Our technology

Magnesium alloys are the lightest in a practical metal. And magnesium alloys have the following three features.

  1. Lightness ( Mg : Al = 1.82 : 2.67 )
  2. Liquidity ,it is easy to make it thinly.
  3. Specific heat is small. It is easy to heat and cools.

Parts corresponding to all needs such as "Lightness", "Thin", and "Miniaturization" requested from a recent manufacturing premise can be built by making the best use of these features to its maximum.

Magnesium product

When "Lightness" that was the best feature was made the best use of when magnesium alloys were produced, the knowhow to bring it close to the customer’s demand in all QCD had been cultivated in the ST group. The magnesium products that achieve mass production for the customer’s demand are the following.

Auto parts Steering wheel key lock ,Oil cover
Projector etc Camera for professional ,Projector ,Single lens reflex camera
Cellular phone ,Personal computer ,Electronic book Liquid crystal holder for cellular phone ,Exterior and interior parts for personal computer ,Substrate for electronic book
Power tool Chainsaw ,Brush cutter cover ,Pegger case ,Driver cap
Others Launch pad tower of Pachinko ,Radio controller ,Medical equipment case ,LED lighting heat sink
  • Motorcycle parts
  • Parts of note type computer
  • Parts of cellular phone

Enhanced equipment

The enhanced equipment that specializes in the magnesium die casting and manufactures parts is arranged for the achievement of mass production.

Die casting machine 600 ton Hot chamber(IDRA) 2 Total 13
300 ton Hot chamber(IDRA,UBE,Tosiba) 10
150 ton Hot chamber(Hishinuma) 1
Mechanical processing center Made by Funac 19 Total 44
Made by BROTHER etc 25

Magnesium alloys cannot be built only by equipment. It has the metal mold and the foundry technique that matches to the manufacturing method and it is possible to meet wide range of needs for the first time.

Superior knowhow that can make use of the enhanced equipment and those abilities in the maximum is our strong point.
