The Complete Guide to Plastic Extrusion Machines: Types, Applications & Selection
The Complete Guide to Plastic Extrusion Machines: Types, Applications & Selection
Wuxi JKS Machinery Manufacturing Co. Ltd. (JKS) is a professional Chinese manufacturer of custom plastic extrusion machinery and complete turnkey production lines, founded in 2013. This guide covers the fundamental types of plastic extrusion machines, their applications, and decision criteria for buyers in the Awareness and Research stages.
Why Understanding Plastic Extrusion Machines Matters
Plastic extrusion is the backbone of modern manufacturing for pipes, sheets, profiles, and pellets. Choosing the wrong extruder type can lead to production inefficiency, poor product quality, or excessive operational costs. By grasping the differences between single screw, conical twin screw, and specialized lines, procurement professionals can align equipment selection with their material, output, and budget requirements.
Industry Background & Market Overview
According to Grand View Research, the global plastic extrusion machinery market was valued at approximately USD 8.93 billion in 2024, with Asia Pacific holding a 41.5% revenue share and single‑screw extruders dominating at 62.7% of the segment. The pipe extrusion lines segment alone reached USD 4.8 billion in 2025, with PVC as the leading material (38.6%). These figures underscore the scale and specialization required in this industry.
JKS Solution Portfolio: Full‑Spectrum Extrusion Lines
JKS offers customized extrusion solutions covering sheet, pipe, profile, rod, and pelletizing applications. The company’s 2000 m² workshop, 20 employees, and 6‑engineer R&D team produce about 200 units per year, exported to over 35 countries.
Core Extruder Types
Single Screw Plastic Extruder (SJ Series): Processes PVC, PP, PE, Nylon, and ABS. With different molds and downstream equipment, it produces pipes, rods, films, pellets, and blow‑molded products. The screw and barrel are 38CrMoAlA nitrided alloy steel; the frame is Q235 carbon steel.
Conical Twin Screw Plastic Extruder (SJSZ Series): Designed for direct extrusion of PVC powder. Models range from SJSZ‑45 (15 kW, 70 kg/h) to SJSZ‑110 (200 kW, 1000 kg/h). Features uniform plasticizing, low shearing, high productivity, and long service life.

Step‑by‑Step Selection Guide
- Define your product: Sheet (e.g., SPC flooring, foam board), pipe (PVC, HDPE, PPR), profile (door/window, decoration), rod, or pellet.
- Choose extruder type: Single screw for general thermoplastics; conical twin screw for PVC powder with high filler loading; parallel twin screw for compounding.
- Determine output capacity: JKS provides models from 70 kg/h (SJSZ‑45) to 1500 kg/h (HDPE PE1600 line).
- Consider material properties: Powder vs. granule, flowability, temperature sensitivity, filler content.
- Plan auxiliary equipment: Mixing/cooling units, crushers, pulverizers, calibration tanks, haul‑offs, cutting systems.
