Metal Working Fluids
Foam control solutions to improve process efficiency, quality and safety at all stages of production
Metalworking fluids cover a wide range of oils, emulsifiers, compounds or liquids that are used to streamline metal processing and help to control such elements as temperature fluctuations, lubricate parts or reduce foaming at different stages of production. Foam is a dispersion of gas bubbles, stabilized by surfactants, in a continuous liquid phase. They occur in a wide range of industrial processes, such as Pulp & Paper manufacturing, Oil & Gas extraction, textile making, chemical processing, plastics recycling, etc. In metalworking, silicone antifoaming or defoaming solutions are essential in reducing scrap rate, extending tool lifespans and contributing to overall productivity.
Metalworking fluids come in very different forms, including mineral oils or synthetic and semi-synthetic compounds and, of course, silicone-based formulations depending on functional needs such as reducing the high-pressure on materials and foaming generated by machining or cutting fluids in the metalworking process.
Silicones have proven their efficiency as foam control agents to make manufacturing more efficient and cleaner, improve the quality of final products, reduce waste and energy consumption and facilitate recycling. They are safe for people and equipment and comply with the strictest regulations in many industries.
What are the main applications and advantages of silicone-based foam control solutions for the metalworking industry?
Silicone foam control solutions (also referred to as anti-foams or defoamers) are recognized as a material of choice for metalworking processing because they offer several advantages compared to organic or mineral substances.
Here is a summary of some of the significant benefits of silicone foam control products:
- They prevent foam from occurring upstream and reduce it more quickly and efficiently when it does occur, known as the knockdown effect. This reduces deposits during the entire process and thus speeds up production rate and improves metal parts quality.
- They are more resistant to extreme chemical conditions, high pressure and extreme temperatures, thus ensuring stability throughout the machining process.
- The quantities of silicone products needed to achieve required effects are much lower than organic or mineral-based products and offer more durable low surface tension, especially important in complex and long-lasting processes, thus reducing Total Cost of Operations (TCO).
- Silicone-based products are highly effective at low dosage and reduce waste and energy consumption.
- Silicones are inert and therefore safer for the environment and people because they reduce cavitation, spillage and other hazards.
