Product Description
VA80 / ST7 Nut Forming Dies , Carbide Die Cutting Mould Robust Construction
High wear resistance

Cemented carbide drawing die, After the unique advanced technology processing of raw materials, 
it can work in the higher than the temperature of the human body maintain long-term pull pull out
 the wire size is not easy to change,
In the process of drawing of metal wire, steel and nonferrous metal adhesive of drawing die is small, 
so as to make the cemented carbide drawing die with high durability, thus improve the metal surface
is bright and clean degree,
Heat conduction performance of high corrosion resistance
Cemented carbide drawing die, on the wire drawing process, the heat generated by cemented 
carbide die conduction, lower friction coefficient, in the wet drawing lubrication, the cooling lubricant
with good corrosion resistance, wet lubrication drawing in acid solution, is more effective!


Available for most wire drawing operations.
Offered in a wide range of diameters.
For use in wet and dry drawing applications.
For use in pressure and non-pressure applications.
Typical application areas

Copper wire
Aluminum wire
Tungsten wire
Molybdenum wire Stainless steel wire
Coated steel wire
Special alloy and high performance alloy wire
Precious metal wire
Various other ferrous and non-ferrous metal wire types

Production note
1. Select the tungsten steel materials and specifications size to make the screws or nuts mold correctly.
2.According to the difference of the forming difficulty,size,length of screws and nuts,rational design of the mold structure,multi-station and nut mold should be allocated on a reasonable basis the upsetting deformation and the number of molding.
3.The mold fine craftsmanship,accurate size,bore diameter to match the finish mirror requirements.
4.Interference voltage distribution margin,select the appropriate alloy taper size.
5.Shell steel sleeve must be rigid and good heated,and the hardness range should be between 42°c-48 °c after the vacuum heat treatment.
6.Keep the mold bore and the wire surface cleaning and smoothing, cold drawn wire must be nailed after ball annealing treatment.
7.We use diamond grinding wheel to mill the cycle and the end of tungsten.
8.The technicians adjusting the master must have good technical level.
Common questions in using screw and nut mold

1.Mold and structural design experience with the master, not calculated the number of cold heading,analyzing the force of the mold deformation than the unreasonable distribution.
2.The cleanliness of the mold, the inner hole finish is not enough.
3.The rigidity of shell sleeve material, the heat resistance,and the heat treatment hardness are unreasonable.
4.In order to save the cost of production, they selected poor quality tungsten carbide steel and wire rod, alloy specifications and steal material nailing serious wheels unreasonable.
5.They collider in unsuitable way, without replacing lubricants and checking machine long-term.
