Plastic pallet extrusion-Hollow blow molding and general hollow products blow molding method is similar, because of its larger products, and double-sided type, the need for larger extruder, die-clamping machine and so on. At present, domestic hollow molding machine manufacturers have developed a professional high-speed production of high-strength blow molding tray of super large-scale hollow molding machine, the use of HMWHDPE high-strength plastic production, rapid prototyping, product quality, with high-strength, high stiffness, very long service life, general blow molding tray life can reach 5-10 years, At the same time can work stably in-40~40℃ environment. The dynamic load of the product can reach more than 3t, and the flexural strength reaches a higher level. It is the preferred pallet for long life and high strength use environment, at present its price is higher than other plastic pallets, because its service life is very long, so it's cost-effective is the highest of all trays. This method will be developed rapidly in recent years as the price of forming equipment is greatly reduced. Will have a great advantage in saving the limited oil resources and saving the logistics cost.
