heavy duty plastic pallet

What material tray is better? These three material production plastic tray, different performance advantages. When we develop procurement scheme, must according to own needs to choose, eliminate blind is recommended. Price is heavy duty plastic pallet not suitable, the same low price also may not be able to meet the demand of use. Rational analysis of the different tray performance, personalization procurement scheme, solve the use of customer demand, is has been unchanged corporate vision. At present, the domestic enterprise mainly adopts two ways injection molding, hollow blow molding production plastic tray. Plastic tray area is large, the quality is big, the projection area is between 0.8 ~ 8 m2, quality between 10 ~ 40 kg, thus generally need large clamping force, a large quantity of injection machine dedicated tray injection molding processing. Due to different structure forms and application scope, plastic tray molding method is also different in the actual production, mainly include: injection molding process, blow molding, gas assisted injection molding process, molding process and molding process, etc.
Imports of low density polyethylene this kind of material production of plastic pallets, plastic process generally use. Good toughness and resistance to acid and alkali ability. Rotomolding technology can produce special euro plastic pallet thick plastic tray, it has a high cost. So in general, use the material production of plastic tray, general tray to prevent leakage. The stability of plastic pallet material, and acid and alkali resistant requirements are very high.
According to the forming technique of parison is different, but also Divided into injection blow molding, extrusion blow molding and stretch blow plastic pallet box molding. When using this kind of molding process should pay attention to blow molding speed and the cooling time, otherwise it is easy to affect the mechanical properties of the finished product.
Blow molding process it simple shape, high stiffness requirement is for the production of plastic tray, bearing capacity of finished product, high impact strength, long life, but because of the molding cycle is long, high cost, low stackable plastic pallets productivity, large work volume on products processing, at the same time The technology leads to product all is double structure, cannot satisfy the use of some handling machinery. Suitable for HDPE masterbatch molding, it is with the aid of gas pressure in the closed in the mold heat parison hollow blowing into tray.
