Sand casting is a typical manufacturing process for metal parts with complex geometries and low to medium production volumes. It involves creating reusable molds and cores from sand, then pouring molten metal into the cavity to form near-net-shape castings. Custom sand casting services create these molds based on each customer’s unique specifications. But is custom sand casting cost-effective compared to CNC machining service or injection molding service ? Here are the key factors to consider: Lower Initial Costs The main advantage of custom sand casting is significantly lower tooling costs than die casting service or metal injection molding (MIM) . Only a one-time sand mold and core package must be produced per unique part geometry. Once the initial prototypes are approved, rapid iteration and adjustments are possible with sand molds. It avoids the expensive CNC machining of hardened steel tooling. Total upfront costs for simple cast geometries can be under $2,000 . Even com
