There is a word called "professional", which is a good evaluation of the die-casting factory, and "speciality" is the premise of "professional". The specialized Dongguan zinc alloy die-casting factory may not be all professional, but the specialized Dongguan Zinc alloy die-casting factories must be professional. Generally, zinc die-casting parts usually have many holes, and these holes are often different. It contains many types, but can you correctly judge their type?

Sand holes include sand holes and slag holes. We usually call these two kinds of hole defects as sand holes. Sand holes are holes caused by falling sand. The shape is irregular and the holes The inner surface is rough and mostly located in a small position. The slag hole is the purity of the molten metal, which contains dross, which leads to poor slag retention during pouring, and then causes defects such as shallow depth, smooth inner surface of the hole and irregular shape. Shrinkage is caused by the shrinkage of the casting during the condensation process, which is irregular in shape, from top to bottom, and has large and small, commensurate triangular hole defects. Shrinkage is formed in the solidified area without the supplement of liquid metal or alloy. It usually appears at the hot joint of the casting wall and near the gate, and is often distributed under the concentrated shrinkage cavity.
