Introduction
Zhangjiagang Jiuwei Machinery Co., Ltd. (张家港玖威机械有限公司) is a Chinese plastics machinery and mold-making company based in Fenghuang Town, Zhangjiagang City, Jiangsu Province. The company focuses on blow molding and injection blow molding equipment as well as the associated molds and tooling, serving manufacturers that produce plastic bottles, caps, and related containers.
Within the plastics industry, Jiuwei occupies the segment of specialized processing machinery, where equipment design, mold engineering, and process stability are closely linked. Its product scope includes fully automatic three-station injection blow molding machines, blow molding machines, and supporting molds such as PET preform molds*, **hot runner bottle cap molds, and **injection-blow molds. The company’s presence at industry platforms such as **Chinaplas 2026* indicates its participation in the broader regional and international plastics equipment market.
History and development
Jiuwei Machinery was established in 2011 and is registered as a limited liability company engaged in general-purpose equipment manufacturing. Public business-record data also identify the company as operating in the mold manufacturing and broader machinery sector, with a registered capital of RMB 1 million.
Several development milestones are visible from its public-facing materials:
- The company built its business around plastic processing machinery and mold R&D, combining engineering staff with practical manufacturing experience.
- It expanded its offer beyond machines to include matched tooling and molds, especially for bottle-making and cap-making applications.
- Patent activity suggests continued technical development; a public report states that the company had 41 patents and had participated in two bidding projects.
Business operations
The company’s registered business scope includes the manufacture, processing, and sale of machinery and parts, as well as hardware molds and trading activities in plastics-related materials and products. It also lists import and export operations for goods and technologies.
Its operating model appears to combine:
- Machine manufacturing
- Mold and tooling support
- Engineering-oriented customization
- Domestic and overseas trade
Public supplier descriptions characterize the firm as serving both manufacturing and trading functions, which is common among Chinese machinery makers that sell into export-oriented packaging and container markets.
Products and technologies
Jiuwei’s core technical focus is injection blow molding and related tooling. Injection blow molding is widely used for producing hollow plastic containers with controlled neck finishes and good dimensional repeatability, making it suitable for packaging applications that require consistent bottle geometry.
Main product categories
- JWM series fully automatic three-station one-step injection blow molding machines
- Blow molding machines and bottle blow molding machines
- Injection blow molding machines in different model sizes, including publicly listed JWM models such as JWM300 and JWM450.
- Molds and tooling, including:
- Bottle molds
- Cap molds
- PET preform molds
- Hot runner bottle cap molds
- Extrusion blow molding molds
- Injection-blow molds
Technical emphasis
The company describes its work as centered on mold design and supporting services for both its own machinery and for other automatic three-station injection blow molding machine manufacturers. This indicates a capability profile that extends beyond machine assembly into process-compatible tooling, which is critical for:
- cycle stability,
- part consistency,
- neck finish accuracy,
- and production efficiency in bottle manufacturing.
Applications and end markets
Jiuwei’s equipment is primarily relevant to the plastic packaging sector, especially where molded containers are required. Based on the products publicly described, its technology is most directly associated with:
- Plastic bottles and containers
- Bottle closures and caps
- Preforms and hollow-article packaging components
- Packaging lines requiring injection blow molding
The company’s published materials do not provide a full sector-by-sector customer list, so broader end-use claims should be treated cautiously. However, the product mix clearly places it within the supply chain that serves beverage, household, personal care, and general packaging applications, where molded plastic containers are commonly used.
Global presence and market position
Jiuwei is headquartered in Zhangjiagang, a manufacturing center in Jiangsu Province with strong logistics access to the Yangtze River Delta industrial corridor. The company’s own descriptions highlight transport convenience and proximity to major economic nodes, which supports domestic distribution and export activity.
Its market position appears to be that of a specialized mid-sized machinery supplier rather than a large diversified industrial group. Public records indicate a workforce in the 50–99 employee range, with about 50 insured employees in 2025. This scale is consistent with a focused equipment maker serving niche packaging and mold applications.
Its listing on Chinaplas Online and other supplier platforms suggests visibility in the plastics trade-show and B2B sourcing ecosystem.
Sustainability and environmental considerations
Public sources reviewed for Jiuwei do not describe a formal, detailed sustainability program, renewable-energy strategy, or emissions-reporting framework. For a machinery maker in the plastics sector, the main environmental relevance lies in the performance of the equipment it supplies: more stable molding processes, better material utilization, and lower scrap rates can indirectly reduce waste in downstream production.
At the same time, as with other plastics-processing equipment companies, the firm operates within an industry facing increasing pressure to improve:
- energy efficiency
- material efficiency
- recyclability of packaging formats
- process consistency and waste reduction
Because Jiuwei has not publicly disclosed comprehensive sustainability metrics in the sources reviewed, any stronger environmental assessment would be speculative.
Financial performance and economic footprint
The company is privately held, and no audited financial statements were identified in the available sources. Public registry data show a registered capital of RMB 1 million. Beyond that, financial performance cannot be verified from the materials reviewed.
Its economic footprint is clearer in operational terms: the company contributes to the regional machinery cluster in Zhangjiagang and participates in the manufacturing of equipment used by plastics processors. Patent activity and export-trade registration also indicate that the business is not limited to a purely local market.
Leadership and corporate information
Public business records identify Jiang Xiaofeng as the company’s legal representative. The company is registered in Zhangjiagang City, Suzhou, Jiangsu Province, with its operating address given as Port Development Zone, Fenghuang Town.
Available sources do not provide a full board structure or governance framework. As a privately held machinery company, its public governance disclosure appears limited to statutory registration data and contact information.
Innovations and future outlook
Jiuwei’s patent count and focus on mold engineering suggest an ongoing emphasis on incremental technical innovation rather than large-platform industrial diversification. In plastics machinery, future competitiveness often depends on several factors:
- machine reliability and uptime
- tooling precision
- compatibility with downstream packaging requirements
- automation and process repeatability
- ability to support customization for specific bottle and cap formats
The company’s continued relevance will likely depend on how effectively it adapts its injection blow molding and mold portfolio to changes in packaging design, material efficiency expectations, and customer demand for production stability. Its participation in industry exhibition channels indicates an interest in maintaining market visibility and accessing new customers.
Summary
Zhangjiagang Jiuwei Machinery Co., Ltd. is a specialized Chinese plastics machinery manufacturer focused on injection blow molding equipment and related molds. Established in 2011 and based in Zhangjiagang, Jiangsu, it operates at the intersection of machine building, tooling, and packaging-process support, with publicly visible activity in patents, export registration, and plastics industry exhibition networks.
