Manufacturing method of tray and tray

Abstract

The invention discloses a manufacturing method of the tray and a tray . The manufacturing method of the tray comprises the following steps: a, respectively preparing a bottom shell and an upper lid; b, positioning the bottom shell or the upper lid in a forming die of an electric power storage (EPS) foam make-up machine, and die assembling and filling EPS ball particles in a die cavity of the forming die; c, heating and enabling the EPS ball particles to foam and expand, forming an inner core which is connected with the bottom shell or the upper lid in a clinkering mode, and proceeding cooling processing; d, opening the forming die, positioning and combining the upper lid or the bottom shell on the bottom shell or the upper lid, and then die assembling, heating and enabling the EPS ball particles to foam and expand and to be connected with the upper lid or the bottom shell in a clinkering mode, and then proceeding cooling processing; e, demoulding and manufacturing the tray. The shell and the inner core of the tray possess good combination intensity, the condition that the shell and the inner core of the tray occur separation in the using process is effectively avoided, and so that the quality of the tray is guaranteed.

Description

technical field [0001] The invention relates to a transport container and its manufacturing method, in particular to a pallet manufacturing method and the pallet manufactured by the method. Background technique [0002] In order to move goods more efficiently, pallets are generally used to support goods, so as to facilitate the handling or loading and unloading of goods by forklifts. Traditional pallets are wooden pallets made of wood, which have disadvantages such as being susceptible to moisture, insects, and not being environmentally friendly, and are gradually replaced by plastic pallets. Common plastic trays are prepared by one-time injection molding of plastic materials. For example, the utility model patent No. ZL20052002995.6 authorized and announced by the State Intellectual Property Office on April 5, 2006 discloses a high-density polyethylene material. The plastic tray made of integral injection molding, the plastic tray made of this material has the defects of p...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is that the pallet manufactured by the existing pallet manufacturing method has the defect that the inner core and the outer shell are easily separated, so a method for manufacturing the pallet and the pallet are provided, and the pallet manufactured by the manufacturing method The inner core and the outer shell of the tray can be well combined and not easy to separate
