Product Q&A
Q:Can FR4 tubes be machined with standard tools?
A:
Yes. They can be cut, drilled, milled, turned, and tapped using carbide-tipped or diamond-coated tools. Dust extraction is recommended during machining.
Q:What are the common applications for FR4 tubes?
A:
Typical uses include insulating bushings, PCB test fixture supports, coil bobbins, motor insulation sleeves, robotic arms, and aerospace/rail transit components.
Q:How do I select the right wall thickness and diameter?
A:
Selection depends on mechanical load, voltage rating, and space constraints. Thicker walls offer higher dielectric strength, while thinner walls save weight and cost.
Q:Are FR4 tubes suitable for outdoor or humid environments?
A:
Yes, due to low moisture absorption (<0.2%). However, for prolonged UV exposure, protective coatings or GPO-3 are recommended to prevent UV degradation.
Q:Do you offer samples before bulk ordering?
A:
Absolutely. We provide free or low-cost samples (shipping may apply) so you can evaluate material quality, color, and machinability before placing a full order.
