Patent ID: 8246891

Claim:
A method for manufacturing molded fatty acid based material products comprising: generating a fatty acid based material paste having a first temperature; the paste generation comprising heating a volume of the fatty acid based material with a heater for a period of time sufficient to bring the fatty acid based material to the first temperature at which paste consistency is established, and limiting the heater to a temperature that does not melt the material; injecting a portion of the fatty acid based material paste at the first temperature under pressure into a mold having at least two separable shells that form product cavities with gates that are sized to prevent elevation of the fatty acid based material paste above the first temperature, each shell of the mold having a temperature that is less than the first temperature of the injected fatty acid based material paste, the temperature of the shells enabling the injected fatty acid based material paste to form a skin upon contact with an internal surface of one of the mold shells; and separating the shells of the mold to release molded products from the product cavities.
