Custom CNC Machined Phenolic Parts

We specialize in CNC machining of laboratory-grade Fundermax phenolic resin panels, engineered for strength, durability, and dimensional stability. These composite panels are created by curing resin-impregnated kraft layers under high heat and pressure, producing dense, flat sheets with excellent screw-holding strength, dielectric properties, flame resistance, and low moisture absorption.

Panels remain flat under heavy loads and can withstand hundreds of pounds of pressure from weighted materials.

Capabilities

Precision cutouts, grooves/notches, beveled or radiused edges
Ferrule inserts and countersinks for recessed fasteners
Close-tolerance machining on 3-, 4-, and 5-axis mills, lathes, and routers

Industry Applications

Semiconductor & Electronics: Circuit board holders, terminal boards, and other electrical components (high dielectric strength).
Defense: Components meeting stringent Mil-Spec requirements for aerospace and marine environments.
Medical: Devices and diagnostic equipment (chemical resistance and low moisture absorption).
Aerospace: Parts requiring high impact strength and dimensional stability.

Advantages

Close tolerances, excellent machinability, non-warping flatness
Very low coefficient of thermal expansion; very low moisture absorption
Flame retardant with strong dielectric performance
Often lower cost than alternative engineered materials

Best Used In:

Robotics & automation workstations
Laser & microscope tables
Pneumatics, cleanroom, and ESD environments
Computer monitoring stations & classroom applications

Availability

Custom parts are made-to-order with no minimum quantity. Standard panel thicknesses: 1/4",1/2", 3/4", 1" (6, 13, 19, 25 mm).
