A plastic extrusion machine specification sheet is not a marketing document. It is a set of engineering constraints that determines whether a line can process your raw material, reach your target output, hold your required product dimensions, and pass your compliance review. This guide explains how to read those constraints, and how Wuxi JKS Machinery Manufacturing Co. Ltd. documents its own plastic extrusion machine line parameters for buyers in the Research and Evaluation stage.

Wuxi JKS Machinery Manufacturing Co. Ltd. is a Chinese manufacturer specializing in custom plastic extrusion machinery and complete turnkey production lines. Founded in 2013, the company designs and builds plastic sheet, SPC flooring, WPC foam board, plastic pipe, PVC/WPC profile, solid plastic rod, and waste plastic recycling lines, and has exported equipment to more than 35 countries.

What “Specification” Really Means in Plastic Extrusion Buying

Most extrusion machine inquiries fail because the buyer and supplier are not comparing the same specification groups. A useful plastic extrusion machine specification should cover at least six areas:

• Extruder type and model
• Motor power and screw geometry
• Output capacity
• Finished product dimensional range
• Raw material compatibility
• Downstream line configuration and compliance evidence

Without these six groups, a line description is incomplete. For a constrained buyer, missing parameters create project risk: the line may produce a similar product, but not your product.

Market Context: Why Parameters Matter More in 2026

Market data helps explain why buyers are moving from feature-based comparisons to parameter-based comparisons. 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 held a 41.5% revenue share in 2024, with China as the leading contributor in the region. The global pipe extrusion lines market is valued at USD 4.8 billion in 2025, with PVC as the leading material segment at 38.6%.

The same trend appears in downstream applications. The Stone Plastic Composite (SPC) flooring market is projected to grow from USD 6.4 billion in 2026 to USD 10.3 billion by 2033, driven by a 7.2% CAGR. Single-screw extrusion machines held about 62.7% of the global extrusion machinery market in 2024, while PVC-based building material lines more often use conical twin-screw extruders because those machines process powder compounds directly.

These figures are relevant because they show the direction of demand: construction materials, pipe networks, and flooring products are growth categories. Buyers entering these categories need verified specifications, not vague promises.

Key Specification Groups for JKS Plastic Extrusion Machines

Extruder Type: Conical Twin Screw vs Single Screw

JKS offers both conical twin-screw extruders (SJSZ series) and single-screw extruders (SJ series). Conical twin-screw models are documented for direct extrusion of PVC powder for pipes, sheets, bars, profiles and other products. Models range from SJSZ-45 (15 kW, 70 kg/h) to SJSZ-110 (200 kW, 1,000 kg/h). Single-screw models such as SJ30, SJ45, SJ65 and SJ90 process PVC, PP, PE, Nylon and ABS, and produce pipes, rods, films, pellets and coated products depending on the mold set.

The choice between the two geometries is not a quality ranking; it is a material constraint. PVC-based compounds with high filler content run more efficiently on conical twin-screw machines, while single-screw machines give processors flexibility across multiple thermoplastics.

Output and Capacity

Output is the specification most frequently used as a headline figure, but it must be tied to a specific line configuration. JKS documents the following output ranges:

• SPC Flooring Extrusion Line: 15–40 tons per 24 hours, depending on extruder model
• PVC Imitation Marble Sheet Extrusion Line: 400–700 kg/h
• PP Hollow Construction Formwork Extrusion Line: 180–250 kg/h (SJ90) and 500–600 kg/h (SJ130), equivalent to 420–480 pieces per 24 hours
• PVC Hollow Wall Panel & Ceiling Extrusion Line: 120–400 kg/h by model
• PVC Water Supply & Drainage Pipe Extrusion Line: 270 kg/h (PVC63), 450 kg/h (PVC250), 800 kg/h (PVC630)
• HDPE Water Pipe Extrusion Line: 150–400 kg/h (PE110) up to 600–1,500 kg/h (PE1600)
• PPR Pipe Extrusion Line: 80–160 kg/h (PPR20-75) and 80–250 kg/h (PPR20-110)
• Corrugated Pipe Extrusion Line: haul-off speed from 5 to 20 m/min across five models

