Introduction
TAIZHOU HUANGYAN DAELONG MOLD CO., LTD. is a Chinese manufacturer of plastic molds and cap compression molding equipment based in Huangyan, Taizhou, Zhejiang, a major industrial cluster for mold making and plastic processing. The company focuses on PET preform molds, bottle cap molds, high-speed cap compression molding machines, and related tooling for packaging applications, especially in the beverage, drinking water, cosmetic, and broader plastic packaging sectors.
The company presents itself as a technology-oriented enterprise established in July 1993, with product development centered on mold design, precision tooling, and integrated cap-forming systems. Public business listings also identify it as a manufacturer and trading company founded in 2006, which likely reflects a later formal registration or reorganization of the same operating business under its current legal entity name. In industry terms, Daelong occupies the niche between mold fabrication and specialized packaging machinery, supplying equipment and molds used by converters and packaging producers that need high-volume, repeatable output for closures and preforms.
History and Development
Daelong states that its roots date to 1993, when the business was established in Huangyan, an area widely known in China for plastics molds and packaging machinery. Company materials emphasize long-term specialization in preform molds, cap molds, and cap compression machinery, suggesting that the firm developed as a focused supplier rather than a broad general-purpose machine builder.
A second milestone is the company’s evolution into a producer of four core high-tech product categories: high-speed precision injection molds for PET preforms, precision injection molds for plastic bottle caps, high-speed cap compression molds, and high-speed cap compression molding machines. This indicates a progression from conventional tooling toward integrated, higher-throughput systems for packaging production.
A third development milestone is the company’s continuing emphasis on independent intellectual property, mold and machine structure design, and process innovation. Public product listings also show specialized offerings such as multi-cavity cap molds and preform molds with hot runner or valve gate systems, indicating sustained product refinement for modern packaging requirements.
Business Operations and Segments
Daelong’s business is centered on two closely related segments:
- Mold manufacturing for PET preforms, bottle caps, handle molds, and other plastic packaging components.
- Cap compression and auxiliary equipment, including high-speed cap compression molding machines and related cap-forming systems.
The company is described in public listings as a manufacturer/factory and trading company, with an employee count commonly reported in the range of about 100–200 people and a plant area of about 9,000 square meters. Its registered capital is reported as 1.58 million RMB in third-party business records.
Daelong also indicates that it provides OEM/ODM service, which is consistent with a business model that combines standard product lines with customized mold design and production support for customer-specific bottle and closure formats.
Products and Technologies
Daelong’s product portfolio is built around packaging-tooling technologies used in beverage and consumer packaging production.
Core product categories
- PET preform molds for producing preforms used in blow-molded bottles.
- Bottle cap molds, including molds for water caps, edible oil caps, and other closure formats.
- Cap compression molding machines for high-speed closure production.
- Injection molds for specialized packaging components, including handle molds and cap-related tooling.
Technical characteristics
Public product listings show examples such as 8-cavity preform molds, 24-cavity cap molds, and 32-cavity cap molds, indicating a multi-cavity tooling strategy aimed at higher output and lower unit cost per part. The company also markets molds with hot runner systems and valve gate pin systems, which are commonly used to improve material flow control, reduce waste, and support higher precision in injection molding.
The company states that its molds and equipment can be supported with operator training, maintenance guidance, and a one-year warranty for molds and equipment. One product listing also advertises a mold warranty of 2 million shots, which, if achieved in practice, would be significant for high-volume packaging operations because it implies extended tooling life under controlled operating conditions.
Applications and End Markets
Daelong’s products are mainly used in plastic packaging applications, particularly where high-volume production of closures and preforms is required.
Primary end markets include:
- Beverage packaging
- Drinking water packaging
- Cosmetic packaging
- Food packaging, especially caps and closures for edible oil and other packaged products
- Broader soft packaging and closure-related plastics applications
The company’s tooling and machine portfolio is most relevant to converters and packaging producers that need standardized bottle-cap systems, PET preform production, or complete cap-forming lines.
Global Presence and Market Position
Daelong is headquartered at No. 58 Kangzhuang Road, Huangyan Economic Development Zone, Taizhou, Zhejiang, China. Huangyan is an established plastics mold cluster, and local industry reporting indicates that the district hosts a large concentration of mold and supporting equipment firms, making the region an important supply base for China’s plastics processing industries.
Third-party trade and marketplace profiles suggest that Daelong has served export markets in North America, South America, Eastern Europe, and other destinations, although those listings do not provide audited shipment volumes or market share. Import/export record summaries also indicate overseas trade activity, including transactions reported for India, which supports the view that the company participates in international packaging-equipment supply chains.
Public listings place Daelong in a competitive segment populated by other Huangyan mold makers and specialized packaging-equipment suppliers, where differentiation typically depends on tooling precision, cavity count, product life, delivery time, and after-sales service rather than brand scale alone.
Sustainability and Environmental Initiatives
Daelong’s publicly available materials do not present a detailed sustainability report or formal ESG framework. Its product line, however, is relevant to resource efficiency in plastics manufacturing because high-cavity molds, precision tooling, and cap compression systems can support higher output per cycle and potentially reduce material and energy waste per finished part compared with less optimized production setups.
At the industry level, plastic packaging remains under pressure from recycling, lightweighting, and regulatory concerns, so mold makers increasingly compete on tooling efficiency, process stability, and compatibility with lower-waste manufacturing methods. Daelong’s emphasis on precision design, hot runner systems, and high-speed machines fits that broader technical direction, although the company has not publicly disclosed quantified emissions, recycling, or circularity targets.
Financial Performance and Economic Impact
No audited financial statements, revenue figures, or profit data were identified in the available sources. The company’s economic significance is therefore best understood through its role as a specialized supplier to the packaging and mold-making value chain rather than through public financial disclosure.
Based on third-party listings, Daelong employs roughly 100–200 people and operates from a purpose-built industrial site in Huangyan. As a mid-sized tooling and machinery manufacturer, it contributes to the regional industrial base that supports bottle, closure, and packaging production in Zhejiang and beyond.
Leadership and Corporate Governance
Public records identify Lin Shouxue as the legal representative in business registry data, though the company has not publicly released a detailed governance profile or board structure. The company also appears under earlier and alternate names, including Taizhou Huangyan Hengyuan Mold & Plastic Factory and references to Deyilong or Daelong in English-language materials, indicating a naming history that is common among privately held industrial firms in China.
Available sources suggest a privately controlled enterprise structure, but they do not provide enough information to characterize ownership in detail beyond the registry-style descriptions of a limited liability company with natural-person investment or control.
Innovations and Future Outlook
Daelong’s innovation profile centers on precision tooling, multi-cavity designs, cap compression technology, and the integration of mold design with specialized forming equipment. Its stated focus on intellectual property, process innovation, and market-driven development suggests a business model aimed at incremental engineering improvements rather than large-scale platform diversification.
Future prospects for the company are likely tied to several industry trends:
- continuing demand for PET beverage packaging and closure tooling;
- customer preference for higher-cavity molds and better cycle efficiency;
- the need for more precise cap systems compatible with high-speed production lines;
- and ongoing pressure for tooling that supports lower waste and more stable manufacturing.
Given its position in Huangyan’s mold cluster and its specialization in closure and preform systems, Daelong is positioned to remain relevant where packaging manufacturers require customized mold solutions, machine integration, and local technical support.
