Gravity Die Casting

Daften Die Casting Ltd use the gravity die casting process to manufacture sarcrificial anodes for marine vessels. This is a low-tech process is well suited for the batch production of simple forms without undercuts

Mazak, an alloy of zinc and aluminium, is first melted in a crucible furnace. Molten metal is then poured by ladle into a open steel mould where it is allowed to cool and solidify. The mould is then turned upside down and tapped with a hammer to release the finished casting.

Sheet Metal Punching

For components requiring a series of holes to be cut in them, it is often quicker to punch rather than drill.
Holes are punched in 12mm mild steel plate. This operation is carried out on a hydraulic press using a hardened steel punch and die set.
