Introduction
Taizhou Huangyan Kelong Plastic & Mould Co., Ltd. (台州市黄岩科隆塑模有限公司) is a Zhejiang-based Chinese manufacturer specializing in plastic injection moulds and related plastic product manufacturing. The company is located in Huangyan, Taizhou, an area widely associated with China’s mould industry, and its published product range includes moulds for crates, chairs, pallets, baskets, buckets, pet products, auto parts, home appliances, and other daily-use plastic goods.
Kelong operates as a manufacturer/factory and trading company, with OEM/ODM capabilities advertised on multiple industry platforms. Its business model combines mould design and production with downstream plastic product support, positioning it within the broader ecosystem of Chinese mould makers that serve consumer goods, logistics, furniture, home appliance, and industrial applications.
History and Development
Kelong’s publicly available registration information indicates that the company was established on 18 April 2018 in Huangyan District, Taizhou. Its corporate registration details identify it as a limited liability company with operations centered on moulds, plastic products, raw materials, hardware, machinery parts, auto parts, and related trade activities.
Company and marketplace profiles show that Kelong has built its business around custom injection mould development, including product design, mould manufacture, and production verification for customer projects. Its listed experience in mould categories such as chair moulds, crate moulds, bucket moulds, and household items suggests a development path focused on high-volume commodity moulding rather than a narrow specialty niche.
Public listings also describe a broader operational expansion through export-oriented sales channels in regions including Europe, South America, the Middle East, North Africa, and Southeast Asia. These references indicate that, despite its relatively small workforce in some directory listings, the company presents itself as serving international customers through OEM/ODM production support.
Business Operations and Segments
Kelong’s activities can be grouped into the following areas:
- Injection mould manufacturing
- Plastic product processing
- Mould design and development
- OEM/ODM project support
- International trade in mould-related products and materials
The company’s business scope in Chinese registration data includes plastic products, moulds and accessories, plastic raw materials, rubber products, auto parts, hardware accessories, machinery equipment and accessories, and steel products. This suggests a vertically adjacent operating model that links tooling, materials, and product delivery.
Its published product categories show a strong concentration in commodity moulds and large injection moulds, particularly for household and logistics applications such as chairs, baskets, crates, pallets, trash cans, and storage products. The company also advertises moulds for home appliances, thin-wall containers, auto parts, and pet products, reflecting a diversified but still largely mass-market portfolio.
Products and Technologies
Kelong’s product information emphasizes plastic injection moulds for common high-volume articles rather than highly specialized engineering components. Representative product lines include:
- Plastic crate moulds
- Plastic chair moulds
- Plastic pallet moulds
- Plastic basket moulds
- Plastic bucket moulds
- Trash can moulds
- Disposable cup lid moulds
- Storage and tray moulds
- Pet product moulds
- Auto parts moulds
- Home appliance moulds
The company’s listings indicate capability in large-scale injection moulds and high-precision mould making. Technical equipment cited in supplier directories includes Sodick mirror EDM, wire cutting machines, 5-axis machining centers, and mould clamping machines, which are relevant to precision cavity finishing, complex geometry machining, and mould assembly validation.
Several product pages mention use with materials such as HDPE and applications in single-cavity mould configurations for items like sanitation trash cans. Other listings refer to thin-wall moulds, double-color overmoulding, and moulds for containers and household items, which imply experience in tooling for dimensional stability, cycle-time efficiency, and repeatable mass production.
The company also states service commitments such as one-year warranty, lifelong technical service, and die life above 500,000 cycles on its own website. These claims are company-provided and should be understood as marketing statements unless independently audited, but they indicate the performance criteria Kelong uses to position its tooling business.
Applications and End Markets
Kelong’s moulds are primarily used in the following end markets:
- Household goods
- Furniture and seating
- Logistics and storage
- Food and beverage packaging components
- Home appliances
- Outdoor and sanitation products
- Pet products
- Selected auto parts and industrial components
The company’s strongest visible market presence is in commodity plastic articles, such as chairs, crates, buckets, baskets, and storage items. These products are typically produced in large volumes and require moulds optimized for durability, consistent cooling, and efficient demoulding.
