Hollow blow molding and general hollow products blow molding method is similar to the use of HMWHDPE high-strength plastic production, fast molding speed, product quality, high strength, high stiffness, very long service life, the general service life of blow molded pallets can reach 5 ~ 10 years, while it can be in -40 ~ 40 ℃ environment stable work. The dynamic load of the product can reach more than 3t, and the bending strength has reached a high level. Is some need long life, high strength use of the environment of choice for the pallet, its current price is higher than other plastic pallets, because of its exceptionally long service life, so its cost-effective is the highest of all pallets. This method will gain rapid development in recent years as the price of molding equipment is reduced significantly. Will be for saving limited oil resources and save logistics costs have a greater advantage.
