The CVD coating stranding dies were prepared using the HFCVD method, with a nanocomposite diamond coating on the inner bore working surface.
The composite coating has good nano-surface morphology, and the grain size of the diamond on the surface is about 20-50 nm. The die can be widely used in the wire and cable industry for stranding and tightening aluminum (copper) conductors.
In different stranding equipment and stranding speeds, nano-diamond composite CVD coating stranding dies a production length of 1000 km or more. Ordinary tungsten carbide die production length of about 25-30KM, there will be hairy, sticky aluminum (copper), hole size phenomenon until soon scrapped;
The friction coefficient of nano-diamond CVD coating stranding dies is small. Can improve the surface quality and finish of the tightly pressed stranded wire, the generation of surface burrs is greatly reduced.
It can significantly reduce the discharge of the tip of the punctured insulation or medium and high voltage cables caused by conductor burrs, thereby significantly improving the withstand voltage test pass rate and greatly reducing the partial discharge charge.
The effect is particularly good for soft aluminum wire (aluminum alloy wire) appearance shaping. It can successfully ensure that special overhead conductors are through the high-voltage corona test.

FAQ
For sample orders, we charge a nominal sample fee plus shipping costs.
The sample cost can be credited toward future cooperation as a form of discount.
Please note that any additional charges arising from local customs or government regulations are not covered by our company.
Our products are manufactured to order. The standard production cycle ranges from 7 to 20 working days, depending on the order quantity.
Throughout the entire process, we strictly follow ISO 9001 quality management standards to ensure consistent quality and reliability.
We offer several shipping options and will recommend the most suitable method based on your order volume, urgency, and destination.
Alternatively, you may choose to use your preferred shipping method.
1. International Express
We typically use DHL, FedEx, UPS, and other major express services.
This method offers fast delivery, door-to-door pickup, real-time tracking, and a high level of security during transportation.
It is suitable for small batches and sample orders, with delivery usually taking 5 to 7 days to most destinations.
2. Sea Freight
Sea freight is ideal for large-volume and non-urgent shipments, such as bulk orders of wire drawing dies.
It provides lower transportation costs, though the transit time is longer — typically 30 to 45 days from China to Europe or the United States.
3. Air Freight
Air freight is ideal for small to medium-volume shipments, offering a good balance between cost and delivery time.
Typically, air freight takes 5 to 10 days to reach most destinations worldwide.
