III Fume Extraction Systems in Die Casting

Maintaining clean air in die casting operations protects workers from harmful fumes and vapors, enhances production efficiency, and ensures compliance with occupational health and safety regulations.

Fumes, vapors, and smoke generated during die casting processes pose serious health risks if not properly controlled. Without an effective fume and vapor extraction system, these hazardous pollutants spread throughout the workspace, creating an unsafe atmosphere for operators and compromising overall workplace safety.

Inadequate ventilation not only endangers worker health but also increases the risk of buildup and corrosion on machine components, shortening equipment lifespan, reducing productivity, and raising maintenance costs. Moreover, in today’s safety-conscious work environments, companies lacking proper filtration systems may struggle to retain skilled labor and face legal consequences.

In contrast, businesses that invest in advanced fume and vapor extraction systems tailored for die casting applications create a safer and healthier working environment, improve employee satisfaction, and enable continuous, sustainable production operations.

III Why Clean Air?

HEALTH RISKS

Fumes, vapors, and soot particles released during die casting operations pose significant health hazards. If these pollutants are not effectively removed from the workspace, they create an unsafe environment that endangers worker health. Poor air quality can lead to reduced production efficiency, frequent equipment failures, and decreased employee satisfaction. Companies that ignore these risks may face legal penalties and struggle to retain qualified personnel. In contrast, businesses that prioritize workplace safety achieve higher productivity, long-term cost advantages, and sustainable operational success.

PRODUCTION LOSS

Fumes, vapors, and soot particles generated during die casting processes can negatively impact factory efficiency if not properly controlled. These contaminants may infiltrate machinery and electrical panels, leading to malfunctions, unplanned downtimes, and reduced performance. Additionally, residue buildup on equipment and products increases cleaning and maintenance costs. Skilled workers prefer safe and clean-air environments, and often consider these conditions when making career decisions.

III What is Die Casting?

Die casting is a metal forming process in which molten metal is injected into steel molds (dies) under high pressure. This method is ideal for the mass production of precise components made from low-melting-point metals such as aluminum, zinc, and magnesium. The molds allow for the repeated production of complex geometries with consistent accuracy. Widely used in industries like automotive, white goods, aerospace, and electronics, die casting enhances both production speed and product quality.

However, the high temperatures involved in the die casting process generate various pollutants such as metal vapor, oil mist, soot, and fine particles. These contaminants not only pose serious health risks to workers but also accumulate on production equipment, leading to malfunctions and increased maintenance requirements. Therefore, an effective fume and vapor extraction system must be integrated into the process, with continuous monitoring of indoor air quality. Such systems play a critical role in enhancing workplace safety and achieving long-term sustainability in production.

Sliding Hood

Sliding hoods play a critical role in the efficient operation of die casting machines and the effective capture of smoke, fumes, and vapors released during the process. To learn more about automatically opening and closing sliding hoods, please contact your Bomaksan Sales Representative.

III How to Collect Die Casting Fume?

In the die casting process, special mold release agents are applied to the mold before molten metal is injected under high pressure. These chemicals ensure that the finished part can be removed smoothly and without damage. Typically sprayed onto the mold surface prior to casting, they facilitate clean separation after solidification. However, when these agents come into contact with the high temperatures of the molten metal, they produce significant amounts of smoke, fumes, and oily vapors. To maintain air quality and minimize occupational health risks, these emissions must be effectively extracted from the environment. At this point, properly designed ventilation hoods play a critical role.

Vapors and fumes generated during die casting processes can rapidly rise and spread throughout the workspace due to high temperatures. Therefore, hood systems must be positioned directly above the casting machines to effectively capture airborne pollutants. However, since product removal from molds often requires cranes or transport systems, these hoods need to be designed with mobility and flexibility in mind. Bomaksan offers specially engineered extraction solutions for such demanding conditions, ensuring operator safety while supporting production efficiency.

HOW TO CHOOSE THE RIGHT SYSTEM?

In die casting processes, mold release agents used often contain chemicals that, upon contact with molten metal, generate dense and oily fumes. When these fumes are filtered using conventional dry filters or standard oil mist filters, the filter pores clog quickly, significantly reducing system performance and increasing the risk of fire. Clogged filters also lead to frequent maintenance, longer downtimes, and high replacement costs.

At Bomaksan, we offer a safer, more efficient, and long-lasting filtration solution through our partnership with German-based KMA, a leading manufacturer of electrostatic filters with automatic washing functionality. These advanced systems ensure uninterrupted production with minimal maintenance, while maximizing ventilation efficiency. Washable electrostatic filter technology not only improves indoor air quality but also reduces maintenance expenses, accelerating return on investment. You protect both the health of your employees and your surrounding environment while safeguarding production efficiency.
