Aluminum Coil & SPC Board Laminating Line Solution | PURETE Flat Lamination Machine
1. Customer Business Overview
This customer is a professional manufacturer of new decorative panels, focusing on two core substrate lamination processing businesses:
Lamination of Aluminum Coils.
They process aluminum coils with thickness ranging from 0.4mm to 1.0mm, and laminate PVC, PET and PP decorative films on the surface. Finished products include all-aluminum wall panels, aluminum veneers, curtain wall aluminum coils and kitchen & bathroom aluminum decorative panels, supplying domestic and overseas whole-house customization, architectural curtain wall and integrated ceiling industries.Flat Lamination of Single SPC Boards.
Single SPC sheets with thickness of 1.2mm to 9mm are laminated to produce interior floorings, wall panels and cabinet decorative panels, featuring waterproof, fire-resistant and wear-resistant properties for home and commercial decoration.
The customer originally operated two separate production lines for aluminum coils and SPC sheets, which brought excessive manual intervention, poor processing precision, high material loss and limited production capacity. To obtain an integrated composite lamination solution, the customer finally purchased the PURETE dual-purpose roll-to-roll aluminum coil flat laminating line. A single production line supports both coiled aluminum materials and single SPC sheets, realizing fully automatic continuous production for two types of substrates.
2. Core Production Pain Points of Traditional Equipment
| Category | Defects of Traditional Machines | Production Losses |
|---|
| Substrate Compatibility Restriction | Separate machines required for aluminum coils and SPC boards; double investment on equipment and factory space | Over 50% higher costs on factory space and equipment procurement |
| Aluminum Coil Feeding Defects | Unstable tension of thin aluminum coils leads to stretching, wrinkling, deviation and material breakage during high-speed production | Scrap rate reaches 6%–10%, severe aluminum material waste |
| Low Lamination Precision | No multi-stage buffer & leveling structures, resulting in bubbles, delamination and misalignment during lamination, as well as edge glue peeling | High rework rate; high rejection risk for high-end orders |
| Mass Manual Post-processing | Manual edge trimming, secondary leveling and fixed-length cutting after lamination | 2–3 operators needed per line, high labor costs |
| Disconnected Process Links | Independent separated feeding, gluing, pressing and cutting units without rigid gantry frames, causing vibration at high speeds | Low maximum production speed, insufficient daily output |
| Lack of Dust Removal & Preheating | No static dust removal or preheating sections; dust and temperature difference on substrates reduce film adhesion | Poor lamination adhesion, frequent after-sales complaints |
3. Complete Technological Process of PURETE Custom Laminating Line
Uncoiling → Material Buffering → Leveling → Secondary Buffering → Heavy-Duty Gantry Frame Feeding → Conveying → Dust Removal → Preheating → Glue Coating → Single-Roll Lamination → Conveying with Edge Trimming → Lifting Buffer Conveying → Leveling & Cutting → Belt Conveying → Rear Gantry Frame Discharge
Function Explanation of Each Section (For Image Annotation)
Uncoiling & Double Buffer Storage: Enable non-stop coil replacement to extend continuous production time
Multi-Stage Leveling Roller Group: Eliminate internal stress of 0.4–1.0mm thin aluminum coils to avoid stretching and wrinkling
Integrated Dust Removal & Preheating: Remove static dust on panels and balance substrate temperature to boost glue adhesion
Precision Single-Roll Gluing System: Uniform controllable glue layer, less glue consumption without glue penetration or air bubbles
Online Automatic Edge Trimming: Trim excess film edges synchronously during lamination to eliminate manual polishing
Lifting Buffer Conveying: Adapt to thickness gaps between thin and thick SPC boards to prevent scratching and warping
Servo Leveling & Fixed-Length Cutting: Uniform panel flatness; cutting error within ±0.3mm with burr-free notches
Dual Heavy-Duty Gantry Frames: Suppress vibration at high running speed and maintain stable lamination precision for long-term operation
4. How PURETE Laminating Line Solves Customer Pain Points
Dual-purpose Design for Aluminum Coils & Single SPC Sheets
One single line supports 0.4~1.0mm roll aluminum and 1.2~9mm single SPC boards simultaneously. No need to purchase two separate machines, saving factory space, equipment investment and labor for maintenance.
Multi-Stage Buffer & Constant Tension Leveling System to Eliminate Wrinkling & Breakage of Thin Aluminum
Dual buffer storage plus multiple leveling rollers with closed-loop tension control ensure smooth feeding of ultra-thin aluminum coils. The scrap rate caused by stretching, wrinkling and breakage drops by 90%, greatly reducing raw aluminum waste.
Front-end Dust Removal & Preheating Integration for Superior Film Adhesion
Static dust removal and balanced substrate temperature before processing eliminate bubbling, delamination and edge peeling issues, lifting finished product yield above 98%.
Fully Automatic Post-processing: Online Trimming, Leveling & Servo Cutting
Integrated automatic lamination, edge trimming, leveling and fixed-length cutting with zero manual assistance. Only one worker is required for line supervision, cutting labor costs significantly.
Dual Heavy-Duty Gantry Frames for Stable High-Speed Operation
Thickened gantry frames at feeding and discharging ends suppress vibration during high-speed operation, preventing precision drift after long-term production and extending equipment service life.
Non-Stop Continuous Production for 40% Higher Daily Output
Buffer storage structure supports coil replacement without shutdown. Compared with traditional segmented equipment, daily production capacity increases by 40%, meeting mass overseas panel order delivery demands.
5. Advantages Comparison: PURETE Laminating Line VS Ordinary Laminating Machines from Competitors
| Comparison Item | PURETE Dual-Purpose Laminating Line for Aluminum Coil & SPC | Ordinary Single-Function Laminating Lines on Market |
|---|
| Substrate Compatibility | Compatible with 0.4–1.0mm aluminum coils and 1.2–9mm single SPC boards | Only supports either coils or single sheets; two machines required for mixed production |
| Tension & Leveling Structure | Double buffer + multi-group leveling rollers, closed-loop constant tension control | Single simple buffer without precise leveling; thin aluminum prone to wrinkling |
| Pre-treatment Section | Equipped with electrostatic dust removal + constant temperature preheating | No independent dust removal or preheating unit |
| Post-processing Automation | Built-in online edge trimming, lifting buffer and servo fixed-length cutting | Edge trimming, leveling and cutting rely on manual operation |
| Frame Structure | Front & rear heavy-duty integrated gantry frames, low vibration at high speed | Thin split frame, severe vibration leading to unstable lamination precision |
| Continuous Production Capacity | Non-stop coil changing, 40% higher daily output | Must stop production for coil replacement, low operation efficiency |
| Labor Demand | Only 1 supervisor per line | 2–3 workers needed for auxiliary processing |
| Long-Term Operation Stability | Precision deviation controlled within ±0.3mm after years of operation | Precision drifts obviously after 6–12 months of continuous use |
