The materials for producing plastic pallets are generally PE and PP. Relatively speaking, the performance of pallets produced by PE materials is better than that of PP materials. The plastic tray produced by PE material is worse than the PP material in cold resistance. As the saying goes, there are advantages and disadvantages. In the high temperature resistance, the PE material is not as good as the tray produced by the PP material. If the plastic tray is used in a high temperature environment, the tray produced by the PE material cannot be selected. Although the plastic tray produced by PP material has certain advantages in high temperature resistance, it is inferior to PE material in low temperature resistance. For example, if the plastic tray is used in a cold storage, the tray produced by PP material cannot be selected. Therefore, when selecting the plastic pallet material, the customer should choose according to the local climatic conditions and the use environment. Generally, the temperature in the south of China is higher, and the plastic pallets produced by PP materials are more popular, while the temperature in northern China is lower, especially in winter. The low temperature in the northern region has reached about 30 °C, and it is necessary to choose the plastic tray produced by PE material.
We carry out the 3D modeling data of the pallet mould according to the pallet product data provided by the customer. After the 3D modeling data of the pallet mould is made, the pallet mould steel is ordered, and the selection of the mould steel is such a requirement for the structure. The structure of the tray mold requires high hardness. Therefore, the selection of the material of the tray mold is very important. Generally, the pre-hardened acid-proof steel such as 2316 and M340 can be selected. The performance of the two materials is super corrosion-resistant, the polishing performance is good, and the lens is easy to reach. Polishing effect, the hardness after quenching can reach more than 52, and the wear resistance is quite strong. The spare parts of the spare parts, guide posts, guide sleeves, sliders, slider sleeves, inclined top blocks, etc. are made of wear-resistant standard parts to improve the service life of the tray mold. The surface of the tray mold is mirror polished.
After the 3D data of the modeling tray mold is good, after the steel is also selected, the CNC machining of the tray mold starts, and the person in charge of the tray mold arranges the processing flow of the mold. After all the processing of the tray mold is completed, it starts after the start. The transfer of the pallet mold is also the most important step. After the completion of these steps, the test of the pallet mold can be carried out. After the product is qualified, the final completion of the pallet mold can be confirmed with the customer.
