In metalworking workshops, excessive cutting fluid foam is a common and troublesome problem. Too much foam not only overflows from the tank, causing waste and mess, but also seriously affects machining results. Foam covering workpieces and tools leads to uneven cooling and lubrication, which may cause reduced surface finish, dimensional deviation, and even abnormal tool wear. In addition, foam accelerates the deterioration of cutting fluid and may hinder the normal operation of the filtration system.
The market urgently needs a solution that suppresses foam quickly and durably without affecting the original performance of the cutting fluid. Chemi Tech deeply understands this pain point and, drawing on expertise in surface chemistry, has developed a series of high-efficiency cutting fluid defoamers.
Our solution is not simply an additive but a systematic approach to foam problems. Step one is problem diagnosis: our technical staff analyze the cause of your foaming, whether air is drawn in by the circulating pump, there are water quality issues, or the cutting fluid formulation itself foams easily. Step two is model matching: for water-based semi-synthetic, fully synthetic, or emulsion cutting fluids, we offer dedicated defoamer products to ensure compatibility and long-lasting performance. Step three is addition guidance: we provide precise dosage ratios and dosing point recommendations, usually only an extremely low addition (0.1%-0.5%) is needed to spread rapidly through the circulation system and break the foam film structure. Step four is effect tracking: we focus on long-term foam suppression to ensure the product remains stable under mechanical shear and high temperatures.
For example, a customer specializing in precision machining of aluminum alloy parts found that, after using a certain brand of cutting fluid, its high-speed machining centers kept producing thick foam in the tank, with frequent overflow, a heavy cleaning burden on workers, and doubts about machined surface quality. After adopting the defoamer matched by Chemi Tech, foam volume was reduced by more than 95% after just one shift of circulation. In subsequent continuous use, foam was controlled over the long term, cutting fluid consumption decreased, workpieces became easier to clean, the workshop environment improved greatly, and the customer regained confidence in machining quality stability.
Choosing Chemi Tech defoamers means choosing deep assurance for your production process. We are committed to helping customers eliminate foam interference, allowing cutting fluid to work reliably, and making the metalworking process smoother, more economical, and more controllable.
