                        What are the advantages and disadvantages of hollow blow tray?

(1) the advantages of hollow blow tray are as follows.

   Cash flow is low.The production of hollow blow molding tray with large extruded blow molding machine is multi-purpose, reducing investment cost, low mould cost and low investment.

   Jasmine is beautiful in appearance.According to the characteristics of product bearing capacity, the round columns and grooves in different directions are designed on the mould according to the mechanical principle, so that the product surface is equipped with anti-skid particles, and the product surface is smooth and has high dimensional precision due to the rapid cooling of frozen water.

   Phi performs well.The product is formed by extrusion blow and swell in one time, the forming process is fast, the material is blown and expanded rapidly in high melt state, cooling and finalizing, can eliminate the internal stress, make the product's internal quality and performance stable, meet the requirements of national standards.

   Superior security.Non-combustion-supporting, non-conductive, non-skid, no burr flying edge, no other auxiliary connection can ensure the safety of goods and operators.

   Kelvin has a long life.The product can increase the outdoor service life by adding anti-aging agent, and can be used for more than 5 years under general conditions.It can last 2 years in bad environment.The service life is 5~7 times of wooden pallet and 2 ~3 times of steel pallet.

   © environmental protection performance is good.The product is non-toxic and tasteless, resistant to the corrosion of acid and alkali salt, easy to clean and disinfect, not to rot, at the same time, the waste tray can be recycled and used, in line with the requirements of environmental protection.

   The cost of transportation is low.The quality of pallets is light, which can greatly reduce the cost of containerized goods transportation. When conducting foreign trade, it is not necessary for people to leave the country to be fumigated and disinfected by health and quarantine departments like wooden pallets.

   Low maintenance cost: plastic pallets do not need to be repaired or maintained, even if the exterior is damaged, as long as the inner pillar is well bonded, it will not affect normal use.

® adaptable.The hollow blow molding tray can operate in both directions and in four directions. It has two sides and one side. It can be used in all walks of life to improve working efficiency and space utilization.

   Higher capacity of repetition.Due to the reasonable structure design of the pallet according to the loading conditions, the loading capacity of the pallet is strong and the load capacity of uniform distribution is: static load 30-40kn, dynamic load 20-30kn, overhead load IOkN.

(2) the disadvantages of hollow blow tray are as follows.

   The processing procedure is complex.The post-processing process of hollow blow molding pallet is relatively complex, and the flying edges of each product (about 30% of the total weight of the parts) need to be repaired, while a large number of the flying edges need to be segmented and broken. After cooling for 24h, each product needs to be cut into forklifts with an electric saw.

   Parliamentary production efficiency is low.Although the production of hollow blow plastic pallet USES frozen water cooling, in order to improve product quality and productivity, but because the product has a large flying edge, the overall consumption of raw materials more, this requires the equipment to have enough high plasticizing capacity to shorten the molding cycle.The forming cycle of hollow blow molding tray is long, generally each cycle is 5-6min.The injection molding tray has a cycle of about 3min, which is relatively inefficient.

   Torque products have lower rigidity.Due to different molding methods, the rigidity of hollow blow molding pallet is not as good as that of injection pallet. Although the rigidity of products can be improved by adding reinforcing agent, filling reinforcing agent will speed up the wear of screw of equipment.
