Die casting, alternatively, makes use of pressurized injection to drive liquid aluminum into a metal die, resulting in precise dimensions and smooth surfaces. This process is well-suited for high-quantity manufacturing, delivering outstanding consistency and structural durability.
Investment casting, commonly referred to as the lost-wax method, is based on producing a wax model encased in a ceramic coating. Once the wax is melted away, liquid aluminum is cast into the mold, creating detailed components with fine detail. Every method provides distinct advantages, accommodating various manufacturing needs and applications in the aluminum casting sector.
What Happens in the Aluminum Casting Process?
The aluminum casting procedure begins with melting the metal at high temperatures until it becomes molten.
