Investment Casting can be great for very complex, intricate parts that require thin walls.  For common parts that do not meet those project criteria or are larger than a 100 pounds, then this is not a good solution.  High costs for tooling  are also an issue.  The surface finish from Investment Casting does provide a huge benefit and often negates the need for secondary machining.  As most of us know, machining is a major cost contributor, so this is a major boost.  More Detail

Sand Casting is the most widely used casting process. Sand Casting 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, sand casting typically has a lower production rate. The Sand Casting process involves the use of a furnace, metal, pattern, and 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. More Detail

Ceramsite sand is also called Ceramiste, Ceramic Foundry Sand and Nice Foundry Sand. It is a new artificial foundry sand, with better comprehensive property and price comparison, it is
now regarded as the right substitute for chromite sand, zircon sand, fused silica sand and cerabeads. It is weel regarded as a revolution for new fourndry sand. More Detail
