Why do plastic injection machines need hydraulic oil?

Among the parts of a plastic injection machine, the hydraulic system must be mentioned. The main task of this system is to provide force to close and open the mold to create and maintain the clamping force that causes the screw to rotate and move back and forth, creating force for the ejector pin and the sliding of the side core. The hydraulic system consists of many parts such as oil tanks, pumps, valves, motors, and pipelines. For the hydraulic system to operate smoothly and stably, hydraulic oil must be present. Hydraulic oil plays the role of lubrication, power transmission, anti-oxidation, anti-wear and anti-rust and cooling.

Using hydraulic oil properly will help companies save significant fuel resources, helping to increase the life of injection and extrusion plastic molding machines.

What benefits do you get when using hydraulic oil for plastic injection machines?

If your business understands the role and reasons for using hydraulic oil for plastic injection machines, we recommend that you use high quality oil. Because high quality hydraulic oil has good effects on both old and new plastic injection molding machines. They help machines operate stably and bring precision during power transmission operations. Here are the benefits you will receive when using hydraulic oil for plastic injection machines.

Benefits of using industrial oil

 Helps save energy and reduce wear and tear during operation

In difficult economic times, with rising gasoline prices, fuel economy is of special concern to many people. When a plastic injection molding machine operates, 15% of the energy produced is consumed by friction, more than 50% by heat and just under 35% by generating useful work. High friction will cause machine parts to wear out and become fuel-hungry. At this point you need the help of hydraulic oil.

Hydraulic oil acts as a membrane to prevent friction. The oil will minimize overall friction in the engine and reduce fuel consumption. Lubricant companies are always trying to develop new products that help reduce energy consumption due to friction by creating products with optimal viscosity.

 Lubrication reduces friction to help the hydraulic system operate smoothly and conveniently, avoiding wear and tear

As we said above, when using hydraulic oil, the hydraulic system of the plastic injection machine is lubricated, operates smoothly, and reduces wear and tear. Once the parts operate smoothly, without any problems, the production pace will be guaranteed, and the machine's productivity will be promoted to create the best products. Limiting wear and tear not only saves fuel but also saves money on replacing parts or maintaining the machine.

Increase the lifespan of machinery and equipment

Friction and heat are the two biggest enemies that shorten the life of machines.Hydraulic oil is the fuel that helps reduce the power of these two saboteurs. Hydraulic oil helps lubricate, reduce friction, reduce corrosion of machine parts, and increase the life of plastic injection machines. Instead of not using hydraulic oil, you can use the machine for 10 years, but if you use hydraulic oil, you can use the machine for up to 20 years.

In addition, hydraulic oil also has a cooling function. During operation, the machine will spread the oil evenly on the contact surfaces, the oil will absorb heat and roll back to the tank. Here the oil will help the machine radiate heat. Reducing heat will reduce the risk of fire and machine explosion.

Anti-rust, anti-corrosion, anti-sludge, anti-foam causing damage to internal parts

Hydraulic oils are quite inert to all temperatures. At low temperatures the oil does not thicken and at high temperatures the oil does not degrade. Plastic injection machines continuously generate heat to melt, so the hydraulic oil used in plastic injection machines must be an oil with extremely good inert properties. Even at high temperatures, the oil does not form precipitates or dirt that sticks to and damages machine parts.
