Sand casting is one of the oldest and most widely used casting processes in the manufacturing industry. It involves creating a mold from sand and then pouring molten grey cast iron into the mold cavity. The process begins with the preparation of a mold, which consists of two halves the cope (upper half) and the drag (lower half). The sand is mixed with a binder, usually clay, and water to create a mold that can hold its shape when the molten metal is poured.

The process of investment casting begins with creating a wax pattern of the desired component. This pattern is then coated with a specially formulated ceramic shell, which hardens upon application. Once the shell is set, the wax is melted away, leaving a precise cavity for the molten metal. This method allows for exceptionally tight tolerances, often within a few thousandths of an inch, making it suitable for components that require high accuracy and reliability.

Stainless steel is a popular choice for investment casting due to its excellent mechanical properties and corrosion resistance. Here are a few advantages

Choosing the correct wall thickness can significantly influence the overall cost of die-cast components. While thicker walls may seem appealing for strength, they often lead to increased material usage and extended processing times, both of which drive costs up. Conversely, overly thin walls may necessitate rework or lead to premature part failure, resulting in increased costs related to warranty claims and replacements.
