Principles for Selecting Casting Methods in Lost Foam Mold Applications
Priority to Sand Casting
Sand casting should be primarily adopted due to its cost-effectiveness, simplified production processes, and shorter lead times. Transition to clay-bonded sand with surface-dried molds, dry sand molds, or alternative sand systems only when green sand proves inadequate. Clay green sand accommodates castings ranging from a few kilograms to dozens of kilograms, while clay dry sand systems support castings up to dozens of tons.
Batch-Production Alignment
Advanced methods such as low-pressure casting, die casting, and centrifugal casting require substantial investments in specialized equipment and molds, rendering them economically viable exclusively for mass production scenarios.
Precision-Cost Optimization
Method selection must strategically balance dimensional accuracy requirements with overall cost efficiency, ensuring technical feasibility without compromising economic rationality.
Casting Hole
In other types of casting methods, casting holes can be obtained through sand cores or by machining (e.g. drilling). For each casting, whether the casting hole has its corresponding characteristics, but in general, the casting hole reduces the cost of subsequent machining. Through special mold design such as the use of pins. The mandrel or other mechanism can make the casting hole directly on the mold.
Furthermore, our EPC mold design can greatly reduce the machining allowance required for castings. By minimizing die tilt and machining allowance, our mold design offers a flexible and efficient solution that is unmatched by many other casting methods. This results in significant cost savings and improved accuracy in the final product.
