Material Types for your Stamping Requirements
Lindy Manufacturing works with a wide range of materials in producing large number of different part numbers for our customers.
This is a partial list of Workable Material Types specific Stamping done at Lindy Manufacturing.
Bending is a common metalworking technique to process sheet. Usually bending has to overcome both tensile stresses as well as compressive stresses.
Blanking is cutting up a large sheet of stock into smaller pieces suitable for the next operation in stamping, such as drawing and forming. Often this is combined with piercing. Blanking is a shearing process where a punch and die are used to create a "blank" from sheet metal or a plate. The process and machinery used in a metal stamping company are usually the same as that used in piercing, except that the piece being punched out in the piercing process is scrap.
Coining is a form of precision stamping in which a work piece is subjected to a sufficiently high stress to induce plastic flow on the surface of the material. A beneficial feature is that in some metals, the plastic flow reduces surface grains size, work hardening the surface, while the material deeper in the part retains its toughness and ductility. The term comes from the initial use of the process: manufacturing of coins.
Drawing is a metalworking process which uses tensile forces to stretch metal. It is broken up into two types: sheet metal drawing and wire, bar, and tube drawing. The specific definition for sheet metal drawing is that it involves plastic deformation over a curved axis. For wire, bar, and, tube drawing the starting stock is drawn through a die to reduce its diameter and increase its length. Drawing is usually done at room temperature, thus classified a cold working process, however it may be performed at elevated temperatures to hot work large wires, rods or hollow sections in order to reduce forces.
Metalworking is the process of working with metals to create individual parts, assemblies, or large scale structures. The term covers a wide range of work from large ships, bridges and oil refineries to delicate jewelry. It therefore includes a correspondingly wide range of skills and the use of many different types of metalworking processes and their related tools.
Piercing is a shearing process where a punch and die are used to create a hole in sheet or a plate. The process and machinery are usually the same as that used in blanking, except that the piece being punched out is scrap in the piercing process. There are many specialized types of piercing: lancing, perforating, notching, nibbling, shaving, cutoff, and dinking.
Progressive stamping is a metalworking method that can encompass punching, coining, bending and several other ways of modifying metal raw material, combined with an automatic feeding system.
