Standards & Properties: Metallurgy of Copper-Base Alloys

Casting in sand or chill molds are ideal production methods ideal for very small runs or very small parts and are sometimes mandatory for very large parts such as ship propellers. All of the alloys discussed are available in these forms, although problems with severe lead segregation may occur as the lead content approaches 16%.

Spin casting - Wikipedia

Spin casting, also known as centrifugal rubber mold casting (CRMC), is a method of utilizing inertia to produce castings from a rubber mold.Typically, a disc-shaped mold is spun along its central axis at a set speed. The casting material, usually molten metal or liquid thermoset plastic, is then poured in through an opening at the top-center of the mold.

Investment Casting - an overview | ScienceDirect Topics

The investment casting method, also called the lost wax process, is used for precision casting of aerospace components such as gas turbine blades. The investment casting of aluminium alloys results in lower strength than sand castings, but offers tighter tolerances, better surface finish and the capability to produce thin-walled sections.

Casting Process - an overview | ScienceDirect Topics

In this casting process the liquid is injected under pressure that is far less than conventional injection molding (Chapters 4 and 16). A simplified view of this casting process is shown in in Figure 11.1. For more precision mixing, equipment is available such as the schematic shown in Figure 11.2.
