Relatively speaking, the production process tends to be mature and stable; injection molding trays have been developed in China for four to five years and have just started. Therefore, in the production technology and manufacturing process There is still room for further improvement. Production equipment The injection tray is molded by a large injection molding machine at one time, and the product is strong and durable. The blow molding tray is hollow blow molded by a blow molding machine, but there are more blanks in the manufacturing process; in terms of the manufacturing time of a single product, the injection molding tray takes a shorter time. product structure There are blow molding holes on the surface of the blow molding tray, and the middle is completely empty. Only double-sided trays can be produced, and single-sided trays cannot be produced, and the product entry direction is generally two-way entry. The appearance surface of the injection tray can be divided into two types: Shapes such as flat plates and grids, and various structures at the bottom, such as Chuanzi, Tianzi, Qijiao, Jiujiao, etc. The products can be produced on one side or both sides, which can meet the needs of customers in different industries. More flexibility. use environment The different manufacturing processes of the two pallets directly affect the environment in which the pallets are used. Generally speaking, blow molding trays are mainly used in harsh environments and high-intensity operations, while injection molding trays can be used in flat warehouses, three-dimensional warehouses, cold storage and other environments and industries, meeting the needs of different industries. Cost of production At present, the cost of blow molded trays in the market is much higher than that of injection molded trays. Industrial DistributionBlow-molded tray products are mainly used in the chemical industry; injection-molded trays are used in food and beverage, chemical, pharmaceutical, logistics and other industries, and are more widely used in industries than blow-molded trays.
