Apa itu Shrinkage in n Castinger?

Shrinkage exsus whens whee the metal cools and contraclits, leading to void or cavities within ia newin the.

Understanding Porosity

Porosity referes to tiny hole or voids with ia to e castil material, of ten cause by trapped gases or shrinkage.

Kalkulations for Shrinkage and Porosity

Kalkulations help predict potential defects and optimize casstg paremeters. For shrinkage, the volume change can be estimatech usting formula:

Pertama; FLT: 0 = 33; Volume shrinkape = Originall volume × Shrinkage persentape 1; FLT: 1; Aver3;

Porosity predition involves aniczinggas consut and solidification conditions, often requiring complex thermodynamic momik modymik mode.

Strategi Prevenon

Effective prevention of shrinkage and porosity includes profr gating decren, controlled cooling rates, and the use of feeders or risers to refsate for voeme contraction.
