Selective laser sintering 1970-01-01
Selective Laser Sintering (SLS) is an advanced additive manufacturing technique that uses a laser to fuse powdered materials into solid structures. It is widely used for creating prototypes, functional parts, and complex geometries in various industries, including aerospace, automotive, and healthcare. ### How SLS Works: 1. **Powder Bed Preparation**: A thin layer of thermoplastic powder (such as nylon, polyamide, or other materials) is spread across a build platform.
Semi-solid metal casting 1970-01-01
Semi-solid metal casting (SSM) is a casting process that involves the use of metal alloys in a semi-solid state, which is characterized by a mixture of solid and liquid phases. This technique combines aspects of both traditional casting and forging, allowing for the production of complex shapes with improved material properties.
Shock hardening 1970-01-01
Shock hardening refers to a process in which materials, often metals, are subjected to high strain rates or impact loading that results in an increase in their hardness and strength. This occurs due to the rapid deformation mechanisms activated under such conditions, which can lead to a variety of microstructural changes in the material. Key aspects of shock hardening include: 1. **Strain Rate**: The high strain rates involved in shock hardening differ significantly from conventional deformation processes.
Silent butler 1970-01-01
A "silent butler" is a small, typically elegant receptacle used to keep and transport crumbs, small waste, or leftover food from a dining table. It is designed to discreetly gather these items without making a mess and is often made from materials like wood, metal, or ceramic. The term often refers to a device that has a hinged or removable top to allow for easy access and cleaning.
Sintering 1970-01-01
Sintering is a manufacturing process used to create solid materials from powders through the application of heat and (often) pressure. The main objectives of sintering are to increase the density and strength of the material by promoting particle bonding, which occurs without melting the primary constituent materials. ### Key Features of Sintering: 1. **Process Steps**: - **Powder Preparation**: Fine particles are prepared, often through milling or other methods to achieve the desired particle size and characteristics.
Skiving (metalworking) 1970-01-01
Skiving is a metalworking process used to achieve precise dimensions and a smooth finish on the outer or inner surfaces of a workpiece. It involves the removal of material through a cutting action, typically using a specifically designed tool or machine called a skiving tool or skiving machine. In skiving, the tool's cutting edge is presented to the workpiece at a slight angle, allowing it to shave or slice off thin layers of material.
Slitting mill 1970-01-01
A slitting mill is a type of machinery used in the metalworking industry to cut large rolls of material, often flat metal sheets or strips, into narrower strips or coils. The process is known as slitting, and it typically involves feeding the metal strip through a series of rotating blades or knives that create multiple narrower strips from the wider material. Slitting mills are commonly used in steel and aluminum processing, allowing for efficient production of various products such as metal roofing, electrical components, and automotive parts.
