Taisei Kogyo has developed the smallest check valve made by MIM technology with the aim to reach a size as small as \u03c62.4mm, which was considered the limit of such check valve production by MIM technology. A check valve is a valve that normally allows liquids or gas to flow through it in only one direction. In some check valves a spherical ball is used to block or release the flow. These check valves have a wall thickness of 200\u03bc.<\/p>\n

This is a good example of the \u03bc-MIM technology which also enables the company to build metal parts with a wall thickness of under 100\u03bc and a special sacrificial inner mold. Taisei Kagyo is able to mass produce small parts like the check valve. [Source<\/a>]<\/p>\n
