Diamond Dies Made by High Quality Diamonds
Generally speaking, there are mainly four kinds of diamond dies in the market, say polycrystalline diamond (PCD) dies, natural diamond (ND) dies, synthetic single crystal diamond (SSCD) dies and nano diamond dies. You can choose one kind of diamond dies according to your production requirements in HG.
Why Diamond Dies Are Good Choice for Your Wires ?
Tungsten carbide wire drawing dies and diamond drawing dies are both widely used in wire drawing. With more abrasive resistant and compact diamond inserts, diamond dies will perform better in improving your production efficiency and enhancing your wires’ quality on surface, roundness, accuracy.
Diamond Dies Made by Different Raw Materials
According to the differences among diamonds, HG makes totally 4 diamond dies as follows.
Polycrystalline diamonds are made by carbon under high temperatures and high pressure. Polycrystalline diamond dies have full ranges of sizes for wires and tubes and the tenacity is good.
Natural diamonds are the hardest material on the earth naturally formed in physical Environment. With Mohs’ hardness 10, natural diamond dies are very abrasive resistant to have a long service time and shiny wire surface.
Just like PCD, synthetic single crystal diamonds are also artificial. Compared with ND, mono diamond dies have better consistency on inner texture to make your wires’ surface smooth.
With a diamond film grows on the inner hole of the tungsten carbide die by chemical vapor deposition, nano diamond dies are abrasive resistant and tough enough to perform well especially in big sizes wires, bars and tubes.
Applications of HG Diamond Dies
How choose HG diamond dies for your wires?
With long service life, polycrystalline diamond dies are usually used to draw medium sizes wires from 0.1mm to 5.0mm and tubes, bars in big sizes.
If your main products are samll size wires from 0.01mm to 1.5mm and there are high requirements on wire surface. Natural diamond dies will be the best choice for you.
As artificial diamonds, synthetic single crystal diamonds have more consistent texture to ensure the life time of diamond dies and smooth wire surface.
With high cost performance, nano diamond dies perform well in bigger sizes wires and tubes drawing. At the same time, the surface of your wires and tubes can be predictable.
What About The Advantages of Diamond Dies?
Compared with tungsten carbide dies, diamond dies have following advantages.
From minimum size 0.01mm to maximum 80.00mm, there is a full range of diamond dies for your wires and tubes.
Diamonds are the hardest materials in the world. That’s why diamond dies are abrasive enough to own a long life time.
Inner structure of diamonds inserts are compact, consistent to ensure the precise wire diameters and roundness.
Wires drawn by diamond dies have always shiny surface, say gold,silver,aluminum,platinum, steel wires and so on.
One Stop Solution for Diamond Dies
Polycrystalline diamond dies, natural diamond dies, synthetic single crystal diamond dies and nano diamond dies have different characteristics in both producing and wire drawing processes.
After many years’ producing and improving , HG have had a good command of their characteristics to make the correct diamond dies you want.
Excellent Performance
Qualified raw materials (diamonds, cases, sintering powder etc) and many years’ of production experience bring excellent performance to HG diamond dies. Both the reasonable inner geometry and long life time of the diamond dies will improve your production capacity greatly.
Technical Support
Besides diamond dies knowledge, if you need some support on dies matching or wire drawing, HG technicians with rich experience are also able to provide support accordingly. If your wire factory need some customized diamond dies with special inner geometry , case shapes, we are able to make them accordingly.
As one of the specialiaed diamond dies manufacturers, diamond dies are only a part of our products and service. Your related demand on wire drawing can also be met .
Some of our customers are new to wire drawing and we supply a serial of products and service to help them finishing wire drawing process sucessfully.
Recutting
To improve the utilization rate of diamond dies, some customers may need to recut the used dies to new diameters. Made by big diamonds, HG diamond dies have enough areas to be recut, so used diamond dies recutting service is also available here.
Generally speaking, some used diamond dies can be recut but some ones had been destroyed severely in wire drwing prosess. We will firstly checked your used dies and then enlarge or repaire them to be proper diameters according to the dies status. In this case, the diamond dies can be used repeatedly and your production cost will be cut down.
Why You Can Choose Our Polycrystalline Diamond Dies?
As an important diamond die and mold, polycrystalline diamond dies have many advantages which make they can be used in almost all wires, say aluminum, steel, gold,silver, platinum and many kinds of alloy wires.
Polycrystalline diamonds have are though enough to bear the drawing press in wire drawing. So polycrystalline diamond dies service time are comparatively longer than other diamond wire dies.
There are several kinds of PCD blanks for your choice to make diamond dies, with or without tungsten carbide rings, with or without metal binder, grain sizes from 1 micron to 50 micron .
Polycrystalline diamonds are comparatively easily processed to many shapes for different shapes of wires, tubes. Besides normal round, hexagon, oval , rectangular, half round and other complex shaped diamond dies are also available.
As a widely used diamond tool and die, polycrystalline diamond dies own wide range of diameters from 0.10mm ~ 27.00 mm and good abrasive resistance to draw all kinds of wires, bars, tubes.
How to Choose Diamond Dies for Wire Drawing ?
There are several kinds of dies made from diamond, which have different characteristics and advantages. If you want to choose choose proper diamonds dies for your wires, tubes, the table below will help.
| Diamond Dies | Diameter Range (inch) | Diameter Range (mm) | Appliable Wires |
| Natural Diamond Dies | 0.00039 ~0.05118 | 0.01~1.30 | Small Sizes of Steel,Copper, Chromium Wires with Good Surface |
| Synthetic Single Crystal Diamond Dies | 0.00039~0.05512 | 0.01~1.40 | Small Sizes of Steel, Nickel Palted Wires with Shiny Surface |
| Polycyrstalline Diamond Dies | 0.00315~1.1417 | 0.08~ 29.00 | Medium Sizes of Copper, Aluminum, Steel,Silver, Alloy Wires |
| Nano Dies | 0.01968~2.16535 | 0.50~55.00 | Big sizes of Copper, Aluminum, Steel Wires,Tubes & Bars |
Differences Between Natural Diamond Dies and Synthetic Single Crystal Diamond Dies
Difference of these 2 dies are mainly from the diamonds. Although having similar characteristics, natural diamonds and synthetic single crystal diamonds are still different on following points.
| Diamonds | Origin | Mohs’ Hardness | Appearance | Inner Structure |
| Natural Diamonds | Natural | 10 | White | Good Consistency |
| Synthetic Single Crystal Diamonds | Artificial | Approximate 10 | Light Yellow | Excellent Consistency |
The service time of diamond dies is much more than that of TC dies and the surface of wires drawn by diamond dies are better. But TC dies price is much cheaper than diamond dies.
By now, we have PCD, SSCD, natural diamond and nano diamond dies.
Different diamond dies are made by different diamonds inside.
Some diamonds are domestic and others are imported. You can also designate one.
Generally speaking, PCD dies are better for cable wires, such as copper, and aluminum wires.
Stainless steel wires usually require good surface. Natural diamond dies and synthetic single-crystal diamond dies are both proper.
Yes, HG own 20 years’ experience in making PCD wire drawing dies, shaving dies and ND, MONO diamond dies.
We have a strict rules to control the quality from raw mateiral to production process and final insepction for diamond dies. Customer feedback is also very important for us to improve the products and service.
Besides diamond dies, our factory also manufacture tungsten carbide dies, nozzles, wire guides, shaving dies and so on.
Sure, samples are available after we communicating clearly about your requirements on the diamod dies.
