Injection molding produces plastic pallets that are flat, smooth, stiff, and dense, offering greater design freedom. These pallets are categorized into double-sided integral plastic pallets and double-sided assembled plastic pallets.
Double-sided integral pallets typically weigh over 15 kg per piece, have complex shapes, and require injection molding machines with a clamping force of at least 2500 tons. While these pallets are complex in design, require significant investment, and have higher costs, they offer higher production efficiency and better product quality due to fewer production steps. This method is not commonly used by general plastic processing plants.
Double-sided assembled pallets are produced by dividing the double-sided integral pallet into two parts, which are injection molded separately and then assembled. Although this product requires two sets of molds, the mold structure is significantly simplified, and the total mold investment is still cheaper than for integral pallets. The clamping force requirement is also reduced; a clamping force of ≥1500 tons is sufficient, which is easily achievable by most plastic processing plants. This production method is likely to become the mainstream in plastic pallet production.
