Chrome die-cast handle.
Handle in chromium-plated die-casting, Flex made using the die-casting technique also called shell foundry under pressure, is a particular foundry process in permanent form, in which molten metal is injected at high pressure into a metal mold. The mold (more properly called form in the specific case of metals) consists of two half-molds generally of steel or cast iron, so the metals used in the process will be all materials that melt at lower temperatures, such as aluminum alloys, zinc or magnesium. The injection pressure of the molten metal can vary from 2 to 150 MPa depending on the case: the pressure is maintained for the entire duration of the process until solidification occurs, while hydraulic presses guarantee the closure of the mold even at high operating pressures. To ensure the cooling of the piece, there is a liquid circulation system inside the mold. Once the piece has solidified and cooled, the presses open the two molds so that it can be picked up.
