Casting Process

At Quality Non-Ferrous Foundry, we provide three types of casting processes. For lower-volume production runs, sand mold casting flexible process reduces tooling costs, simplifies mold production and reclamation, and allows reuse of molding materials. For larger, and more complex designs, nobake casting process is known for its versatility, with components weights ranging from less than a pound to larger weights. And for high-volume production runs, permanent mold casting processes can produce complex shapes and designs with finer grain structure, while allowing reuse of molds.

No-Bake Mold Process

The No-Bake Mold Process can be used with most types of non-ferrous metals and is optimal for dimensional control and precision over the mold. Sand is mixed with chemical binders to help maintain proper temperature and density—two critical aspects in the molding processes. No-Bake is ideal for detailed, high-strength casting requirements. Mold sizes and batch quantity can range from very large to very small, offering better finishes than cast products and other molding processes.

Features

  • High strength mold
  • Better dimensional control
  • Improved dimensional repeatability

Sand Mold Process

The lower cost pattern and material Sand Mold Process, forms molds by using a high-density, hard-packed casing of chemically bonded sand. The process, adaptable to large or small quantities, uses a hydraulic hard-sand-packing method to improve the casting standards of accuracy and finish, while still maintaining mold flexibility for almost unlimited sizes, weights and heights. Sand molding can be used with most non-ferrous metals and is adaptable to large or small casting quantities.

Features

  • Low Pattern & Material costs
  • Almost no limit on size, shape or weight of part
  • Adaptable to large or small quantities

Permanent Mold Process

The Permanent Mold gravity process features superior casting capabilities and more accurate properties than other molding processes such as shell molding. It provides highly dense and uniform castings with high dimensional accuracy. Molten, non-ferrous metals are poured into basins which are then tilted at an angle, forcing gravity to feed the molds. The Permanent Mold process delivers excellent surface finish and grain structure parts and is typically the preferred process for light alloy cast components.

Features

  • Produces dense, uniform castings with high dimensional accuracy
  • Excellent surface finish and grain structure
  • Fast production rate with low scrap loss
  • Repeated use of molds
