Low pressure die casting, LPDC, is a process in which a ceramic tube is connected to a steel die above and extends into a furnace of molten metal below. The furnace is then pressurized to fill the part by forcing fluid up through the sprue. Once the casting has solidified the air pressure is reduced allowing the rest of the metal still in liquid form in the tube to recede back into the furnace. Low pressure die casting is used for high production rates, thicker parts up to 2.5 mm, for better surface quality, and when high temperature heat treatment is needed to improve strength. FLOW-3D Cast can be used to better design many aspects of a low pressure die casting through modeling thermal die cycling, filling, and solidification including thermally induced stresses and displacements. Better designs before production help alleviate trial and error through experimentation and bring designs to production more quickly. Both of which help save time and reduce costs.
