An Example in Steel Casting    Hinge/Bearing Assembly for Log Forwarder

     Design for Castability

Casting engineers produce castings of almost any design and complexity, achieve high quality, and meet performance and cost targets by insuring that “castability” is considered in the basic design.

Designing for castability insures that sound castings are consistently produced and production costs are minimized.

The foundry engineer plans how the casting will be produced in the mold considering --

  • A review of the hinge and bearing components identified four castability design issues

-- Coring versus Machining
-- Reducing Hot Spots
-- Runners and Ingates
-- Riser Size and Positioning

--- The positioning the piece in the mold and location of the parting line.

--- The location of sprues, runners and gates for metal flow into the mold.

--- The use of cores for internal features.

--- The location and size of risers to provide metal for solidification.
