Annealing of molded ACRYPET product
So residual stress just after quick cooling still remains in a molded product that cracks may be formed in the paint process or at the contact with solvent. To prevent such crack forming, heat a molded product to the slightly lower temperature than the formable temperature to remove this residual stress.
