Precision casting is a manufacturing process that creates complex and high-accuracy metal components by forming multiple ceramic shell layers around a wax pattern. This technique allows for exceptional dimensional control, smooth surface quality, and near-net-shape production.
At Quintex, we use precision casting because it provides consistent quality and ensures reliable performance for demanding industries such as automotive, oil & gas, food machinery, and industrial equipment.
Wax Pattern Creation:
The process begins with the production of wax patterns, which are replicas of the final stainless steel product. These patterns are typically created using an injection molding process to ensure precision.
Assembly of Patterns:
Shell Building:
The wax patterns are then assembled onto a central runner system to create a tree-like structure, optimizing the casting process and allowing for multiple parts to be cast simultaneously.
The assembled wax patterns are coated with a ceramic shell. This is done by dipping the pattern into a liquid ceramic slurry and then sprinkling fine sand onto it. The shell is allowed to dry and harden, forming a strong mold.
Wax Removal:
Once the shell is solidified, the wax is melted and drained away, leaving a hollow ceramic shell that will form the shape of the final product.
Casting:
Molten stainless steel is poured into the preheated ceramic shell. The metal fills the cavity, taking on the shape of the original wax pattern.
Quality Inspection:
Finally, each part is rigorously inspected for quality and compliance with industry standards before being packaged and shipped to customers.
