Introduction
ZHOUSHAN DINGHAI XUTAI MACHINERY CO., LTD. is a Chinese manufacturer associated with the screw and barrel segment of the plastics machinery industry, a core component category used in extrusion, injection molding, and related polymer-processing equipment. The company is based in Dinghai District, Zhoushan, Zhejiang Province, an industrial cluster widely recognized for screw-barrel manufacturing and other plastics machinery supply-chain activity.
Available business-directory and industry-exhibition records indicate that Xutai operates in the market for processing-machine parts and assemblies, with emphasis on components for parallel twin-screw, conical twin-screw, and single-screw machinery, as well as barrels and related wear parts used in plastic, rubber, chemical fiber, and injection applications. In industry terms, such products are upstream enabling components rather than finished processing lines, and they are essential to melt conveyance, mixing, pressure generation, and wear resistance in polymer-processing systems.
The company’s position reflects the broader specialization of the Zhoushan region, where many firms supply screws, barrels, and accessory parts to domestic and export customers serving plastics conversion, rubber processing, and fiber-related manufacturing. While public information on Xutai itself is limited, the company appears to participate in the plastics supply chain as a component supplier rather than as a maker of complete molding machines or turnkey plants.
History and Development
Publicly accessible records provide only limited historical detail, but several points can be established.
- The company is registered in Zhejiang Province and appears in local enterprise and industrial listings tied to Dinghai District, indicating an established manufacturing presence in the Zhoushan screw-and-barrel cluster.
- Business and professional profile data associate the company or its personnel with more than 15 years of experience in manufacturing parallel and conical twin-screw barrels, single-extruder screws, and screws and barrels for injection, rubber, and chemical fiber machinery.
- The company is listed in Chinaplas’s exhibitor marketplace, showing participation in the plastics industry’s major trade-exhibition ecosystem and suggesting active commercial engagement with processors, distributors, and machinery buyers.
Business Operations and Segments
Xutai’s publicly visible activity centers on the manufacture of screws and barrels for polymer-processing equipment. Based on the available listings, its business can be understood in three practical segments:
- Extrusion components for single-screw and twin-screw extruders.
- Injection and rubber machinery parts, where screw-barrel wear resistance and dimensional precision are critical to stable processing.
- Chemical-fiber-related screw and barrel products, which generally require attention to throughput, temperature control, and material compatibility.
The company appears to operate as a parts manufacturer within a highly specialized regional supply chain rather than as a vertically integrated builder of complete plastics machinery systems.
Products and Technologies
The most specific product information available identifies Xutai as a maker of parallel twin-screw barrels, conical twin-screw barrels, and single-extruder machine screws, along with components for injection, rubber, and chemical fiber machinery. In the plastics machinery sector, these products are typically engineered around wear life, corrosion resistance, and stable metering performance.
Key technical characteristics commonly associated with this product class include:
- Parallel twin-screw systems, used where controlled compounding, mixing, and devolatilization are important.
- Conical twin-screw systems, widely used in PVC and other formulations that benefit from strong conveying and mixing behavior.
- Single-screw screws and barrels, used in general extrusion and a broad range of polymer-processing operations.
- Wear-resistant barrel and screw surfaces, often critical in formulations containing fillers, glass fiber, pigments, or abrasive additives.
Because no detailed catalogue or product specification sheet was visible in the provided sources, specific material grades, hardfacing methods, or tolerance claims cannot be verified from the available evidence.
Applications and End Markets
Xutai’s product scope suggests exposure to several end markets in polymer processing:
- Plastics extrusion, including compounding and profile or pipe-related processing.
- Injection molding, where screw and barrel assemblies affect plasticization, metering, and shot consistency.
- Rubber processing, which places demanding wear and thermal requirements on screws and barrels.
- Chemical fiber equipment, a specialized application where process stability and material handling performance are important.
These applications place the company in a supplier role supporting downstream manufacturers that convert polymer feedstocks into finished goods for construction, packaging, consumer products, industrial parts, and fiber-based applications.
Global Presence and Market Position
Publicly available information does not provide a verified export map, revenue figure, or audited market share for Xutai. What can be established is that the company is embedded in Zhoushan’s screw-and-barrel manufacturing base, a locality that hosts numerous comparable manufacturers serving the plastics machinery market.
The company’s presence in the Chinaplas exhibitor ecosystem indicates commercial visibility within the broader Asian plastics industry, where component suppliers compete on machining capability, durability, lead time, and customization rather than on brand scale alone. The regional cluster context is significant because Zhoushan and nearby Dinghai/Jintang have long been associated with plastics machinery parts production and supplier specialization.
Sustainability and Environmental Initiatives
No company-specific sustainability report or environmental program was identified in the provided sources. On a sector basis, screw-and-barrel manufacturers are indirectly affected by industry-wide pressure to improve energy efficiency, material utilization, and equipment longevity, since longer service life and better process stability can reduce waste and downtime in downstream plastics conversion.
Given the absence of verified disclosures, no claim can be made about Xutai’s use of recycled materials, emissions reduction measures, or formal environmental certifications.
Financial Performance and Economic Impact
No audited financial statements or detailed revenue figures were available in the supplied sources. A local government record indicates the company is a recognized manufacturing enterprise in Zhejiang Province, which supports the view that it contributes to regional industrial employment and the specialized equipment-supply economy around Dinghai and Zhoushan.
As with many small and mid-sized component manufacturers in this sector, the company’s economic role is likely tied to:
- regional machining and fabrication employment,
- local procurement of metals and tooling,
- downstream supply to plastics machinery assemblers and processors,
- trade participation through industry exhibitions and B2B platforms.
Leadership and Corporate Governance
Publicly accessible sources do not provide a full management profile, board structure, or governance statement for Xutai. A LinkedIn profile associated with Angel Chu states experience in manufacturing screw and barrel products for more than 15 years, but the source does not by itself establish formal corporate office, ownership, or governance status.
Accordingly, only limited governance information can be verified from the available material.
Innovations and Future Outlook
The company’s future prospects are closely tied to broader plastics-industry trends affecting screw-barrel suppliers:
- demand for higher wear resistance and longer component life,
- need for customized screw designs for complex polymers and filled compounds,
- continued replacement demand in extrusion and injection equipment installed across Asia,
- competition based on precision manufacturing, response time, and cost efficiency.
In the absence of company-specific R&D disclosures, it is not possible to confirm proprietary technologies or new-product pipelines. However, the company’s product profile suggests that future competitiveness will depend on machining precision, metallurgical capability, and the ability to serve multiple process categories from a specialized manufacturing base.
