Square sprues for better casting results.

Studies have shown that all liquids - including liquid metal - flow in drops; that also applies to flowing into a square sprue.
Accordingly, the gas (air) contained in the cavity (casting mould) can escape freely across the unfilled corners.

Results:

  • No swirling of molten metal due to be back pressure of the residual air
  • Faster flowing in of the molten metal
  • More homogeneous castings
  • Smoother surfaces
  • Increased precision of fit