Some listings also link Kelong to household appliance moulds and thin-wall packaging-related moulds, indicating participation in segments where cycle time, surface quality, and part consistency are critical. In addition, product examples such as pen container moulds, coffee cup lid moulds, and grid tray moulds show that the company serves both consumer and utility-oriented plastic applications.
Global Presence and Market Position
Available company profiles describe Kelong as exporting or serving customers in more than 30 countries and regions, with sales channels stated for Europe, South America, the Middle East, North Africa, Southeast Asia, the United States, and parts of China. These references indicate an export-facing business model, though they are self-reported or directory-based rather than independently audited trade statistics.
The company’s market positioning is that of a specialized mould maker in Huangyan, a district long associated with mould and tooling concentration. Within that ecosystem, Kelong appears to focus on custom mould solutions for commodity and household plastics, competing on design responsiveness, tooling capability, and customer service rather than on scale comparable to major multinational mould groups.
Directory listings vary on company scale, with some profiles describing about 17 employees and others stating more than 120 employees, 28,000 square meters of coverage, and an annual output value above 68 million yuan. Because these figures are inconsistent across sources, they should be treated cautiously; the most defensible conclusion is that Kelong is a relatively small-to-mid-sized private mould producer whose online presence emphasizes international sales and high-precision capability.
Sustainability and Environmental Initiatives
Publicly available material for Kelong does not provide detailed, independently verified sustainability reporting. The company’s visible business focus is conventional injection mould production for durable and disposable plastic goods, a sector that is directly affected by broader industry pressure on material efficiency, recyclability, and product life-cycle impacts.
From an industry perspective, mould makers serving logistics and household segments are increasingly expected to support lighter-weight designs, reduced scrap, and improved production efficiency. Kelong’s emphasis on precision tooling, mould life, and technical service is consistent with operational approaches that can reduce downtime and material waste, although the company has not published detailed environmental metrics in the sources reviewed.
Financial Performance and Economic Impact
No audited financial statements were identified in the available sources. One supplier profile states an annual turnover exceeding USD 5 million, while another directory lists an annual output value of more than 68 million yuan. These figures are not directly comparable and likely come from different self-reported profiles or time periods.
Kelong’s economic role is primarily as a local manufacturer and export supplier in Huangyan’s mould cluster. Its activity supports downstream plastic conversion, tooling, maintenance, and trade services, which are important employment and industrial linkages in regional manufacturing ecosystems.
Leadership and Corporate Governance
Chinese business registry-style information identifies Luo Jian as the legal representative and lists the company as a limited liability company. Other directories name sales contacts, but no detailed board structure or governance disclosure was located in the reviewed sources.
The company’s registration data indicates a legal business scope extending beyond moulds into plastics, machinery, hardware, and trade, suggesting a diversified small-enterprise governance structure typical of privately held manufacturing firms in the region.
Innovations and Future Outlook
Kelong’s public materials indicate continued emphasis on custom mould development, production verification, and one-stop support from mould design to finished plastic product processing. Its use of precision machining equipment and its focus on large injection moulds suggest that future competitiveness will likely depend on tool longevity, dimensional accuracy, faster development cycles, and broader customer support across export markets.
Future growth in this type of business will likely depend on several industry trends:
- rising demand for durable logistics and storage moulds
- continued outsourcing of custom mould fabrication
- demand for lighter, more material-efficient plastic parts
- stronger requirements for quality consistency in export markets
- adaptation to environmental and regulatory pressure on plastics production
Summary
Taizhou Huangyan Kelong Plastic & Mould Co., Ltd. is a Huangyan-based mould manufacturer focused on plastic injection moulds and related plastic product solutions. Its portfolio centers on commodity and household applications, supported by OEM/ODM services, precision machining equipment, and export-oriented sales channels.
