PC Board and Acrylic Board Precision Machining in Commercial Display: A Complete Process from Design to Implementation
Commercial display is a critical component of brand image building, with increasingly demanding requirements for the materials, craftsmanship, and finish quality of display fixtures. PC board (polycarbonate) is renowned for its ultra-high transparency and impact resistance, while acrylic board (PMMA) has become the preferred material for display fixtures thanks to its excellent workability and rich color options. Dongguan Chaorong Electronics Co., Ltd. has specialized in PC and acrylic board precision machining for 15 years, providing one-stop custom services for brand owners, advertising agencies, and retail terminals. This article provides a detailed analysis from three perspectives: material properties, processing techniques, and application cases.
PC Board vs. Acrylic Board Performance Comparison
PC board and acrylic board are both transparent engineering plastics, but their performance characteristics differ:
| Performance Parameter | PC Board | Acrylic Board | Comparative Analysis |
|---|---|---|---|
| Light Transmittance | 88-90% | 92-93% | Acrylic has slightly higher transmittance |
| Impact Strength | 600-850J/m | 15-20J/m | PC is 40x stronger than acrylic |
| Tensile Strength | 60-75MPa | 55-75MPa | Comparable |
| Heat Deflection Temperature | 130-140°C | 95-105°C | PC has higher temperature resistance |
| Density | 1.20g/cm³ | 1.18-1.20g/cm³ | Comparable |
| Workability | Good | Excellent | Acrylic is easier to machine |
| Cost | Higher | Lower | Acrylic is more cost-effective |
| Weather Resistance | Good | Excellent | Acrylic has better UV resistance |
Material Selection Guide:
- Impact resistance and protection required: Choose PC board — such as protective face shields and safety barriers
- High transmittance and rich colors required: Choose acrylic board — such as display stands, light boxes, and signage
- Comprehensive performance required: PC + acrylic combination to leverage the advantages of both materials
Typical Commercial Display Application Scenarios
1. Product Display Stands
Application Scenario: Shopping mall counters, trade show displays, new product launch events
Material Selection: Transparent acrylic as primary material, with colored acrylic accents
Processing Techniques: CNC carving, polishing, bonding, silk screening
Design Considerations:
- Thickness selection: 3-5mm for small product display, 8-15mm for large product display
- Structural design: Multiple options available including layered, rotating, and wall-mounted styles
- Brand elements: Silk-screen printed logos, laser engraving, UV printing patterns
2. Commercial Signage and Wayfinding Systems
Application Scenario: Corporate reception logo walls, mall directional signage, store signage
Material Selection: Acrylic panel + LED light source
Processing Techniques: Laser cutting, engraving, polishing, assembly
Typical Products:
- Backlit letters: Acrylic panel + metal frame + LED module
- Directional signs: Acrylic board with UV printed patterns, wall-mounted or freestanding installation
- Reception logo wall: Multi-layer acrylic stacking for 3D effect
3. Electronic Product Display Protective Covers
Application Scenario: Mobile phone store displays, digital product showcases, jewelry displays
Material Selection: PC board (impact resistance) or acrylic (transparency)
Functional Features:
- High transparency: Faithfully reproduces product appearance
- Dust and theft protection: Sealed structure with lock provisions
- Customizable: Custom shapes and hole positions based on product dimensions
4. Industrial Protection and Equipment Enclosures
Application Scenario: Machinery equipment protective covers, instrument windows, safety barriers
Material Selection: PC board (impact resistance and temperature resistance)
Technical Requirements:
- Thickness: Calculated based on impact energy, generally 3-10mm
- Processing: Drilling, bending, assembly
- Certification: Safety protection applications require relevant testing certification
PC/Acrylic Board Precision Machining Techniques
Cutting and Blank Preparation
- Laser Cutting: Preferred for acrylic; clean cut edges without secondary polishing required; PC board laser cutting may cause yellowing, requiring careful power control
- CNC Carving: High precision (±0.1mm), suitable for complex shapes and batch processing
- Panel Saw: Large-size flat sheet cutting, high efficiency, suitable for initial blank preparation
Forming Processing
- Thermoforming: Acrylic softening temperature 150-160°C, PC softening temperature 150-160°C; requires specialized thermoforming machine
- Vacuum Forming: Suitable for batch production of complex curved shapes
- Cold Bending: PC board can be cold bent; minimum bending radius is 150 times the board thickness
Surface Treatment
- Polishing: Flame polishing (acrylic), buffing, diamond polishing
- Silk Screening: Printed patterns, text, and logos
- UV Printing: Full-color printing, no plate-making required, suitable for small batches
- Sandblasting: Frosted effect for enhanced texture
Bonding and Assembly
- Acrylic Bonding: Chloroform (trichloromethane) or dedicated acrylic adhesive; transparent joint
- PC Board Bonding: Dedicated PC adhesive or solvent-based adhesive
- Mixed Bonding: Bonding PC to acrylic requires UV adhesive or silicone
Complete Process from Design to Implementation
Step 1: Requirements Communication
Customer provides product display dimensions, quantity, and display scenario renderings or sketches
Step 2: Design and Planning
Engineers design the display stand structure based on requirements, outputting CAD drawings and 3D renderings for confirmation
Step 3: Material Selection
Material type, thickness, and color selected according to design requirements; samples provided for confirmation
Step 4: Processing and Manufacturing
CNC carving/laser cutting → polishing treatment → bonding and assembly → silk-screen logo printing → quality inspection
Step 5: Packaging and Shipping
Bubble wrap + cardboard packaging to prevent shipping damage
Step 6: Installation Guidance
Installation drawings and video guidance provided; on-site installation available if necessary
