Details

The Chun Zu CNH series is a 1-die 2-blow cold former, also known as a single die double stroke (SDDS) cold former, with a bushing cutoff. Featuring the CNH-6L model, it is designed for producing simple components with unparalleled precision.

Engineered with a range of advanced features, including a bushing cutoff mechanism, synchronous PKO mechanism, pneumatic transfer, and a new knock-out mechanism, the CNH-6L is the perfect solution for manufacturers in the automotive and construction industries who require high accuracy and efficiency in their cold forming processes.

The CNH-6L’s bushing cutoff mechanism ensures a flatter cutting surface, making it ideal for producing high-precision products where exact dimensions are critical. This feature significantly reduces material waste while enhancing the quality of the finished components.

The synchronous PKO mechanism works in harmony with the rest of the machine, ensuring precise timing and coordination during the forming process, which is essential for maintaining consistent product quality.

The pneumatic transfer system in the CNH-6L provides smooth and reliable movement of components through the forming stages, further contributing to the machine’s overall efficiency and precision.

Additionally, the new design knock-out mechanism enhances the ease and reliability of removing finished products from the machine, reducing downtime and increasing production throughput.

Whether you're manufacturing critical automotive components that demand high precision and performance or producing fasteners for the construction industry that must meet stringent standards, the CNH-6L offers the advanced technology and reliability you need.

This machine's combination of cutting-edge features and high-precision capabilities makes it an invaluable asset for any manufacturer looking to optimize their cold forming operations.

Choose Chun Zu's CNH-6L Cold Header for your high-precision forming needs and experience the advanced technology, efficiency, and quality that have made Chun Zu a trusted leader in the cold forming industry for over four decades.
