Die casting, a high precision casting process is usually used for die castings with dimensional requirements, such as aerospace, automotive, custom equipment, etc., precision components, all processes are completed in the machine, including injection, pressure-holding, and cooling.

Sand casting, a low-cost casting method, half manual, and half machine operation, multiple layouts in one cavity, molds and cores no need high cost, no high requirements for mold appearance and steel hardness, subsequent appearance treatment after forming, almost no requirements for product density and accuracy.Can be used for a wide range of casting materials.

Investment casting, a complex process of casting for die castings with complex shapes and structures. The first step is to make a wax mold with a similar structure as the plastic mold, fill it with wax and shape it (the shape of the wax is the shape of the final die casting); the second step is to take the product out and coating it evenly with two special materials, the first coating is fine to make the surface of the die casting smooth and ensure that the wax product will not crack easily at a certain temperature after air-drying the second coating is applied, the second coating will form the mold of the part shell, the melting point of the coating is a little higher than the melting point of the die casting; the third step into the furnace, the surface material after high temperature to form the shell, the wax has been melted, Investment Casting is formed, pour the melted die-casting material and cover for insulation, crack the shell to remove the part.

Low-pressure casting, a simple casting method that differs from high pressure die casting in three ways: 1. the molten metal is injected into the die using air, 2. the furnace is placed at the bottom of the die to facilitate air pressure, and 3. the shape of the product must appear to be a mirror image to facilitate pressure balancing within the die. low-pressure casting is not suitable for most die castings. The reason sees here.

Gravity die casting, the simplest form of casting, with only a cavity and a core, not even a machine to clamp it, the molten metal is poured in through the top of the die and knocked out when it cools, suitable for small batches of die castings.

Vacuum die casting, a method of improving the quality of casting, usually for magnesium alloys, where the air is pumped out of the cavity before the molten metal is fed in (some special dies are injected with oxygen after the air has been pumped out) and then the metal is injected, resulting in a die casting with fewer pores and high density, which is more complex in batch production conditions and prone to explosions caused by leaks.
