Introduction
ZHOUSHAN NISSEI PLASTIC MACHINERY CO., LTD. (舟山市中日精塑料机械有限公司) is a Chinese plastics machinery supplier based in Zhoushan, Zhejiang Province, and is identified in industry directories as a manufacturer of screws, barrels, and related injection-molding-machine components. The company appears to operate within the broader Nissei business ecosystem associated with Japan’s NISSEI PLASTIC INDUSTRIAL CO., LTD., a long-established injection molding machine maker founded in 1947 with a global manufacturing and sales network.
Within the plastics-processing industry, the company is positioned in the downstream machinery and precision-parts segment, supporting injection molding and extrusion equipment through wear-resistant and precision-engineered consumables such as screws and barrels. Zhoushan’s wider industrial context is relevant here: the city is widely associated with plastics-machinery component manufacturing, especially precision screw and barrel production, which makes the company’s location strategically aligned with its product focus.
History and Development
The available public record on the Zhoushan company is limited, but several verified milestones help place it in context.
- The company was operating as a recognized supplier by the time it appeared in industry and business directories, where it is described as a manufacturer of screws and barrels for injection molding machines and extruders.
- It was listed among Zhoushan’s fourth batch of innovative small and medium-sized enterprises in Zhejiang Province in 2024, indicating official recognition within the local innovation system.
- Its presence in trade and exhibition listings suggests participation in the regional plastics-processing supply chain and in industry-facing commercial channels.
The company should also be understood against the background of the broader NISSEI group’s China expansion. NISSEI opened its Haiyan factory in January 2024 for injection molding machine assembly and parts machining, reflecting a strategy of localizing production and strengthening regional supply chains. NISSEI also maintains manufacturing operations in Taicang, China, further indicating a substantial industrial footprint in the country.
Business Operations and Segments
ZHOUSHAN NISSEI PLASTIC MACHINERY CO., LTD. appears to focus on a specialized component-manufacturing role rather than complete machine assembly. Its product emphasis is consistent with the needs of plastics processors that require durable, high-precision melt-handling parts for stable production.
Its business profile is most clearly associated with:
- Injection molding machine components
- Extruder components
- Precision wear parts, especially screws and barrels
This specialization places the company in the industrial supply chain that supports:
- machine builders,
- plastics processors,
- maintenance and refurbishment operations,
- and replacement-part markets.
Products and Technologies
Public listings and trade references indicate that the company’s core products include screws and barrels. In plastics processing, these are critical precision components that directly affect plasticizing performance, melt homogeneity, output stability, and wear resistance. Because these parts operate under high temperature, pressure, and abrasion, product quality depends on material selection, surface treatment, dimensional accuracy, and consistency in machining.
Typical technical requirements in this segment include:
- Dimensional precision for proper fit and stable processing
- Wear resistance for processing abrasive resins and filled compounds
- Corrosion resistance for materials that are chemically aggressive or moisture-sensitive
- Thermal durability for sustained operation under injection and extrusion conditions
The company’s product mix aligns with the general technical demands of injection molding and extrusion equipment, where screws and barrels are central to plasticizing, conveying, mixing, and metering polymer melts.
Applications and End Markets
The company’s products are used in markets that rely on continuous plastics processing, particularly:
- Injection molding
- Extrusion
- General plastics conversion
- Maintenance and replacement-part supply
These end markets typically include:
- packaging,
- automotive parts,
- consumer goods,
- appliances,
- industrial components,
- and other manufactured goods requiring thermoplastic processing.
Because screws and barrels are consumable or service-replacement items in many production environments, the company likely serves both original-equipment and aftermarket demand, although the exact balance is not publicly disclosed.
Global Presence and Market Position
The Zhoushan company’s public footprint is primarily China-based, but its branding and exhibition presence suggest alignment with a larger cross-border plastics-machinery ecosystem. The company is connected in naming and industrial identity to NISSEI, whose corporate network spans multiple regions and includes production bases in Japan, China, Thailand, and the United States.
NISSEI PLASTIC INDUSTRIAL’s corporate materials describe a global footprint with operations in over 80 countries and a network of domestic and overseas locations, indicating that the Zhoushan entity sits within a broader international industrial supply chain, even if its own direct export reach is not publicly detailed.
In market-position terms, the Zhoushan company appears to occupy a specialized niche rather than a mass-market role. Its significance lies in precision component supply for plastics machinery, a segment where reliability and fit are more important than brand visibility alone.
Sustainability and Environmental Initiatives
No detailed sustainability report specific to ZHOUSHAN NISSEI PLASTIC MACHINERY CO., LTD. was identified in the available sources. However, the broader industry context matters: plastics machinery makers increasingly focus on energy efficiency, material savings, process stability, and longer component life, all of which can reduce waste and operating costs.
At the group level, NISSEI emphasizes localized production and efficiency improvements in China and the United States, including bringing parts machining in-house and producing machines closer to demand centers. For a component manufacturer such as the Zhoushan company, sustainability relevance likely lies in:
- extending component service life,
- improving wear performance,
- reducing downtime and scrap,
- and supporting more stable, resource-efficient molding or extrusion operations.
Financial Performance and Economic Impact
No standalone financial statements for ZHOUSHAN NISSEI PLASTIC MACHINERY CO., LTD. were identified in the available materials. The company appears to be privately held and not separately disclosed in the sources consulted.
Its economic impact is best understood at the regional level. Precision screw-and-barrel production contributes to:
- industrial employment,
- local manufacturing capability,
- equipment servicing ecosystems,
- and the supply security of plastics-processing machinery in Zhejiang and the wider Yangtze River Delta.
The company’s recognition as an innovative small and medium-sized enterprise in Zhejiang suggests local policy relevance and industrial value beyond its immediate sales footprint.
Leadership and Corporate Governance
The available public sources do not provide a complete governance profile for ZHOUSHAN NISSEI PLASTIC MACHINERY CO., LTD. The company appears in directories and contact listings, but not in a way that reveals detailed board structure or audited governance reporting.
By contrast, the associated NISSEI group publishes formal corporate information, including its president, board members, capital base, and listed-company status in Japan. That contrast underscores the difference between a public parent-level manufacturer and a more specialized local operating company.
Innovations and Future Outlook
The company’s innovative potential lies in a technically demanding niche where performance improvements can matter greatly. In screw and barrel manufacturing, future competitiveness typically depends on:
- materials engineering
- surface hardening and wear protection
- tight machining tolerances
- application-specific design for filled, recycled, or heat-sensitive polymers
- compatibility with more automated and energy-efficient processing lines
Its inclusion in Zhejiang’s innovative SME recognition list suggests that local authorities consider it part of the region’s upgrading industrial base. In addition, the broader NISSEI group’s investments in Chinese and U.S. production localization point to continuing demand for regionalized supply, faster delivery, and cost-efficient machine and component support.
Summary
