Abstract

PURPOSE: To obtain molded products of desired forms with simple and short process, having excellent form stability, by heating a side of thermoplastic resin sheet locally, holding the sheet with the heated surface inwardly, and by inducing deformation by free bending without applying external force.
CONSTITUTION: Molded products of desired forms are obtained thru the process of heating a side of thermoplastic resin sheet (e.g. polyethylene, polypropylene, etc.) locally, and causing deformation by free bending whthout applying external force. It is preferable that the heating temp. be set at above the softening point but between the melting and the decomposition points, and the desired bent angle of the sheet is available in accordance with the heating temp. (i.e. electric current value) and the heating time.
