Castool Tooling Systems – Die Cast Toolings (Plunger Sleeves)

The shot sleeve is a critical element of the aluminum die cast process. For maximum productivity – and also maximum operating life for both shot sleeve and plunger tip – the plunger must consistently move smoothly, and at a steady speed through a perfectly round, straight, shot sleeve. This does not always happen however, because when heated, metal expands. If partially filled with hot molten alloy, the shot sleeve will become distorted.
