Introduction
SICHUAN HAIMIN TECHNOLOGY CO., LTD. (四川省海旻科技有限公司) is a Sichuan-based plastics-industry supplier headquartered in Chengdu, Sichuan, China, with public exhibitor listings describing it as a plastic and rubber supplier and indicating activity in twin-screw barrel-related products. The company appears in the Chinaplas 2026 eMarketplace as a plastics and rubber supplier and is also identified in public listings as a “specialized, sophisticated, distinctive, and innovative” enterprise, a Chinese government-recognized designation for smaller technology-oriented firms.
In the plastics machinery supply chain, companies such as Haimin are typically positioned downstream of polymer producers and upstream of processors, providing critical wear-intensive components and machine parts that affect extrusion stability, throughput, mixing quality, and service life. Available public information is limited, but the company’s exhibitor and marketplace listings suggest a focus on extrusion equipment components, especially screw-barrel systems used in twin-screw processing lines.
History and Development
Publicly accessible information on the company’s founding date, ownership structure, and early operating history is limited in the available sources. However, several dated public records and government-linked listings show that the firm has been formally recognized in China’s innovation-oriented enterprise system.
Key publicly visible milestones include:
- The company was listed in a 2024 Sichuan technology-oriented small and medium-sized enterprise roster, indicating provincial-level recognition as a technology-focused business.
- It was also included among companies issued high-tech enterprise certificates in 2024, suggesting formal certification under China’s high-tech enterprise framework.
- By 2026, the company appeared as an exhibitor on the Chinaplas eMarketplace, linking it to one of the plastics sector’s major trade and sourcing platforms.
Business Operations and Segments
The available sources do not provide a detailed segment breakdown, audited financial statements, or a complete product catalogue. Based on the marketplace and exhibitor information, the company’s business is best characterized as focused on plastics and rubber machinery supply, with emphasis on extrusion-related components.
Its likely operational profile includes:
- Component manufacturing for plastics processing machinery
- Supply of screw and barrel assemblies for twin-screw extrusion systems
- Custom or application-specific parts for polymer compounding and processing equipment
Because public documentation is sparse, these points should be understood as a conservative synthesis of the company’s marketplace presence rather than a full corporate disclosure.
Products and Technologies
The clearest public indication of the company’s technical scope is the reference to twin-screw barrel products. In plastics processing, screw-barrel assemblies are central to the performance of twin-screw extruders, which are widely used for compounding, masterbatch production, reactive extrusion, filler dispersion, and specialty polymer processing.
Likely technical focus
- Screw elements
- Barrels
- Twin-screw extrusion parts
- Wear-resistant machining components
- Custom extrusion assemblies
Technical relevance
In twin-screw processing, screw geometry and barrel precision directly affect:
- Melt homogenization
- Material conveyance
- Mixing intensity
- Residence time distribution
- Output consistency
- Energy efficiency
For suppliers in this niche, competitive value often depends on materials engineering, wear resistance, dimension accuracy, and the ability to support different polymer formulations, including filled, reinforced, and abrasive systems. The available sources do not specify the company’s alloy systems, surface treatments, or machining tolerances.
Applications and End Markets
No source in the current set provides a full list of end markets. Based on the nature of twin-screw extrusion components, the company’s products are likely relevant to processors serving:
- Compounding and masterbatch
- Engineering plastics
- Modified plastics
- Recycled polymer processing
- Additive and filler incorporation
- Specialty extrusion applications
These are typical end-use domains for screw-barrel suppliers in China’s plastics machinery ecosystem, especially in industrial regions such as Sichuan where equipment manufacturing and polymer processing are closely connected.
Global Presence and Market Position
Publicly available evidence places the company in Chengdu, Sichuan, with no confirmed overseas subsidiaries, foreign offices, or export footprint in the sources reviewed. Its market position appears to be that of a specialized component supplier rather than a large integrated machinery manufacturer.
The company’s presence on Chinaplas eMarketplace indicates participation in an established industry sourcing and exhibition environment, which is important for reaching processors, machinery builders, and procurement teams in China and broader Asian markets. The available information does not support claims of national scale, market leadership, or specific share in the extrusion-components segment.
Sustainability and Environmental Initiatives
No source in the available set provides detailed environmental reporting, emissions data, or circular-economy disclosures for the company. Nevertheless, the broader relevance of its product category is clear: durable extrusion components can support longer service intervals, reduced downtime, and lower material loss in processing operations, which are practical efficiency benefits in plastics manufacturing.
Because no verified company-level sustainability statements were found in the current sources, any further environmental claims would be speculative.
Financial Performance and Economic Impact
No audited financial data, revenue figures, or employee counts were available in the sources reviewed. The public listings do, however, indicate that the company belongs to a class of technology-oriented industrial SMEs recognized by Chinese authorities, which is often associated with specialized manufacturing capacity and local industrial contribution.
Its economic significance is likely concentrated in:
- Industrial supply-chain support for plastics processors
- Precision manufacturing employment
- Local industrial ecosystem participation in Chengdu and wider Sichuan
Leadership and Corporate Governance
The current source set does not provide verified names of directors, executives, or formal governance disclosures. Therefore, no reliable statement can be made about board composition, ownership control, or internal governance structure.
Innovations and Future Outlook
The company’s innovation profile is implied by its recognition as a specialized and innovative enterprise and by its presence in a technically demanding niche of twin-screw extrusion components. In this segment, future competitiveness generally depends on:
- Improved wear-resistant materials
- Higher-precision machining
- Application-specific screw designs
- Support for recycled and high-fill formulations
- Shorter lead times and customized service
Demand for extrusion components is likely to remain linked to broader industry trends in plastic compounding, material substitution, recycling, and process efficiency. For a company such as Haimin, the main challenge and opportunity lie in maintaining technical differentiation in a component market where reliability, durability, and service responsiveness are decisive.
Summary
SICHUAN HAIMIN TECHNOLOGY CO., LTD. is a Chengdu-based plastics-industry supplier associated with twin-screw barrel and extrusion-component products and publicly listed as a plastic and rubber supplier on industry marketplace platforms. The company appears to operate as a specialized SME within China’s plastics machinery supply chain, with publicly visible recognition in 2024 government-related technology-enterprise listings and a 2026 Chinaplas exhibitor presence.
