The transition to composite materials like carbon fiber and fiberglass requires molds with exceptional dimensional stability, superior surface finish, and the ability to withstand autoclave cycles. CNC machining meets these challenges headon. Using advanced 3, 4, and 5axis CNC systems, manufacturers can directly mill these complex tools from solid blocks of highgrade aluminum or steel. This subtractive process guarantees unparalleled accuracy, ensuring that every contour, vent, and mounting feature is machined to exact specifications. This precision directly translates to the final composite part, minimizing defects like porosity and ensuring perfect fit and function.

Beyond common aluminum molds, CNC machining is also pivotal for creating master models and plugs used in subsequent molding processes. The ability to machine a wide range of materials, including temperatureresistant tooling boards and invar, provides our clients with the flexibility to choose the optimal solution for their production volume and performance requirements. A highquality CNCmachined mold delivers a flawless surface finish off the machine, drastically reducing the time and cost associated with manual polishing and finishing. This efficiency accelerates timetomarket for our clients' products.
