Plastic can be shaped multiple times, but this depends on its type. Thermoplastics can be heated and reshaped repeatedly without significant degradation, while thermosetting plastics, once set, cannot be reshaped. Repeated heating and cooling of thermoplastics allow for recycling and reforming into new products, making them versatile in manufacturing processes. However, excessive reshaping may lead to material fatigue and loss of properties over time.
