With our coordinate measuring machines, we ensure that our process meets customer standards.

Sand, Permanent & Other Types of Casting Sourcing & Machining

When die-casting doesn’t make sense for a product, we have many other options available to our customers. PHB Machining has a large group of casting suppliers we can call on to choose the best process and material for your application. Below are some examples of the processes PHB can provide:

Sand Casting Supplier | Casting Machining & Sourcing

Sand casting, the most widely used casting process, utilizes expendable sand molds to form complex metal parts that can be made of nearly any alloy. Because the sand mold must be destroyed in order to remove the part (also known as the casting), sand casting typically has a low production rate. The sand casting process involves the use of a furnace, metal, a pattern, and a sand mold. The metal is melted in the furnace and then ladled and poured into the cavity of the sand mold, which is formed by the pattern. The sand mold separates along a parting line and the solidified casting can be removed.

Permanent Mold Casting Sourcing and Machining

Permanent mold casting is a metal casting process that shares similarities to both sand casting and die casting. As with sand casting, molten metal is poured into a mold which is clamped shut until the material cools and solidifies into the desired part shape. However, sand casting uses an expendable mold that is destroyed after each cycle. Permanent mold casting, like die casting, uses a metal mold (die) that is typically made from steel or cast iron and can be reused for several thousand cycles. Because the molten metal is poured into the die and not forcibly injected, permanent mold casting is often referred to as gravity die casting.

Permanent mold casting is typically used for high-volume production of small, simple metal parts with uniform wall thickness. Non-ferrous metals are most commonly used in this process, such as aluminum alloys, magnesium alloys, and copper alloys; however, iron and steel can also be cast using graphite molds. Common permanent mold parts include gears and gear housings, pipe fittings, and other automotive and aircraft components such as pistons, impellers, and wheels. 

Investment Casting Supplier | Vaccum Casting Machining & Sourcing

Investment castings, which are often referred to as lost-wax castings, are metal parts that are produced by the investment casting process. This expendable mold process (along with the components it produces) is extremely popular for countless applications in numerous industries. This is largely due to the fact that the investment casting process makes it possible to create complex parts with exceptional surface quality and accuracy in a wide range of materials and sizes. However, if a part requires intricate details or undercuts, the material is reinforced by fiber or wire. If air entrapment is a problem, a specific type of investment casting method is used. This investment casting technique is none other than the vacuum casting method, which produces vacuum castings. 

Vacuum castings are the metal parts that are produced by the vacuum casting method. They are different than typical investment castings due to the technique that is used to create these metal parts. The process begins by placing a two-piece mold in a vacuum chamber. The vacuum then draws the molten metal into the mold. Finally, the casting is solidified in an oven and the mold is removed in order to release the final product.
