How to start metal stamping? In order to kick off the metal stamping process, we always start with a proper design. This design is made by our engineers with the help of a tooling system. They make the design to a high precision so that with each punch the metal sheet gets bent in the most optimal way. Preparation is the most important step of the production process. Metal stamping is not hard, when the design is done correctly the fabrication process will follow. Hence the importance of the design up front. Rompa Group is lucky to have such great in-house engineers with many years of experience and with whom nothing is impossible. A single design can contain many intricate parts, so this first process can be complex and time-consuming. After this step is done we can start the manufacturing process.
Metal stamping starts with a flat metal sheet that is placed into the stamping press. This press consists of a tool and die surface that form the metal.
There are several types of metal stamping and forming techniques:
- Punching and blanking is a technique using a custom made die to cut the material. Punching is used, for example, to make holes in the sheet. It’s called blanking when we remove a workpiece from the sheets and the removed item is the desired piece.
- Another way of metal stamping is the bending technique. Think of shapes such as U or L Coining is the technique Rompa Group uses most, it allows us to place the workpiece between the press and custom made die.
- Embossing is used when we want a raised design from the metal sheet. Flanging is a stamping method to turn edges upright at a certain angle.
Production is made easy with the right tools! Our main tool for metal stamping is our follow-cut-bent stamp. This fully automated process bends and cuts the desired shape out of coils using 80 tons of pressure! Our tool can handle 250 cycles per minute depending on the design of the stamp. This fast production cycle is a perfect technique for large quantities with high accuracy. There are many different kinds of metal you can use for this process. For example, for electronic stamping various metals such as copper, copper alloys, steel, platinum, aluminum and gold can be used.
