Aluminium forging Hanging board 6063

Hanging board used for electricity industry Most aluminum alloy forgings are produced in closed dies. The four types of aluminum forgings shaped in closed dies are blocker-type (finish forging only), conventional (block and finish forging or finish forging only), high-definition (near-net shape produced by forging in one or more blocker dies followed by finish forging), and precision (no draft, net shapes produced by forging with or without blocker dies followed by two or more finish forging steps in the finish dies). Blocker-type forgings are produced in relatively cheaper, single sets of dies. In dimensions and forged details, they are less refined and require more machining than conventional or high-definition closed-die forgings. A blocker-type forging costs less than a comparable conventional or high-definition forging, but it requires more machining.
