What is Vacuum Molding?

After heating thermoplastic material close to the softening point, contact it to the mold and depressurize at the lower part of the mold at the same time. Then, the air in the space between the sheet and the mold is let out of there, and a vacuum is created, so the one that has the same shape of the mold is made.

(The industrialization began in Japan in 1955)
