A casting defect is an undesired irregularity in a metal casting process. Some defects can be tolerated while others can be repaired, otherwise they must be eliminated. They are broken down into five main categories: gas porosity, shrinkage defects, mould material defects, pouring metal defects, and metallurgical defects.

A bronze casting showing the sprue and risers. A riser, also known as a feeder, [1] is a reservoir built into a metal casting mold to prevent cavities due to shrinkage.Most metals are less dense as a liquid than as a solid so castings shrink upon cooling, which can leave a void at the last point to solidify.

West Bend Company; Wonder Pot – an Israeli invention for baking on top of a gas stove rather than in an oven. It consists of three parts: an aluminium pot ...
Additionally, the range of axial orientations in the directional solidification starting block should be minimized in order to successfully grow a single crystal. [12] This is difficult depending on the range of orientations in the DS starter block, and therefore makes orientation control a large area of focus.
This practice can also be observed in some cold-box coremaking practices, though cold box shell-core making is much less common. In a similar vein, the cold-box process uses a binder that is hardened through the use of special gases. The binder coated sand is packed into a core box and then sealed so that a curing gas can be introduced.

Air entered the bottom of the box and was heated both by the fire and by the fumes flowing over the front and back of ...
