Precision Investment Lost Wax Casting Parts

Difference Between Lost Wax and Investment Casting

• Lost Wax Casting: Traditional technique using wax patterns to create molds for complex shapes.
• Investment Casting: Modern term for lost wax casting emphasizing precision, repeatability, and suitability for mass production.
• Both produce high-accuracy parts, but investment casting integrates CAD, CNC machining, and quality control for industrial standards.
