Secondary Processing Changing industrial materials into finished products. Six different activities: Changing industrial materials into finished products. Six different activities:

Casting and Molding Pouring or forcing liquid material into a prepared mold. It solidifies then is removed from the mold. Pouring or forcing liquid material into a prepared mold. It solidifies then is removed from the mold.

Forming Using force to cause a material to take permanent shape, using a die, mold, or roll. Using force to cause a material to take permanent shape, using a die, mold, or roll.

Separating Converting a material to size and shape by removing excess material through cutting or shearing. Converting a material to size and shape by removing excess material through cutting or shearing.

Conditioning Using heat, mechanical force or chemical action to change the internal properties of a material. Using heat, mechanical force or chemical action to change the internal properties of a material. –Drying –Heat treating –Firing
