Precision Casting vs Sand Casting
Sand casting is a casting process working by creating a cavity for casting by sand, and the sand shell will produce a rough shape. Normally the tolerances of sand casting are CT8-CT9, and the surface finish is around Ra250. So for sand cast products, the rough surface will well quire more machining operations than investment castings.
Precision casting creates desired shapes by a ceramic shell and can produce a much better surface finish product. We can meet a tight tolerance CT5-6 as precisely as possible, thus reducing net shape products and likely avoiding further machining.
Precision Casting vs Machining
For some easy products with a simple shape, we may choose either precision casting or machining. Machining is the process that machining a part into final dimensions from a bar directly. This will cause a large waste of raw material, which will imperceptibly add to the production cost. Besides, if the quantity is large, the single production will longer the production time, which will delay the lead time.
Precision Casting makes a product to be costly in further machining. CFS Foundry has both a casting workshop as well as machining shop. We can supply machined precision castings at the best price, allowing our customers to receive well-performed products that can be put into the application directly.
Precision Casting vs Precision Forging
Precision forging is the metal forming process that presses hot or cold metal bars into shapes directly. To withstand high pressure, there is a high requirement on the material of forging dies. The commonly used material for forging dies is tool die, whose cost is quite high. The high cost of tooling cost makes the precision forging process not competitive as precision casting. Also, precision forging has a district control on the shapes of products.
By comparison, precision casting requires less tooling cost and has no limitation on the dimensions of products. This makes our company available for all metal products.
Precision Casting vs Metal Fabrication
Metal fabrication is the process of cutting and bending metal plates into different shapes and thicknesses, and welding them together to form a product. This will cost more labor cost and production time.
Precision Casting can greatly reduce production time by attaching multiple wax models to a gate or system.
