Due to the different structures and uses of the products, the solutions are also different. Our company's technical team formulates different solutions according to the products to be made by users; for example double-sided welded pallets are pallets for turnover and storage, which require good strength and strong bending resistance. In order to solve this problem, we have adopted a separate production order. face and then solder the solution. For this reason, we have developed a hot plate pallet welding machine to solve this problem. The stackable nine-leg pallet is a logistics turnover pallet. The difficulty is that it occupies a large space and increases the logistics cost. We design the pallet to be stackable, which greatly reduces the space and reduces the logistics cost.
