In modern metal finishing operations, achieving consistent surface quality depends heavily on the stability and accuracy of polishing jigs. This is especially true for precision components such as door handles and decorative hardware, where even minor deviations can affect appearance and performance. Phenolic board (Bakelite) has proven to be a highly reliable material for polishing jigs used in automated and semi-automated polishing equipment.

Heat Resistance That Supports Continuous Operation

Polishing processes generate substantial heat due to friction between tools and metal surfaces. Conventional jig materials may soften or deform under these conditions, leading to alignment issues. Phenolic board offers excellent thermal resistance, capable of tolerating short-term temperatures exceeding 200°C. This allows jigs to remain dimensionally stable during long production cycles, ensuring consistent positioning of workpieces throughout operation.

Structural Stability for Precision Polishing

Precision polishing requires jigs that can securely hold parts without flexing. Phenolic board provides high rigidity and excellent dimensional stability, making it ideal for small and medium-sized metal components. Its ability to maintain tight tolerances helps prevent workpiece movement, resulting in more uniform finishes, fewer defects, and improved overall process efficiency.

Long Service Life in Demanding Environments

Polishing jigs are continuously exposed to abrasive compounds, metal debris, and chemical polishing agents. Phenolic resin is naturally resistant to wear and chemical attack, allowing jigs to perform reliably over extended periods. Compared with softer materials, phenolic board resists deformation under repeated clamping and tool contact, significantly reducing downtime and replacement frequency.

Designed for Automation and Customization

Automated polishing systems require jig materials that can withstand high-speed motion and repetitive mechanical stress. Phenolic board meets these requirements while remaining easy to machine. Its excellent machinability supports custom jig designs tailored to specific equipment layouts and part geometries, from simple cylindrical components to complex hardware shapes.
