Import Hardware Spring Production Equipment — Buy in wholesale FOB from Supplier in United States

The camless spring production line offered by Shenzhen Unionspring Technology Co., Ltd. is a dedicated hardware spring manufacturing machine. It is available in two models, US‑236 and US‑480, each equipped with ten axes for precise movement. Wire diameter handling ranges from 0.3‑2.5 mm on the US‑236 and 1.5‑5.0 mm on the US‑480, with two or three wire‑wheel sets respectively. The machines measure 1200 × 1250 × 1760 mm (US‑236) or 2200 × 2000 × 1850 mm (US‑480) and weigh 980 kg or 2500 kg respectively. Each unit incorporates independent servo‑motor groups that replace traditional cam mechanisms, delivering over 50 % faster adjustment speed and smoother positioning. The camless, rockless arm design reduces mechanical wear and improves long‑term stability, a benefit recognised across spring‑making facilities. Intelligent modules provide automatic detection, alarm functions and bilingual Chinese‑English displays for easy operation. The combination of high‑speed axes and precise control makes the equipment suitable for high‑volume production environments.

The machine’s servo‑driven architecture aligns with typical industry standards for spring coil winding, where power ratings between 0.75 kW and 4.4 kW per axis are common. Typical control interfaces in this segment include PLC‑based panels with touchscreen displays, allowing operators to set wire tension, pitch and coil count with fine granularity. Standard safety features such as emergency stop circuits and overload protection are incorporated, matching the expectations of ISO‑13849‑1 compliant facilities. Compared with conventional cam‑driven lines, the camless design reduces setup time and enables more complex spring geometries, a capability valued by automotive and aerospace component makers.

Potential buyers include manufacturers of automotive suspension springs, appliance valve springs and precision instrument spring assemblies. The equipment is positioned for factories that require rapid change‑over between spring types and a high degree of dimensional repeatability. Shenzhen Unionspring Technology Co., Ltd. states it can provide after‑sales engineering support and arrange on‑site visits to its Shenzhen factory. Trade terms, incoterms and payment conditions are not disclosed in the listing and should be confirmed directly with the supplier before placing an order.
