Vacuum defoamer is an indispensable core process equipment in fields such as semiconductor, display panel, photovoltaic, and electronic manufacturing. Whether it is LCD screen bonding, OLED packaging, or perovskite battery preparation, bubbles are the "number one killer" that affects product yield. This article compiles the top ten famous brands and price references of vacuum defoamers, helping procurement personnel quickly understand the market landscape and select suitable equipment.
1、 What is a vacuum defoamer?
Vacuum defoamer is an industrial equipment that uses a vacuum negative pressure environment to remove bubbles inside materials. Its core principle is not complicated: after placing the material to be processed in a closed chamber and vacuuming, the bubbles rapidly expand, float up, and rupture after losing external pressure, thus being discharged from the material. For high viscosity materials or deep bubbles, the equipment will also use auxiliary methods such as heating, stirring, and centrifugal rotation to "force" the bubbles hidden deep in the material.
In precision manufacturing processes such as semiconductor packaging and LCD bonding, a single residual bubble can cause poor conductivity, bonding bubbles, appearance pinholes, and even entire batches of scrap. Therefore, although the vacuum deaerator is only a "supporting role" equipment, it directly determines the yield and cost of the production line.
2、 Classification of vacuum defoamers
According to the working principle and structure, vacuum defoamers are mainly divided into the following categories:
Vacuum box type defoamer: Place the material as a whole into a vacuum chamber for static defoaming, suitable for batch processing, with a simple structure and low cost.
High pressure defoamer: It superimposes pressure on the basis of vacuum and accelerates the discharge of bubbles through a pressure reduction cycle, suitable for processes such as LCD/OLED bonding and film coating that require extremely high levels of bubbles.
Vacuum stirring defoamer: using planetary motion with rotation and revolution, combined with vacuum pumping, to complete defoaming while stirring, suitable for high viscosity materials such as glue, silver paste, solder paste, etc.
Vacuum centrifugal defoamer: using high-speed centrifugal force to eject bubbles, suitable for defoaming materials such as glue and silver paste for syringe packaging.
3、 Application fields of vacuum defoamer
The application range of vacuum defoamers is very wide, mainly including:
Semiconductor packaging: Bubble elimination in wafer level packaging and advanced packaging.
Display panel: LCD/OLED bonding, lamination, 3D curved surface bonding and other processes.
Photovoltaic cells: Preparation process of perovskite cells and thin film cells.
Electronic manufacturing: defoaming of OCA bonding, conductive silver paste, solder paste and other materials.
Medical chemical industry: defoaming of materials such as drugs, dental mold substrates, and cosmetic substrates.

5、 Price reference for vacuum defoamer
The price range of vacuum defoamers is relatively large, mainly influenced by factors such as equipment type, chamber size, material, and automation level. The following are common reference ranges in the market:
Laboratory small vacuum defoamer: about several thousand to tens of thousands of yuan.
Vacuum stirring defoamer: about tens of thousands to over 100000 yuan.
Imported high-end mixing and defoaming machine: about 50000 to 300000 yuan.
Industrial high-pressure defoamer: Approximately tens of thousands to hundreds of thousands of yuan, customized according to chamber size and configuration.
It should be noted that the above prices are only market reference ranges, and the actual prices need to be determined based on specific models, configurations, and manufacturer quotes. It is recommended to compare multiple suppliers during procurement, with a focus on equipment safety certification and after-sales service.
6、 How to choose a vacuum defoamer?
When choosing a vacuum defoamer, it is recommended to focus on the following points:
Clarify process requirements: First determine the processing materials, cavity size, and production capacity requirements, and then choose the equipment type to avoid blindly pursuing large cavities or high configurations.
Pay attention to safety certification: The high-pressure defoamer belongs to the pressure vessel equipment category, and it is necessary to confirm whether the equipment meets the pressure vessel safety standards and whether the safety level meets the standards.
Examination of Material and Corrosion Resistance: When in contact with strong acids, alkalis, or organic solvents, corrosion-resistant materials such as stainless steel inner liners should be selected.
Evaluate the degree of automation: whether it supports program storage, parameter display, data connection to MES, etc., directly affects production efficiency and traceability.
Comparing after-sales service: Equipment is a long-term investment, and the manufacturer's installation, debugging, training, and after-sales response capabilities are crucial.
