Generally, large holes can be cast and small holes can be drilled out. So what is the minimum hole that can be cast? Can R12.5 and R15 be minted? The material is gray iron
Look at the situation, and some information is based on the production batch, and some are based on the thickness of the casting to determineThe minimum mass production of gray iron cast hole diameterMass production 12-15Mass production 15-30Single batch production 30-50The wall thickness is mm and the aperture is mm8-10, 6-1020-25, 10-1540-50, 15-3050-100, 35-50The above is for reference only. It depends on the actual situation, such as your casting method, casting material and so on.
Our company also has gray iron, not seen so small holeCasting should be no problem, with graphite core
