We will anneal all acrylic products that require machining. This is because the material stress of the acrylic sheet increases during machining. Standard procedure for annealing Acrylic Products: Acrylic annealing only in a temperature-controlled convection oven The annealing temperature must be below the material-specific softening / melting point (80 ° C for cast acrylic) During annealing, the temperature must be kept as constant as possible and air circulation must be ensured on all sides within the furnace. A slow, steady increase in temperature and keeping the temperature constant over a comparatively long period of time. A very slow, even cooling is also decisive for the success of the annealing Annealing intervenes in the molecular structure of the acrylic: Molecular lattices that are "mixed up" during processing are reorganized, which releases the internal tensions. So that the acrylic retains these positive properties even after annealing, orderly cooling is important: The acrylic products should only be removed from the oven at below 50 ° C and then slowly continue to cool down at room temperature. Before further processing, all acrylic workpieces must therefore be tempered in order to free them from material tension.
