Process flow for PP PC hollow sheet extrusion production line
Raw material + additive → mixing → vacuum feeding machine → hopper dryer → single screw extruder → color code extruder (depend on instrusion of the sheet)→Hydraulic screen change(optional) →melt pump → T-die →Vacuum calibrator forming machine →First hause off unit →Anneal oven →Cooling bracket →Double side Corona treatment device(optional)→Second haul off unit →Cross cutter and transmission unit→Collect table
PP Hollow Machine Introductin
PP Hollow Corrugated Packing Sheet Extrusion Making Machine can produce the sheet with the width of 1000-2800mm.We can provide all auxiliary machine for plastic pp hollow sheet to make box,suas as the edge sealing machine,die cutting machine,printing machine,welding machine etc.
Processing for making PP packing box:
PP hollow sheet turnover box main material is a PP hollow sheet, and then after the pressure cut, torn edges, stitching, assembly and made of a series of processing flow.
Below is the example of processing for turnover box
1, the extrusion line produce the required PP hollow sheets with required width and thickness, and cut into required length. And collecting different sizes in different stacking.
2,Use the pressure cutting machine to cut the PP hollow sheet into required shape. Pressing action should be accurate, rapid,agile, and keep the board clean, in accordance with the provisions of a unified placed on the table.
3, the professional workers tear the extra edges according to the indentation from the pressure cutting machine, The tearing action should pay attention to the intensity. to ensure the board neat appearance, it is not allowed to produce flash and laceration because of strong tearing force.
4, stitching the two sheets by rivets, flat wire or welding, etc., the stitching seal can be sealed by fiber tape or glue or magic paste.
