What Best Plastic Machinery Co. does

Best Plastic Machinery Co. (legal entity: Zhoushan Jintang Best Plastic Machinery Co., Ltd.) is a privately held Chinese manufacturer of screw barrels and related wear components for plastic and rubber processing machinery, headquartered in Ligang Industrial Zone, Jintang Town, Dinghai District, Zhoushan, Zhejiang Province. The company was founded around 1993-2000 and operates with 51-100 employees, marketing "over 20 years" of production experience in screws and barrels. Its product portfolio spans single screw barrels, conical and parallel twin screw barrels, modular screw barrel systems (with interchangeable liners and screw elements), and specialty variants including bimetallic (B-101/B-201/B-301 grades functionally equivalent to Xaloy 101/306/800), PTA-coated, rubber-processing, and injection-molding screw barrels, plus accessories such as RSP (rapid screw protection) components, feed bushings, mixer tips, and barrel heads.

The underlying technology centers on metallurgical engineering and surface treatment: bimetallic barrel manufacturing, HVOF (High Velocity Oxygen Fuel) thermal spray coating for dense, low-stress wear-resistant surfaces, PTA coating with Colmonoy 83 nickel-chromium-tungsten-boron alloy, and tungsten-content screw barrels (30-40% tungsten) claimed to deliver 2x operational life versus standard alternatives. Manufacturing capability spans 5mm to 500mm diameter and 100mm to 10000mm length, with complete drawings available for major machine brands including Engel, Toshiba, Haitian, Cincinnati Milacron, KraussMaffei, Davis Standard, Battenfeld, and Weber.

The business model is export-focused direct manufacturing sales with quote-based pricing, no recurring contracts, and no public pricing tiers. An International Trade Department handles direct B2B sales to enterprise OEMs and processors in USA, Germany, Italy, Canada, Brazil and other markets, supported by a multilingual website in nine languages and an agent/distributor network in developing countries offering 5-10% channel discounts and lead referrals. Revenue is generated through one-time hardware sales of screw barrels, replacement parts, and accessories to plastic machinery OEMs and aftermarket processors across 10+ countries.

Products and services

• Screw Barrels for Plastic and Rubber Processing Custom-manufactured screw and barrel assemblies used in plastic injection molding, extrusion, and rubber processing machinery; supplied to OEMs and end-user processors requiring components matched to specific machine dimensions and materials.
• Bimetallic Barrels Bimetallic barrels produced with a wear-resistant alloy liner over a tough steel substrate, designed for abrasive, glass-filled, or corrosive polymer processing where standard nitrided barrels wear prematurely.
• Tungsten Carbide Screws and Barrels Screw and barrel components incorporating tungsten carbide for use in highly abrasive polymer and compound processing applications where extended service life is required.
• HVOF / PTA Coated Barrels Barrels finished with HVOF thermal spray or PTA weld-deposited wear-resistant coatings, supplied to processors needing upgraded wear performance in existing equipment without full barrel replacement.
