The US-20 and US-35 models of Union Spring Technology’s 3D CNC Special-shape Spring Making Machine are precision systems for producing complex springs with multi-axis control. The US-20 handles wire diameters from 0.3 to 2.5 mm and max outside diameters up to 50 mm, while the US-35 extends this to 0.8 - 3.5 mm wire and 80 mm max OD. Both use a Taiwan computer control system and Japanese servo motors for high-speed, high-precision operations, with synchronous movement across camshaft, feed shaft, rotary shaft, and optional take-up accessories.
The machines support carbon steel, stainless steel, and high-tensile alloy wires, with typical industry grades including music wire (ASTM A228), oil-tempered MB (ASTM A229), and stainless steel 302/304 (ASTM A313). The cam section features eight groups of sliders, cams, and camshafts, enabling extrusion, stamping, and forming actions. Wire feeding is computer-controlled with a minimum unit of 0.01 mm, and the rotating mandrel allows multi-directional curling for torsion, tower, and double torsion springs.
These machines are used in automotive, aerospace, electronics, and industrial equipment sectors where tight tolerances and repeatability are critical. Buyers typically source them for OEM manufacturing, prototype development, or high-volume production runs. The US-20 weighs 1000 kg with dimensions of 1600x700x1700 mm, while the US-35 weighs 2000 kg at 1650x1100x1900 mm. Confirm lead times, Incoterms, and packaging options directly with the supplier, as these vary by configuration.

Before ordering, verify the machine’s compatibility with your required wire materials and spring types. Request samples or test runs to confirm the US-20 or US-35 can meet your tolerance and production volume needs. Check if the supplier provides training or setup support for new buyers.
Confirm logistics details such as Incoterms (e.g., FOB Shenzhen), lead times for machine assembly and shipping, and packaging standards for international transport. Clarify whether the supplier handles export documentation or if you must arrange it independently. Discuss payment terms, such as TT or LC, and any required deposits.
Inspect the machine upon delivery for compliance with the listed specifications, including wire diameter ranges, motor power, and dimensions. Request a factory acceptance test (FAT) or third-party inspection report to verify performance. Ensure all technical documentation, such as operation manuals and wiring diagrams, is included and translated if necessary.
