Vacuum thermoforming is a plastic processing technology that combines multiple steps such as heating, vacuum adsorption, and cooling shaping. In the process, the plastic sheet is first heated to near the softening point, and then placed above the mold. Next, the air between the mold and the sheet is extracted by a vacuum pump to make the sheet tightly adhere to the surface of the mold. Finally, after cooling and shaping, the sheet solidifies into the desired shape of the product. This process is widely used in multiple industries due to its high efficiency, flexibility, and low cost.
2、 Characteristics
