What Are The Advantages And Disadvantages Of Injection Moulding? Plastic injection moulding advantages centre around great precision and high repeatability, combined with speed, a low cost per part and a huge choice of available plastics. Disadvantages include a higher initial cost and lead time than some other processes. What is an disadvantage of injection moulding?
What Is Mold Constant? The mold constant B depends on the properties of the metal, such as density, heat capacity, heat of fusion and superheat, and the mold, such as initial temperature, density, thermal conductivity, heat capacity and wall thickness. The S.I. units of the mold constant B are s/m2. What is N in Chvorinov’s

What Is The Purpose Of Binder In Sand Casting? It may also include an organic binder such as phenolic resin to increase its adhesion to the first layer. The purpose of a core binder is to provide strength to a core and hold the sand grains together. Hence, binders prevent the core from falling apart.
