The thread of raw material is under great pressure, at the same time by the material barrel heating effect of raw materials, through the raw material compression, shear, friction between the barrel of the thread and the raw material, molecules and stirring action of friction, will produce a certain amount of heat. Therefore, the raw material in the barrel temperature gradually increased to its physical state will gradually change from the high elastic state of vitrification, and eventually become a viscous flow state, in order to achieve complete plasticizing. Because the screw has been rotating steadily, the plasticized uniform molten material is equal pressure, equal amount of extrusion from the molding mold mouth, into a certain shape of plastic products. After cooling finalize the design, that is, to complete the extrusion molding products.
High hardness, high finish, ultra low noise. PLC intelligent control, can realize the linkage between the main and auxiliary machines. Easy to monitor the man-machine interface, easy to understand the processing and machine status. The control mode (temperature controller) can be changed as required. Material is 38CrMoAL/A nitriding treatment, wear-resistant. Strict temperature control precision, air cooling water cooling combined cooling. Unique inlet design, with perfect water cooling device.
What is the choice of die for blow molding machine? By the mold size to determine the machine “large column distance”, “mold thickness”, “mold minimum size” and “die plate size” is appropriate, to confirm whether the mold can be placed. For example, the width and height of the mold should be less than or at least one side less than the large column spacing.
The width and height of the mold is best within the size range of the mold plate; The mold thickness of blow molding machine should be between the mold thickness of injection hollow blow molding machine; The width and height of the mold should conform to the minimum mold size recommended by the injection hollow blow molding machine, too small will not work. When the raw material is injected into the cavity at high pressure, there will be a force of mold support, so the locking unit of injection hollow blow molding machine must provide enough “locking force” to prevent the mold from being split. The calculation of the clamping force requirement is as follows: The projection area of the finished product in the direction of the switching die is calculated from the appearance size of the finished product; Support die force = projection area (cm2) of finished product in the direction of the switch die × mold hole number × mold pressure (kg/cm2).
The pressure in the mold varies with raw materials, generally 350-400kg/cm2 for raw materials; The clamping force of the machine should be greater than the clamping force of the die, and for the sake of safety, the clamping force of the machine should be more than 1.17 times the clamping force of the die.
