Sintering is a manufacturing process that involves heating powdered materials, often metals or ceramics, to a temperature below their melting point. This heat causes the particles to bond together, resulting in a solid mass with improved strength and density. Sintering is commonly used in the production of components for industries such as automotive and aerospace. The process typically occurs in a controlled environment, where factors like temperature and time are carefully managed. Sintering can enhance the properties of materials, making them suitable for various applications, including 3D printing and metal fabrication.
