Harbin Rainbow Technology Launches New Full Mask One Die Two Stroke Nut Making Machine for High Efficiency Fastener Production
Date: June 3, 2026
Harbin Rainbow Technology, a leading fastener equipment manufacturer with over 20 years of specialized experience, is proud to announce the official launch of its highly anticipated new generation full mask one die two stroke nut making machine. This innovative machine is engineered to address the growing global demand for high-quality, high-efficiency fastener production solutions, particularly for the automotive, construction, furniture and electronics industries.
The new LDH-M12-1D2B nut cold heading machine features our exclusive patented fully enclosed protective cover design, which delivers four core advantages over traditional open-type models: it reduces working noise below 85dB to meet EU and US environmental standards, significantly improves workplace safety, prevents oil splashing to maintain a clean production environment, and extends the service life of precision parts by 30% by isolating dust and contaminants.
With a maximum production speed of 200 pieces per minute, this machine is 30% more efficient than conventional models, greatly increasing daily output and reducing labor costs for manufacturers. It is capable of producing a wide range of standard and non-standard nuts within the M3-M12 specification range, including hex nuts, flange nuts, lock nuts, square nuts, weld nuts and coupling nuts. We also offer custom mold design and manufacturing services for special-shaped nuts according to customer drawings or samples.
Built with a heavy-duty cast iron body that undergoes strict aging treatment to eliminate internal stress, this 1 die 2 blow nut former ensures exceptional stability even during 24-hour continuous operation. All core components are precision-machined using advanced CNC equipment, guaranteeing consistent thread precision that meets international ISO 6H standards and a product qualification rate of over 99.8%.
"Our new nut making machine is the culmination of years of intensive R&D and valuable customer feedback," said Mr. Wang, Chief Engineer of Harbin Rainbow Technology. "We have optimized every aspect of the machine's design to enhance performance, reliability and ease of use. Whether you are a small start-up looking to establish your first production line or a large-scale manufacturer planning to expand capacity, this machine offers the perfect balance of performance and affordability."
In addition to its outstanding performance, the machine comes with our comprehensive one-stop service guarantee:
- Strict 72-hour continuous load test run before delivery
- Detailed English operation manuals and step-by-step installation videos
- 24/7 online technical support via WhatsApp, WeChat and email
- 12-month global warranty for the whole machine and 24-month warranty for core components
- On-site installation, debugging and operator training services available worldwide
Most importantly, this nut making machine can be perfectly matched with our automatic multi spindle nut tapping machine to form a complete fully automatic nut production line, providing customers with a seamless turnkey solution from raw material to finished product.
