Aluminum Investment Casting
Aluminum investment casting (lost-wax casting) is a precision manufacturing process ideal for complex, high-performance components. It involves:
Wax Pattern Creation – 3D printing or injection molding for intricate designs.
Ceramic Shell Building – Dipping in refractory slurry for a high-strength mold.
Dewaxing & Preheating – Wax melts away, leaving a hollow ceramic mold.
Molten Aluminum Pouring – Filling the mold via gravity, vacuum, or centrifugal casting.
Cooling, Shell Removal & Finishing – CNC machining, heat treatment, and surface treatments for final precision 511.
Features of Aluminum Investment Casting
🔹 Complex Geometries – Produces intricate designs with internal cavities.
🔹 Tight Tolerances (±0.005 inches) – Minimizes post-casting machining.
🔹 Superior Surface Finish (60-200 RMS) – Reduces secondary finishing needs.
🔹 Lightweight & Durable – Ideal for aerospace and automotive applications.
🔹 Material Versatility – Works with alloys like A356, A380, C355, and F357 for varied mechanical properties 211.
