Megacasting changes the scale. Larger clamping forces, larger molds \u2014 and a corresponding amount of smoke and oil aerosol with every cycle. For 30 years, we have been capturing and filtering emissions from die casting machines. Now we are scaling this experience for solutions on molds in the meter scale and clamping forces beyond 5,000 tons. Capture. Filter. Recover heat. Our systems intervene at three points: at the cell with an extraction hood or air curtain system, in the flexibly placeable filter system \u2014 and at the decentralized melting furnace, where most of the energy is located. <\/p>

Extraction at the source is the most efficient way:<\/p>

A concentrated exhaust air flow can be cleaned with a fraction of the effort that large volumes of air in hall ventilation would cost. At the same time, oil mist is kept away from machines, robotics, and the hall construction \u2014 and out of your employees’ breathing air. We plan emission protection and heat recovery as one system. <\/p>

Investing in the megacasting cell is the right moment for this.Secure your green competitive advantage.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Foundry planning and environmental technology from a single source: Megacasting becomes successful when hall layout, material flow, media supply, and environmental technology work together from the start.<\/p>

KMA combines its expertise in smoke extraction, exhaust air filtration, and heat recovery with the know-how of experienced foundry planners like Klaus Hansen, founder of ODIN Casting Solutions. This results in integrated, energy-efficient solutions for high-performance megacasting sites. <\/p>

Experience from best-practice projects, which are considered the benchmark in the industry, thus flows directly into your design. Where the extraction hood is located, how the filters are placed, and how the waste heat can be used at the site is decided in the early planning phase. <\/p>

Anyone planning megacasting is planning energy flows. The waste heat from a melting furnace is of a magnitude that can supply the entire production site \u2014 hall heating, process heat, neighboring trades. Whether this potential is tapped is not decided when buying a filter, but in the planning phase. That is why we work together with factory planners and foundry architects from the first layout sketch. <\/p>

Large machines require extensive extraction. From a clamping force of 5,000 tonnes upwards, the width and length of the hoods increase \u2014 and with them the volume of exhaust air required for reliable smoke extraction. A fume extraction hood or air curtain system captures emissions at the Gigacasting cell, whilst the energy-efficient ULTRAVENT\u00ae filter system purifies the exhaust air. <\/p>

In megacasting, we use the KMA ULTRAVENT\u00ae III in pairs: 2 x 15,000 or 2 x 20,000 m\u00b3\/h. While one device filters, the other cleans itself automatically. Extraction continues \u2014 without production interruption, without filter replacement. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

The hood must capture the smoke and keep the machine accessible.

Two-part hoods enclose the cell during operation and move apart for tool changes. Which division fits is decided by crane guidance, casting unit, and space on site. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

The dimension changes the task: larger machines, larger extraction space, more exhaust air. Added to this is the variety of casting cells and peripherals \u2014 one, two, or four spray robots, area gantries, and more \u2014 while at the same time having high requirements for the accessibility of the die casting machine for hall cranes and lifting equipment. Complex, automated casting cells in limited space: Here, experience decides which solution really fits. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t

When do you recommend an extraction hood, and when an air curtain system? <\/div><\/span>\n\t\t\t\t\t\t\t\n\t\t\t<\/path><\/svg><\/span>\n\t\t\t<\/path><\/svg><\/span>\n\t\t<\/span>\n\n\t\t\t\t\t\t<\/summary>\n\t\t\t\t

The hood is our recommendation as soon as the installation space allows it; we recommend the air curtain system if overall height, crane paths, or accessibility requirements rule out a hood. In both cases, extraction takes place directly at the source. The hood concept has been proven for many years: emissions are physically captured, the hood acts as a buffer tank that is extracted during the casting cycle and whose exhaust air is filtered \u2014 most effective extraction rate, best energy efficiency. The air curtain guides a horizontally adjustable air flow over the cell to the opposite extraction unit: working area and crane path remain free, less material and thus lower transport costs \u2014 but a higher extraction capacity. For each cell, we choose the principle where extraction rate and accessibility match. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t

How much megacasting experience does KMA have? <\/div><\/span>\n\t\t\t\t\t\t\t\n\t\t\t<\/path><\/svg><\/span>\n\t\t\t<\/path><\/svg><\/span>\n\t\t<\/span>\n\n\t\t\t\t\t\t<\/summary>\n\t\t\t\t

We know megacasting projects across the industry \u2014 KMA technology is in use today at 13 locations worldwide, with very different starting situations: casting cells with one to four robots, with and without spray gantries, machines from various DCM manufacturers, greenfield planning as well as expansion in an existing foundry. We have realized not only extraction and filtration at the die casting machine, but also exhaust air filtration and heat recovery at melting furnaces as well as the hall ventilation of entire sites \u2014 with the interfaces to the casting cell, melting furnace, ventilation technology, and fire protection. This is relevant because spraying processes, number of robots, cell layout, and furnace technology significantly change the exhaust air situation: every site needs its own design. The basis is 30 years of emission extraction on die casting machines and over 2,000 systems for the die casting industry, scaled to clamping forces beyond 5,000 tons. In research and development, we cooperate with the GTK Kassel, the Center for Lightweight Casting and Construction \u2014 we are happy to establish contact with reference sites. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Would you like to know how cell-level collection, exhaust air filtration and heat recovery can be effectively combined in large-scale casting operations?<\/p>

Then let\u2019s work together to determine which system design is best suited to your site, both technically and in terms of energy efficiency. The starting point is always the actual layout of your production hall. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t
