Liedtke Kunststofftechnik GmbH uses the general tolerance DIN ISO 2768 "m" for non-dimensioned and not otherwise defined (length) dimensions. Due to the process engineering used, dimensions and tolerances are only permitted on the tool side. For nominal dimensions below 3 mm and over 2000 mm, corresponding tolerance specifications must be attached directly to the nominal dimension and require a separate check in advance on process reliability in series production.
