Metal Working Fluid Defoamer – High-Performance Foam Control for Precision Manufacturing

In metalworking operations—cutting, grinding, milling, or forming—foam is more than a nuisance. It quietly reduces efficiency, increases costs, and disrupts production schedules. When foam builds up, several common problems appear:
Reduced tank capacity: Foam occupies valuable space in mixing tanks, forcing you to run smaller batches than your equipment allows.
Slower filling speeds: Filling lines must be slowed down to prevent overflow, leading to missed deadlines and higher labor costs.
Equipment downtime: Excessive foam can interfere with sensors and pumps, causing unexpected maintenance and production interruptions.
Reliable foam control is therefore essential for stable production, longer tool life, and consistent product quality.

Our specialized metal working fluid defoamers are engineered for the demanding conditions of modern machining. With more than 17 years of defoamer customization experience, we offer targeted solutions that deliver rapid knockdown, long-lasting suppression, and excellent compatibility with saponified oils, lubricants, and antifreeze formulations.
Key Product Series
Saponified Oil Defoamer
Designed for severe foaming systems generated during metalworking fluid production and metal processing. It offers excellent heat resistance and strong acid/alkali resistance, with no floating oil or oil separation, performing reliably across a wide temperature range.
Lubricant Defoamer
Provides superior compatibility with emulsified oils compared with conventional market defoamers. It mixes uniformly with all types of lubricating oils, shows no floating, and has strong anti-shear performance that prevents oil separation when blended with saponified oils—helping keep machine-tool surfaces clean.
Antifreeze Defoamer

Delivers outstanding heat resistance and acid/alkali resistance with no floating or oil separation. Suitable for severe foaming systems over a broad temperature range. It does not affect product transparency, offers good compatibility, and remains free of sedimentation even after long-term storage.

These defoamers are designed for easy incorporation into existing metalworking fluid formulations. They help maintain system cleanliness, improve heat transfer, reduce maintenance frequency, and support higher production efficiency.
