The extrusion-blow molding of plastic pallets is similar to the blow molding method of general hollow products. Because the product is large and double-sided, it requires a larger extruder, mold clamping machine and mold. At present, China's hollow molding machine manufacturers have developed super-large hollow molding machines that specialize in high-speed production of high-strength blow-molded pallets. They are produced using HMWHDPE high-strength plastics, with fast molding speed, good product quality, high strength, high rigidity, and very long service life. The service life of a general blow-molded pallet can reach 5 to 10 years, and it can work stably in an environment of -40 to 40буC. The dynamic load of its products can reach more than 3t, and the bending strength reaches a high level. It is the preferred pallet for some pallets that require a long life and high-strength use environment. At present, its price is higher than other plastic pallets. Because its service life is particularly long, its cost performance is the highest among all pallets. This method will develop rapidly in recent years as the price of molding equipment is greatly reduced. It will have great advantages in saving limited oil resources and saving logistics costs.

Features of blow molded pallets

Raw materials:

High molecular weight and high density polyethylene (HMWHDPE) is used, which is superior to the various chemical and physical properties of ordinary low-pressure polyethylene (HDPE).

Suitable for the production of large hollow containers and can be used in harsh environments for a long time.

Production process:

Hollow extrusion and inflation are formed as a whole at one time, with uniform molecular weight distribution, reasonable load-bearing structure, and designed with sockets suitable for various forklifts.

Appearance:

Beautiful shape, no flash, no other auxiliary connections, no thorns, no debris, pure color, optional colors, neat structure, clean and hygienic.

Weight:

Light weight, good load-bearing performance, easy and safe to move in space, and no harm to people.

Carrying capacity

(evenly distributed) Net load 4-6 tons; dynamic load 2-3 tons; overhead load 0.7-1.2 tons.

Performance

a. Can be used in (-35бубл 40бу) environment, its performance remains unchanged;

b. Excellent impact resistance, no sparks due to friction, not easy to burn, no static electricity;

c. No rust, no water accumulation, moisture, water, washing resistance, easy to clean;

d. The service life is far longer than that of wooden pallets and injection-molded pallets, no maintenance required, resistant to falling and collision. Recyclable, in line with environmental protection requirements.

Service life

3-5 years under harsh environmental conditions; 7-9 years under normal environmental conditions.
