Investment Lost Wax Gravity Sand Casting is a hybrid manufacturing process that combines the precision of investment casting with the versatility of sand casting. This method involves creating a wax model of the desired part, which is then coated with a ceramic shell. The wax is melted away, and the resulting cavity is filled with molten metal using gravity pouring. The sand mold provides additional support and allows for the production of larger and more complex parts. This process is particularly useful for creating components that require a high level of detail and dimensional accuracy, while also being cost-effective for larger production runs. The resulting castings are strong, durable, and suitable for a wide range of applications, including automotive, industrial machinery, and fluid control systems.
