A thermoformed shell is a plastic shell made using a thermoforming process. Thermoforming is a plastic processing technique that involves heating and softening a plastic sheet, then placing it in a mold, and using vacuum or pressure to adhere the plastic sheet to the mold surface. After cooling, the desired shape is formed.

Thermoformed shells are commonly used for packaging and protecting various products, such as electronics, toys, and cosmetics. Advantages include being lightweight, shockproof, waterproof, and wear-resistant, effectively protecting products from damage.

In making thermoformed shells, the mold must first be designed. Then, the plastic sheet is heated and softened, placed in the mold, and the plastic sheet is adhered to the mold surface using vacuum or pressure before cooling and shaping. Different materials, thicknesses, processes, and shapes can be chosen based on different needs.

It should be noted that the quality and performance of thermoformed shells are closely related to factors such as materials, processes, and molds. Therefore, when selecting and using thermoformed shells, reasonable selection and evaluation should be made based on product needs and requirements.
