There are still a lot of pallets in our surroundings, but ordinary pallets have a weaker load-bearing capacity and are not strong enough. Industrial tray molding is not the same. It can bear more gravity and a larger area.

The dimension of the pallet product in the thickness direction is much smaller than the dimensions in the other two directions, and the physical quantities such as temperature vary greatly in the thickness direction. If the simple finite element or finite difference method is used, the analysis time will be too long, which cannot meet the requirements of mold design and manufacturing. Actual needs. We use the finite element method in the flow plane and the finite difference method in the thickness direction to establish grids that are compatible with the dimensions of the flow plane and the thickness direction and perform coupling solutions, so that the calculation speed meets the needs of the project under the premise of ensuring the calculation accuracy. The control volume method is used to solve the problem of moving boundaries informing. For products with different internal and external corresponding surfaces, they can be divided into two parts of the volume, and each form a control equation, and the coordination of the two parts is ensured by interpolation and comparison at the junction.

No matter how the technology of industrial tray molding changes, its main purpose is to make the quality of the finished product better.
