Vacuum forming method

The invention discloses a vacuum forming method. The vacuum forming method comprises the following steps that a thermoplastic resin material is used as a base material, a high-resistance inorganic material with an anti-static function is doped into the base material, a lubricating material with a lubricating function is added into the base material to obtain a vacuum forming material, and vacuum forming is carried out by using the vacuum forming material. The high-resistance inorganic material is added into the base material, so that the vacuum forming material has the anti-static function, and the texture homogeneity and the physical property of the vacuum forming material can be affected by adding of the high-resistance inorganic material, so that the lubricating material with the lubricating function is further added into the base material; and the lubricating material enables the vacuum forming material to have good fluidity during vacuum forming, has good followability to a mold, can reproduce details of
