Casting and Molding

Casting and Molding Videos

Separating • Involves the removal of material • Also referred to as the subtractive process • Includes two types of processes – Chip Forming – Non-Chip Forming

Separating Videos

Joining • Also referred to as the additive process • Materials added in layers to build a finished part • Examples – – Welding Gluing Soldering Prototyping

Forming • Uses force to cause a material to permanently take a shape • Changes some of the material properties

Forming Videos

Finishing • May be completed before or after assembly • Used primarily to protect a product from various conditions • Also used to enhance a product’s appearance

Finishing: Deburring • Methods include filing, scraping, and trimming • Considerations include actual requirements regarding work piece specifications, production quantities, and cost

Finishing: Cleaning • Involves the process of removing unwanted material from work pieces • Techniques include – Alkaline cleaning – Electrolytic cleaning – Solvent cleaning – Vapor degreasing – Acid cleaning – Abrasive blasting – Abrasive wheels

Finishing: Coating • Involves a material being applied to a work piece • May be mechanical, electrolytic, or conversion

Finishing: Assembling • Involves putting parts together • May be temporary or permanent • Includes bonding and mechanical fastening

Finishing: Conditioning • Refers to changing the physical or mechanical properties of a material • Includes thermal, chemical, and mechanical
