Copper Alloy: Brass, bronze, beryllium copper, pure copper
Titanium Alloy: TC4, TA2, GR5
Engineering Plastics: POM, PEEK, Nylon, ABS, Polycarbonate
Material recommendations based on application: corrosion resistance, high strength, lightweight, conductivity, high temperature resistance.
Multiple CNC Processes
We offer a complete range of CNC processes:
● CNC Turning: Conventional and Swiss-type – ideal for shafts, discs, bushings
● CNC Milling: 3-axis, 4-axis, 3+2-axis, 5-axis – suitable for complex surfaces and custom shapes
● Mill-Turn Composite Machining: Complete turning, milling, drilling, tapping, boring in one setup
● Swiss-Type Machining: Ideal for long slender shafts and high-volume small precision parts
● Wire EDM: For hard materials, custom holes, stamping die components
● EDM: For deep cavities, narrow slots, complex precision shapes
Flexible Production Volumes
Support all order volumes:
● Sample prototyping: a few to dozens of pieces
● Small-batch validation: hundreds of pieces
● High-volume production: tens of thousands to millions of pieces
Fast turnaround for sample orders. Flexible scheduling for production orders. Support batch release on demand.
