Bending and Forming of Plastics
Dynalab Corp custom plastic fabrication department machines products for use in laboratories, industry, education and even the home. Bending and forming plastics is a very common procedure in our plastic fabrication shop. As shown in the photo at right, Polycarbonate is a unique material in that it can undergo a process called "cold bending". A sheet of polycarbonate is being bent to a 45° angle in a Press Break.
Certain plastics have a tendency to waver on the bend. A good way to avoid this is to score the plastic lightly before bending... forcing the bend to follow the straight score.
