If your company is considering purchasing metal stamping parts, it is necessary to know some basic knowledge about it. For example, what kinds of metal stamped parts are there? What materials can be used to make metal stamping parts?
What are the basic types of metal stamping parts?
Metal stamping parts of the process and production process
What materials can be used for metal stamping?
Progressive die stamping. Progressive stamping is probably the most common metal stamping process. We use a single mold, gradually creating your custom parts as the strip passes through the mold. The part is carried by a strip and formed or formed at a plurality of stations in a progressive die. Progressive stamping parts are usually the most economical type of stamping. OBI and straight-edge presses range in size from 2 tons to 60 tons, specializing in precision stamping parts of various shapes and metals, precision stamping parts. These metals range in size from 0.002 to 0.250 inches thick and 0.060 to 4.00 inches wide.
Deep - stamping metal parts. We have Waterbury Farrel Cam corns presses and American Baird Transfer presses, sizes ranging from 5 to 45 tons, specializing in deep stamping of various banded metals. Materials include: stainless steel, brass, copper, nickel alloy and other metals to meet customer specifications. Our transfer machines or corns are used for deep drawing and can produce deep punching parts with separate punches and moulds. Deep drawing parts are metal stamping parts made of flat metal strips. A deeply drawn or perforated part that is deeper than its width is usually called a cup.
Sliding metal stamped parts. Multi-slide or four-slide metal stamping parts are usually the most complex parts with multiple bends or angles. These are wrapped or clamped parts. Multi-slider machines can also run multiple moulds at once and at different angles. This type of machine is also used to produce most of our wire forms. We have American Baird molding machines, from # 00 four sliders to # 35 more sliders, capable of making various wire and strip alloys into customized precision metal stamping parts. Our wire forming business now produces wire up to.125 inches in diameter.
Complex parts often require a series of different steps to create. Few parts that at first glance seem simple require only one stamping step to be considered correct.
Confusion is often found in determining the proper metal stamping process. When choosing metal stamping process, consideration should be given to:
How will the stamping process affect the design function
Design or industry specific requirements
Production time and cost effectiveness
Common metal stamping process
Blanking. If necessary, blanking is the first step in the stamping process. Blanking is the process of cutting larger metal plates or wires into smaller, more manageable parts. Blanking is usually done when drawing or forming stamping sheets.
Punching. If the part requires grooves, holes or other incisions, a perforation may be used. The perforation can be carried out simultaneously with the blanking, cutting out the necessary shapes from the metal plate.
To draw. Drawing is the actual stamping process of metal stamping. The punch forces a piece of metal through the mold, providing the main shape of the part. When the depth of the part is less than the main opening, it is considered shallow; Parts with a depth greater than the opening are deep drawn.
Bending. Bending is a fairly self-evident process. The part in progress is placed on a specially designed die, and a hammer pushes the metal to provide the required bending. Bend after stretching, because trying to press a sheet of metal that is already bent will deform the whole part.
Air bends. Air bending is the bending of a flat surface of a part into a usually v-shaped die by means of a punch. The space between the punch and die is greater than the thickness of the metal, resulting in a slight relaxation when the bending part is released. Air bending USES less power and pressure than other bending methods.
Backing and embossing. The bottom and embossing are bent in a process similar to air bending, but using a pressure of 2 to 30 times, the material is completely pressed into the compact mold, resulting in more permanent bending.
To shape. Forming is a bending process similar to bending, backing and stamping. It can create parts with multiple bends, such as u-bend, in one step.
Although there are thousands of metals that can be punched, they all fall into two basic categories - black and non-ferrous metals. Ferrous metals contain iron, nonferrous metals contain iron. Steel is a typical ferrous metal because it comes mainly from iron ore. However, aluminum does not contain iron and is a non-ferrous metal.
With the exception of a few exotic specialty metals, ferrous metals are magnetic and nonferrous metals are nonmagnetic. Because nonferrous metals do not contain iron, they are less likely to deteriorate due to oxidation or rust. Some of the non-ferrous metals commonly stamped are aluminum, brass, bronze, gold, silver, tin and copper.
Although metal stamping parts in life is very common, almost in all industries, but the metal stamping process is not simple.
