High dosing accuracy of ±1.5 %
Metal loss of just 0.06%
Uses 2/3 less energy than ladle/holding furnace
98% system uptime
The crucible-free Westomat Classic dosing furnace is a clean, closed holding and dosing system for liquid aluminium. With unparalleled dosing accuracy, extreme energy efficiency, unrivalled uptime, and metal loss as low as 0.06%, our original dosing furnace continues to be the ‘go to’ solution for aluminium casting. The Westomat Classic helps customers cut scrap, energy consumption and – thanks to being super easy to install, integrate, operate and maintain – eases pressure on foundry resources. All of which means more castings of consistent quality, at reduced cost.
High metal yield, high metal quality, dependable delivery
Dosing furnaces are known to reduce metal loss by up to 80% in comparison to stand-alone holding furnaces with automatic ladle systems.
Our Westomat Classic’s many clever design and operational features maximize this advantage to always deliver the right amount of high-quality melt, exactly when needed. Here’s how:
1) Better metal made simple
The Westomat Classic offers the option of porous plugs which allow inert gas to be dispersed into the melt via extremely fine bubbles to remove hydrogen and other impurities from the liquid metal to enhance melt quality – lowering the risk of production scrap further down the line.
Additionally, with our famous dosing furnace liquid aluminium is kept at a constant temperature and is always removed from below the bath surface via a flanged riser tube (which can be extended to specifically suit structural component casting). This allows the liquid metal to be transported directly to the die-casting machine or mould automatically and free of oxide contaminations that decrease the likelihood of defective castings.
2) Complete control. Always.
The Westomat Classic’s intelligent control system has always made managing precision dosing simple. Our new and improved ProDos4 control solution just made things even easier.
Its enhanced user interface and algorithms help foundries seamlessly monitor and analyze machine data (current or historic), run diagnostics and adjust settings. Built in biscuit correction for example, ensures dosing weight is continuously and automatically adjusted for optimal accuracy. What’s more, our new Web Server option ensures all this can be done remotely and securely, and that information key to efficient management can be easily shared.
3) Dosing accuracy by design
Dosing accuracy isn’t just down to having the right software. It’s also about the right technical solutions. Our PneuCo pneumatic top stop detection system is one example. It uses air pressure waves to generate electrical pulses that precisely manage dosing timing and melt volume. Another example is our Rim Cleaning Jet which cleans the riser tube rim of aluminium deposits that can impact dosing precision. Both systems also reduce maintenance requirements and help improve uptime.
