Introduction to Additive Manufacturing: Part Two

Additive manufacturing is a relatively recent manufacturing method which has become a key area of interest in multiple industrial sectors.
As the application and growth of AM occurs, several systems to classify the AM processes have developed, including one proposed by the American Society for Testing and Materials (ASTM) F42 Committee. Continue reading

The ROMELT Process

The Romelt process is born and driven by the ever present need to design effective steel and iron making processes which are much cleaner in respect to their environmental impact.
First industrial Romelt plant is currently being constructed in Burma and is expected to have a design annual capacity of 200,000 tpy. Continue reading

Introduction to Additive Manufacturing: Part One

Additive manufacturing is a relatively recent manufacturing method which has become a key area of interest in multiple industrial sectors.
Deriving from CAD models the process can be used to create solid yet highly complex parts and pushes towards a tool-less manufacturing environment meaning improved quality and better efficiency in many cases. Continue reading

Semi-Solid Rheocasting of Alumina Alloys: Part One

Aluminum is well established at the front of the pack with regards to providing the technological answer to the increasing challenges of light weighting whilst maintaining integrity of the material for the desired applications.
Semi solid rheocasting is a development within the casting sector which enables improved quality in die casting without increasing cost. Continue reading

Shape Rolling

Shape rolling of steels is a process which requires a lot of heat and a lot of force. Reheating is carried out to around 1200°C and then the metal is continuously fed through rollers to draw the desired dimensions.
Popular shapes have good application in the construction business as I, H, and U shaped beams or girders can be produced for structural integrity

Deep Drawing of Aluminum Alloys: Part Two

Deep drawing is one of the most intensively studied process areas due to its close relationship with the automotive industry with focus not only on visual appeal but also paramount safety concerns.
However the most important benefit of using aluminum materials in the forming of automotive body parts is the high weight loss factor associated with these materials.

Deep Drawing of Aluminum Alloys: Part One

Driven by the notoriously high demands of the automotive industry the quest to find more efficient, cheaper and better quality methods to produce materials is ever present.
Deep drawing, the process of turning sheet metal into hollow parts, is a critical production process and from the measurement of certain material properties it can be seen that aluminum has favorable performance when compared to steels.

The Water-Atomizing Process: Part One

Water atomizing of metals is now a commercially important methodology to achieve fine particle distribution for a range of materials.
The general process is effective by impinging a falling stream of molten metal with jets of water which immediately solidify the metal into granules (>1mm) or powder (<1mm). Compared to less modern techniques like crushing and grinding water atomization presents a cost effective and efficient approach to producing metallic powders.
