Introduction
Zhangjiagang Tianjiang Precision Mould Co., Ltd. (张家港市天江精密模具制造有限公司), also known as TJ MOULD, is a Chinese manufacturer specializing in plastic injection moulds and plastic blow moulds for packaging and related applications. Founded in 1999 and based in Zhangjiagang City, Jiangsu Province, the company positions itself as a producer of high-end, customized moulding solutions for container, cap, bottle, and industrial packaging markets.
TJ MOULD describes its core business as the design and manufacture of personalized moulds for plastic container development, with product lines that include moulds for pharmaceutical packaging, food packaging, commodity packaging, chemical packaging, and other container formats. Company materials indicate that its manufacturing base has expanded over time to a modern plant of approximately 3,800 m² to 12,000 m² depending on the source and business profile cited, reflecting the company’s growth from a small workshop into a dedicated mould manufacturer with a technical workforce and export-oriented operations.
The firm’s public profile emphasizes technical precision, customization, and export capability, and it reports shipments to dozens of countries and regions across North America, Europe, the Middle East, Latin America, Africa, and Asia. In addition to mould fabrication, the company presents itself as a solutions provider covering mould design, machining, assembly, trials, and customer-specific development for packaging producers.
History and Development
TJ MOULD was established in 1999 in Zhangjiagang, a manufacturing center in eastern China with strong logistics links to the Yangtze River Delta industrial corridor. Early company descriptions present its development as a gradual scale-up from small production capacity to a dedicated precision mould operation serving both domestic and overseas customers.
Several milestones appear consistently in public records and company materials:
- 1999: Company founded and begins focusing on plastic mould design and manufacturing.
- 2008: The company reports certification to ISO 9001:2008, indicating the formalization of its quality management system.
- 2010s–2020s: The firm is referenced in multiple industry and government-related listings as a high-tech enterprise, a contract-abiding and creditworthy enterprise, and a specialized and innovative small and medium-sized enterprise in Jiangsu Province.
The company’s technical development also appears tied to specific project work and patent activity. Public patent and project records reference moulding technologies for products such as deep-thread bottle caps and a stacked hot-runner mould for large-volume infusion packaging, suggesting sustained specialization in packaging mould engineering.
Business Operations and Segments
TJ MOULD is primarily a custom mould manufacturer rather than a raw polymer producer or a plastics processor. Its operations center on the following business functions:
- Mould design and development
- Precision machining
- Assembly and testing
- Trial moulding and verification
- Export-oriented sales and customer support
The company’s reported workforce size varies by source, with public materials indicating approximately 80 employees in one company statement and 150 staff in other business-directory profiles. The variation likely reflects differences in reporting dates and data sources. Across sources, the common picture is of a medium-sized specialized manufacturer with engineering and production capabilities concentrated in a single site in Zhangjiagang.
Products and Technologies
TJ MOULD’s principal products are plastic injection moulds and plastic blow moulds. The company’s product portfolio is oriented toward packaging and closure systems, especially for containers used in consumer, food, medical, and industrial applications.
Main product categories
- Injection moulds for packaging containers and caps
- Blow moulds for bottles, drums, jerrycans, and related containers
- Cap and closure moulds, including threaded and flip-top formats

Technical capabilities
Publicly available supplier descriptions indicate that the company uses CNC machining, wire-cutting, precision grinding, and milling equipment, alongside a mould trial area equipped with an injection machine for validation. One profile also mentions advanced machining centers from Taiwan KAFO and Japan MAZAK, suggesting an emphasis on precision tooling infrastructure.
In industry terms, this places TJ MOULD in the specialized segment of mould manufacturing where dimensional accuracy, cooling design, hot-runner integration, parting-line control, and repeatability are central to product performance. The patent and project references to cap threads and stacked hot-runner systems further indicate that the company works on moulds with relatively demanding geometry and cycle-efficiency requirements.
Applications and End Markets
TJ MOULD serves packaging-related end markets rather than downstream plastic consumer goods directly. Its moulds are used in the production of:
- Pharmaceutical packaging
- Food packaging
- Commodity packaging
- Chemical packaging
- Industrial containers and drums
- Automotive-related packaging components
The company’s focus on cap, bottle, and closure moulds aligns it with sectors where mould performance affects sealing reliability, cycle time, and container uniformity. This is particularly relevant in pharmaceutical and food packaging, where dimensional consistency and functional integrity are critical.
Global Presence and Market Position
TJ MOULD presents itself as an export-oriented manufacturer with moulds reportedly sold to 50 countries and regions. Other business-directory and social profile sources list markets in North America, Western Europe, the Middle East, South America, Africa, and Asia, including the United States, Canada, Mexico, Brazil, the United Kingdom, France, Germany, Saudi Arabia, the United Arab Emirates, Russia, India, Thailand, and Indonesia.
The company’s presence on international trade and exhibition platforms, including Chinaplas’ eMarketplace and other exhibitor directories, indicates participation in the global plastics machinery and moulding supply chain. That visibility is consistent with a business model centered on international custom orders and packaging-industry networking rather than mass-market branded products.
Publicly available supplier databases describe the company as a verified manufacturer offering customization, although they do not provide independently audited market share data. No reliable public source in the available record establishes a precise global ranking, and any such claim would be speculative.
Sustainability and Environmental Initiatives
Publicly available information on TJ MOULD’s environmental strategy is limited. The company’s materials emphasize quality management, precision manufacturing, and product durability, but they do not provide detailed disclosures on emissions, energy use, recycling, or lifecycle design.
In the broader mould-making sector, sustainability improvements generally come from lower scrap rates, better process repeatability, lighter packaging designs, and moulds that support material-efficient container production. TJ MOULD’s focus on precision moulds for packaging applications may support such efficiency gains indirectly, but the available sources do not quantify environmental performance or formal sustainability targets.
Financial Performance and Economic Impact
The company is privately held, and no audited public financial statements were identified in the available sources. As a result, revenue, profit, and capital expenditure cannot be stated reliably.
Its economic footprint is better understood through operational indicators: a specialized manufacturing site, export sales, a technical workforce, and annual production volumes reported in public profiles. One source states an annual output of about 400 sets of moulds, while another mentions a similar scale of annual mould production. These figures suggest a business focused on higher-value custom tooling rather than high-volume commodity production.
Leadership and Corporate Governance
Public sources identify TJ MOULD as a private share-holding enterprise. However, detailed governance information, board composition, or ownership structure is not publicly documented in the sources reviewed.
The company’s public identity is built around quality systems and technical competence. It has been associated with ISO 9001 certification and with multiple local and provincial recognitions related to quality, credit, and technology classification. These designations are relevant in China’s industrial policy environment, where “specialized, refined, distinctive, and innovative” enterprises receive recognition for technical focus and manufacturing capability.
Innovations and Future Outlook
TJ MOULD’s innovation profile appears centered on packaging mould engineering, especially in closure systems and precision container tooling. References to patent activity and specialized project approvals suggest that the company has invested in technical refinement rather than broad product diversification.
Key future opportunities and challenges for the company are likely to mirror those of the wider plastics mould industry:
- rising demand for lighter and more material-efficient packaging
- increased need for high-cavitation, high-precision tooling
- pressure to improve energy efficiency and production consistency
- greater customer demand for customization and shorter development cycles
- ongoing competition from other regional mould suppliers in China and overseas
Its established export orientation and focus on packaging-related moulds may support continued participation in global supply chains, especially if it continues to invest in machining precision, engineering design, and project-based innovation.
