General cast iron surface plate has many specifications, but its casting method is different. Casting method selection principles are many, such as casting method should be compatible with the production volume, taking into account the precision casting requirements and costs, modeling methods should be suitable for factory conditions. Here's a brief introduction to these principles.
A, casting method should be compatible with the production volume. They are low-pressure casting, die-casting, centrifugal casting and other casting methods, due to the expensive equipment and molds, it is only suitable for mass production.
B, Modeling methods should be suitable for factory conditions. The production of large machine bed castings generally use the core modeling method, not making appearance and sand box, while the other plant is used sand box modeling method, making appearance. Different production conditions and production habits, should be based on these conditions to consider this method.
C, the preferred use of sand casting, the casting method has the advantages of low cost, simple production process and short production cycle.
