Why Bakelite Fixture Bases?
Bakelite Fixture Bases use phenolic resin laminate, a material that combines electrical insulation, thermal resistance and dimensional stability at a fraction of the cost of high-performance plastics.
| Property | Bakelite (phenolic) | 6061-T6 aluminium | PEEK |
| Density (g / cm³) | 1.35 | 2.70 | 1.30 |
| Continuous service temp. (°C) | 120 | 100 | 250 |
| Surface resistivity (Ω) | ≥ 10¹² | 10⁻⁵ | ≥ 10¹³ |
| Compressive strength (MPa) | 180 – 250 | 276 | ≈ 110 |
| Relative cost | ★ | ★★ | ★★★★★ |
Key engineering take-aways
- Electrical safety: ideal near live conductors or E-stop circuits
- Stiff yet lightweight: half the weight of aluminium at comparable rigidity
- Cost-effective: roughly 20 % of PEEK’s material cost for the same footprint
Typical Engineering Applications
- Semiconductor assembly plates requiring vacuum ports and ESD safety
- Automated test equipment (ATE) jig bases with sensor mounting holes
- Power-electronics burn-in trays operating up to 120 °C
- Lightweight manual fixtures in medical-device assembly cells
Design Guidelines for Engineers
- Threaded features: Use brass or stainless inserts; avoid direct tapping above M6.
- Wall thickness & hole spacing: Wall ≥ 2 × hole diameter; edge distance ≥ 3 × hole diameter.
- Surface finish: As-milled Ra ≈ 3.2 µm; polishing or clear-coat available when aesthetics matter.
- Flatness call-outs: Specify explicit flatness (e.g., 0.05 mm/300 mm). Excessive tightness escalates cost.
- Moisture protection: Vacuum-seal or foil-bag packaging prevents dimensional drift during transit.
