CNC Machining
Bakelite was the first plastic made from synthetic components. It is a thermosetting phenol-formaldehyde resin. For UK engineers and product designers, CNC machining Bakelite (Phenolic) is a reliable route from prototype to finished part.
It offers good mechanical strength, electrical insulation and resistance to heat, making it a classic choice for insulating parts. Common examples are electrical sockets, consumer products and kitchen supplies. Our team can advise whether Bakelite (Phenolic) is the right fit for your design, or suggest an alternative.
Parts are CNC milled or turned and available in orange-red or black. Get an instant online quote for Bakelite (Phenolic) CNC parts and have them delivered to your door in the UK. Finish options (as machined) can be confirmed when you order. Every order is checked against your drawing before dispatch.

Values shown are typical supplier figures for Bakelite (Phenolic) and may vary with stock condition. Please confirm critical properties before production.
Bakelite is a rigid thermoset that can be machined accurately, but it is brittle, so it is cut carefully to avoid chipping at edges and corners.
As a rigid thermoset, it holds its shape well, but edges can chip or fray, so sharp corners and very thin sections need care. Achievable tolerances depend on part size, geometry and features, so mark any critical tolerances on a 2D drawing with your upload and they will be reviewed and confirmed in your quote.
Bakelite is usually supplied as machined and deburred.
Typical uses include electrical sockets, insulating parts, consumer products and kitchen supplies.
Both are good electrical insulators. FR4 is a much stronger glass-epoxy laminate with very low moisture uptake, while Bakelite is a rigid phenolic thermoset often used for insulating parts and fixtures. Bakelite has poor resistance to oils.
The typical lead time shown for Bakelite is 10 business days from an approved order. Quantity, finishing and any heat treatment can affect this, and your quote confirms the date before you order.
