Gravity Die Casting

Gravity Die Casting is a low tech process, its well suited for batch production of simple forms without undercuts.

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

Gravity Die Casting requires minimal finishing, and waste content is minimal, as the excess metal can be used again.

Sheet Metal Punching

Sheet Metal Punching is used for components requiring a series of holes to be cut out in them it is often quicker to punch rather than to drill.

This Process is carried out on a hydrolic press using a hardened steel punch and die set.
