What type of repair involves using a mold to reshape damaged parts?

The type of repair that involves using a mold to reshape damaged parts is heat molding or hot-stretching. This method is particularly effective for thermoplastic materials, where controlled heating allows the technician to soften the material and then reshape it using a mold. By applying heat, the plastic becomes malleable, and once it is formed into the desired shape, it can maintain that shape as it cools down. This technique is useful in restoring the original appearance and structural integrity of plastic components without the need for replacement, making it a preferred method in non-structural repair scenarios.

Other common repair methods, like plastic welding or spot welding, focus on joining or fusing parts rather than reshaping them. Body filler application is used for surface imperfections but does not involve reshaping with a mold. Thus, heat molding accurately describes the repair process where a mold is utilized to reform damaged areas.
