What need to know about low pressure casting
low pressure casting is a method of pressing liquid metal into a metal mold with pressure ranging from 8 to hundreds of ata.
+ High casting mechanics thanks to high casting density.
+ High productivity (100 ÷ 200 casting / hour) thanks to fast filling and favorable mechanization ability.
+ The casting has high precision and gloss (accuracy reaches 0.01 mm).
+ The inner surface of the casting is also highly glossy because the core of a metal cannot be used but the sand core cannot be used.
+ Casting thin objects (thickness> 0.3 mm) and complex objects (holes with a diameter of 1.5 ÷ 3 mm can be cast) because liquid metal is pressed into the mold, so it has good filling capacity.
+ Due to casting in a metal mold, the object cools quickly and has good mechanical properties.
Disadvantages of low pressure casting
+ Can not use sandblasting because the flow is pressurized. Hence the shape of the hole or the inside face must be simple.
+ Mold quickly wears out due to the pressure flow of the alloy at high temperature.
+ Less used for casting black metal because the melting temperature of black metal makes mold durability decrease.
Application: Casting under pressure is used to manufacture complex details such as oil pump casing, pressure chamber cap, air valve, brass pipe, …
