Introduction
KINGSUN PRECISION MOULD (DONGGUAN) CO., LTD. is a Dongguan-based Chinese manufacturer of plastic injection moulds and die-casting moulds, with related capabilities in tool building and the production of moulded parts. The company operates within the precision tooling segment of the plastics industry, where high-accuracy mould design and fabrication are essential to mass production in sectors such as consumer goods, industrial components, and other engineered applications.
Publicly available records indicate that the business has been active since at least 2005, when it was described as a precision mould maker and parts supplier in Dongguan. The company has also been associated with a broader precision-manufacturing profile that includes mould building, injection and die-casting parts supply, machining, and surface treatment, suggesting a vertically integrated service offering rather than a single-process workshop model.
The firm appears to have expanded its technical base over time, including the introduction of high-end equipment such as Makino CNC machine tools, mirror EDM systems, sinker EDM machines, Hexagon coordinate measuring machines, and Okamoto grinding machines. Such equipment is characteristic of precision mould manufacturing, where tool accuracy, surface finish, repeatability, and dimensional control directly affect part quality and production stability.
History and Development
Available records support several milestones in the company’s development:
- 2005: Company activity is documented from this period, with the business described as a precision mould maker and parts supplier in Dongguan.
- 2012: A related company reference indicates that Baishuo & KingSun Precision Mould Co., Ltd. was founded in 2012, suggesting corporate development or restructuring within the KingSun business family.
- 2024: The company was included among Guangdong’s high-tech enterprise recognition records, indicating formal acknowledgment of its technology-oriented manufacturing profile.
- 2024: It also appeared in Guangdong’s list of technology-oriented small and medium-sized enterprises, reinforcing its classification as an innovation-driven industrial firm.
These milestones point to a business that has moved from conventional mould-making activity toward a more formally recognized precision manufacturing role within the regional industrial ecosystem.
Business Operations and Capabilities
KINGSUN PRECISION MOULD’s core business is centered on tooling for plastics and die casting, with supporting downstream part-production services. This business model places the company between product design and large-scale manufacturing, where mould performance strongly influences cycle time, yield, and part consistency.
Its reported operating scope includes:
- Plastic injection moulds
- Die-casting moulds
- Tool building
- Injection and die-casting parts supply
- Machining
- Surface treatment
The combination of tooling and parts production is commercially important because it allows a mould maker to participate in both the upfront engineering phase and the ongoing manufacturing phase. In the plastics industry, that can reduce handoff risk, shorten development timelines, and improve process optimization for customers.
Products and Technologies
The company’s technology profile is consistent with a precision mould shop serving demanding industrial customers. Reported equipment and process capabilities include:
- Makino V33i CNC machine tools for high-precision cutting and cavity/core machining
- Mirror EDM systems for fine-detail electro-discharge machining
- Sinker EDM equipment for shaping complex internal geometries
- Hexagon CMM inspection for dimensional verification and quality control
- Okamoto grinding machines for high-flatness and tight-tolerance finishing
In practical terms, these capabilities support the manufacture of moulds with:
- Complex geometries
- Tight dimensional tolerances
- High surface finish requirements
- Repeatable cavity performance
A separate company profile also describes experience in high-precision CNC machining, turn-milling, and sheet metal stamping, although that source presents a broader precision-manufacturing description that should be read as complementary rather than definitive for every legal entity using the KingSun name.
Applications and End Markets
The available sources do not provide a complete end-market breakdown for KINGSUN PRECISION MOULD itself, but its reported product and process mix indicates relevance to several plastics-adjacent manufacturing sectors.
Likely application areas include:
- Consumer and industrial plastic components
- Die-cast metal components and housings
- Precision-engineered parts requiring secondary machining
- Products requiring integrated moulding and finishing services
A company profile associated with the KingSun name states that its parts are used in medical devices, sport equipment, motorcycles, automobiles, aerial photography, model aircraft, and communications. That source is not specific to the Dongguan legal entity in every detail, but it is consistent with the kind of precision parts market served by advanced mould makers.
Global Presence and Market Position
KINGSUN PRECISION MOULD is rooted in Dongguan, Guangdong, one of China’s most concentrated manufacturing clusters for moulds, plastics processing, and precision tooling. Dongguan’s industrial base provides access to suppliers, machinists, surface-treatment vendors, logistics services, and downstream plastics processors, all of which are important for rapid tooling development.
The company also appears in exhibitor-related records connected with Chinaplas, including a listing for HongKong KingSun Mould Technology Co., Limited and a 2026 exhibitor entry for 东莞市鼎三精密模具有限公司 at booth 5.2G16. This suggests participation in the regional and international plastics trade-show ecosystem, where mould makers present tooling capabilities to processors, brand owners, and OEMs.
The company’s precise market share is not publicly disclosed in the available sources. Its position is best understood as that of a specialized precision mould manufacturer rather than a mass-market plastics processor or commodity resin producer.
Sustainability and Regulatory Recognition
No source reviewed here provides detailed environmental performance data, emissions figures, or certified sustainability targets for the company. However, the firm’s inclusion in Guangdong’s lists of high-tech enterprises and technology-oriented SMEs indicates formal policy recognition within China’s innovation framework.
In the plastics industry, precision mould makers can contribute indirectly to sustainability by improving:
- Part quality and consistency
- Material yield
- Cycle-time efficiency
- Scrap reduction
- Tool life
Those effects are inferred from the role of precision tooling and are not stated as company-specific sustainability claims in the available materials.
Financial Performance and Economic Impact
No audited financial statements, revenue figures, or employment totals were identified in the available sources. The most concrete economic indicators are the company’s continued operational presence in Dongguan and its official recognition in provincial technology and enterprise programs.
As a mould maker, the company contributes to the plastics industry’s upstream value chain by enabling the production of plastic parts that would otherwise be difficult or uneconomic to manufacture at scale. Precision toolmakers such as KINGSUN PRECISION MOULD are economically important because they support:
- Local manufacturing ecosystems
- Prototype-to-production transitions
- Export-oriented industrial supply chains
- Customer-specific product development
Leadership and Corporate Governance
Publicly available source material identifies Duan Yanshu as General Manager of KingSun Precision Mould (Dongguan) Co., Ltd. for the period from March 2005 to December 2021, and as General Manager of KingSun Precision Mould from January 2022 onward. Beyond this, no detailed governance structure, board composition, or ownership disclosure was identified in the reviewed sources.
Innovations and Future Outlook
The company’s equipment profile suggests a strategy built around precision, process control, and manufacturing capability depth rather than low-cost commodity tooling. In the plastics mould sector, that positioning is often associated with:
- More complex mould geometries
