Manufacturing Impacts of Scratching
Sheet metal scratches provide a costly and unwanted issues during your manufacturing process.
Scratches increase wastage and the time it takes to get a product to market.
Sheet Metal scratches also incur additional costs that may not have been budgeted for. Costs and inconveniences increase exponentially the further into the process that they are discovered, so it’s important to take the necessary steps to prevent scratching. Doing so will reduce disruption and even increase productivity.
Different processes are vulnerable to different types of scratching, depending on the process being undertaken. It’s vital to be able to identify and resolve problems. Today, we’re invesitgating how to reduce and eliminate them.
Friction scratching occasionally occurs during metal fabrication, particularly when there is formation of a built-up edge. A built-up edge is created when working with metals such as low carbon steel, stainless steel or aluminium. The plate gets damaged and, as a result, causes friction scratches as it’s dragged across the mould.
To avoid friction scratching, you should regularly clean the sheet metal you’re working with and the worktable. You should be ensuring there is no debris, which will prevent the problem from happening to you. Additionally, try lowering the punch speed to reduce the risk of built-up edge.
When bending metal, abrasion marks and scratches can be caused by the punch as it moves across the surface. One solution to this is to use a die-covering material strip. This should be laid over the top of the die to separate the part from the machine during the bending process.
Additionally, there are many forms of anti-scratch mould available which can help reduce the risks or marking significantly, and help you avoid issues associated with sheet metal scratching.
