Each thermoplastic material has a specific melting point, which is the temperature at which it transitions from a solid to a molten state. Heat fusion relies on raising the material's temperature above its melting point to achieve a proper fusion.
Heat is applied to the surfaces of the thermoplastic materials using various methods such as hot plates, heated tools, or specialized fusion equipment. The goal is to raise the temperature of the material to a precise range where it becomes molten but does not degrade.
