DIE CASTING

• Metal casting process, characterized by forcing molten metal.
• The mold cavity created by two hardened tool steel dies.
• Using of either a hot- or cold-chamber machine is used.
• Most die castings are made from non-ferrous metals (specifically zinc, copper, aluminium).

MILLING

• Process of machining using rotary cutters to remove material. 
• Done by varying direction on one or several axes, cutter head speed, and pressure.
• Covers a wide variety of different operations and machines.
• on scales from small individual parts to large, heavy-duty gang milling operations.
• One of the most commonly used processes for machining custom parts to precise tolerances.

WELDING

• A fabrication process that joins materials, usually metals.
• Using high heat to melt the parts together.
• Allowing them to cool, causing fusion.
• Distinct from lower temperature techniques such as brazing and soldering, which do not melt the base metal (parent metal).
