Casting, forging, stamping, die-casting, what are the differences between them? What are the processing processes?

Casting: A metal forming process that directly injects molten metal into a casting mold to form a certain shape. The raw materials are melted and allowed to form naturally in the forming mold, and the quality is slightly worse. Casting is divided into two types: high-pressure casting and low-pressure casting. Simply put, after the metal is melted, the pressure of pressing the mold is different, and the temperature of heating the metal and the machine used for casting are different. Die-casting:...

What are the hazards of high-pressure hydraulic press hydraulic oil after being contaminated

The way the oil of the high-pressure hydraulic press is contaminated is mainly due to the alternating cooling and heating of the oil tank cap, which causes the moisture in the air to condense into water droplets and fall into the oil tank. Oil; the seal of the cooler or heat exchanger is damaged, or the cooling pipe is broken, causing water to penetrate into the oil; due to the tight sealing of the hydraulic cylinder piston rod, the humid air entering the system condenses into water droplets;...
