Abstract
A formation device melts a plastic material and places the melted plastic material into a mold. The mold has an upper case, a lower case and a cavity, and a blowing aperture is disposed at a conjunction area of the upper and lower cases and extending to the cavity. The formation device utilizes a blowing tube to connect to the blowing aperture to reach into the plastic material in the cavity. During a blow molding process, the formation device inflates the plastic material through the blowing tube such that the plastic material expands to conform with a shape of the cavity, and when the mold is opened, a hollow casing member is obtained. The casing member further comprises a framed base, and two opposite sides of the base respectively connected to a top board and a bottom board via a connecting lip.
