Squeeze Casting VS Forging

Squeeze casting and forging are both metalworking processes used to create parts, but they differ in their approach:

Squeeze Casting (Liquid Metal Forging):

• Process: Combines casting and forging. Molten metal is poured into a heated die, then pressure is applied as it solidifies. This pressure forces the metal to fill the mold completely and reduces defects.
• Strengths:
  • High-quality parts with excellent surface finish and minimal porosity.
  • More complex shapes possible than traditional forging.
  • Wider range of metals than forging (aluminum, magnesium, and some others).
• Weaknesses:

• More expensive than traditional casting due to complex machinery.
• Slower production times compared to forging.

Forging:

• Process: Solid metal is heated to a plastic state and shaped using compressive force (hammers or presses). The metal grain is refined, improving strength.
• Strengths:

• Excellent strength-to-weight ratio and fatigue resistance.
• Faster production times than squeeze casting.
• Generally less expensive than squeeze casting.
• Weaknesses:

• Limited to simpler shapes due to forming method.
• Fewer metals can be forged compared to squeeze casting (mostly steels).

Choosing Between Them:

• Strength and Durability: Forging is generally better for parts requiring maximum strength.
• Complexity: Squeeze casting offers more design freedom for intricate shapes.
• Cost: Forging can be cheaper for simpler parts, while squeeze casting might be cost-effective for complex parts requiring high quality.
• Material: Consider the type of metal best suited for your application.

In summary, squeeze casting offers a good compromise between the formability of casting and the strength of forging. The best process depends on your specific needs for the part you’re creating.
