Nut Bolt Washer Manufacturing Machine

We are Wenzhou Hunan Machinery. Since 2001, we have specialized in cold heading machinery with over 26 years of engineering and manufacturing experience. This Nut Bolt Washer Manufacturing Machine is a highly integrated forming system designed for unified production of nuts, bolts, and washers on a single platform.
It provides a flexible and efficient solution for manufacturers seeking multi-product capability, reduced production lines, and higher equipment utilization.

This Nut Bolt Washer Manufacturing Machine adopts a modular structural design, allowing each forming unit to be independently removed, replaced, or upgraded according to production requirements.
The die spacing is 140 mm, providing sufficient forming space for process optimization and multi-stage forming stability. The knockout length reaches up to 105 mm, ensuring stable and reliable ejection performance across different product types.
The slide stroke is available in 180 mm and 300 mm configurations, with optional extended stroke designs available for special fastener applications.
Key mechanical components are manufactured using hot isostatic pressing (HIP) alloy materials and nano-composite surface coating technology, significantly improving wear resistance and service life under continuous heavy-load operation.

This machine delivers a maximum forming force of 360 tons, ensuring stable deformation performance across nut, bolt, and washer production processes.

The main motor power is 200 HP, supporting continuous high-load industrial operation. Production speed reaches up to 60 parts per minute, providing a balance between output efficiency and forming stability across multiple product types.

A 3 HP intelligent lubrication system combined with a 2000 L oil reservoir ensures continuous and stable lubrication supply under heavy-duty conditions. The smart zone lubrication network automatically adjusts oil flow according to real-time load conditions at each station, reducing wear and improving overall operating efficiency.

We operate our own dedicated R&D center, with core technical shareholders directly involved in product development and optimization.
We support OEM customization and can design machines based on customer drawings, samples, or production requirements. The minimum order quantity is one unit.
Each Nut Bolt Washer Manufacturing Machine undergoes a 48-hour no-load test run before shipment to ensure mechanical stability, system reliability, and consistent performance.
