As time goes on, there will be a lot of problems when we use the tungsten steel mold. Such as collapse or crush is a common problem. It could easily lead to collapse because of lack of tungsten steel itself high hardness, low toughness, so It is the main point to broken to use tungsten steel so long time or die after dislocation.
We could to change the feature tungsten steel itself, there is no other reason for it? In fact, through our years of Fujipunch processing experience is concerned, there are still many causes of the possibility of tungsten steel collapsing missing! That is processed by the galvanic corrosion of tungsten steel surface!
As we know, tungsten steel is a carbide punch material, so at this stage of processing methods is very little, machining plane, then the choice of surface grinding to machine, inner and outside the hole is chosen external circular grinding or coordinate mill to process, surfaces, or R processing generally is chosen to process the optical grinding, EDM shaped bit is chosen, the selection of the through-hole or contour line cutting processing. The discharge or cut processing is done by the surface high-voltage parts processing corrosion, as a word, in addition to grinding the outside is processed galvanic corrosion.
Whether electric corrosion of tungsten steel have no effect on the surface or not? The result is positive! Because the principle of EDM is to make tungsten steel mold surface is formed in an instant high current, Powder metallurgy mould surface erosion continues, a shape to be machined at the same time corrosion, high-current voltage to the surface of a tungsten steel Article crack, crack roads lead to precisely the mold after constant use, easy to crack expanding, leading to mold the final collapse of missing or smashed.
Therefore, the collapse of the mold problem in addition to the lack of material for their own characteristics, The main problem is actually more processing method, we suggestion that make less use of electrical discharge machining for tungsten steel, preventing the formation of hairline cracks after the collapse of surface corrosion, resulting in lack of mold.
Fujipunch is only use Fujilloy imported from Japan as material, it is processed by Toshiba and YASDA and other nano-precision machining equipment.Through the precision mold punch to service safe and reliable component manufacturing for customers in the automotive industry, contribute to human exquisite life. And to become auto parts mold ultra-carbide punch benchmark brand.
