FIPFG In-Place Foaming Sealing Technology for Industrial Equipment
FIPFG is a point-to-point sealing process that applies foaming gasket material directly onto a component. For industrial equipment manufacturers, this approach provides a flexible way to create customized sealing solutions for enclosures, covers, panels, and other components that require reliable protection against environmental exposure.
WINMAN, operated in overseas markets by Shanghai Winman Industrial Co., Ltd., develops and supplies dispensing equipment and intelligent sealing solutions based on FIPFG technology. The company supports manufacturers in automotive batteries, energy storage systems, electrical control cabinets, photovoltaic equipment, and related industrial applications.
What FIPFG Means
FIPFG stands for Formed-In-Place Foam Gasket, commonly described as in-place foaming sealing. Unlike a gasket that is manufactured separately and then installed on a component, the sealing material is dispensed directly along the required sealing path. It then forms a continuous foamed gasket in the intended position.
This method is particularly suitable when sealing geometry, component dimensions, or production requirements call for a customized gasket profile. The process can be integrated into an automated dispensing workflow, helping manufacturers establish a consistent relationship between the component design, material application, and sealing operation.
How the In-Place Foaming Sealing Process Works
- Component and sealing path definition: The sealing area is determined according to the component structure, contact surface, and application requirements.
- Material preparation: PU foaming gasket material is prepared for controlled dispensing. WINMAN also has technical experience in two-component silicone sealing applications.
- Point-to-point dispensing: The sealing material is applied directly along the specified path by a dispensing system.
- Foaming and formation: The applied material expands and forms a gasket in place, following the designed sealing route.
- Inspection and validation: The finished seal is evaluated according to the component design, process requirements, and target protection performance.
Why Manufacturers Use FIPFG Technology
Customized sealing paths
The gasket is formed directly on the component, supporting sealing paths designed around specific enclosure or panel geometries.
Integrated production process
Dispensing, foaming, and process control can be organized as part of an equipment-based manufacturing workflow.
Adaptation to industrial applications
FIPFG can be considered for industrial components where environmental protection and a repeatable sealing operation are important.
FIPFG and Traditional Pre-Formed Gaskets
Both in-place foaming and pre-formed gaskets can be appropriate depending on the component design and manufacturing process. The key difference is how the sealing element is produced and installed.
| Consideration | FIPFG in-place foaming sealing | Traditional pre-formed gasket |
|---|---|---|
| Gasket formation | Formed directly on the component after dispensing | Manufactured separately before installation |
| Sealing geometry | Can follow a defined, customized dispensing path | Depends on the shape and dimensional accuracy of the supplied gasket |
| Process organization | Uses dispensing equipment to apply the material in place | Requires a separate gasket handling and installation process |
Typical Industrial Application Areas
WINMAN FIPFG dispensing and sealing solutions are intended for manufacturers that need controlled application of foaming gasket material on industrial components. Relevant application areas include:
- Automotive batteries:
Sealing-related processes for battery housings and associated components. - Energy storage systems:
In-place sealing applications for storage equipment and enclosures. - Electrical control cabinets:
Gasket formation for cabinet doors, covers, and enclosure interfaces. - Photovoltaic equipment:
Sealing processes for equipment exposed to demanding industrial environments.
Selecting a Suitable FIPFG Solution
The appropriate equipment configuration depends on factors such as the component geometry, sealing path, material system, production volume, automation requirements, and target protection performance. A practical evaluation should consider both the dispensing process and the final seal.
Where a project targets an enclosure protection level such as IP67, the complete design, material selection, dispensing parameters, assembly conditions, and validation procedure should be assessed together. The achievable result depends on the specific application and must be confirmed through project testing.
WINMAN as an Industrial Sealing Equipment Partner
Shanghai Winman Industrial Co., Ltd. has focused on FIPFG dispensing and sealing systems, with technical experience in PU foaming gaskets and two-component silicone sealing. The company’s technology is connected with the European FIPFG process tradition and is developed for practical industrial manufacturing requirements.
WINMAN products are designed to support intelligent sealing solutions for international B2B customers. The company’s products are developed in accordance with applicable ISO9001 and CE-related requirements, and its solutions have been supplied to customers in more than 100 countries and regions. Project suitability, process parameters, and final sealing performance should be confirmed according to each customer’s component and production conditions.
For manufacturers evaluating in-place foaming sealing, the most effective starting point is a clear review of the component, sealing route, material, and required production process. This allows the FIPFG solution to be matched with the actual technical and manufacturing needs of the project.
