Description

Metal pallets that can be easily processed and fabricated and manufacturing methods thereof

The present invention relates to a pallet for handling, storing, or transporting a material and a package, and more particularly, to a pallet for improving durability and weight, a non-ferrous metal or a non-ferrous metal of aluminum or its alloy material having a specific gravity less than iron. The present invention relates to a metal pallet and a method for manufacturing the same, which are easily formed and processed so as to have an economical efficiency by improving productivity by making processing and assembly easy.

Pallet refers to pallets with constant width and length. Pallets are piled up to a certain size on pallet so that cargo can be of a certain size to improve the efficiency of loading and unloading. Standardization is a method.

In other words, pallets are widely used for assembling, storing, laminating, handling and transporting goods as unit loads, and are mainly made of wood, metal or plastic.

In general, wood pallets using wood are most commonly used. Recently, however, wood pallets have continued to attract attention by environmentalists and various government agencies due to deforestation issues, environmental issues due to waste wood disposal at landfills, and import and export of products with wood parasites between countries and continents. I am getting it. As a result, many countries have applied many regulations regarding the use of hard wood packaging materials, such as the International Standard for Phytosanitary Measurements (ISPM 15) of the World Health Organization (WHO).

Due to the above reasons, wood pallets have recently been proposed to replace wood pallets by plastic and metal pallets, but plastic and metal pallets are only minimal for wood pellets due to high manufacturing and production costs. It is being used.

Moreover, plastic pallets have the problem of having a fatal adverse effect on the environment during manufacture and disposal.

Therefore, metal pallets should be used in place of pallets of wood and plastic products. However, metal pallets have good durability, but have a higher weight than other pallets, and have a disadvantage in that the price increases due to a number of processes involved in manufacturing a low weight to solve this problem.

As with the accompanying patent documents, various techniques regarding the pallet are provided.
