Application of additive manufacturing for improved thermal management of hot sheet metal forming tools
(Stellenbosch : Stellenbosch University, 2020-03)ENGLISH ABSTRACT: In hot stamping, a blank or sheet of metal at high temperature (800-900 °C) is formed and cooled simultaneously by the tools. The rapid cooling of the blank causes transformation to a martensitic ... -
Development of a selection program for additive manufacturing systems
(Stellenbosch : University of Stellenbosch, 2010-03)ENGLISH ABSTRACT: Additive Manufacturing (AM) refers to the technologies that use Computer Aided Design (CAD) data to produce plastic, metal, ceramic, paper, wax or composite materials parts. Their ability to join thin ... -
The effects of machine parameters on the integrity of WC-Ni coatings deposited onto titanium parts with laser additive manufacturing
(Stellenbosch : Stellenbosch University, 2019-04)ENGLISH ABSTRACT: Part quality specifications are of the utmost importance within industries that include specialized applications, for instance the medical, aerospace, nautical and mining industries. Attributable to the ... -
Investigation and management of residual stresses in selective laser melting of maraging steel
(Stellenbosch : Stellenbosch University, 2019-04)ENGLISH ABSTRACT: Selective Laser Melting (SLM) is a leading metal additive manufacturing process that has gained a lot of traction since the turn of the new millennium. Despite many benefits associated with SLM, a major ... -
Standard method for microCT-based additive manufacturing quality control 2 : density measurement
(Elsevier, 2018)ENGLISH ABSTRACT: MicroCT is best known for its ability to detect and quantify porosity or defects, and to visualize its 3D distribution. However, it is also possible to obtain accurate volumetric measurements from parts ... -
System development for the five-axis extrusion of a photopolymer
(Southern African Institute for Industrial Engineering, 2020-11-11)ENGLISH ABSTRACT: The development of a novel method of additive manufacturing involving the support-free extrusion of a photopolymer is discussed. The objectives of the paper are the presentation of mechanical and electrical ... -
Thermal management of moulds and dies : a contribution to improved design and manufacture of tooling for injection moulding
(Stellenbosch : University of Stellenbosch, 2011-03)ENGLISH ABSTRACT: Injection moulding of polymer components is subject to ever increasing demands for improved part quality and production rate. It is widely recognised that the mould cooling strategy employed is crucial ...
