The company positions itself as an integrated processor of advanced plastics rather than a commodity plastics producer. Its product range includes rods, sheets, tubes, plates, capillary tubing, filaments, and custom-machined parts, reflecting demand for high-temperature, wear-resistant, chemically resistant, and electrically insulating materials across aerospace, electronics, automotive, petrochemical, medical, and precision machinery applications.
History and Development
Nanjing Shousu was established in 2008, initially concentrating on high-end plastic parts and special engineering plastics processing. Over time, it expanded from general special-plastics work into a more specialized portfolio centered on PEEK and polyimide, which are among the most technically demanding thermoplastics used in industrial manufacturing.
The company’s development path includes several notable milestones:
- In its early operating phase, it built capabilities in extrusion, injection molding, compression molding, and machining, enabling it to supply both semi-finished forms and finished parts.
- It later expanded into material compounding and composite modification, indicating a move beyond simple conversion toward higher-value material engineering.
- Company filings and local government materials show continued investment in production capacity and equipment, including a plastics-parts processing project involving injection molding machines, extruders, compression presses, CNC lathes, machining centers, ovens, hydraulic presses, grinders, and drilling/milling machines.
By the mid-2020s, the company described itself as operating with a substantial mold inventory and a broad product catalog, underscoring a business model built on customization and small- to medium-batch industrial supply.
Business Operations and Segments
The company’s business activities center on the R&D, design, production, and sales of special engineering plastic products and profiles. Public business descriptions indicate that it also performs plastic mold design and processing, parts processing, and related technical services.
Its main operational capabilities include:
- Continuous extrusion molding
- Injection molding
- Compression molding
- Machining / CNC finishing
- Composite modification of advanced polymers
This structure allows the company to serve customers that need both raw profile materials and fully finished precision parts. In the special plastics sector, this combination is important because many applications require tight dimensional tolerances, traceability of resin grade, and performance under heat, load, or chemical exposure.
Products and Technologies
Nanjing Shousu’s core materials portfolio includes:
- PEEK (polyether ether ketone)
- PI (polyimide)
- PPS (polyphenylene sulfide)
- PEI (polyetherimide)
- PES
- PSU / PSF
- PPSU
- PBI
- PAI
The company supplies these materials in multiple forms, including:
- Rods
- Sheets / plates
- Tubes
- Capillary tubes
- Filaments
- Custom-molded or machined parts
Its technical emphasis is on high-performance polymer processing rather than standard resin compounding. For example, company materials describe PEEK grades with different reinforcement systems, including carbon-fiber-reinforced and glass-fiber-reinforced variants, along with ESD PEEK for antistatic applications. These examples indicate a product strategy aimed at improving stiffness, creep resistance, wear performance, and dimensional stability, which are key requirements in advanced industrial environments.
The company also highlights a large mold base, with sources referring to more than 1,000 mold specifications or “thousands of molds,” which suggests a broad customization capability across standard and non-standard geometries.
Applications and End Markets
Public company descriptions and related industry listings indicate that Nanjing Shousu serves a wide range of industrial sectors, including:
- Aerospace and defense
- Electronics and electrical equipment
- Precision machinery
- Petrochemical and chemical processing
- Automotive manufacturing
- Medical and health-related applications
- Instrumentation and pumps
- Compressors and large motors
- Textile, tobacco, and general machinery
These end markets are consistent with the performance profile of PEEK, PI, PPS, and related engineering plastics, which are commonly used where metal replacement, weight reduction, corrosion resistance, insulation, or thermal stability are required.
The company’s promotional and industry-listing materials also associate its products with custom parts, including items such as gear-like components, valve seats, gaskets, seals, couplings, and sleeves, reflecting the role of special plastics in tribological and precision assemblies.
Global Presence and Market Position
Nanjing Shousu describes its products as sold not only in China but also in international markets, indicating some level of export orientation. Its presence in multilingual company pages and industry exhibition listings suggests that it engages with both domestic and overseas industrial buyers.
Within China’s special engineering plastics sector, the company appears to occupy a specialized mid-sized manufacturer position focused on customization, technical processing, and profile-to-part conversion rather than bulk resin production. Public directory listings also associate it with the broader Chinese market for PEEK and polyimide producers.
The company’s location in Nanjing’s Pukou area, near the Jiangbei New District industrial zone, places it within one of the Yangtze River Delta’s more developed manufacturing and logistics environments, which supports supply-chain access and industrial customer proximity.
Sustainability and Environmental Initiatives
Publicly available information does not indicate a large corporate sustainability program in the style of multinational chemical producers. However, the company’s business model is aligned with several broader materials-efficiency trends in the plastics industry:
- Metal substitution in high-stress parts, which can reduce component weight
- Long-life materials for demanding applications, which may extend service intervals
- Precision processing, which can reduce waste in custom-part manufacturing
- Composite modification, which can improve performance without full redesign of assemblies
Local environmental filing materials show that the company has undergone project-level environmental review for plastics-part processing activities, including an investment project with equipment selection and site expansion details. Those filings indicate formal regulatory handling of manufacturing impacts, although they do not provide a full sustainability report.
Financial Performance and Economic Impact
The company does not appear to publish detailed financial statements in the available materials. External business databases list a registered capital of 22.22222 million CNY and a founding date of 2008-12-10, while local filings and company descriptions point to continued operational expansion and equipment investment.
Its economic contribution is primarily local and industrial: it supplies specialized intermediates and finished parts used in sectors that depend on advanced polymers for performance-critical applications. In that sense, the company participates in the broader shift within China toward higher-value domestic substitution in engineering plastics, especially in applications traditionally dependent on imported PEEK and related materials.
Leadership and Corporate Governance
Public records identify Qiao Wei as the legal representative in some directory data, although the company’s detailed governance structure is not fully disclosed in the available sources.
