With the wide application of high-speed injection molding machines, it has increasingly become one of the injection molding machine products that plastic product manufacturers pay attention to. However, what is the difference between a high-speed injection molding machine and an ordinary injection molding machine? became a hot topic of discussion. After reading this article, you will learn:
What is a high-speed injection molding machine?
A high-speed injection molding machine means that it will have a high-speed injection control system and a high-speed clamping system.
In terms of visual function, the high-speed injection machine will increase the injection machine accumulator
How to achieve high speed? We focus on the following parts:
1. High-speed injection, high precision
If we come across a thin walled cup project, if we put this kind of mold on a normal machine, the part will be very difficult to shape.
We might be able to turn up the high injection pressure, which also affects mold life.
However, there are specially designed valves inside the high-speed injection molding machine.
Used in conjunction with servo hydraulic motor, it has good injection control function.
2. High-speed clamping system, fast cycle
According to common sense, the larger the tonnage, the longer the cycle time,
The problem is that with larger tonnage injection molding machines, the clamping time will be longer.
What is the difference between a high-speed injection molding machine and an ordinary injection molding machine?
The difference between high-speed injection molding machine and ordinary injection molding machine:
- The molding process of an ordinary injection molding machine is: mold clamping - injection - cooling - material storage - mold opening - mold support - gap time.
- The high-speed injection molding machine is efficient. The high-speed injection molding machine adopts three-axis linkage, which is commonly referred to as three-circuit. The molding process is: mold clamping - injection - cooling - mold opening (synchronous mold support, material storage) - gap time. For example, the molding time of a product with an ordinary injection molding machine is 10 seconds, while the high-speed injection molding machine uses the principle of three-axis linkage, and the molding time is greatly shortened by about 6 seconds, minus two small steps, but the time is increased by about half the speed.

The high-speed injection molding machine is environmentally friendly. The standard pump used by the ordinary injection molding machine has a large pollution in terms of electricity, hydraulic oil and noise.
The soft start has no effect on the die implementation, avoiding voltage and spoke contamination. It can effectively prevent the oil temperature from being too high and cooling down. Greatly reduce the replacement rate of hydraulic oil. The servo hydraulic system can greatly reduce the noise of machine operation and production and improve the working environment due to better clicking sound and power system gear pump.
How to choose the right high-speed injection molding machine for you?

Technical parameters of injection molding machine
When users choose a high-speed injection molding machine, they can be judged by vertical or horizontal comparison. The so-called "vertical" means that the main technical parameters of the injection molding machine should meet the industry standards and be examined according to the industry standards. The so-called "horizontal" is compared according to the technical parameters of similar high-speed injection molding machines at home and abroad. Therefore, this is a very careful scientific work. It should be based on the material, shape, structure, and even the application field and specific occasion of the injection molded product; according to the structure, quality, precision, number of cavities, type of runner and its structure, shape, and size of the mold; The annual production capacity automation degree, etc. to select the parameters of the high-speed injection molding machine at all levels.

Choose a supplier
It is best to choose a manufacturer with a nearby service office to purchase, because the high-speed injection molding machine has a complex structure, and it is inevitable that problems will not occur. Fast after-sales service is very important. Don't blindly seek low prices when purchasing. Now the accessories on the high-speed injection molding machine are domestic and Imported prices vary widely, so you need to try to figure out what brand of accessories the manufacturer is using. Of course, you can't see some accessories, such as oil seals, bearings, etc., so the popularity and credibility of the manufacturer are very important at this time.

Select the model
The two main parameters of a high-speed injection molding machine are shot volume and clamping force. In order to ensure the quality of the processed products, the actual weight of a mold product should be within 70% of the theoretical injection volume of the machine. Calculate the required clamping force according to the projected area of the product. And pay special attention to the distance between the columns of the machine, the mold opening stroke and whether the minimum mold thickness is suitable for the mold.

Human-machine dialogue ability and operability
The high-speed injection molding machine should make its operation and management more user-friendly, the operation should be convenient, and the display should be clear, easy to understand, and clear at a glance. It has the function of parameter selection, product quality control, storage of mold data and automatic reproduction of various parameters, which can quickly diagnose and eliminate faults, reduce material waste in the shortest time, and restore the normal operation of the system.
