PVC Edge Banding Machine
Product Overview
The PVC Edge Banding Extrusion Line produces thin PVC strips (0.3-3mm thick, 9-180mm wide) used for finishing exposed edges on furniture, cabinets, and panel products. Edge banding is a high-volume, high-speed product category where production efficiency and surface quality are paramount.
This versatile line is available in single-screw (SJ-65) or conical twin-screw (SJSZ-51/105) configurations, with production speeds reaching 15-30 m/min — significantly faster than structural profile lines. The line includes a precision T-die for uniform thickness, multi-color online printing, and a winding system with tension control for producing rolls up to 500 meters.
PVC edge banding requires excellent color consistency, surface smoothness, and flexibility for application on curved edges. Our precision T-die design ensures thickness tolerances within ±0.02mm, while the multi-zone temperature control system maintains consistent material rheology throughout the production run.
The integrated printing system supports up to 3-color wood grain or decorative pattern printing, enabling manufacturers to produce custom-matched edge banding for any furniture surface. Quick-change printing cylinders allow rapid pattern changes to serve custom order requirements.

Production Process
From raw material to finished product — each step is engineered for quality and efficiency.
Material Preparation
PVC compound with high plasticizer content for flexibility, pigments for color matching, and UV stabilizers. Mixed and pelletized or used as dry blend depending on extruder type.
Extrusion through T-Die
Material is extruded through a precision T-die that creates a thin, uniform strip. Die gap is adjustable for different thicknesses (0.3-3mm).
Calendering & Cooling
The strip passes through chrome-plated calender rolls that control thickness and surface finish, then through a water cooling tank for solidification.
Online Printing
Multi-color gravure printing applies wood grain, metallic, or custom patterns. UV-curing or hot air drying fixes the print instantly.
Embossing (Optional)
A heated embossing roll can apply wood grain texture synchronized with the printed pattern for realistic tactile finish.
Winding & Packaging
The finished edge banding is wound onto cores with precise tension control. Roll lengths of 100m, 200m, or 500m are standard for different market segments.

Why Choose Wings Plastic
Ultra-Precision T-Die
Adjustable lip T-die with ±0.02mm thickness tolerance ensures consistent band thickness — critical for automatic edge banding machines used by furniture manufacturers.
High-Speed Production
Production speeds of 15-30 m/min deliver 3-5 times the output of standard profile lines, making edge banding one of the most profitable PVC extrusion products per meter.
Multi-Color Printing
Integrated 3-color gravure printing system produces realistic wood grain and custom patterns in a single pass, eliminating offline printing operations.
Tension-Controlled Winding
Precision winding system with automatic tension adjustment produces uniform rolls without stretching or wrinkling — essential for smooth unwinding at customer facilities.
Dual Extruder Option
Available with single-screw (for pelletized compound) or conical twin-screw (for dry blend) — choose based on your material supply and cost structure.
Quality Assurance
Every production line undergoes rigorous quality verification before delivery:
- Online thickness measurement with beta gauge ensures ±0.02mm tolerance
- Color matching against Pantone or customer samples using spectrophotometer
- Surface finish inspection for gloss level, print clarity, and embossing depth
- Flexibility test to ensure band can wrap around 20mm radius without cracking
Typical Applications
Frequently Asked Questions
The line handles thicknesses from 0.3mm to 3mm. For thinner bands (0.3-1mm), a single-screw extruder with T-die is recommended. For thicker bands (1-3mm), either configuration works well.
Color changes take 15-30 minutes (purging and stabilizing). Pattern changes (printing cylinders) take 20-30 minutes. We recommend grouping production by color to minimize changeover time.
The extruder and die can process ABS and PMMA/acrylic materials with minor screw and temperature adjustments. However, the line is optimized for PVC. For dedicated ABS production, we recommend a separate line.
Standard roll lengths are 100m for small workshops, 200m for mid-size furniture factories, and 500m for large-scale automated production lines. The winding system can be set for any length.
