Injection molding machine equipment control system

The injection molding machine control system is generally composed of computers, electrical components, hydraulic components, servo controllers, closed-loop control systems, etc. Due to cost reasons, the domestic injection molding machine does not have a closed-loop control system as standard. Unless there are special requirements, it is all open-loop control. The so-called servo motor closed-loop control is only the motor speed servo control, not the injection molding machine pressure and flow closed-loop control. 

                                         

At present, domestic injection molding machine computers include imported and domestic products. If they are general products, everyone will perform similarly, and the computer will rarely be bad. But for the products with high-speed, thin-wall and high-precision requirements, the difference between computers comes out because of the difference in computer response time. Injection molding machine manufacturers specially design injection molding machines based on customer products, and their computers basically meet the requirements of their injection molding machine performance.

 

Compared with the injection molding machine computer, the servo controller has more problems, but there are not many domestic suppliers in the servo control, so the failure rate of this aspect, the performance of various brands is not much different. Hydraulic control components are already very mature abroad, and there are only a few manufacturers, and the failure rate is very small. However, domestic manufacturers perform in this regard and have more problems. It's just that the domestic hydraulic accessories used on the injection molding machine are rarely used, and most injection molding machines are basically not used.
