Japanese facility casts ultrathin components.Kyoei Wooden Pattern & Foundry Co. Ltd., Hiratsuka City, Japan, has developed and manufactured sand mold castings with sections as thin as 1mm. The company, which casts aluminium alloys Aluminium alloys or aluminum alloys are alloys of aluminium, often with copper, zinc, manganese, silicon, or magnesium. They are much lighter and more corrosion resistant than plain carbon steel, but not quite as corrosion resistant as pure aluminium. and stainless steel stainless steel: see steel. stainless steel Any of a family of alloy steels usually containing 10–30% chromium. The presence of chromium, together with low carbon content, gives remarkable resistance to corrosion and heat. , produced the ultrathin ul·tra·thin adj. Very thin. castings by heating the sand mold to a high temperature. The technique can be applied to various types of metals including stainless steel, aluminium alloys and copper alloys Copper alloys are alloys with Copper as their principial component. They have high resistance to corrosion. Due to its high electric conductivity, pure electrolytic copper is used mostly for making of electrical cables. . The mold heater for ultrathin sand mold casting has already been patented in Japan. |
