Injection molding is a manufacturing process used to produce parts by injecting molten material into a mold.

• The material is melted in a heated barrel and then injected into a mold cavity.

• The mold is cooled and the part is ejected from the mold.

• Common materials used include thermoplastics, metals, and glass.

• The process is used to produce a wide range of products, from small parts to large automotive components.

Common defects in injection molding process include flash, sink marks, warping, and short shots.

• Flash: Excess material that escapes from the mold cavity and forms a thin layer on the parting line.

• Sink marks: Indentations or depressions on the surface of the molded part caused by uneven cooling or shrinkage.

• Warping: Distortion or bending of the molded part due to uneven cooling or internal stresses.

• Short shots: Incomple...read more

Sheet metal defects are imperfections that occur during the manufacturing process.

• Wrinkles or folds in the metal

• Cracks or splits in the metal

• Warped or distorted metal

• Incomplete cuts or perforations

• Scratches or dents on the surface

The type of molding raw material depends on the specific application and can include plastics, metals, ceramics, and composites.

• Plastics are commonly used for injection molding

• Metals are used for die casting

• Ceramics are used for slip casting

• Composites are used for compression molding

• The choice of material depends on factors such as strength, durability, and cost
