What are the advantages and disadvantages of blow molding trays?

2022-05-04 Hits: 48 views

Plastic pallets are used to store bundled and wrapped goods, which are convenient for mechanical loading, unloading and transportation, so as to meet the requirements of loading, unloading, transportation and storage.

Today we are going to discuss the advantages and disadvantages of blow molding trays.

Advantages of blow molding trays

1. The investment of blow molding tray is less.

Using a large scale blow molding machine to produce a blow molding tray can achieve multiple uses in one machine, which cannot only reduce the investment cost, but also the mold cost is very low, reducing investment.

2. The appearance of the blow molding tray is beautiful.

According to the load bearing characteristics of the product, the designers started from the mechanical principle, designed grooves in different directions and circular columns with different arrangements on the mold, and provided anti-slip particles on the surface of the product. Due to the use of fast cooling frozen water, the product can be. The surface is flat and has high dimensional accuracy. There are reinforced columns in the product, which have high bearing strength and can adapt to various harsh environments.

3. The performance of the blow molding tray is excellent.

The product is formed by extrusion and inflation at one time, and the molding process is fast. The material is rapidly inflated and cooled in a high melting state, which can remove internal stress and stabilize the internal quality and performance of the product, which meets the requirements of national standards.

4. The safety of the blow molding tray is good.

Flame retardant, electric resistance, non-slip, no burr, no other auxiliary connections, and the product face and bottom have anti-slip designs to ensure the safety of goods and operators.

5. The blow molding tray has a long service life.

The product can prolong the outdoor service life by adding stabilizer. The service life of the blow molding pallet is 5-7 times that of wooden pallets and 2-3 times that of steel pallets.

6. The environmental protection performance of the blow molding tray is good.

The product is odorless, resistant to acid and alkali salt corrosion, easy to clean, and does not rot. At the same time, the waste pallet can be recycled, which meets the requirements of environmental protection.

7. The transportation cost of the blow molding tray is low.

The pallet is light in weight, which can greatly reduce the cost of containerized cargo transportation. When conducting foreign trade, there is no need for fumigation by the health and quarantine department like wooden pallets.

8. The maintenance cost of the blow molding tray is low.

Plastic pallets do not need repair and maintenance. Even if the exterior is damaged, as long as the internal columns are well bonded, it will not affect normal use.

9. The blow molding tray has strong adaptability.

The blow molding tray can be operated in two directions and four directions, and there are two types of double-sided and single-sided. It can be used in all walks of life to improve work efficiency and space utilization.

10. The bearing capacity of the blow molding tray is strong.

Due to the reasonable structural design of the pallet according to the stress conditions, the carrying capacity is enhanced and the carrying capacity can be evenly distributed. It has strong impact resistance, wears resistance and drop resistance, and has good resistance to violent operations.

Disadvantages of blow molding trays

1. The post-processing process of the blow molding tray is complicated.

The post-processing process of the blow molding tray is complicated. The flash of each product needs to be trimmed, and a large number of trimmed flashes must be divided and broken, and each product must be cut with a chainsaw after cooling for 24 hours. Cut the fork, and the leftovers will also be crushed.

2. The molding cycle of the blow molding tray is long, and the production efficiency is low.

Although chilled water cooling is used in the production of blow molding trays to improve product quality and productivity, the overall consumption of raw materials is large due to the large flash of the product, which requires the equipment to have a high enough plasticizing capacity to shorten the molding time cycle.

3. The product rigidity of the blow molding tray is low.

Due to different molding methods, the rigidity of the blow molding tray is not as good as that of the injection tray. Although the rigidity of the product can be changed by adding a reinforcing agent, the filling of the reinforcing agent will accelerate the wear of the equipment screw.

4. Products with blow molding trays are not suitable for manual hydraulic trucks.
