Metal Stamping Parts companies can use one or more production methods to complete mass production, including using the following methods:
Line dies: Line dies are tools that are loaded manually or automatically. Wire die is suitable for low-volume production or large awkward parts and can be placed in a single press.
Transfer molds: Transfer molds are technically a form of production line molds, but they are equally spaced and spaced in a press, and parts are moved by moving guides installed in the press.
Progressive die: The progressive die uses an automatic feed system to guide a metal strip through multiple die stations as the metal is unwound from the coil.
Mode of operation
Bend-The material deforms or bends in a straight line.
Flanging-The material bends along a curve.
Embossing-the material is stretched into shallow depressions. Mainly used to add decorative patterns.
Blanking-cutting a piece from a piece of material, usually a blank made for further processing.
Embossing-Compressing or squeezing a pattern into a material. Traditionally used to make coins.
Stretching-The surface area of the blank is stretched into other shapes by a controlled flow of material. See also deep image.
Stretching-The surface area of the billet increases due to tension, and the edges of the billet do not move inward. Usually used to make smooth body parts.
Ironing-Squeeze material along vertical walls and reduce thickness. For beverage cans and ammunition boxes.
Shrink / Neck-Used to gradually reduce the diameter of the open end of a container or tube.
Curl-Transforms the material into a tubular profile. Door hinges are a common example.
Hemming-Folds the edge onto itself to increase thickness. The edges of car doors are usually hemmed.
Punching and cutting can also be performed in a press. Progressive stamping is a combination of the above methods, which is performed continuously with a set of dies, and a set of materials passes through the dies at one step.
