Low-pressure casting is a kind of equipment often seen in the industry. It is a special process. Many times 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. Factors affect it.
What factors affect the process of low pressure casting:
1. The batch size of low-pressure castings: the larger the batch size, the greater the economic benefits.
2. Clean out: There is no chemical binder in the molding sand, foam plastic is harmless to the environment at low temperature, and the recovery rate of old sand is more than 95%.
3. High precision of low-pressure casting: iron casting is a new process with almost no margin and precise forming. This process does not require mold taking, no parting surface, and no sand core, so the casting has no flash, burr and draft angle , And reduce the size error caused by the core combination.
4. The low-pressure casting process is the same as other forging processes, with its shortcomings and limitations. Not all castings are suitable for production using the lost foam process, and detailed analysis is required.
5. Reduce investment and production costs, reduce the weight of casting blanks, and have a small machining allowance. Highly complex castings can be forged through the combination of foam plastic die pieces.
6. Low-pressure casting casting material: 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; As a result, the process experiment and debugging cycle is too long.
