There are a number of large extrusions designed by Elson Designs. An extrusion is usually inexpensive tooling although the tolerances for the finished item can be quite large? First time I realised how large these tolerances were I was momentarily put off the process! However a competent tool maker with experience can make the finished item far better than extrusion tolerances would suggest. As a rule a toolmaker/extruder can achieve 2/3 the tolerance of that shown in EN755-9? Extract of EN755-9 For additional information feel free to discuss, please email info@elsondesigns.co.uk
