Choosing an energy-efficient aluminium melting furnace comes down to four things: specific energy consumption, furnace type, heat recovery, and control system. Get these right, and you cut your energy bill by 20–40%. Get them wrong, and you pay for it ...

How a Chinese expert helped a European aluminium recycler cut melt loss from 9.2% to 4.6%. Temperature, salt flux, skimming, burner tuning, and training. In late 2023, I received an email from a recycling plant manager in northern Spain....

A die casting furnace that will not hold setpoint temperature is a serious problem. It affects casting quality, cycle time, and scrap rate. In my 25 years, I have traced this issue in foundries across China, Southeast Asia, India, the UK, Eur...

A furnace that will not reach setpoint temperature is not necessarily broken. It is telling you that heat is being lost faster than it is being added. The cause is usually one of six things: a damaged lining, leaky door seals, a misadjusted burner, low...

Fix inconsistent aluminium melt quality. Causes: temperature, alloying, contamination, fluxing, degassing. 25 years of foundry experience. Inconsistent melt quality is one of the most frustrating problems in a foundry. One day the castings a...

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...

Fix an aluminium furnace that overheats frequently. Check thermocouple, controller, gas valve, air-fuel ratio, and safety limits. 25 years of foundry experience. A furnace that overheats frequently is not just wasting energy. It is damaging your refra...

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...

In early 2024, I received an email from a procurement manager at a US aerospace supplier. His company produces precision aluminium components for commercial aircraft. They had been sourcing castings from a Chinese foundry for three years. The quality w...

In early 2024, I received a call from a recycling plant manager in Guangdong Province. His plant processes mixed aluminium scrap into ADC12 ingots for the automotive and appliance markets. His metal recovery rate had fallen to 84%. That meant...
