Types of Aluminum Ingot Molds
Standard Ingot Molds
Standard ingot molds are typically made from steel or aluminum and are designed for general aluminum casting applications. These molds are often used for various alloys and are available in multiple sizes, allowing for flexibility in production. They are suitable for both small-scale operations and larger foundries.
Water Hole Molds
Wagstaff’s Water Hole ingot mold is a prime example of a specialized aluminum casting mold. This mold has been utilized for decades in direct chill casting processes. Machined from a solid block of aluminum, these molds offer superior structural integrity. They are particularly suited for applications requiring high-quality aluminum sheet ingots, making them a popular choice in industries focused on efficiency and quality.
Low Head Composite Molds
Innovations in casting technology have given rise to low head composite molds, such as the ones offered by Wagstaff. These molds are designed to enhance ingot quality and improve recoveries. They allow for increased casting speeds and reduced lubricant consumption, making them an environmentally friendly option. Custom widths and fixed dimensions make them adaptable to various production needs.
Clay Graphite Molds
Clay graphite molds are commonly used for casting precious metals like gold and silver. They are smaller and more specialized compared to other aluminum ingot molds. These molds are often used in jewelry making and small-scale metalworking operations, where precision is crucial. Customization options are limited, but they provide excellent heat resistance and durability.
Foundry Ingot Molds
Foundry ingot molds are reusable molds ideal for casting aluminum and zinc. Companies like Pyrotek offer these molds with options for air-cooled and water-cooled applications. The ability to customize the chemistry and alloy composition allows for versatility in production, catering to specific industry requirements.
Applications of Aluminum Ingot Molds
