Overview:
Bakelite, a thermosetting plastic, is widely used in industrial fixture boards due to its high mechanical strength, excellent electrical insulation, heat resistance, and dimensional stability.
Main Application Scenarios:
Electronic/Electrical Assembly Fixtures: For fixing and supporting PCBs, sockets, or electronic components, ensuring safety during testing and soldering.
Machining Positioning Boards: Used to securely hold precision workpieces, improving machining accuracy.
Welding/Assembly Fixtures: Provide stable support, withstand high temperatures, and maintain shape.
Experiment/Test Platforms: For electrical and electronic experiments, ensuring insulation safety.
Advantages:
Excellent electrical insulation for safe operation
High heat and chemical resistance
High strength to withstand repeated pressure and impact
Dimensional stability suitable for long-term use
Can be molded into various sizes and complex shapes
When selecting Bakelite boards, consider purpose, mechanical strength, heat resistance, machinability, and cost:
| Board Type | Thickness (mm) | Temperature (°C) | Machinability | Typical Applications | Notes |
|---|---|---|---|---|---|
| Standard Bakelite | 3 – 15 | 120 – 150 | Easy to cut, drill, mill | Electronic/electrical assembly, light machinery positioning boards | Low cost, suitable for general industrial use |
| High-Density Bakelite | 5 – 20 | 120 – 150 | Requires careful tooling | Heavy-duty workpiece positioning, fixture plates | Higher load and impact resistance |
| Glass-Fiber Reinforced Bakelite | 3 – 15 | 150 – 180 | Low-speed cutting recommended | High-temperature welding fixtures, high-strength machining boards | High strength and heat resistance |
| Molded Bakelite | 3 – 12 | 120 – 150 | Can be formed into complex shapes | Special-shaped fixture boards, electrical test platforms | Customizable shapes for complex workpieces |
| Low-Dielectric-Loss Bakelite | 3 – 12 | 120 – 150 | Easy to machine | High-frequency electrical test platforms, precision electronic fixtures | Suitable for high-frequency signal applications |
Heavy load or high mechanical impact → Choose high-density or glass-fiber reinforced type.
High-temperature operation or welding environment → Choose heat-resistant or glass-fiber reinforced type.
Precision electrical testing → Choose low-dielectric-loss or standard insulating type.
Complex workpiece fixing → Choose molded type, customizable in shape.
