Features of air slip vacuum forming

This is a method of vacuum forming where a sheet of thermoplastic resin, softened by heating, is free-blown, and after pushing up a convex mold, the air between the mold and the sheet is expelled to perform vacuum forming.
【Features】
1. It allows for deeper forming compared to trade vacuum forming.
2. Since the convex mold is inserted into the inner part shaped like a hemisphere, the corners of the mold do not strongly contact the sheet, resulting in fewer drag lines.
3. When free-blowing, the hemispherical ceiling part is well stretched, and when it is vacuum-adsorbed to the mold, the side wall part is also stretched, resulting in relatively less uneven thickness.
4. The strength of the formed product increases as it is stretched in two axial directions.
