Mold preparation |
prepare the tray mold suitable for thermoforming. The mold design should match the desired tray shape and size.
|
Material preparation |
Select white PP plastic sheet material that meets the requirements. The sheet should have the appropriate flexibility and heat resistance for thermoforming.
|
Heating and softening |
Place the sheet material in the thermoforming machine and heat it to soften. Thermoforming machines typically have top and bottom heating devices to ensure even heating and softening of the entire sheet.
|
Forming and vacuuming |
The softened sheet material is placed over the mold in the thermoforming machine and is vacuumed onto the surface of the mold. By increasing external pressure or utilizing negative pressure, the sheet material is firmly attached to the mold and formed according to its shape
|
Cooling and solidification |
During thermoforming, the mold's temperature is reduced through a cooling system, allowing the plastic to cool and solidify quickly. This helps maintain the tray's shape and stability.
|
Demolding and trimming | After cooling, the formed white tofu PP tray is removed from the mold. Trimming is then performed to remove any excess flash or uneven edges. |
