As an important part of manufacturing industry, metal processing industry covers casting, forging, welding, cutting and many other links. During production, a lot of foam is often generated due to liquid metal flow, coolant use, lubricant addition, etc. These foam not only affect the processing quality, but also may cause equipment failures and increase production costs. Therefore, the metal processing industry urgently needs efficient and stable defoamers. At the same time, the increasingly strict environmental regulations require defoamers not only to have excellent defoaming performance, but also to meet environmental standards.

There are various types of defoamers in the metal processing industry, mainly including organic silicon type, mineral oil type, polyether type, and composite type. Various defoamers have their own characteristics in terms of temperature resistance, acid and alkali resistance, solubility, etc. For example, organic silicon defoamers have excellent high temperature resistance and chemical stability, making them suitable for high-temperature melting processes; Mineral oil based defoamers have good lubricity and dispersibility, and are suitable for coolant and lubricant systems.

Defoamer for metal processing industry can quickly merge, break and release gas by destroying the elasticity of foam wall film, so as to achieve defoaming effect. Its advantage is that it can quickly respond to foam problems, effectively inhibit the regeneration of foam, and do not affect other properties of metalworking fluid. In addition, high-quality defoamers can improve processing efficiency, reduce scrap rates, and lower production costs.

When selecting defoamers for the metal processing industry, factors such as defoaming efficiency, foam suppression durability, compatibility with metalworking fluids, and environmental friendliness should be comprehensively considered. At the same time, customized selection should be made based on specific processing techniques, equipment requirements, and working environments. Laboratory testing and practical application verification are important means to ensure the selection of suitable defoamers.

A large foundry enterprise found that the problem of foam was difficult to solve completely when using traditional defoamer, which led to frequent surface defects of castings. By introducing a new compound defoamer, the enterprise successfully reduced the production of foam, improved the surface quality of castings, and reduced the rejection rate and production costs. This case fully demonstrates the importance of selecting suitable defoamers to enhance the competitiveness of metal processing enterprises.

With the continuous development of the metal processing industry, the demand for defoamers will become more diversified and personalized. In the future, defoamers in the metal processing industry will develop towards higher efficiency, environmental friendliness, and intelligence. By applying new materials and technologies, develop defoamer products with superior performance to meet the needs of different metal processing enterprises.
