Metal loss in secondary aluminium melting is not a single problem. It is a chain of losses — oxidation at the melt surface, metal trapped in dross, salt slag carryover, and furnace atmosphere reactions. Each link in the chain has a different cause and ...

Setting up a die casting furnace is not about turning a dial to a number on a chart. It is about matching the furnace to the alloy, the die, the machine, and the part. Get it right, and you produce consistent castings shift after shift. Get i...

Aerospace-grade aluminium is not just cleaner than commercial-grade. It is a different class of material. The hydrogen content must be below 0.06 ml/100g. The inclusion count must be measured in parts per billion, not parts per million. And e...

Gas porosity is the most common internal defect in aluminium die casting. It shows up as round, smooth cavities on X-ray. It causes leaks in structural parts. It ruins machined surfaces. And it costs foundries millions in scrap every year. In my 25 ye...

A380 and ADC12 are the two most common aluminium die casting alloys in the world. They look similar on a spec sheet. They behave differently in a furnace. If you run both alloys on the same line — as many foundries do — you need to understand the tempe...

Rotary furnaces are the workhorses of aluminium recycling. They handle contaminated scrap, dross, and low-grade material that other furnaces cannot process economically. But they are also energy-intensive. In my 25 years, I have seen rotary furnaces co...

A preventive maintenance schedule is not a document you file away. It is a habit you build. In my 25 years, I have seen foundries with 20-year-old furnaces that run like new, and foundries with 5-year-old furnaces that break down every month. The diffe...

Practical ways to reduce oxidation loss in aluminium melting. 25 years of foundry experience. Cut metal loss, improve yield, and lower costs. Oxidation loss is the silent thief in your foundry. You melt a tonne of aluminium, but you pour less. Where d...

Practical guide to optimising burner efficiency in gas-fired aluminium furnaces. 25 years of foundry experience. Cut fuel costs, reduce emissions, improve melt quality. Optimising burner efficiency comes down to four things: correct air-fuel ratio, re...

Daily, weekly, and monthly maintenance checklist for aluminium melting furnaces. Based on 25 years of foundry experience. Reduce downtime and extend furnace life. A good maintenance checklist is not a piece of paper. It’s a habit. It prevents small pr...
