日本九州柳河公司和本田公司近日合作开发出铸造新方法。利用此方法可以制造空心结构而且能焊接的铝合金压铸造件,在保证产品高刚性的同时可以实现轻量化。该方法在按预定形状烧结成形的型芯表面上涂覆铝合金材料,从而避免了铝合金在型芯上的附着、渗透。使用此方法铸造最薄壁 Japan Kyushu Liuhe Company and Honda recently co-operation to develop a new casting method. This method can be used to make hollow structure and can be welded aluminum alloy die-casting, to ensure high-rigidity products at the same time can be reduced weight. In the method, the aluminum alloy material is coated on the surface of the core which is shaped by sintering in a predetermined shape so as to avoid the adhesion and infiltration of the aluminum alloy on the core. Use this method to cast the thinnest wall
