Score And Fold Sheet Metal

Many different tools cut sheet metal and each has its own strengths and weaknesses.

Score and fold sheet metal.

Typically the user creates a deep score and then gently taps the material to encourage it to snap in half. Place the fracture line over the edge of a table and bend the overhang slightly downwards. Scores can also be created in things like sheet metal making it easier to fold the metal into shape. While i was originally taught to use discs for catch building which involves only straight lines i discovered that they are superb for curved line scoring.

Finally bend the sheet up by hand to the angle desired. This weakens the aluminium and creates a fracture line. Scoring tools can also be used to cut glass quartz marble and other minerals. Place it on the sheet metal to be bent i use masking tape to keep it in position then press it into the sheet to the desired depth using a planishing hammer.

Next place the wood parallel and slightly behind the bending line. Watch the visual spread of the wire and keep it the same width in order to maintain an even depth of pressure. Silicon carbide separating discs are superb for scoring metal for bending particularly when the metal sheet is less than 4 or 5 cm across. If you want a sharp 90 bend tap along the crease with a mallet.

Flip the sheet over and repeat. International services we have invested in our machinery in order to provide a comprehensive range of metalwork services and produce highly sophisticated architectural metalwork. With the aid of a straight edge and a sharp knife score both sides of the aluminium sheet. His curved score folding technique has been recently recognised with two gold awards for technological innovation from the prestigious goldsmiths.

Sheet aluminium can be cut without the need for a guillotine or tin snips which tend to deform the metal. Most frequently expensive sheet metal bending tools called brakes are used to bend sheet metal but you can also complete this task without one. To score using a wire begin by bending it to the desired shape of the score. Therefore pvd sheet material is ideal for v grooving and folding as a cost effective alternative to brass bronze copper gold and iron.

Clamp the wood on top of the metal to the workbench. Bending sheet metal by hand is a manageable task if the piece of sheet metal is small and thin enough to handle.
