Aluminum Sand Castings

Castek aluminum sand castings are used to manufacture a variety of molds for industrial, commercial and ornamental applications. We support thermoform, reaction injection molding (RIM), and compression form market segments. Our mold-style aluminum castings typically contain stainless steel water lines for optimum temperature control during manufacture, which are often connected to a manifold system. This minimizes the lengths of internal water lines and therefore provides rapid heating and cooling of our molds. 

Castek’s aluminum sand castings are used for the following processes:

  • Automotive carpet forming molds
  • Vacuum form, pressure form, and thermoforming molds
  • Reaction Injection Molding (RIM) and Dicyclopentadiene (DCPD) molds
  • Polyurethane and foam molds
  • Long Fiber Injection (LFI)
  • Resin Transfer Molding (RTM)
  • Secondary fixtures (i.e., router trim fixtures and assembly fixtures)

Why choose Castek?

Castek is an industry leader in commercial-grade and mold-style aluminum sand casting technology. We are continuously refining our casting process variables to improve the clarity and reduce surface porosity of our products. Our air set, or “no bake,” molding operation is ideal for manufacturing large castings that green sand foundries cannot produce. The air set molding process gives the cope and drag sands greater strength and ensures proper casting tolerance and dimensions. Beyond manufacturing higher quality products, Castek’s aluminum sand casting technology is a significantly more economical choice when compared to conventional aluminum billet materials.
