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
