Introduction
Nanjing Sikerun Machinery Co., Ltd. (南京斯科润机械有限公司), also known as SKR Machinery, is a Chinese plastics machinery and components manufacturer specializing in parallel twin-screw extruder parts and related spare parts. Founded in 2012, the company is based in the Lai’an Economic Development Zone in Chuzhou, Anhui Province, and operates a factory of about 25,000 square metres with a workforce of more than 100 skilled employees and a small core technical team. Its business is centered on the design, manufacture, and after-sales service of screw elements, screw shafts, barrels, dies, and related extrusion accessories, with applications across compounding, granulation, pipe, sheet, film, wood-plastic, and medical consumables extrusion lines.
In the plastics industry value chain, Sikerun occupies a niche position as a specialist supplier of extrusion wear parts and precision components rather than a full machine builder. The company states that it serves both domestic OEMs and plastics processors, and that its parts are used in equipment associated with major international and Chinese extruder brands. It also reports export sales to markets in Asia, Europe, the Americas, and Oceania, reflecting the international character of the spare-parts segment in industrial extrusion.
History and Development
Sikerun was established on 5 December 2012, entering the market during a period when China’s extrusion equipment sector was expanding alongside downstream demand for plastics compounding, recycling, and engineered materials.
A major development milestone was the creation of its manufacturing base in the Lai’an Economic Development Zone, which the company describes as the center of its production and technical operations. The facility scale and the company’s emphasis on CNC processing suggest a production model built around precision machining rather than commodity fabrication.
The company later positioned itself as a recognized specialist enterprise, stating that it has obtained ISO 9001:2015-aligned quality management certification, uses CE-compliant suppliers, and has been identified as an Anhui High-tech Enterprise and a “Shining Niche” company on Chinaplas exhibitor listings. It also reports multiple patents related to spray guns and twin-screw extrusion technology.
Business Operations and Segments
Sikerun’s business is concentrated in three closely related areas:
- Extruder core components
- Spare-part manufacturing and replacement
- Technical services for measurement, surveying, and process support
The company says it provides parts replacement services for both domestic and international extruder brands, while also offering surveying and mapping services for accessories used in extrusion machinery. This model is typical of the aftermarket for twin-screw systems, where screw geometry, wear resistance, and dimensional precision are critical to throughput stability, mixing quality, and service life.
Products and Technologies
Sikerun’s core product range includes the following:
| Product category | Typical role in extrusion systems |
|---|---|
| Twin-screw extruder screw elements | Provide conveying, shearing, mixing, and kneading functions in compounding and granulation |
| Screw shafts and spline shafts | Transmit torque and support modular screw assembly |
| Barrels | Enclose the screw assembly and provide heating/cooling and process containment |
| Dies and liquid-injection nozzles | Shape output and enable additives or liquids to be introduced into the process |
| Hydraulic screen changers and related accessories | Support filtration and melt clean-up in extrusion lines |
The company says its screw elements are available in sizes from approximately φ8 mm to φ335 mm and are designed for self-cleaning, wear resistance, corrosion resistance, and durability. It also states that powder-alloy and high-speed-steel materials are processed with European HIP technology and heat-treated according to European methods, with CNC machining used to maintain dimensional tolerances.
From an engineering perspective, these capabilities matter because twin-screw extruders are highly sensitive to screw profile, metallurgy, and clearance control. In practice, better wear and corrosion resistance can improve service life in abrasive or chemically aggressive formulations, while tighter machining tolerances support stable compounding and more predictable output quality.
Applications and End Markets
Sikerun identifies its application areas as including:
- Pipe extrusion lines
- Granulation extrusion lines
- Wood-plastic extrusion lines
- Film extrusion lines
- Plate and sheet extrusion lines
- Food packaging container extrusion lines
- Medical consumables extrusion lines
Other exhibitor materials also mention use in plastics masterbatch, rubber-plastic systems, cable compounds, powder coatings, and related industries. These end markets depend heavily on twin-screw technology because of its ability to mix additives, fillers, colorants, and polymers with relatively high dispersion quality.
Global Presence and Market Position
Sikerun describes itself as supplying components to a broad base of customers in China and abroad. The company states that its parts are used by many domestic extruder manufacturers in Nanjing and that it exports to countries and regions including Poland, Japan, Israel, Taiwan, Thailand, Singapore, South Korea, New Zealand, Australia, Turkey, the United Kingdom, the United States, Mexico, Russia, and Brazil.
Third-party exhibitor profiles also indicate overseas exhibition presence, including listings tied to regional plastics trade shows in Southeast Asia. In the extrusion spare-parts market, this kind of international reach is significant because replacement parts are often sourced globally, and compatibility with established machine brands can widen the addressable market.
Sustainability and Environmental Initiatives
Publicly available company information does not provide a detailed sustainability report or quantified emissions targets. However, Sikerun’s business is indirectly connected to environmental performance in the plastics industry because twin-screw extrusion components are often used in recycling, compounding, and material recovery applications where process stability and wear resistance can reduce downtime and parts replacement frequency.
The company’s emphasis on durable, corrosion-resistant components and precision machining may also support longer operating life for industrial equipment, which can reduce the frequency of replacement in service-intensive operations. No verified public information reviewed here indicates formal climate targets, recycled-material content claims, or lifecycle assessment disclosures.
Financial Performance and Economic Impact
Sikerun states that its annual output value exceeds 10 million dollars and that it employs more than 100 workers. It therefore appears to be a mid-sized specialist manufacturer rather than a large integrated machinery group.
Its economic role lies mainly in the industrial supply chain for extrusion equipment, where local machining capability, aftermarket support, and compatibility with major extruder brands help reduce lead times and downtime for processors and OEMs. The company’s activity also reflects the broader strength of China’s machinery ecosystem, in which specialized parts suppliers support a large installed base of plastic processing equipment.
Leadership and Corporate Governance
Publicly available source material reviewed for this article does not provide a detailed leadership roster or board structure. The company presents itself as technically oriented, with a core team of five technicians and a broader base of experienced skilled workers.
Its published corporate messaging emphasizes technology-driven and quality-driven operations, suggesting an internal governance model centered on manufacturing discipline, process control, and customer service rather than large-scale corporate complexity.
Innovations and Future Outlook
Sikerun’s innovation profile is built around precision wear parts, material engineering, and customized service for extrusion systems. Its patent references and emphasis on high-wear, high-corrosion components indicate continued investment in incremental technical improvements rather than platform-scale machine development.
Future opportunities for the company are likely tied to several industry trends:
- Growth in plastics recycling and reprocessing, which increases demand for wear-resistant compounding components
- Expansion of engineering plastics, masterbatch, and functional compounds, which require more demanding screw designs
- Continued demand for aftermarket replacement parts in installed extrusion fleets
- Greater need for shorter lead times and local technical support in a globally fragmented supply chain
