BLANKS FOR VARIOUS PURPOSES

Blanks for Die & Mold

Blanks for Die & Mold

We provide stable and high-performance blanks for die & mold.

The Die & Mold demand increases with the expansion of the new technological products such as smartphones or tablets.
On the other hand, the performance enhancement of the Die & Mold Industry is pursued with miniaturization and the densification of molding materials.
We have many customers who utilize our carbide materials for die & mold including AF312 which shows stability and high efficiency.

Grade Properties

We have a lineup of grades that match the application of the mold.
For details, please refer to the technical information.

Specifications of Grade for Special Type

Application / Grade Recommendations

Ultra micro grain

  • AF312

This is the ultra-micro-grain grade with WC 0.3 ㎛.
AF312 grade has the extremely high transverse rupture strength (TRS) and hardness which deliver a long tool life for precision dies & molds.

Fine grain

  • AF810
  • AF813

Recommended grades for punch / die material. They are a balanced grade of hardness and transverse rupture strength (TRS).

General grades for wear resistant tools

  • AV106
  • AV207
  • AV210
  • AV212
  • AV215
  • AV320
  • AV325

The above shows general carbide grades for wear resistant tools.Grades listed in order of highest abrasion resistance: AV106, AV207, AV210, AV212, and AV215.
Please choose the most suitable grade depending on your requirements.

Impact resistance

  • AG408
  • AG410
  • AG411
  • AG416

Material for dies that apply a large impact force such as cold forging. Please select the material based on the table below.
