What is the difference between high pressure casting and low pressure casting?

Time:2017-12-13 Click:Second

Foundry is an important part of our modern technology. The effect of casting products is very good. Gravity foundries have a fairly high level of technology. So what's the difference between high-pressure casting and low-pressure casting?

High pressure casting is the high-speed pressing of liquid metal into the mould cavity by a hydraulic cylinder-driven pressure nozzle, which is commonly called high pressure casting because of its high pressure and high oil pressure. Low pressure casting is the hydraulic pressure of metal into the mould cavity through air pressure, which is generally 0-2Kg/cm2, so it is generally called low pressure casting.

In industrial production, various kinds of moulds and tools are obtained by injection, blow moulding, extrusion, die casting or forging, smelting and stamping. In short, the die is a tool used to shape objects. This tool is made up of various parts, and different dies are made up of different parts. It mainly realizes the processing of the shape of the object by changing the physical state of the forming material. Known as the "mother of industry".

Foundry is a kind of metal hot working technology that human beings have mastered earlier, and it has a history of about 6000 years. Between 1700 BC and 1000 BC, China has entered the peak period of bronze castings and reached a fairly high level of technology. Casting is a method of casting liquid metal into a casting cavity suitable for the shape of the part and then cooling and solidifying it to obtain parts or blanks. [1] The cast material is mostly solid but heated to liquid metal (e.g. copper, iron, aluminium, tin, lead, etc.), and the material of the casting mould can be sand, metal or even ceramics. According to different requirements, different methods will be used.

Mould is the tool used for forming. High pressure casting is to complete the forming tool with the mould. Different casting materials will have different casting methods, and the final effect will be different.
