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, medicine, pesticide and advertisement decoration, etc.
Main machines of the production line:
Extruder: special venting type design, advanced PLC temperature control system to ensure that plastic sound and high-yield stability in plastics extrusion.
Screen Changer:optional hydraulic quick changer device, so that the process of changing network quickly and efficiently; duplex and special sealing structure, and ensuring stability for network devices.
Mould: mould made of high-quality alloy steel with high activity of the throttling device, so the distribution of material flow in the die pressure is uniform; the upper and lower lips of die is of differential regulation, ensures a uniform thickness from top to bottom.
Vacuum forming stand:forming system with a fast heat exchange cooling system, and with vacuum system, an effective staggered, sequential distribution to guarantee the accuracy of the sheet's shape. Vacuum system consists of two independent sub-structure, each subsystem equipped with a fixed number of three-loop vacuum lines, each carrying a fixed cycle of both the vacuum-conditioning system and vacuum display system, thus making the surface of vacuum plate uniform and stable .
