TPM Pulp Molding
Machinery
There are two types of Pulp Molding
Machinery:
1. Oven Dry manufacturing process:
Slurry tank > Forming/Molding Process>
Transfer Process > Drying Process > After-Press/Molding Process>
Packaging.
2. Thermoformed Process:
Direct-Hot-Press system allows low unit
cost manufacture of high precision Dry-In-Mold product in long
runs. Direct-Hot-Press technology has been used extensively for
the manufacture of cell-phone or electronic goods packaging.
Produced goods can be automatically stacked and only one
operator is required to operate (9) production lines with
Direct-Hot-Press systems (exclude necessary packaging
personnel).
Comparisons Between Oven Dry and
Thermoforming Manufacturing Process:
Thermoforming:
1. Completely dehydrate the molded pulp
products inside of the converse & concave moldings.
2. No distortion and variation in shape or size.
3. Smooth surface.
4. Space efficiency.
5. Suitable for product thickness (0.5mm -1.5mm).
The "other" oven dryer process:
1. Molded pulp is to be dehydrated by air
circulation in the high temperature furnace.
2. Distortion and variation in shape & size
is inevitable.
3. Rough and coarse surface.
4. Large space occupation due to furnace
conveyor belt.
5. Suitable for product thickness thicker
than 1.5mm.
6. Higher capacity output (shorter
production cycle time).
