For injection molding machines, scale may gradually occur after a period of use. It should be noted that scale does great harm to the injection molding machine. In order to ensure the stable operation of the equipment, it is necessary to avoid the harm of scale to the equipment. So, how to avoid injection molding machine Harmed by scale?

　　 1、 Cooling system

1. Raw material caking and poor sealing affect the normal operation of the injection molding machine. The cooling system of the injection molding machine continuously cools the oil temperature, scales and blocks, the cooler heats, and the raw materials at the material port are caked, affecting production. In serious cases, the sealing system of the rubber cylinder is poor, the sealing ring is hot, deformed, leaks oil, and the product is unstable, which has a great impact on the normal operation of the overall equipment.

2. Poor cooling effect, defective products increase. Injection molding machine manufacturer It is believed that the size of the mold runner and water separator will lead to poor cooling effect of the mold, increased defective products, a large loss of raw materials, and a decline in product qualification rate.

　 2、 Heat exchanger system

1. The heat transfer efficiency is hindered, and the technology and cost are affected. The scaling on the surface of the heat exchanger actually increases the thickness of the pipe wall, increases the heat transfer resistance and reduces the heat transfer efficiency of the heat exchanger, which not only does not meet the requirements of the technical system, but also increases the operating costs of the enterprise.

2. High fluid resistance and high pressure drop. After scaling of heat exchanger tubes, fluid resistance increases and pressure drop is high.

3. Corroded equipment and high repair rate. The injection molding machine manufacturer believes that the dirt of the injection molding machine will corrode the equipment and shorten the service life of the injection molding machine. The equipment needs constant repair, which is time-consuming and labor-intensive.

The above is about how to prevent the injection molding machine from being damaged by scale. Correct operation, adjustment and timely maintenance can not only improve the quality and output of the injection molding machine, ensure the injection precision of the injection molding machine, but also reduce the damage to the parts of the injection molding machine, ensure the normal operation of the injection molding machine, extend the life of the injection molding machine, and improve the investment efficiency.
