The stretched parts have no casting defects on the surface. The shape of the stretched parts should be simple and symmetrical, allowing for slight rebound at the mouth, and the side walls should permit a process slope. The wall thickness of the cylindrical section generally has a thicker top and a thinner bottom.

What is the difference between castings and stretchings, and how can you tell the difference from appearance?

Die castings are generally complex parts. The surface of die castings may include: stripes, cold shuts, scratches, depressions, bubbles, pores, shrinkage cavities, patterns, cracks, undercasting, marks, web-like burrs, and flash defects.

The surface of the stretched parts is free of casting defects. The shape of the deep-drawn parts should be simple and symmetrical, the mouth should allow slight springback, and the side walls should allow for process slopes. The wall thickness of the cylinder section generally has a thicker top and a thinner bottom.

Die-castings are components produced through the pressure die-casting process, involving a pressure die-casting machine with the mold loaded, which forces molten metals like copper, zinc, aluminum, or aluminum alloys into the machine's feed opening. After being pressed by the machine, they are cast into the mold's shape and form standard copper, zinc, aluminum, or aluminum alloy components. Such parts are commonly referred to as die-castings.

Die castings are known by various names locally, such as die cast parts, pressure castings, die castings, die cast aluminum, die cast zinc, die cast copper, copper die castings, zinc die castings, aluminum die castings, aluminum alloy die castings, and aluminum alloy die cast parts.
