How to Choose the Right Size and Thickness
Most common thicknesses are 3mm, 5mm, and 6mm. These provide adequate support for PCB drilling operations while being cost-effective. Popular sizes: 100×150mm, 200×250mm.
Medium thickness (8-12mm) offers better rigidity for testing equipment and assembly fixtures. Recommended for applications requiring structural stability.
Thick boards (15mm+) are ideal for high-load machinery components, structural insulation, and applications requiring maximum mechanical strength.
We can cut any dimension from 50mm to 1000mm. Request custom cutting service for non-standard sizes.

Frequently Asked Questions
Both colors offer identical electrical and mechanical properties. Orange bakelite is traditionally used for high-visibility electrical applications, while black bakelite is preferred for its professional appearance and is commonly used in fixtures, jigs, and machinery components where aesthetics matter.
Yes. Black bakelite has excellent dielectric strength suitable for applications up to 20kV depending on thickness and configuration. Always consult with a qualified electrical engineer for specific voltage rating requirements in your application.
For PCB drilling fixtures, 3mm-6mm thickness is most common. 3mm is economical for light-duty use, 5mm offers good balance of rigidity and cost, while 6mm provides maximum support for precision drilling operations. Larger boards may require 8mm+ for added stability.
Absolutely. Phenolic resin boards machine very well with CNC equipment. We recommend carbide-tipped tools for best results and longer tool life. Use moderate speeds (15,000-18,000 RPM) and adequate chip evacuation to prevent resin buildup on cutting edges.
Yes! We offer full custom CNC machining services including drilling, milling, turning, engraving, and complex contour cutting. Simply send us your CAD drawing (DWG, DXF, PDF, or STEP format) and we'll provide a detailed quote within 12 hours.
We accept all common CAD formats including DWG, DXF, PDF, STEP, IGES, and SolidWorks files. You can also send us hand-drawn sketches with dimensions - our engineering team will create a technical drawing for your approval.
Yes. We can provide material certificates, RoHS compliance documentation, technical data sheets (TDS), and physical property test reports upon request. Contact our team for specific certification requirements.
Our standard stock sizes range from 100×100mm up to 300×400mm. For larger custom sheets up to 1000×2000mm or non-standard dimensions, please contact us for availability, pricing, and lead time.
Clean with a soft cloth and mild detergent or isopropyl alcohol. Avoid harsh solvents like acetone or strong acids. Store in a dry environment away from direct sunlight to maintain optimal mechanical and electrical properties.
Bakelite has good resistance to moisture and chemicals, but prolonged UV exposure can cause surface degradation. For outdoor or marine applications, we recommend protective coatings or consider alternative materials like UHMW-PE or marine-grade plastics.
