Industry Context: Growing Demand for Versatile Extrusion Solutions

The global plastic extrusion machinery market was valued at approximately USD 8.93 billion in 2024 and is projected to reach USD 11.58 billion by 2030, according to Grand View Research. Asia Pacific accounted for 41.5% of the market in 2024, with China as the leading contributor. Meanwhile, the pipe extrusion lines market reached USD 4.8 billion in 2025 (PVC representing 38.6% of the segment), and the Stone Plastic Composite (SPC) flooring market is expected to grow from USD 6.4 billion in 2026 to USD 10.3 billion by 2033 (Dataintelo, Grand View Research). These trends reflect increasing demand for high-performance plastic extrusion machinery across construction, infrastructure, and interior decoration sectors.

Technical Foundation: Robust Screw and Barrel Construction

Across all extrusion equipment, JKS employs 38CrMoAlA nitrided alloy steel for the screw and barrel, ensuring wear resistance and longevity. The machine frames are fabricated from Q235 carbon steel. Key extruder types include:

• Conical Twin Screw Extruder (SJSZ series): 7 models from SJSZ-45 (15 kW, 70 kg/h) to SJSZ-110 (200 kW, 1000 kg/h). Designed for direct PVC powder extrusion, offering uniform plasticizing and mixing with low shearing.
• Single Screw Extruder (SJ series): Custom options SJ30 to SJ90, suitable for PVC, PP, PE, Nylon, ABS. Versatile for pipes, rods, films, pellets, and blow-molded products.

Application Scenarios Across Industries

JKS extrusion lines serve diverse production environments globally:

• SPC Flooring Manufacturing (Product 4630): Operates in indoor high-temperature, high-pressure conditions. The SPC line produces rigid core boards (1–10 mm thickness, 980/1250 mm width) with EIR in-line embossing. Output ranges from 15 to 40 tons per 24 hours. The SPC flooring market is projected to grow from USD 6.4 billion to USD 10.3 billion by 2033, making this line a strategic investment for flooring producers.
• PVC Imitation Marble Sheet Production (Product 4632): Sheet thickness 1–12 mm, effective width 1220 mm, output 400–700 kg/h. Used in wall panels, hotel/KTV decoration, and floor decorative sheets.
• PP Hollow Construction Formwork (Product 4635): Produces recyclable formwork panels (1220 mm width, 15–20 mm thickness) with double-sided UV coating option. Daily output 420–480 panels per 24 hours.
• WPC Door Panel Extrusion (Product 4720): Models SJSZ80 (75 kW, 250–400 kg/h) and SJSZ92 (110 kW, 400–600 kg/h) for interior door manufacturing.
• Corrugated Pipe Line (Product 4711): KSPG series for small pipes (6–63 mm) and KS series for larger diameters (50–160 mm). Used for wire threading, drainage, and cable protection.

Market Trend: Sustainability and Customization

Plastic recycling and sustainable production are reshaping the industry. The waste plastic washing and pelletizing recycling lines market was valued at USD 5.502 billion in 2024. JKS offers dedicated recycling solutions: the two-stage strand cutting pelletizing line (ST series, throughput 70–650 kg/h) and the PVC hot-cut pelletizing line (SJSZ55 to SJSZ92, output 100–800 kg/h). These allow producers to convert scrap into high-quality pellets, aligning with circular economy goals.

Single-screw extrusion machines held 62.7% market share in 2024, while twin-screw types dominate PVC compounding. JKS covers both technologies, enabling buyers to match capacity and material requirements precisely.

Comparison with Traditional Lines

Traditional plastic extrusion lines are often standardized, limiting formulation flexibility. JKS provides personalized design, free factory installation, and technical training based on the client’s raw material and production needs. An honest limitation: as a mid-sized Chinese manufacturer with 20 employees, JKS may have longer lead times for highly complex custom molds compared to larger global players like Coperion or KraussMaffei. However, for buyers seeking cost-effective, tailor-made lines with strong R&D support, JKS offers a compelling balance of customization and value.

Future Outlook

The plastic extrusion machinery market will continue expanding, driven by infrastructure growth in Asia Pacific and the replacement of traditional materials with composites. JKS’s investment in turnkey solutions and the expansion of its product range (including steel wire reinforced composite pipe and large-diameter HDPE pipe lines) positions it well for increasing project-based procurement. Buyers in the evaluation stage should prioritize machinery that offers material adaptability, after-sales support, and compatibility with future formulation changes.
