Bakelite, the original synthetic plastic, remains a cornerstone material in high-performance engineering. Known for its exceptional thermal, electrical, and mechanical properties, it is a phenolic resin that is precisely machined to create robust and reliable components. CNC machining transforms this versatile thermoset into complex, tight-tolerance parts that are essential in demanding electrical, automotive, and industrial applications. When your project requires a material that combines classic durability with modern precision, CNC-machined Bakelite delivers unparalleled performance.
KEY BENEFITS
CNC machining unlocks the full potential of Bakelite, offering a unique set of advantages that make it superior to metals and other plastics in specific applications.
| Benefit | Description |
|---|---|
