Crystalline plastic bucket on a number of factors that influence the injection molding machine, we all know that plastic injection molding machine barrel production process is very important. In plastic barrels of production processes in the process, the crystalline plastic injection molding machine barrel will have a lot of factors, let's do some presentation on its main elements:

    Need to enter a) a crystalline melting plastic large energy is required to destroy the crystal lattice, so transformed from a solid to a molten melt more calories, plasticating larger capacity injection molding machine, but also the corresponding maximum injection improve.

    2) the crystalline melting point of the plastic range is narrow, in order to prevent the nozzle when the crystallization temperature is lowered rubber clog the nozzle, the nozzle aperture should be appropriately increased, and the installation of the nozzle temperature can be individually controlled heating circle.

    3) As the mold temperature has an important influence on the degree of crystallinity, so the mold as much water should ensure the molding mold temperature uniformity.

    4) there is a greater crystallinity of volumetric shrinkage during the crystallization process, causing larger mold shrinkage, and therefore in the mold design to seriously consider its mold shrinkage

    5) Due to significant anisotropy, internal stress, in the mold design should pay attention to the location and size of the gate and the location and size of the ribs, or prone to warpage, and then rely on the molding process is very difficult to improve .

    6) the degree of crystallinity and a plastic tub wall thickness related to the thickness slow cooling high crystallinity, large shrinkage, prone to shrinkage, porosity, so pay attention to controlling mold design plastic wall thickness control
