The company states that it produces about 1,000 sets of moulds annually and exports most of its output to more than 30 countries and regions, placing it within the internationally oriented cluster of mould makers that support the global plastics piping industry.
The company positions itself around technical design capability, large-size mould construction, and process precision, using CAD, UG, and Pro-E software and modern machining equipment to produce customer-specific tools. Its reported portfolio also includes specialised solutions such as collapsible core systems and automatic unscrewing systems, which are important in complex injection moulding applications where threaded or difficult-to-demould pipe fittings must be produced efficiently.
History and Development
Yongmao’s published materials present the company as a long-established Huangyan mould producer focused on pipe fitting moulds and export markets. A directory listing identifies the firm as a manufacturer with a recorded registration entry in 2008, indicating an established commercial presence in the export mould sector by that period.
Several development milestones are visible in the company’s public profile:
- It built its business around plastic pipe fitting moulds rather than general-purpose moulding, concentrating on a technically demanding niche within the plastics industry.
- It expanded from standard fitting tools into large-size moulds and advanced mechanisms such as collapsible core and automatic unscrewing solutions.
- It internationalized its sales base, with export-oriented activity reaching 30+ countries and regions and a claimed export share of 90%+.
This trajectory reflects the broader evolution of the Huangyan mould cluster, where small and mid-sized manufacturers have moved toward specialized, export-driven tooling for global pipe systems, building products, and infrastructure applications.
Business Operations and Segments
Yongmao’s business is centered on the tooling segment of the plastics value chain, supplying the moulds used by injection moulders who manufacture plastic fittings. Its operations appear to combine:
- Product development and mould design
- Precision machining and mould manufacture
- Custom engineering for customer-specific fitting geometries
- Export sales and international customer support
The company describes itself as a specialist in moulds for several application categories, including:
- Wastewater systems
- Drinking water supply systems
- Water and gas distribution systems
- Chemical process industry fittings
- Building materials
- Exhaust systems
- Irrigation systems
This portfolio indicates that Yongmao serves infrastructure-linked end markets where long service life, dimensional consistency, and reliable demoulding are important performance requirements.
Products and Technologies
Yongmao’s product line focuses on plastic pipe fitting moulds for a range of thermoplastics and piping standards. The company’s published product categories include:
- PVC pipe fitting moulds
- PE pipe fitting moulds
- PP pipe fitting moulds
- PPR pipe fitting moulds
- PPSU pipe fitting moulds
- Special fitting moulds
Within these categories, the company lists or implies support for fitting types used in:
- Drainage and sewage systems
- Water supply systems
- Rainwater systems
- Irrigation systems
- Gas distribution
- Electrofusion, butt fusion, and compression fittings
From a technical standpoint, pipe fitting moulds differ from simpler injection tools because they must manage thread forms, undercuts, wall thickness control, cooling balance, and demoulding forces. Yongmao’s emphasis on collapsible core systems and automatic unscrewing systems suggests capability in mould designs used for fittings with internal threads or complex release geometries, where conventional straight-pull tooling is insufficient.
The company also states that it uses:
- CAD / UG / Pro-E design software
- Modern production equipment
- High-quality mould steel
- Advanced workshop management systems
Its claimed mould diameter range of 16 mm to 700 mm indicates coverage from smaller household and utility fittings to larger infrastructure components, which typically require more demanding structural rigidity and thermal management in the mould design.
Applications and End Markets
Yongmao’s moulds are used in the production of plastic fittings for infrastructure and building-services markets. The main end-use sectors identified in its materials include:
- Municipal and building drainage
- Potable water distribution
- Gas distribution
- Irrigation and agricultural water systems
- Roof drainage
- Chemical process piping
- Exhaust and ventilation systems
These applications align with broader plastics-industry trends in which pressure, corrosion resistance, installation efficiency, and lifecycle cost continue to support thermoplastic piping systems in many regions.
Global Presence and Market Position
Yongmao reports exports to more than 30 countries and regions, with overseas markets including Europe, Latin America, Asia, South Korea, Russia, South America, Turkey, and the Middle East across its published profiles. The company states that 90%+ of its output is exported, making international business central to its operating model.
The firm’s market position is best understood as that of a specialized export mould maker within China’s broader mould-manufacturing ecosystem. Rather than a diversified plastics processor, Yongmao serves as an upstream equipment and tooling supplier to pipe fitting manufacturers, where competitiveness depends on design accuracy, delivery reliability, and the ability to customize tools for specific standards and customer requirements.
Research and Development
Yongmao presents engineering and development capability as a core differentiator. Its reported R&D-related strengths include:
- Use of 2D and 3D design software
- Experience in custom mould engineering
- Ability to develop large-size and high-precision moulds
- Work on collapsible core and automatic unscrewing technologies
In the plastics tooling sector, these capabilities are significant because pipe fitting moulds often require careful coordination of mould steel selection, cooling design, gate location, cavity balance, and ejection strategy. Firms that can iterate such tooling quickly are better positioned to serve international customers seeking shorter development cycles and product variants tailored to local piping standards.
Quality Management and Certifications
The company states that it has obtained ISO 9001 quality management system certification and import-export operating rights. In export-oriented mould manufacturing, ISO 9001 is often used as evidence of formalized process control, documentation, and corrective action routines, although customer qualification typically also depends on tool performance, dimensional consistency, and long-term service support.
Sustainability and Environmental Context
Yongmao’s published materials do not frame sustainability as a primary corporate theme, but its product line is tied to infrastructure systems that can support long-service-life plastic piping in water, drainage, and irrigation applications. In the wider plastics industry, such applications are often evaluated through durability, corrosion resistance, and installation efficiency, alongside end-of-life and resource-use considerations.
The company’s focus on customized moulds for engineered piping components suggests participation in a segment where product performance and material efficiency can influence the environmental profile of downstream plastic systems. In this context, mould precision can affect scrap rates, dimensional rejection, and process stability in the customer’s injection moulding operations.
Innovations and Future Outlook
Yongmao’s future prospects are likely to be shaped by demand for infrastructure plastics, specialized pipe systems, and export-grade mould quality. Its technical focus on large fittings, specialty demoulding mechanisms, and customer-specific tooling positions it to benefit from continued replacement and expansion of plastic piping systems in construction, utilities, and agricultural water management.
The company’s competitive challenge is typical of the tooling sector: maintaining precision, shortening lead times, and continually upgrading design and machining capability while serving a globally distributed customer base. Its emphasis on engineering customization and export markets suggests a business model built on technical specialization rather than high-volume standardization.
