Introduction
Zhoushan Jintang Afei Plastic Machinery Factory (舟山市金塘阿飞塑料机械厂) is a Chinese manufacturer of plastic machinery components, specializing primarily in screws, barrels, and related parts for injection molding machines, extruders, rubber machinery, and chemical-fiber equipment. The company is based in Xihou Industrial Zone, Jintang Town, Dinghai District, Zhoushan, Zhejiang Province, an area widely associated with China’s screw-and-barrel manufacturing cluster.
Its product range includes single-screw and twin-screw assemblies, injection-molding screws and barrels, conical and parallel twin screws, rubber-machine screws, chemical-fiber machine components, bimetallic and tungsten-base alloy screws and barrels, and gearboxes, indicating a business focused on wear-resistant, high-precision processing parts used throughout polymer conversion equipment. The company presents itself as a specialist in customized machining and repair services, including mapping, redesign, and remanufacturing for worn screws and barrels, which places it within the industrial ecosystem supporting machine builders and downstream plastics processors.
History and Development
Publicly available source material provides limited formal corporate-history detail, but the company’s own descriptions indicate a business built around the long-established Zhoushan screw industry and its local machining capabilities. The firm states that it manufactures parts from 38CrMoAlA alloy steel using processes such as quenching and tempering, nitriding, precision grinding, and polishing, suggesting an emphasis on durability and dimensional accuracy from its development stage onward.
Two practical milestones are visible in its published materials:
- The company expanded from standard screw-and-barrel production into specialized alloy and bimetallic wear-resistant products, reflecting adaptation to higher-performance requirements in plastics and rubber processing.
- It added repair and customization services, including sample-based processing and remanufacturing of worn components, which broadened its role from parts supplier to technical service provider.
- Its continued presence in exhibition and supplier directories shows participation in the broader industrial trade network centered on plastics machinery and extrusion-related components.
Business Operations and Segments
The company’s operations are concentrated in the manufacture of core consumable and replacement parts for polymer-processing equipment. These components are critical to the melting, mixing, conveying, and metering functions of extrusion and injection systems, making them high-value wear parts in plastics manufacturing.
Main business areas include:
- Injection molding components
- Extrusion screws and barrels
- Rubber-processing screws and barrels
- Twin-screw systems
- Chemical-fiber and blow-molding related screws
- Component repair, modification, and sample-based custom fabrication
This portfolio aligns the factory with machine builders, maintenance contractors, and processors that require replacement parts with tight tolerances and wear resistance rather than complete processing lines.
Products and Technologies
The company’s published product list covers a broad set of screw-and-barrel formats used across plastics and rubber processing. Notable product categories include:
- Injection-molding screws and barrels
- Single-screw extrusion screws and barrels
- Parallel twin screws
- Conical twin screws
- Planetary screws
- Granulation-machine screws
- Blow-film machine screws
- HDPE and PPR high-speed screws
- PVC-specific screws
- Bimetallic and tungsten-based alloy screws and barrels
- Stainless-steel screw and barrel variants
The technical emphasis is on wear resistance, corrosion resistance, and service life. According to the company, standard products are made from 38CrMoAlA steel and receive nitriding or alloy spraying, followed by fine grinding and polishing, a conventional but technically demanding route for improving surface hardness and dimensional stability in processing screws. The company also states that it can use double-alloy powder repair technology to restore worn screws and barrels, which is important for cost control in processor maintenance cycles.
In industry terms, these products serve the functional heart of polymer conversion equipment. Screw geometry, surface treatment, and barrel material selection affect plasticizing efficiency, melt homogeneity, output stability, and wear life, especially when processing abrasive or corrosive compounds such as filled PVC, engineering plastics, and rubber mixtures. That technical context makes the company’s specialization relevant to machine uptime and process consistency.
Applications and End Markets
The factory’s products are described as suitable for a range of domestic and imported machines used in:
- Injection molding
- Extrusion
- Rubber processing
- Chemical-fiber spinning and drawing
- Blown-film production
- Granulation and compounding
This customer base indicates exposure to multiple segments of the plastics value chain, from resin conversion to engineered rubber and fiber applications. Because screws and barrels are replacement-heavy components, the company’s end markets are driven not only by new-equipment demand but also by maintenance, refurbishment, and retrofit activity.
Global Presence and Market Position
Available sources show the company’s presence mainly through its own website and industry directory listings rather than through a detailed public filing record. The firm is located in Zhoushan, a city strongly associated with screw and barrel manufacturing, which gives it geographic proximity to a dense industrial supplier base and to the logistics corridors serving eastern China’s plastics machinery sector.
Its market position appears to be that of a specialized regional manufacturer serving both domestic and foreign machine users through standard and custom parts. The company’s emphasis on replaceable wear components, repair services, and alloyed products suggests competition in a technically segmented market where reputation, machining quality, delivery reliability, and material performance are more important than scale alone.
Sustainability and Environmental Initiatives
No detailed public sustainability report was identified in the available sources. However, the company’s repair and remanufacturing offerings have an indirect sustainability dimension because restoring worn screws and barrels can reduce material consumption and extend equipment life.
Its focus on longer-life wear-resistant alloys may also reduce replacement frequency in service-intensive applications, although the environmental effect depends on operating conditions, processing intensity, and the downstream recycling or disposal practices of customers. No independent data were found on emissions, energy intensity, or formal environmental certifications.
Financial Performance and Economic Impact
The company has not published financial statements in the available sources, and no reliable revenue or profitability data were identified. As a result, its financial performance cannot be verified from the provided material.
Economically, the factory contributes to the plastics machinery supply chain by manufacturing critical consumables and replacement parts. In Zhoushan’s industrial cluster, such firms support machine builders, converters, maintenance providers, and exporters that depend on precision metalworking and stable component supply.
Leadership and Corporate Governance
No detailed governance disclosures, board information, or executive profiles were identified in the available sources. The company appears to operate as a factory-level private manufacturer, with public-facing contact information centered on its business address, telephone, and website.
Innovations and Future Outlook
The company’s technical direction appears to center on materials engineering, surface hardening, and custom refurbishment rather than on full machinery systems. That positioning is consistent with broader plastics-industry trends in which processors seek:
- longer service intervals,
- better wear and corrosion resistance,
- lower maintenance costs,
- and rapid turnaround for replacement parts.
Future competitiveness for firms in this segment typically depends on their ability to improve alloy performance, maintain tight dimensional tolerances, and provide responsive customization for evolving resin formulations and high-throughput processing lines. The company’s stated openness to technical exchange with domestic and international peers suggests an interest in incremental process and product development.
