Acrylic (PMMA) CNC Machining Service
Machined acrylic is a rigid, translucent thermoplastic that offers UV stability.
What is Acrylic or PMMA?
Acrylic, also known as polymethyl methacrylate (PMMA), is a versatile plastic material widely used in CNC machining for its remarkable properties. Acrylic's optical clarity, light transmission, and UV resistance make it a popular choice for a wide range of applications, from signage and display products to lenses and lighting fixtures.
With its exceptional combination of optical clarity, machinability, and versatility, acrylic is an excellent choice for CNC machining applications that require precision and aesthetics.
