Investment Casting Process Method
Complete Guide to Lost Wax Investment Casting Process
Why Investment Casting?
Design flexibility
Investment casting produces near-net-shape configurations, offering designers and engineer’s freedom of design in a wide range of alloys. The process is capable of producing precise detail and dimensional accuracy in parts weighing few grams to many kilograms.
Wide range of alloys
Many ferrous and non-ferrous alloys are routinely cast at BCPL.
Reduction of production costs
Costly machining operations are reduced and often eliminated. No capital equipment investment is needed to produce parts in-house.
Reduction of assembly operations
Several parts can be made as one casting, reducing handling, assembly and inspection costs.
Reproduction of fine details
Splines, holes, bosses, lettering, serrations and even some threads can be cast.
Consistency of Components
Since cast components are produced by using wax patterns from a single tool, dimensional accuracy is the same from part to part, year after year. When design changes are required, it is usually possible to alter existing tooling at a relatively minor cost.
- Near-net-shape output — Reduces or eliminates costly machining operations.
- Design flexibility — Produces complex shapes, splines, holes, bosses, serrations, and even some threads.
- Wide alloy range — Both ferrous and non-ferrous alloys are routinely cast.
- Consistent accuracy — Wax patterns from a single tool deliver the same dimensional results part after part, year after year.
- Fewer assembly operations — Multiple parts can often be consolidated into a single casting.
- Low tooling modification costs — Design changes can typically be made to existing tooling at relatively minor cost.