Product Dimensional Range

Product dimensions define the usable envelope of the line:

• SPC Flooring Extrusion Line: finished thickness 1–10 mm, effective width 980 mm or 1,250 mm
• PVC Imitation Marble Sheet: thickness 1–12 mm, effective width 1,220 mm
• PP Hollow Construction Formwork: width 1,220 mm, thickness 15–20 mm, round-hole hollow structure, ABA three-layer structure
• PVC Hollow Wall Panel: product width 300 mm to 1,200 mm depending on model
• HDPE Water Pipe: diameters from Φ20 mm to Φ1,600 mm across five line types
• PVC Water Supply & Drainage Pipe: Φ16–63 mm (PVC63), Φ90–250 mm (PVC250), Φ315–630 mm (PVC630)
• Steel Wire Mesh Reinforced Composite Pipe: Φ50–630 mm across five line models
• Solid Plastic Rod: Φ6–60 mm (SJ45) and Φ30–200 mm (SJ65)

Raw Material Compatibility

Material compatibility is a constraint that cannot be changed later. Documented examples include:

• PVC + CaCO₃ compound: SPC flooring, imitation marble sheet, hollow wall panel, foam board, door panel, grille profile
• PP recycled granule (MFI < 3): hollow construction formwork
• PP / PE / PA / POM: solid plastic rod
• PE / PP / ABS / PS / HIPS / PC: strand cutting pelletizing lines
• PVC powder / PVC scraps: hot-cut pelletizing lines
• MPP / PE, optional PP / ABS / PEX / silicon core pipe: high voltage power pipe lines
• PP / PE / PVC / PS / PC / ABS: multi-material profile lines

Downstream Configuration and Line Footprint

A plastic extrusion machine line is not only the extruder. JKS documents complete downstream systems:

• Multi-material profile line: feeding system → single screw extruder → calibrating table → cooling tank → haul-off → fixed-length cutting
• PVC water pipe line: vacuum calibration, multi-claw traction, dust-free cutting unit
• SPC line: vertical or inclined four-roller calender, optional EIR in-line synchronous wood grain embossing
• PP formwork line: overall machine dimension 34 m × 7 m × 4.5 m, 380V/50Hz/3-phase power supply, optional double-sided UV anti-aging coating, channel smoothness 0.015–0.03 μm

For PP formwork, the full-line footprint affects factory layout. The documented 34 m × 7 m × 4.5 m dimension should be checked before civil works begin.

JKS also supplies auxiliary equipment for complete compounding and recycling workshops: SP400/SP660 plastic crushers (300–700 kg/h), MF400/MF500/MF600 pulverizers (200–500 kg/h, 40–80 mesh), and SRL-Z hot/cold mixing units (300–2,000 kg/h).

Compliance Evidence: The CE Documentation

Compliance is a specification constraint. JKS plastic extrusion lines are documented under CE certification, with certificate number M.2021.206.C.64011 issued by UDEM International Certification Auditing Training Centre, in accordance with EN ISO 12100:2010. The scope includes the SJSZ series, SJ series and SJP series models and applies to the global market.

Buyers in the EU and other regulated markets should request a copy of the certificate and the declaration of conformity during the quotation stage.

How to Verify a Specification: A 7-Step Check for Constrained Buyers

1. Define the end product and raw material first. A line cannot be selected before the product and material are fixed. For a PVC pipe producer, the deciding parameters are diameter range, wall thickness, and whether the compound is powder-based or pellet-based.
2. Calculate your required output per day and compare it with the line’s documented kg/h or tons/24h.
3. Match the extruder model to the material form. Powder compound → conical twin screw; pellet or multi-resin → single screw.
4. Check the product dimensional envelope against the documented width or diameter range.
5. Confirm the downstream units for your finishing requirement: calibration, cooling, haul-off, cutting, embossing or stacking.
6. Review compliance evidence. Certificate number, issuing body, applicable standard and scope should all be stated.
7. Ask about factory pre-assembly and testing. JKS documents 100% factory pre-assembly and testing before shipment, which is one of the most valuable checks a buyer can make.

Documented Use Cases: Specifications in Long-Term Operation
