Taiwan pulp Molding Machines_Features_Why Direct-Hot-Press / Dry-In-Mold Technology?

2)Why Direct-Hot-Press / Dry-In-Mold Technology?

(1) TPM Series Direct-Hot-Press manufacturing process:
Slurry tank->Thermoforming Process->Thermoforming Process->Packing

(2) Conventional/Traditional Oven Dry manufacturing process:
Slurry tank->Forming/Molding Process->Transfer Process->Drying Process->After-Press/Molding Process->Packing

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:
-Completely dehydrate the molded pulp products inside of convex & concave moldings.
-No distortion and variation in shape & size.
-Smooth surface.
-Space efficiency.

Oven Dryer:
-Molded pulp is to be dehydrated by air circulation in the high temperature furnace.
-Distortion and variation in shape & size is inevitable.
-Rough and coarse surface.
-Large space occupation due to furnace conveyor belt.
