Factors Affecting The Metamorphic Layer Of The Middle Wire Cutting 1. Metallographic structure and elemental composition of the workpiece material Due to the discharge of the electric spark, the metallographic structure of the surface layer of the workpiece material changes significantly, forming a discontinuous, uneven thickness of the metamorphic layer. It is related to the…
What Is Vacuum Casting? Vacuum casting is a process that uses a ventilated mold. The molten metal flows into the mold by air pressure and then removes the air to form a vacuum. This casting method is mainly used for small parts or jewelry with intricate details. It is a physical modeling method. The vacuum…
What Kinds Of Vacuum Casting Are There? Vacuum casting can be roughly divided into three types: vacuum suction casting, vacuum low pressure casting, and vacuum differential pressure casting. 1.Vacuum suction casting Vacuum suction molding refers to placing the mold in a closed container and extracting the air inside the mold to cause a certain negative…
