Investment casting, also known as lost-wax casting, is a metal manufacturing process where a wax pattern of the part is coated with a ceramic material to form a hardened shell. The wax is then melted out, and molten metal is poured into the hollow ceramic mold. Once cooled, the shell is broken away to produce a highly detailed metal part with excellent surface finish and tight dimensional tolerances, often requiring minimal machining.
Canadian manufacturers may choose to offshore production of some parts to reduce manufacturing costs, access specialized production capabilities, and increase overall competitiveness. Offshoring can provide access to advanced tooling, higher-volume production facilities, or materials that are not readily available domestically. By strategically offshoring select components, manufacturers can improve supply chain flexibility, shorten lead times for certain products, and focus Canadian operations on higher-value activities such as engineering, assembly, and quality control.
Here is a list of automotive parts that are commonly made using investment casting, particularly where precision, complex geometry, and smooth surface finish are important:
Turbocharger turbine wheels
Exhaust manifolds (high-performance or stainless steel designs)
Fuel injector components
Valve bodies and valve components
Rocker arms
Gear selector forks
Throttle bodies (certain designs)
Brake system components (caliper parts, brackets)
EGR valves and housings
Sensor housings and mounts
Transmission shift components
Suspension links (lightweight or performance designs)
Differential and drivetrain brackets
Investment casting is often chosen for these parts because it enables complex shapes, thin walls, and fine details while reducing the need for secondary machining.
