Working medium of hydraulic press.

Hydraulic presses can be widely used in cutting, punching, blanking, bending, riveting and forming processes. The hydraulic press applies pressure to the metal blank to plastically deform and fracture the metal into parts.

The function of the working medium of the hydraulic press is to transmit the pressure to ensure that the working parts of the machine are sensitive, reliable, long-lived and less leaking.

The basic requirements of hydraulic press working medium: ① suitable for fluidity, low compressibility, improve transmission efficiency; ② anti-corrosion; ③ good lubrication performance; ④ easy to seal; ⑤ stable performance, long-term work without deterioration.

The hydraulic press adds a small amount of emulsified oil to the water to increase lubricity and reduce rust.

In the 19th century, a hydraulic press using mineral oil as a working medium appeared. The oil has good lubricity, anti-corrosion and viscosity, which is beneficial to improve the performance of hydraulic presses. In the second half of the 20th century, a new type of water-based emulsion appeared, and its emulsified form was "water-in-oil" instead of the original "oil-in-water". The external phase of the "water-in-oil" emulsion is oil, which is close to oil in lubricity and anti-corrosion, with little oil content and not easy to burn. Water-based emulsions are expensive and restrict promotion.

Yingxin World Machinery was established in Shanghai in 2009. It is the export center of all world-brand machines authorized by the World Group, including power presses, hydraulic shears, hydraulic bending machines and automation accessories. World Precision Machinery (China) is the largest branch of the World Group, focusing on the production and technical research of power presses. The original factory was built in 1953 to produce small eccentric punches for the new Chinese industry. World Group acquired this factory in 1998 and expanded its production capacity and product range. With more than 65 years of professional experience and strong production capacity, we believe that world-brand metal forming machines will provide better services to the international stamping industry. The Shanghai Export Center is working hard to accomplish this mission.

The hydraulic press is powered by hydraulic cylinders. We supply C frame single-column hydraulic press, four-column hydraulic press and box column hydraulic press. The hydraulic cushion under the pillow is optional. The hydraulic press is most suitable for the stamping and stretching of sheet metal parts. It is suitable for the production of deep-drawn parts such as kitchen sinks, rice cookers, pans, cups, filter chambers, tin cans, etc. The hydraulic press is also suitable for hot forging.

If you are satisfied with our company's hydraulic press and bending machines, you can directly order or consult hydraulic press related issues. We will provide you with the best hydraulic press products and services. Looking forward to your visit, I wish you success in your work.
