1. Oven Dry manufacturing process : |
Slurry tank->Forming/Molding Process->Transfer Process->Drying Process->After-Press/Molding Process->Packing
|
|
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 packing personnel). |
| Comparisons Between Oven Dry and Thermoforming Manufacturing Process: |
| |
| Thermoforming: |
| 1) |
Completely dehydrate the molded pulp products inside of convex & concave moldings. |
| 2) |
No distortion and variation in shape & size. |
| 3) |
Smooth surface. |
| 4) |
Space efficiency. |
| 5) |
Suitable for product thickness (0.5mm~1.5mm) . |

| Oven Dryer: |
| 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 capcity output (shorter production cycle time.) |
