Armed with innovative 3D printing technologies, engineers have designed a new generation of microturbines capable of unparalleled operating efficiency at higher speeds and elevated temperatures.Continue reading
Additive manufacturing, or 3D printing, has been on the rise since the early 1980s yet it is still considered an immature technology. The first iterations used photo-hardening of thermoset polymers to generate three-dimensional models via masking or fiber scanning. There are now a myriad of techniques available to generate components via deposition as opposed to conventional machining, yet 3D printing is still generally used for prototyping and hobbyist applications. Significant investment has been made in industrial spaces to help realize the commerciality of additive manufacturing at appropriate scales, particularly for technical ceramic materials.Continue reading
Technical ceramics possess numerous properties that make them attractive engineering solutions for challenging applications. They largely outperform industrial-grade polymers and metals for high-temperature operation, with comprehensively superior mechanical properties and thermodynamic stability. Ceramic solutions are currently utilised in industries as varied as aerospace and defence, automotive engineering, chemicals and petrochemicals manufacturing, energy generation, and molten metal handling.Continue reading
Visit International Syalons and SILCA/Calsitherm at Hannover Messe 1–5 April 2019 at Stand L08, Hall 3, in the Ceramic Applications area.
Advanced ceramics manufacturing comprises three essential stages: raw powder processing; forming; and sintering. This generally describes the process of consolidating a powder-based feedstock and firing the green body to achieve a fully-densified technical ceramic. Net shapes with comparatively loose dimensional tolerances (~1-3%) can typically be produced ‘as-sintered’; requiring no machining or finishing prior to quality assurance inspections. Components with tight tolerances cannot be produced ‘as-sintered’ and may require diamond grinding to ensure that the net shape is usable according to the design intent.Continue reading
International Syalons are delighted to announce their British Ceramic Confederation (BCC) membership.
The BCC are a professional organisation who represent the collective interest of all sectors of ceramic manufacturing in Britain by working extremely hard to safeguard the industry’s prosperity and lead sector discussions and negotiations with Government and public authorities.
Extrusion describes the process where a metal such as copper or brass is forced through an extrusion die with a smaller cross-section. This deforms the material, causing a lengthening of its granular structure and forcing it to adopt a new cross-section uniformly across the entire manufactured workpiece. It is an extremely common metal forming process used to convert cylindrical billets into hollow tubes, or more complex profiles and sections.Continue reading
The 20th Century was an era of rapid innovation in ballistics technology, and subsequently in how conflicts were conducted. Military organisations worldwide opted to improve the manouverability of troops and vehicles without compromising the performance of protective equipment in response to high velocity impacts. This led to the gradual adoption of novel ceramic materials in defence applications.Continue reading
Grinding of industrial intermediates and various analytical samples is carried out by applying continuous abrasive force to reduce the size of particles, or to blend heterogeneous materials together. This can be carried out with hydraulic and pneumatic systems, but one of the oldest methods of grinding involves the use of milling media to repeatedly impact material and cause particles to decompose through mechanical attrition.Continue reading
