Metal Casting Processes Overview
Metal casting processes are broadly categorized into two main branches:
Expendable Mold Casting Methods:
The mold used in this process is designed for a single use, producing only one metal casting. Expendable molds allow for the creation of intricate geometries. Typically, binders such as plaster, sand, or similar materials are employed to help the mold maintain its form throughout the casting process.
Permanent Mold Casting Methods:
In contrast, permanent molds have sections that can open and close, enabling the production of multiple castings. However, the shapes achievable with this method are somewhat limited. Permanent molds are typically crafted from metal or other refractory materials.
Expandable molds, constructed using materials like sand, plaster, and ceramics, exhibit resilience to high temperatures. On the other hand, permanent molds, made from metals, retain strength even under high-temperature conditions. They are reusable multiple times and can withstand numerous casting operations.
Metal casting processes are available in a variety of types. Selecting the right type for your project depends on:
- Materials
- Required Surface finishes and tolerances
- Costs per part
- Tooling costs
- Production Volume
Casting Imperfections and Solutions
The intricate process of metal casting within foundries introduces complexity. Quality assurance is paramount, involving a diverse array of inspection methods to identify potential defects. Regardless of the casting method—be it investment casting, sand casting, or other metal casting techniques—it is susceptible to various defect types. Undesirable as they are, defects can manifest in different forms, including surface irregularities, inclusion flaws, molding and pouring issues, and cooling-related defects
At Kohinoor, we provide tailored casting inspection methods designed to uncover any concealed defects throughout the manufacturing process.
