Building Facade Aluminum PVC Aluminum Panel

1. Product Overview

Building Facade Aluminum PVC Aluminum Panel, is a high-performance sandwich-structured material consisting of two pre-painted aluminum sheets bonded to a rigid PVC (Polyvinyl Chloride) foam core. This innovative composite material combines the excellent properties of aluminum (lightweight, corrosion resistance, processability) with the advantages of PVC foam (thermal insulation, sound absorption, cost-effectiveness), creating a versatile building and decorative material widely used across multiple industries.

3. Product Advantages

3.1 Structural & Mechanical Benefits

· Lightweight & High Rigidity: 30-50% lighter than solid aluminum sheets while maintaining excellent structural stability, reducing transportation and installation costs by 20-30%

· Superior Dimensional Stability: Symmetrical sandwich structure minimizes thermal expansion/contraction effects, preventing warping or buckling under temperature variations (-40°C to +80°C)

· Exceptional Flatness: Maintains smooth surface across large panels (up to 6m length), eliminating waviness issues common with single-skin aluminum

3.2 Performance Advantages

· Excellent Thermal Insulation: PVC foam core provides superior thermal resistance, reducing building energy consumption by 15-20% compared to traditional materials

· Enhanced Sound Absorption: Effectively reduces noise transmission, ideal for commercial and residential buildings in noisy environments

· Superior Weather Resistance: Pre-painted aluminum surfaces with PVDF coating resist UV radiation, corrosion, and atmospheric pollutants for 15+ years outdoor service life

· Fire Retardancy: PVC core offers inherent self-extinguishing properties (B1 rating), while special formulations can achieve A2 non-combustible rating

· Waterproof & Moisture-proof: Impermeable aluminum surfaces and closed-cell PVC core prevent water ingress and mold growth

3.3 Processing & Installation Benefits

· Easy Fabrication: Can be cut, drilled, routed, bent, and formed using standard metalworking tools, reducing processing time by 40-50%

· Simple Installation: Lightweight nature allows for faster installation with fewer workers, decreasing labor costs by 25-30%

· Low Maintenance: Smooth, non-porous surface resists dirt accumulation; occasional cleaning with water and mild detergent maintains appearance

· Aesthetic Versatility: Available in various colors, finishes (matte, glossy, metallic, wood grain, stone texture), and custom patterns to meet diverse design requirements

· Furniture Manufacturing: High-end cabinetry, table tops, and decorative elements requiring durability and aesthetic appeal

5. Production Process

The manufacturing of Aluminum/PVC/Aluminum Sheet involves a precise sequence of steps to ensure consistent quality and performance:

5.1 Raw Material Preparation

Aluminum Coil Selection: High-purity aluminum coils (1100/3003 series) with specified thickness (0.12-0.5mm) are inspected for surface quality and chemical composition

PVC Core Preparation: Rigid PVC foam boards or extruded PVC foam cores are cut to required dimensions, ensuring uniform density and thickness

Coating Materials: PVDF or polyester coating formulations are prepared according to color and performance requirements

5.2 Aluminum Surface Treatment

• Cleaning & Degreasing: Aluminum coils are thoroughly cleaned to remove oils, dust, and contaminants using alkaline solutions and rinsed with deionized water

•       Chemical Pre-treatment: Chromate conversion coating or anodizing creates a micro-porous surface for enhanced coating adhesion and corrosion resistance

•        Drying: Coils are dried in an oven at 80-100°C to remove moisture before coating application

5.3 Coating Application

•     Primer Coating: A thin, uniform layer of corrosion-resistant primer is meticulously applied to both sides of the aluminum coils, serving as a foundational protective barrier that enhances adhesion and provides initial defense against environmental degradation.  

•       Top Coat Application: A high-performance PVDF or polyester top coat is subsequently applied through a precise roller coating process, which guarantees an even and consistent coating thickness, typically maintained within the strict range (of 15 to 25 micrometers, to ensure optimal surface durability and aesthetic quality.  

•       Curing: The coated aluminum coils are then transferred to a high-temperature oven, where they undergo a carefully controlled curing process at (temperatures ranging from 220 to 250 degrees Celsius for a duration of 20 to 30 minutes, facilitating the formation of a robust, cross-linked coating film that delivers long-lasting protection and resilience.

5.4 Lamination Process

• Core Preparation: PVC foam core is treated with adhesive primers to improve bonding with aluminum sheets

• Adhesive Application: Two-component polyurethane adhesive is evenly applied to both sides of the PVC core using a roller system

• Sandwich Assembly: Pre-coated aluminum sheets are laminated to both sides of the PVC core in a continuous production line

• Hot Pressing: The assembly passes through a series of heated rollers (120-150°C) under controlled pressure (0.8-1.2 MPa) to ensure complete adhesion between layers

• Cooling & Trimming: The composite panel is cooled to room temperature and trimmed to standard dimensions using precision cutting equipment

5.5 Quality Control & Finishing

• Pel Strength Testing: Random samples are tested to ensure minimum peel strength of 7 N/mm, verifying layer adhesion

• Dimensional Inspection: Thickness, width, length, and flatness are checked against specifications using automated measuring systems

• Surface Quality Check: Visual inspection for coating defects, color consistency, and surface smoothness

• Protective Film Application: A removable PE film is applied to both surfaces to prevent scratches during transportation and installation

• Packaging & Storage: Panels are stacked on wooden pallets, wrapped with moisture-proof film, and stored in a dry, well-ventilated warehouse before shipment
