Casting is preferred for more complex shapes while forging is ideal for simpler, high-strength parts
Forging can be more cost effective for large production runs of simpler shapes, whereas casting can be more economical for small to medium batches, especially of complex parts.
Initial setup costs for casting molds can be high, but per-unit costs decrease with volume. Forging requires significant investment in tooling and machinery, especially for high-volume production.
If the application requires specific alloy properties, casting may offer more flexibility. For applications where material strength and integrity are paramount, forging is often the better choice.
