MACHADO RODRIGUEZ, Ángel Silvio et al. Sintering, a process of metal forming as an economic alternative with a low environmental impact. cen. az. [online]. 2017, vol.44, n.3, pp.83-92. ISSN 0253-5777.

Sintering is a process of metal forming using metal powders, and it has a wide range of applications including for example, the manufacturing of parts for automotive components, home appliances, cutting tools, power tools, for the manufacturing of dental devices, among others. The process is characterized by the production of large-scale low cost parts and has a low environmental impact compared to other existing technologies, it requires less energy for processing and enables high utilization of raw materials. Also, it has the characteristic of obtaining, in most cases, the parts with final tolerances necessary for direct use by the customer, which ultimately reduces considerably the cost of production. The process is characterized by minimizing the loss of raw materials; facilitating precise control of the desired chemical composition; eliminating or reducing machining operations; providing a good surface finish; being an easy production process of automation; obtaining high purity; and ensuring exactly resistance characteristics required for each project.
