What Is Cold Forming?
Modern cold forming is a technique used for rapidly forming metal parts such as screws, bolts and many other fasteners. Cold forming, also referred to as cold heading, uses a heavy strike against a cold metal slug to shape it into its desired form. The force of the strike exceeds the metal’s yield strength, causing the metal to flow into the desired shape inside the carbide die.

Material
Gradient alloys use local decarburization to move the cobalt down from the sequence of A to B to C. Thus, the hardest point is at A, followed by B, and the softest point is at C because B and C are both softer than A.
To protect the alloy from getting damaged easily, there is a particular buffer in the process. The mold can disperse part of the force to improve the overall service life of the dies and save customers money.
what is gradient alloy ?
The higher the hardness of the traditional tungsten steel, the worse its toughness, which easily causes damage! While, the lower the hardness, the less wear resistance, and the service life fail to meet standards! Gradient alloys solve the contradiction of the performance of traditional tungsten steel! It has both high toughness and high hardness! It makes the mold resistant to impact and wear! It makes up for the defects of excessive design loading of forging engineering! (The service life extends by 3-6 times)

Carbide Grades for Your Dies
JunGu can make your dies to any carbide grade you specify, however, if you would like a recommendation our expert team will be more than happy to advise you on which grade will be best suited for your operations. For example, one grade will yield more stainless steel parts while others will be more efficient when forming copper. JunGu can analyses how your dies wear out and refer to years of experience to recommend the correct tungsten carbide for you. Furthermore, we will work with you to analyze and perfect your dies performance through feedback and testing.Â
