AcrylicFabWorks Compares Cold Bending, Line Bending and Thermoforming for Crack-Free Acrylic Parts
AcrylicFabWorks, the acrylic division of SinoPlastix, has published a process guide comparing cold bending, line bending and thermoforming for acrylic sheet, detailing the causes of cracks and crazing and the prevention methods.
Manufacturing & Process Note: Cold bending leaves residual stress that can cause crazing at fixings or when solvents contact the bend; annealing after forming is essential to relieve stress before bonding or cleaning. Line bending requires full-thickness heating to avoid cracking, and edge finishing before bending prevents crack initiation at notches.
