Magnesium alloys are the lightest in a practical metal. And magnesium alloys have the following three features.
- Lightness ( Mg : Al = 1.82 : 2.67 )
- Liquidity ,it is easy to make it thinly.
- 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.
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|
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.
Correspondence to product with which size accuracy is severe
It corresponds to a severe tolerance of size to casting material.
Product size φ60×25mm Thickness Basic thickness:2.5mm
Weight 26g Basic tolerance Basic tolerance: ±0.03
Minimum tolerance: ±0.015
It corresponds to the levelness which demanded by the casting material.
Product size 195mm×115mm×5mm Thickness Basic thickness:0.8mm Minimum
Weight 32g Basic tolerance ±0.05 平面度 0.15 or less
Even if it is a big product, the thinness only to being able to endure the externals quality is achieved.
Product size 400ｍｍ×400ｍｍ×75ｍｍ Thickness Basic thickness:1.5mm
Weight 800g Basic tolerance Basic tolerance: ±0.2
Minimum tolerance: ±0.05
