Various sheet metalworking techniques
Would you like to have your metal part processed by using a specific sheet metalworking technique? Are you not sure which technique is appropriate for your application? Our skilled professionals will gladly advise you on the possible sheet metalworking techniques that your product requires:
1. Barrell tumbling or deburring
Certain metalworking techniques leave residues such as sharp edges or irregularities on the material, for example during laser cutting. We barrel tumble the metal to make rough or sharp edges smooth. By barrelling metal, which is also called deburring or tensile grinding, we make it clean, beautiful, smooth and hand-friendly, we maintain the correct shape and we avoid delays in further processing. We place your part between the grinding stones in a vibrating barrel tumbler. Water and a cleaning agent (compound) are added to this, so that dirt, shavings and chips are removed. The vibration creates friction between the grinding stones and your metal part, eliminating any imperfections.
We choose to shake the metal when rough deburring is required. We only place the parts in the drum, where they rub against each other and remove any burrs as a result of the vibration.
In some applications, a rough metal surface can cause problems. It is more susceptible to corrosion and dirt adhesion. In that case, we can polish your metal part. During this polishing process, we gradually use finer grits. The metal surface is given a high-gloss finish that minimises friction with other parts, increasing sliding power. In most cases, a polished finish is chosen for aesthetic reasons.
After welding or lasering long pieces, torsion may occur because of the generated heat. To make the metal flat again, we straighten it to be able to further process it.
Brushing or satin finishing is a sheet metalworking technique that we use to give your metal a matt/gloss line structure. This makes the material less susceptible to scratching and scratches become less visible. We also use brushing or satin finishing to remove damage and colour changes.
