Abstract

Flexible cooling channels with different cross sections are fabricated in injection molding using laser metal sintering. To make cooling uniform and to speed up cooling, we investigate several basics to be considered in designing cooling channels as related to the properties of sintered metal and restrictions on lamination sintering. Placing cooling channels in the corner of the core or in ribs between grooves kept molding temperatures uniform and improved the precision of the molded work piece shape. Fabricating cooling channels in the conical core reduced injection molding cycle time by speeding up cooling.
