Introduction
Zhoushan Chuangri Screws Machinery Co., Ltd. (舟山市创日螺杆机械有限公司) is a Chinese manufacturer specializing in screws, screw barrels, and related components for plastic extruders and injection molding machines. The company is based in Zhoushan, Zhejiang Province, within the Jintang area of the city’s well-known plastics machinery cluster, a region widely associated with screw-barrel manufacturing for the global plastics industry.
Founded in 1990 according to the company’s public profile, Chuangri has developed into a specialized producer offering OEM and ODM services, with reported experience across more than 500 customer companies and more than 4,600 projects worldwide. Its product and process emphasis is on wear resistance, corrosion resistance, and service life, which are critical performance factors for screws and barrels used in extrusion and injection molding applications.
The company’s public materials also describe an advanced manufacturing base that includes CNC machining, threading, turning, milling, grinding, polishing, nitriding, quenching, bimetallic coating, and alloy coating processes, supported by an in-house design team and inspection procedures. In the context of the plastics industry, this places Chuangri in the segment of precision equipment and wear-part manufacturing that supports polymer processing, machinery maintenance, and replacement markets.
History and Development
Chuangri’s published company profile states that it was established in 1990, making it one of the earlier Zhoushan-based enterprises focused on screw-barrel research and development. Another business record lists the company’s formal registration date as 2001-07-03, which may reflect incorporation or later registration rather than the original founding year.
Over time, the company has emphasized three development themes:
- From manufacturing to integrated service: public materials describe a business model combining product design, production, sales, and after-sales service.
- From standard parts to customized solutions: the company reports OEM and ODM capability, as well as custom design, modification, mapping, and repair services for worn screws.
- From domestic production to export-oriented supply: customs-related records indicate cross-border trade activity, with reported shipments to markets including India, Nigeria, and Malaysia.
These milestones reflect a typical development path for specialized Zhoushan screw-barrel manufacturers: local industrial roots, gradual investment in process capability, and expansion into aftermarket and export channels.
Business Operations and Segments
Chuangri operates as a manufacturer of plastic machinery parts, with its business scope described in public registration data as the production and sale of plastic machinery and accessories, plus import and export trade.
Its core operational segments can be summarized as follows:
- Screw and barrel manufacturing
- Component production for extrusion and injection molding machines
- OEM/ODM contract manufacturing
- Repair and refurbishment of worn screws
- Export and foreign trade services
This business profile positions the company within the downstream supply chain of plastics processing machinery, serving equipment builders, processors, and maintenance markets rather than producing polymers themselves.
Products and Technologies
Chuangri’s public descriptions identify its main product family as screws and related parts for plastic extruders and injection molding machines. In practice, this product category typically includes items such as:
- Single screws
- Twin screws
- Screw barrels
- Wear-resistant replacement components
- Customized or rebuilt screws for existing equipment
The company states that it uses advanced CNC machining equipment and multiple finishing and treatment processes, including:
These processes are significant because screw-barrel performance depends on precise geometry, surface hardness, and resistance to abrasion, corrosion, and thermal stress. Chuangri’s published claims emphasize these performance attributes as the basis for longer service life and suitability as replacements for imported parts.
The company also reports a professional screw design team and a rigorous inspection process, indicating that engineering support and quality control are central to its value proposition.
Applications and End Markets
Chuangri’s products are used in machinery that processes plastics and related materials, with applications tied to:
- Plastic extrusion
- Injection molding
- Replacement and refurbishment of worn machine parts
- OEM machine builds and aftermarket servicing
The wider Zhoushan screw-barrel industry commonly supplies processors in packaging, piping, profiles, sheet, and molded-part production; Chuangri’s technical positioning suggests it serves similar industrial users, although its public materials do not provide a fully itemized end-market breakdown.
Global Presence and Market Position
The company is headquartered in Zhoushan, Zhejiang, a location internationally associated with plastic machinery component manufacturing. Chinaplas exhibitor materials classify the company as a plastics and rubber supplier, confirming its visibility within the industry exhibition ecosystem.
Public customs-related data indicate export activity to several countries, with India appearing as the most frequently recorded destination among the limited data shown. This suggests that Chuangri participates in the international replacement-parts and machinery-components market, though the available data are insufficient to quantify its full global scale.
In market terms, Chuangri appears to be a specialized mid-sized industrial supplier rather than a diversified multinational. Its competitive positioning is based on technical manufacturing capability, customization, and application-specific wear performance.
Sustainability and Environmental Initiatives
No detailed sustainability report was identified in the available sources. However, the company’s emphasis on repair, refurbishment, and replacement of worn screws may contribute indirectly to resource efficiency by extending the life of industrial equipment and reducing premature part replacement.
The company’s public materials do not provide enough information to assess energy management, emissions controls, recycling programs, or formal environmental certification beyond a reference to ISO 9001:2008 quality management compliance in older profile material.
Financial Performance and Economic Impact
Chuangri is a privately held manufacturing company, and no audited financial statements were identified in the available sources. Public registration data indicate a registered capital of 1 million RMB and a workforce of fewer than 50 employees, suggesting a relatively small enterprise structure.
Its economic impact is better understood through industrial role than through disclosed financial metrics:
- supporting regional machinery manufacturing in Zhoushan
- supplying critical wear parts for plastics processors
- participating in export trade
- contributing to the aftermarket for imported and domestic equipment
Leadership and Corporate Governance
Public business records list Zhang Yongcai as the legal representative. The company is registered as a limited liability company with natural person investment or control, indicating a private ownership structure.
Available sources do not provide detailed board composition, senior management biographies, or formal governance disclosures. The most visible management-related signals are its quality-system emphasis, inspection procedures, and design-led operating model.
Innovations and Future Outlook
Chuangri’s innovation profile is centered on materials engineering, machining precision, and wear-resistant surface treatments rather than on polymer formulation or machinery assembly. In this sector, competitive differentiation often depends on the ability to tailor screw design to abrasive, corrosive, or high-fill processing conditions.
Likely future priorities for a company of this type include:
- expanding customized design and refurbishment services
- improving alloy and coating performance
- serving more demanding polymer-processing applications
- strengthening export sales through trade fairs and distributor channels
Its long-term prospects will depend on demand for replacement parts, modernization of extrusion and injection equipment, and the continuing need for higher-performance screws in recycled-content, filled-compound, and corrosive-processing applications.
