1. Injection molding method

Plastic injection pallets generally use polyethylene (PE) and polypropylene (PP). The texture is hard, chemically stable, non-toxic and tasteless, and will not cause any adverse effects on the product.

Injection molding plastic pallets are thermoplastic injection molding, that is, plastic materials are melted and then injected into the film cavity. Once the molten plastic enters the mold, it is cooled and shaped into a certain shape according to the mold cavity.

Due to the low cost of raw materials, it is currently widely used in China. The pallets produced by the injection molding process is smooth, flat, stiff and dense. Because of the mold production, the product design has greater freedom, and the appearance is beautiful, no flash, no thorns, no debris, pure color, color selection, and neat structure , Clean and sanitary.

The disadvantage of injection-molded pallets is that their bearing capacity is slightly smaller, with a net load of 1 to 10 tons, a dynamic load of 0.5 to 1.5 tons, and an overhead load of 0.3 to 1.2 tons. In addition, due to the production process, the tray structure is generally single-sided.

Injection plastic pallets are mainly used in three-dimensional warehouses, cold storage and other environments and logistics operations in various industries.

2. Blow molding method

The blow molding of plastic pallets is similar to the general blow molding method of hollow products. Because the products are larger and double-sided, larger extruders, clamping machines, and molds are required.

At present, domestic hollow molding machine manufacturers have developed a super large hollow molding machine that specializes in high-speed production of high-strength blow-molded pallets. It is produced by HMWHDPE high-density polyethylene, which has fast molding speed, good product quality, high strength and high rigidity. Compared with injection-molded pallets, it has greater bearing capacity, strong impact resistance, and longer life. Generally, the service life of blow-molded pallets can
