Casting material of low-pressure casting parts: the order of good and poor suitability is roughly: gray cast iron-non-ferrous alloy-ordinary carbon steel-ductile iron-low carbon steel and alloy steel; Through necessary preparation, the process experiment and debugging cycle will not be too long.

Low pressure casting is a kind of equipment that is often seen in industry. It is a special process. Most of the time, we will pay more attention to the production process of low pressure casting. Let's take a look at the process of low pressure casting.

What factors will affect the process of low pressure casting parts:
1. The batch of low-pressure casting parts: the larger the batch, the more considerable the economic benefits.
2. Clean out: there is no chemical binder in the molding sand, the foam is harmless to the environment at low temperature, and the recovery rate of the old sand is more than 95%.
3. High precision of low pressure casting: cast iron is a new process with no margin and precise molding. The process does not need to take mold, no parting surface and no sand core, so the casting has no flash, burr and draft inclination, and reduces the size error caused by core combination.
4. Low pressure casting process and other forging process, has its shortcomings and limitations, not all castings are suitable for the use of lost foam process to produce, to carry out a detailed analysis.
5. Low-pressure casting structure: the more complex the casting structure, the more it can reflect the superiority and economic benefits of the iron casting process. For the case of narrow inner cavity channels and interlayers on the structure, it is necessary to pre-improve the predecessors before using the vanish mold process.
6. Reduce investment and production costs to reduce the weight of the casting blank, machining allowance is small. Highly complex castings can be forged by foam die sheet combinations.
7. Casting material of low-pressure casting parts: the order of good and poor suitability is roughly as follows: gray cast iron-non-ferrous alloy-ordinary carbon steel-ductile iron-low carbon steel and alloy steel; Through necessary preparation, the process experiment and debugging cycle will not be too long.
