The cooling channels to the mold surface placed as close as possible
but should pay attention to the mechanical strength of the mold material.
- Diameter cooling channels must be greater than 8 mm (8 or 10) for ease
of processing and must remain so to avoid the flow rate of the liquid
is cooled by different cooling diameter different channels.
- cooling system should be divided into several areas to avoid cooling
the cooling channels too long leads to disparities high temperature.
- pay particular attention to the cooling of the thickest part of the product.
- thermal conductivity of cast materials is also important.
- Note to the phenomenon of warping due to different shrinkage when surface
different product thickness.
