Aluminum parts can be finished with liquid painting or powder coating. Although these two finishing processes provide a protective layer, each coating has its unique features, advantages, and limitations. These coatings contain pigments, additives, and resins. The main difference is that liquid painting contains a solvent whereas powder coating uses dry powder. Other differences include […]

Scaling in die casting simply refers to forming oxides on the metal alloy surface. The molten metal constituents react rather rapidly with the atmospheric oxygen to form oxides. It creates a scale layer on the exposed surfaces, leading to eventual disintegration.Scaling may seem somewhat similar to soldering as both defects derive from molten alloys’ sticking

Soldering refers to the random sticking of the molten metal alloy to the casting/tooling material. The molten metal of extremely high temperature forms a metallic compound upon coming into the tool’s contact. Thus, soldering occurs as some of the alloys become a part of the tooling. It’s a die-casting metal interaction defect known as die
