Technological Lineup

01 AS Treatment

After AS Treatment - Before AS Treatment

Unique Surface Treatment Developed by ASAHI TEC
AS Treatment is a special physical treatment to smooth the surface and inner roughness of cast metal regardless of its form. It can also be effectively utilized as a complementary process to improve the hardness and yield strength. Inner roughness of cast metal can now be smoothed in every part as shown in these photos. The main expected effects of AS Treatment are:

  1. Improved engine performance with increased air intake efficiency.
  2. Improved fatigue strength with increased surface hardness.
  3. Improved yield ratio of exterior components (painting, coating, etc.)


02 Large-Size Magnesium Die-Casting (ACTIV-MG)

Large-Size Magnesium Die Cast for Ultimate Weight-Reduction
ACTIV-MG is a development process that combines our original Magnesium Die-Cast technologies with our renowned product development technologies. By using the high ductility material of AM60B, the unified structure of large-size magnesium die cast realizes weight reduction, integrating a series of technologies such as molten metal flow analysis, die structure design, and magnesium die cast.



03 High-Vacuum Die Cast (ACTIV-VD)

A Breakthrough in High-Quality Die Cast
ACTIV-VD is a development process that combines our unique Die-Cast technologies with our special product development technologies. The super high-speed machine of ACTIV-VD realizes high-quality die-casting of excellent heat treatment and welding, integrating a series of technologies such as die-cast design, high-vacuuming, and die structure design.
