Precision injection molding technology "precision" of the.

 

With the "3C" product development, precision injection molding precision injection molding machine as a key basic equipment, molding products in the size of repeat accuracy, quality and duplication inherent in molding precision and efficiency of the three aspects have been greatly improved. Compared to conventional injection molding equipment, precision injection molding machine for the real implementation of the precise control products and precision production. Then, precision injection molding technology "precision" are reflected in the Where?
     To achieve high-speed precision injection molding plastics injection molding machine is an important feature. General, high-speed injection speed can reach 300 ~ 1000mm / s, some even to the injection molding equipment 2000mm / s. Injection speed for not more than 500mm / s of the injection molding process, the use of coaxial line-type devices and plastics injection molding at the same time, and when the injection speed of more than 500mm / s, the use of coaxial line-type device is very difficult to achieve the required injection accuracy and the quality of plastics, mainly due to the easy installation of high-speed injection molding so that when the molten plastics material back, resulting in measurement of molten materials are not allowed and the deterioration of quality.
     To address this problem, according to the characteristics of precision high-speed injection molding, can be "IMC" plastics injection-type devices, that is, the traditional first-line-type coaxial devices, and plastics injection molding into contact with each other and function of two separate devices, in part by the extrusion screw plasticization completed and part of the injection molding plunger completed, so as a result of the plunger and the injection molding machine injection cylinder gap between the wall is far less than the injection molding machine screw and barrel wall / only gap between the circle, effectively avoiding the high-speed injection molding plunger when in the molten material may lead to back flow of sewage, and are not independent plastics molding cycle, which greatly improved the quality and plasticization plasticization capacity.
     All-electric plastics injection molding plastics injection molding equipment used in precision devices, can significantly improve the plastics injection molding equipment, displacement, speed plastics, plastics back pressure, injection pressure itinerary and plastics injection molding parameters such as control precision, therefore, in precision injection molding machine has been widely used.
