Injection pressure and injection rate: injection pressurespecifications of injection molding machine is the material the highest pressure cylinder injection, rather than the maximumpressure of hydraulic system of injection, injection pressure and the relationship between oil pressure is inversely proportional to the screw cross-sectional area and the injection cylinder area ratio. There are three kinds of different screw can choose my company specifications injection molding machine with aclamping force, the minimum diameter of A screw, C screw,relatively speaking, the injection pressure with A screw can bereached for one of the largest.
The injection rate of molten material from the nozzle toemissions per unit time, the theoretical value is the product ofthe machine barrel cross-sectional area and speed. Therequirements of injection molding process of injection rate tends to not only numerical must be high, but also in the injection process of program design (i.e. grade injection). According to the specific characteristics of the use of plastic raw materialsand processing products, realize the effective control of the flow state of melt filling.
