Controlling hydrogen gas in aluminium melt

<p>Reduced Pressure Test is used to measure&nbsp; hydrogen gas in aluminium melt. Hydrogen is the only gas soluble in aluminium and may at solidification precipitate as porosity in the cast component. Therefore the level…

Qualiflash - Analysis of fluidity in aluminium melt

Qualiflash® is an equipment that is used to provide a quality index for aluminium melts used for casting. It is important that an aluminium melt is as clean from oxides as possible in order to produce castings of high quality.

Measurement of porosity level in cast aluminium

When casting aluminium porosity might form in the component due to hydrogen, air or other defects in the material. Measurement of porosity level is an effective way of investigating the amount of porosity in cast aluminium.

Substitution of hazardous substances in metal

Good metallic properties and non-toxic constituents are important in circular material flows. However, the substitution of substances can affect the metallic properties. We can help you with simulations, knowledge of the impact of…

Cast process

The properties of a cast component are affected by several factors; material selection, alloy element, geometry, solidification rate and the stability in the cast process, type of used cast process. At RISE, we have the resources…

Substitution of hazardous chemicals

Non-toxic and circular cycles are a focus area in Sweden’s circular economy strategy. Hazardous chemicals in products and processes need to be replaced in order to protect human health and our environment. RISE has expertise in ev…

Courses in foundry technology

We offer a range of courses in foundry technology. Here you will find both breadth and depth, from introductory courses in foundry technology, die casting and design and optimization of cast components, to casting defect analysis …

Casting imperfection analysis of aluminium

The course provides basic knowledge about aluminum as a cast metal and about how melt handling affects the casting result. Increased knowledge also improves the possibility of producing aluminum castings with increased quality.
