Advanced CNC Metal Components Manufacturing
Metal Craft provides high-precision CNC metal machining services backed by 50+ years of engineering experience. Equipped with advanced multi-axis CNC Vertical Machining Centers (VMC), high-speed CNC turning lathes, and wire-cut EDM machinery, we manufacture custom machined metal parts adhering to tight sub-micron tolerances for automotive, electrical, aerospace, and industrial OEMs.
Our CNC machining division processes a wide spectrum of metals including Stainless Steel (SS 304, SS 316), Aircraft Grade Aluminum (6061-T6, 7075), Mild Steel, High-Conductivity ETP Copper, Phosphor Bronze, and Brass alloys. From single prototype components to high-volume production batches, our skilled CNC programmers ensure 100% dimensional accuracy and burr-free surface finishes.
