carry distinct abrasion and corrosion characteristics. JIACHENG’s technical team cooperates closely with customers to adjust screw flight structure, barrel lining alloy formula and nitriding depth according to clients’ actual output speed, molding technology and material properties.
Compared with universal standard parts, customized bimetallic screw barrels designed for specific materials can boost production capacity by 15% to 30%, while effectively reducing wear loss and lowering long-term equipment maintenance costs. The company’s full set of CNC precision machining and bimetallic welding equipment supports flexible small-batch customization and mass bulk orders at the same time, serving downstream manufacturers producing plastic pipes, packaging films, plastic sheets and rubber profiles across Southeast Asia, Europe and South America.
Industry analysts point out that with the popularization of recycled plastic processing and new modified polymer materials, plastic machinery supporting parts suppliers with independent customized R&D capacity will occupy a larger share of the global market in the next 5 years. Strict pre-delivery full inspection on dimensional accuracy, wear resistance and anti-corrosion performance ensures JIACHENG customized screw barrels enjoy 2–3 times longer service life than ordinary standard products.
