metal stamping can be automated
Metal Stamping is a process of laying flat sheet metal into either blank or die cut to form into a mold in which a die is used to stamp a particular shaped area on the metal. The metal will be heated and pressed to make it into the mold which will hold the shape of the pattern which has been pre-programmed. Stamped metal is typically pressed from the rear (injection) side of the press unlike metal sheeting which is pressed from the front (outlet) side. The process of metal stamping can be automated using a CNC milling machine, but often an individual will opt to create their own stamping dies to produce intricate designs.
Metal Stamping is a complex process that takes practice and expertise. You must have a firm foundation in the fundamentals of sheet metal bending and sheet metal casting so you can work accurately with the equipment you are using and achieve the best results possible. Metal Stamping is a very popular method for producing metal products by many manufacturers today. This process uses tools such as punches, presses, die grinders, metal stamping machines, and drill presses to apply the metal into both blank and die forms. Metal Stamping is a simple metal shaping process that is used to create various metal products such as letter boxes, bottles, cans, panels, tubing, wires, fasteners, lockets, and badges.
sheet metal application and sheet metal bending
Metal Stamping requires precise and detailed mathematical designs to get the final product you desire. Metal stamping involves accurately measuring the dimensions of the part you want to create as well as precise measurements of the material you are working with and precisely creating the required design. Metal stamping products require precision cutting, drilling, tapping, bending, and bonding procedures to get a finished product that is functional and accurate.
The process of Metal Stamping has two basic parts; sheet metal application and sheet metal bending. Sheet metal bending is a process where the metal is heated in a bending machine and the bend is applied with a machine that applies a constant pressure onto the metal until it is able to withstand the pressure. This type of bending is not the normal rolling of a hot rolled edge or pressing of a flat sheet of metal, but rather a process where the metal is bent into its specific shapes. This is one of the most common types of metal bending and is often referred to as coining.
distortion of the stamping and will affect the overall quality
There are many different kinds of coining operations such as: cupping, which are similar to cupping but require a very specific temperature range; bending, which uses rolling efforts to produce a die imprint; and piercing, which involves the use of a hand ram tool to impinge metal into its targeted areas. The flat sheet metal piercing process creates a very clean seam that is very difficult to deform or leave jagged. In order to avoid this problem it is important to apply a high tolerance heat resistant coating to the workpiece after the piercing operation. This will help to protect the metal from any damage. Another common problem is migration, which occurs when the workpiece moves across the die and causes some of the metal to be pushed into the blank between the workpiece and the adjacent die. This can cause distortion of the stamping and will affect the overall quality of the stamping.
Many tools are used to perform the coining and bending processes and include: metal presses, metal rollers, die presses, stamping machines, air-bends and die benders. Air benders are used to inflate the sheet metal without impeding the flow of gas and as the die cools, the air is expelled leaving a neat, clean and precise imprint. As you can see, metal stamping is a complex process. In order to get the best product, you must use the best tools and operate your machinery correctly to get the most accurate and consistent results.
