Sheet metal processing

Casting defects refer to imperfections, irregularities, or flaws that occur during the metal casting process, leading to substandard quality, compromised performance, or undesirable appearance of the final product. Casting defects are not only detrimental to the quality and safety of the final product but also pose significant challenges to the casting process. Beyond th...

The majority of casting defects fall into six main categories: gas porosity, shrinkage defects, metallurgical issues, problems with pouring metal, mold material flaws, and shape imperfections. 1.Gas Porosity: Gas porosity defects occur when gas is trapped within the casting during solidification, resulting in voids or bubbles in the metal. These defects can weaken the c...

Sinker EDM, which stands for Sinker Electric Discharge Machining, is a non-traditional machining process that uses electric discharge to shape conductive workpieces. This is like using a controlled electric spark to carve metal, where the shape of the electrode is accurately replicated onto the workpiece, creating the desired three-dimensional structure. (1) In an elect...
