Sources of Porosity in Die Casting

How to Control Porosity With Processing Parameters

The porosity of die cast parts is one of the primary concerns of buyers and designers. In die casting, porosity refers to the air pockets, small voids, or pores found within a metal part. Too much porosity in a part can be dangerous as it can compromise the structural integrity of the component. Porosity can

Hot Chamber Die Casting Method vs Cold Chamber Die Casting Method

Depending on the project, aluminium casting is carried out through a “hot” or “low” process. Diecasting is one of the most economical and fast molding processes. The advantage of this production process is that hundreds of thousands of castings can be produced relatively quickly using a single mold. All parts produced are of uniform quality

How to Avoid Die Casting Defects

Reference : https://diecasting.com/blog/how-to-avoid-die-casting-defects/ The production of die-castings includes a number of steps, any of which can result in a defective casting if not properly executed. Since repairing bad castings can be expensive, it’s important to avoid defect occurrences if possible. We’ll look at some common to areas of  die casting defects — including wall thickness
