Established 15 years ago, TOKIN has grown into a reliable manufacturer specializing in high-quality components for plastic injection molding and extrusion machines. Our core product range includes precision screw barrels, nozzles, and various molding parts, all designed to deliver consistent performance, extended service life, and excellent compatibility with major machine brands.We operate a modern production facility equipped with advanced CNC machining centers and precision lathes, enabling us to maintain tight tolerances and superior surface finishes. Every screw and barrel undergoes specialized surface treatments — including bimetallic alloy lining for outstanding wear and corrosion resistance, and hardening processes (Nitriding, through-hardening, etc.) — to handle highly abrasive compounds, filled materials, and demanding production environments. Quality is at the foundation of everything we do. From raw material selection through final inspection, each component is carefully controlled to meet international standards. To give our customers complete confidence, all products are backed by a full 12-month quality guarantee.Over the past decade and a half we have built long-term partnerships with plastic processors in packaging, automotive, household goods, pipe/profile extrusion, and many other industries. We offer both standard replacement parts and custom-engineered solutions tailored to specific resins, throughput targets, and machine specifications.TOKIN combines experienced craftsmanship, modern manufacturing technology, and a strong commitment to customer satisfaction. We aim to help our partners reduce downtime, improve output quality, and lower long-term operating costs.We welcome inquiries from manufacturers worldwide — contact us to discuss how our screw barrels, nozzles, and molding parts can support your production goals.
