What is the difference between high-speed injection molding machine and ordinary injection molding machine

Aug 15, 2020

As high-speed products are more and more widely used, they have become more and more high-speed injection molding machines that business friends pay attention to. So what is the difference between high-speed injection molding machine and ordinary injection molding machine? This topic has been discussed.

 

    The actual analysis of high-speed injection molding machine is a combination of hydraulic and electric motor. Ordinary injection molding machines are pure hydraulic injection molding machines, while hydraulic injection molding machines rely on hydraulic oil to drive the relatively slow running speed, while high-speed injection molding machines use servo motors to open and close molds. Ejection and demoulding, raw material injection and storage, etc., the injection speed is fast and the position control is more precise, which greatly improves the production efficiency.

 

     But now the servo-electric injection molding machine only has a clamping force of less than 650 tons.

 

     The difference between high-speed injection molding machine and ordinary injection molding machine:

 1. The molding process of the ordinary injection molding machine is: clamping-injection-cooling-storage-mold opening-supporting mold-gap time.

 

2. The high-speed injection molding machine is highly efficient. The high-speed injection molding machine adopts three-axis linkage, which is generally called a three-circuit. The molding process is: mold clamping-injection-cooling-mold opening (simultaneous mold support, storage)-gap time. For example, the molding time of a product using an ordinary injection molding machine is 10 seconds, while the Dakumar high-speed injection molding machine uses the principle of three-axis linkage, which greatly shortens the molding time by about 6 seconds, minus two small steps, but increases the time by about Half speed.

 

3. The high-speed injection molding machine is environmentally friendly, and the standard pump used in the ordinary injection molding machine has greater pollution in terms of electricity, hydraulic oil and noise. In summary, the high-speed injection molding machine adopts a hybrid type of hydraulic and servo motor. The advantages of the servo hydraulic system are as follows: the implementation of soft-start molds will not affect the power network, and avoid voltage and electrical radiation pollution. It can effectively prevent the oil temperature from being too high and cool down well. Greatly reduce the replacement rate of hydraulic oil. The servo hydraulic system has better click and power system gear pumps, which can greatly reduce machine operation and production noise, and can better improve the working environment. Compared with ordinary injection molding machines, high-speed injection molding machines can save 60~70% of the total power consumption, greatly reducing costs and saving resources for customers.
