LARGE CASTINGS IN NO-BAKE

Over the years, No-bake molding has proven its worth as an efficient means to produce low and medium volumes of complex castings. H & H Castings is now equipped to help its customers obtain large castings on time and reasonably priced. Parts with weights up to 300 pounds are ideal candidates for this process.


TOOLING

In green sand molding, compaction forces are required to pack the mold. In No-bake molding, little, if any force is needed thereby shrinking the wear and tear factors normally seen in green sand mold making. Wood and plastic are the materials of choice in making the No-bake molds. Innovative tooling options increase the engineer's ability to design complex configurations. Many of the same principals used in green sand molding can be applied to the design of parts made by the No-bake process and more liberties can be taken during the design stage.

BENEFITS OF NO-BAKE

  • Design tolerances of +/- .015 up to 6", +/-.003 per inch beyond 6"
  • Gas-related defects are minimized as Nitrogen content of binders reduces gas porosity
  • Finer surface finishes
  • Finishes in 200 - 250 RMS range can be repeated, reducing finishing expense
  • Decreased costs due to shortened paint and powder coating prep time
