Detailed Description

The invention is further described below with reference to the accompanying drawings.

As shown in fig. 1, a pallet capable of carrying more than 1.5 tons of goods is characterized in that: comprises a panel 1 and a bottom plate 2 which are integrally formed by injection molding. The temperature of the injection molding process is 230-250 ℃, the injection molding pressure is 20-30MPa, and the pressure maintaining pressure is 5-10 MPa. The material of the panel 1 and the bottom plate 2 is impact polypropylene material with melt index of 2.0-8.0, the impact polypropylene material is block copolymer of propylene and ethylene, the weight ratio content of ethylene is 4-5%, and the density of the impact polypropylene material is 0.89500-0.910g/cm³In the meantime.

As shown in fig. 2, the panel 1 comprises a deck 12 and three parallel first girders 11 located below the deck 12. A plurality of first grooves are densely distributed at the bottom of the plate surface 12 between the adjacent first girders 11, and connecting ribs between the adjacent first grooves are mutually connected into a grid-shaped first rib body 13. A plurality of through holes 14 with the diameter of 4-6mm are formed in the plate surface 12 between the adjacent first girders 11.
