The type metal is poured into ingot molds – small molds for manually feeding the metal pots or larger molds for the metal feeders. (In the latter case, special attention must be given the ‘eye’ end as it has to support the weight of the entire ingot. Failure often results in it dropping into the pot and splashing molten metal everywhere.)

Molds are considered to be microbes and do not form a specific taxonomic or phylogenetic grouping, but can be found in the divisions Zygomycota and Ascomycota. In the past, most molds were classified within the Deuteromycota. [5] Mold had been used as a common name for now non-fungal groups such as water molds or slime molds that were once ...
An American-style 15×15 crossword grid layout. A crossword (or crossword puzzle) is a word game consisting of a grid of black and white squares, into which solvers enter words or phrases ("entries") crossing each other horizontally ("across") and vertically ("down") according to a set of clues. Each white square is typically filled with one ...
Mold cavity: The combined open area of the molding material and core, where the metal is poured to produce the casting. Riser: An extra void in the mold that fills with molten material to compensate for shrinkage during solidification. Gating system: The network of connected channels that deliver the molten material to the mold cavities.
Low-pressure permanent mold (LPPM) casting uses a gas at low pressure, usually between 3 and 15 psi (20 to 100 kPa) to push the molten metal into the mold cavity. The pressure is applied to the top of the pool of liquid, which forces the molten metal up a refractory pouring tube and finally into the bottom of the mold.
Leaf mold (spelled leaf mould outside of the United States) is the compost produced by decomposition of shaded [1] deciduous shrub and tree leaves, primarily by fungal breakdown in a slower, cooler manner as opposed to the bacterial degradation of leaves.
Its principal use is in making molds for metal casting. The largest portion of the aggregate is a sand, usually silica or sometimes olivine . [ 1 ] There are many recipes for the proportion of clay, but they all strike different balances between moldability, surface finish, and ability of the hot molten metal to degas.
