The raw materials are added to the pouring mixer after accurate measurement according to the set recipe, and the mixed materials are evenly stirred in the pouring mixer, and the stirred slurry is poured into the mould.

In the production of plates, the pin-inserting hoister inserts the assembled steel mesh cage into the slurry.

The mould bearing the slurry is transported by the ferry cart to the pre-curing room for static maintenance, and the slurry in the mould completes the gas hardening in the pre-curing room to form a blank cake.

The mould is transported to the cutting area by the pre-curing ferry cart. During production, the pin-drawing  is completed in this process.

Main equipment in this section are slurry and powder batching system, aluminum powder automatic measuring and mixing system, pouring mixer, pin-inserting and pin-drawing out hoister, pouring ferry cart, pre-curing ferry cart, friction wheel, etc.
