Hopper-mould
From Warhammer 40k - Lexicanum
Hopper-moulds are Imperial devices, that Space Marines use to create prefabricated defense wall segments.[1]
Description
After large amounts of material is poured into them, the moulds then unleash a great amount of heat and pressure to crush it into shape. Once they are done, Fresh, steaming defense wall segments are dropped onto to the ground to be dragged into place.[1]
