In the field of plastic pallets, injection molding and blow molding processes are the two mainstream technologies, and their core differences stem from the molding principles and material characteristics. The injection tray adopts high-pressure injection technology, where molten plastic is injected into the mold and cooled to form a solid structure. The product surface can be designed as a flat or grid shape, and the bottom supports various structures such as Sichuan and Tian characters. It can be flexibly adapted for single-sided or double-sided production. The blow molded tray is formed by hollow blow molding, which causes the plastic to expand inside the mold to form a hollow body, leaving blow molding holes on the surface. It can only produce double-sided trays, and the fork direction is usually two directions. This structural difference directly leads to a lighter weight and lower transportation cost for blow molded pallets, but injection molded pallets have more advantages in structural diversity and customization flexibility.
In terms of performance, injection molded pallets are known for their high strength and precision, and their tight structure endows them with excellent load-bearing capacity, making them particularly suitable for automated warehousing systems, ensuring stable coordination with mechanical equipment. In addition, injection molded pallets are corrosion-resistant, easy to clean, and can be used for a long time in complex environments such as flat warehouses, three-dimensional warehouses, and cold storage. Blow molded trays, on the other hand, have outstanding impact resistance and low temperature resistance due to their hollow design. They can withstand high-intensity operations and harsh environments, but their load-bearing capacity is relatively limited. For example, in high or low temperature scenarios in the chemical industry, blow molded trays are more favored due to material stability.
The balance between economy and environmental friendliness is the core of market competition between the two. Although the initial mold cost of injection molded pallets is relatively high, large-scale production can significantly reduce single piece costs. Its long lifespan and recyclability make it a model of circular economy, especially suitable for high-frequency industries such as food and beverage, logistics, etc. Blow molded pallets, with their lightweight design, reduce transportation energy consumption, making them more cost-effective for one-time or short-term use in fast-moving industries such as e-commerce and express delivery.
In terms of application fields, injection molded pallets dominate the market with wide adaptability, covering multiple industries such as food and beverage, medicine, logistics, etc., especially suitable for scenarios with high requirements for load-bearing and precision, such as precision instrument transportation. Blow molded pallets focus on special environments such as chemical and high-intensity operations, and their lightweight design is suitable for one-time or frequent handling scenarios. Overall, injection molded trays have become the mainstream choice due to their cost-effectiveness and versatility, while blow molded trays occupy a place in specific fields due to their impact resistance and low temperature resistance.
