Nut Former

We are Wenzhou Hunan Machinery. Since 2001, we have specialized in cold heading machines with a focus on durability, precision, and long-term production stability. This Nut Former is designed for high-volume production of hex nuts and flange nuts. It is engineered to ensure stable hole concentricity and consistent dimensional accuracy during continuous operation.

In nut forming, internal hole alignment and concentricity are critical quality factors. Any deviation in die alignment may lead to eccentric holes or unstable threading performance.

This Nut Former adopts a reinforced die guiding system combined with a high-rigidity slide structure to improve alignment stability during forming operations. The die spacing is 80 mm, optimized to maintain consistent forming geometry and reduce deflection under high load.

The knockout length is adjustable from 52 to 82 mm, providing stable ejection performance for deep-hole nuts and thick-wall structures while reducing internal stress during discharge.

This machine delivers a maximum forming force of 185 tons, ensuring reliable deformation control for medium to large nut specifications and higher-strength materials.

The main motor power is 60 HP. Production speed ranges from 60 to 100 parts per minute depending on material and product geometry. Slide stroke is available in 180 mm and 210 mm configurations to accommodate different forming requirements.

A 2 HP intelligent lubrication system with a 1200 L oil reservoir ensures continuous lubrication supply under heavy-load conditions. The system incorporates temperature-responsive oil flow control to maintain stable operating conditions and reduce wear during long production cycles.

This Nut Former is designed for continuous, stable industrial production with consistent dimensional accuracy.

We operate our own in-house R&D team, with direct involvement from technical shareholders in product development and process optimization.

We support OEM customization with a minimum order quantity of one unit. Customized machine configurations can be developed based on drawings, samples, or production requirements.

Each Nut Former undergoes a 48-hour no-load test run before shipment to verify mechanical stability and operational reliability. All machines are delivered in production-ready condition.
