The joining of aluminium profiles at right angles (cut at 45°) for the manufacture of aluminium joinery – windows and doors – is usually carried out using screw-fixed corner joints. However, some manufacturers use a faster and, they claim, more efficient method: the crimping process. The corner crimping of aluminium profiles is carried out using a specialised machine known as a ‘crimping machine’, which uses compressed air to deform the aluminium profiles at the corner channels; It should be noted that these corner joints differ from the classic screw-fixed ones. Most aluminium profile crimping machines have the drawback of requiring dies for the head that pushes and secures the profiles; these dies must have a mirror image of the profile’s inner surface. However, equipment has recently become available that no longer requires jigs, as the alignment and clamping head is fitted with adjustable blades and can be adjusted to take the shape of the profile. Our company offers crimping machines from several manufacturers, which you can view below.
