Acm Signage Material

3. Evacuating equipment: As PE particle itself contains water or may be exposed to water in transportation and as water will absorb enough
amount of heat in threaded rod extrusion process, if there is no vacuum evacuating equipment to boil off and to evacuate water, the water will
not get vaporized under high pressure inside the screw and will be extruded together with plastic. As a result that the pressure of extruded
plastic rapidly drops from high pressure inside the screw to normal pressure in air, water contained will immediately vaporize. At feeding
port of model and three rollers, vapor will pile up with water vapor continuously enteringto form larger bubble and then break up, which will leave many smallpits on trimmed core acm signage material surface. This will end up in failure of normal compounding.

4. Three rollers: Based on preset clearance among three rollers, grind, roll, cool and mold the molten plastic extruded out of forming
die to form acm signage material of certain thickness. Core panel surface shall be bright, flat without bubble and stripe. Panel thickness shall be uniform and in close tolerance.
