Most specially designed screw and the advanced controlling system ensure excellent plasticization, high output and stable extruding. auto spiral screw feeding system. screw and barrel material is 38CrMoAla. complete line is fully automatic.
Mould of extruder
The mould uses high-quality alloy steel and throttling device to ensure even pressure of feed influent at the mould lips, and also differential action of up-down piece guarantee even thickness of the plate.
Cooling form mould plate
Vacuum system composes two independent subsystems and each is equipped with several fixed circulating vacuum lines of three-point type. Meanwhile, each line carries vacuum regulating system and vacuum display system that realize even and stable vacuum degree of plate surface.
Haul-off device
Configure two haul-off for whole line. first one is high power/ reduction ratio, multi-roller type, well low-speed operation, be able to draw the plate up from the calibrating table evenly and synchronous. The second is designed to remove stress, equip edge-cutting device to ensure the valid width and smooth cutting edges.
Depress oven
The oven removes the stress of hollow sheet, the heating oven is made by 304 stainless steel, equipped with separately temperature control system for each zone to ensure the heating to be uniform, 4 meter lengths for heating oven operation is necessary.
Wind cooling machine
Cooling improve the surface finish of plastic products, reduce the surface marks and internal stress of plastic products, keep the products from shrinking and deformation, accelerate product shaping, and improve the production efficiency of plastic molding machines.
Automatic cutter
After corona treatment, the cutting machine accurate instant length-fixed cutting and automatic up-down discharging system combined with alloy steel sharp blade to realize high-quality cutting. forward and backward is controlled by pneumatic.
Final product-hollow corrugated board
The pp hollow profile board has the features, light weight, high tenacity, damp proof, environmental performance and secondary processing. Instead of cartons paper with high recycling rate.
Production Flow Chart
Product Application
Application of PP Hollow Grid Boards The PP hollow grid board can be processed into turnover case, packaging case, clapboard, lining board, backing board and pallet etc. due to its advantages of light weight, high tenacity, damp proof, environmental performance and secondary processing. It is widely used in such fields as the electron, household electrical appliances, packaging, machinery, postal, food, pesticide and advertisement decoration, etc.
