Tong Z | From Design to Final Forming
CNC Turning Machine
TONG Z uses a CAD/CAM 2.5D digital machining system. From drawing to machining, all steps are handled in-house to ensure stable processes and consistent quality. We apply this to EDM electrodes, mold case , thread die case , punch case, and toolings.
CNC Milling Machine
TONG Z uses a CAD/CAM 4.5-Axis simulation system for full digital integration from 3D design to machining. Targeting first and second punch shaps, serration, taptite screw, automobile screw, barrel nut and screw, and EDM engraving electrodes.
Grinding
TONG Z uses a human-machine grinding system for internal and external grinding.Computer controls size, experts monitor to ensure accuracy and quality. Ideal for parts needing high roundness and concentricity, like Carbide insert , punch case , die case.
EDM / Self-Made Copper Electrodes
TONG Z has 30+ years of EDM experience and makes its own CNC-milled copper electrodes. We handle precise curves, small radii, and complex shapes with stable machining, solving process and size issues effectively.
Wire Cutting × Taptite screw mold
TONG Z was an industry pioneer using CAD/CAM and wire EDM for taptite thread molds.We have 20+ years of key expertise in this field. Focused on Hex punche, Six segment, taptite screw, TORX, 912, and custom fixtures.
Polishing × Quality
With 30+ years of mold-making experience, TONG Z uses fluid polishing, sandblasting, and expert hand-finishing to boost inner brightness, reduce defects, and extend mold life.
