Core working principle 1. ‌Heating and softening‌ 2. ‌Servo driven positioning‌ 3. ‌Vacuum adsorption molding‌ 4. ‌Cooling and demoulding‌

The most common customer complaints about blister parts are "surface wrinkles" and "thin here and thick there": 1. Uneven heating 2. Insufficient vacuum or blocked pores 3. The pressing speed is too fast 4. The draft angle of the mold is not enough

1、 The basic core principle of plastic thermoforming is to heat the plastic sheet to a softened and plastic state, stretch and bond the mold with the help of air pressure, vacuum, and mold pressure, cool and shape it, and then cut the finished product. It belongs to the secondary forming process of thermoplastic plastics, and the raw materials are mostly PET, PP, PVC, PS sheets, which are mostly used for vacuum forming packaging boxes, trays, disposable lunch boxes, and plastic shells.
