There are two main types of plastic pallets: blow molding pallets and injection molding pallets.

1. Production process

The molding process of the blow molding tray adopts a relatively large hollow molding machine. During production, the HMWHDPE plastic is extruded into a tubular plastic parison, which is placed in the split mold while it is still hot, and immediately after the mold is closed, it is passed through the plastic parison. Compressed air is injected to make the plastic parison inflate and stick to the inner wall of the mold, and the mold is released after cooling and shaping;

The molding process for the injection tray is a large injection molding machine that melts the plastic material and injects it into the film cavity. Once the molten plastic enters the mold, it is cooled and shaped into a cavity-like shape.

2. Product structure

The surface of the blow molding tray is mostly flat structure and groove design, and there are single-sided and double-sided trays.

The appearance surface of the injection molding tray can be divided into flat, grid and other shapes, and the bottom has various structures such as Chuanzi, Tianzi, nine feet, etc. The product can be produced on one or both sides, which can meet the needs of customers in different industries, and has more flexibility. bigger.

3. Use environment

Different manufacturing processes determine different usage environments. Blow molding trays are mainly used in harsh environments and high-intensity operations; injection molding trays can be used in various environments and industries such as flat storage, three-dimensional storage, and cold storage, meeting the needs of different industries.

4. Production cost

The cost of blow-molded pallets on the market today is much higher than that of injection-molded pallets.
