With more than 65 years of metal casting experience, Richmond Foundry LLC can assist its customers in determining the best process and materials for their parts based on size, complexity, and volume.

Richmond Foundry LLC specializes in sand casting, the most widely used casting process. This process involves forming a mold cavity into bonded sand by using a pattern to create an impression, which is a duplicate of the actual part. The sand is contained in a metal flask. If required, a sand core is then placed in the mold to create an intricate cavity inside the casting. A core print is the region added to a pattern that is used to locate and support the core inside the mold. “Sprues” are formed to introduce the molten metal to the sand mold, “Gates” direct the metal to the impressions in the sand mold created by the patterns and “Risers” contain the excess molten metal to compensate for shrinkage as the casting solidifies. After cooling, the casting and sand are removed from the flask. The sand core is removed, resulting in an intricate detail inside the casting. Cleaning operations include cutting, grinding and shot blasting. At this point, the casting can undergo additional secondary operations including but not limited to machining, painting, anodizing, plating and coating if required by the customer.

Richmond Foundry LLC can cast from ounces up to 75 lbs. and specializes in low and high volume production runs.

Our foundry consists of two separate sand systems which feed an automatic Hunter HMP 14×19 and automatic BMM 20×20 (British Molding Machine). These molding lines are supported by six induction furnaces and three separate inductotherm power supplies.

At Richmond Foundry LLC, meeting customer requirements comes first. Upon completion of the tooling, we produce and evaluate samples to guarantee that the customer’s requirements have been met. Once sample approval is obtained from the customer, production is implemented. Richmond Foundry LLC utilizes a disciplined system of process controls to ensure that production castings meet customer requirements to ensure customer satisfaction.
