Zhejiang Yujin Plastic Machinery Co., Ltd.
Company introduction
描述
As a high-tech enterprise integrating R&D, manufacturing, and sales, Yujin focuses on injection molding under extreme operating conditions, dedicated to the innovative R&D and intelligent manufacturing upgrades of high-precision screw and barrel assemblies.






Forward-Looking Technology · Precision Solutions
Facing the rapid iteration of new materials and increasingly complex operating conditions in the plastics industry, we continuously monitor global trends in injection molding. Leveraging profound technical expertise, we provide customized solutions tailored to material properties. From polymer rheology analysis to screw structure simulation optimization, Yujin has built a process database covering 200+ specialized materials.
Intelligent Manufacturing · Quality Excellence
In recent years, the company has invested in advanced CNC equipment such as five-axis machining centers and screw root grinding machines. By adopting German and Japanese design philosophies and precision machining techniques, implementing lean production management with full staff participation, and establishing a comprehensive quality control system, we ensure critical dimensional accuracy within ±0.01mm and extend product service life by over 80% compared to industry standards. A digital management platform enables full lifecycle traceability from raw materials to finished products.
Innovation-Driven · Value Co-Creation
Guided by customer pain points, Yujin has achieved breakthroughs in four core areas:
1.Optical-grade transparent product yield increased to over 97%.
2.Screw and barrel assemblies for high-glass-fiber (50%+) V0/halogen-free flame-retardant applications deliver over 1 year of service life with 
ultra-wear/corrosion resistance.
3.Screw and barrel assemblies for high-glass-fiber (50%+), MIM, and ultra-wear applications exceed 1 year of service life.
4.Super-corrosion-resistant screw and barrel assemblies for fluoroplastics (PFA, PVDF) injection molding achieve over 3 years of service life.
Relentless Dedication · Craftsmanship in Manufacturing
With over a decade of technical refinement, Yujin products have served 6,000+ clients across 30+ countries and regions, earning acclaim in automotive, 3C electronics, biomedical, and optical industries. Moving forward, we will deepen our precision intelligent manufacturing system with a global vision, driving product excellence to create greater value for customers.
