Wet pressing mold
The forming part with 2 difference process
one is “grout-in” the pulp and water run into the barrel then water be absorb by vacuums progress. It advantage is higher production output, because of staffs transfer to thermoforming need shorter time, disadvantage is need bigger draft angle, thin thickness, normally 0.8mm thickness, range 0.6~1.0mm thickness available.
Another forming we call it ”salvage” the pulp and water that is in the pulp pipe the forming mold is rising up, then desired shape finish. It advantage is smaller draft angle like 3degree,4 degree workable, good looking and high performance. what is more, thickness can reach 1.2mm which grout-in process hard to reach. disadvantage is slower capacity, after forming then transfer by special “car “ to the thermoforming step, but we have enough equipment to meet your production requirement, no problem. If you need high quality and cost supportable we suggest this one.
The forming mold can be aluminum material, also ABS possible, but hot pressing must aluminum, copper or steel, cannot ABS, because of high temperature about 200degree,ABS cannot meet that. The thermoforming step is the same, just forming little difference.
Dry pressing mold
The mold cost much cheaper than wet pressing mold, because of dry pressing no thermoforming mold and the mold material is recycled aluminum. After forming then transfer under the sun, if bad weather must in heat dry system to let the pulp drying, once pulp get dry using shape molding to press, the result is product with rough appearance, its advantage is products with thickness of 2.5mm or 3mm performance, drop testing may passed, so dry pressing molded pulp tray be often used in home appliance, corner protective, suitable for large and heavy products. Its advantage is stacked with big space, high warehousing and deliver cost, rough surface not high quality. One full set dry pressing mold including 1 set forming,1set shape press mold, some items with trimming mold.
