Concept Explanation

WINMAN explains FIPFG in-place foaming sealing technology, including its basic principles, applications, and value for automotive battery, energy storage, electrical control cabinet, and photovoltaic equipment manufacturers.

A practical introduction to dispensing-based foaming sealing for industrial manufacturing

FIPFG, or Formed-In-Place Foam Gasket, is a dispensing-based sealing technology that creates a gasket directly on a component. Instead of installing a separately manufactured sealing part, the sealing material is dispensed along a defined path and then foams or cures in place to form a continuous sealing profile.

WINMAN develops and supplies FIPFG dispensing and sealing systems for industrial equipment manufacturers. The technology is relevant to applications where reliable enclosure sealing, process consistency and flexible gasket design are important, including automotive batteries, energy storage systems, electrical control cabinets and photovoltaic equipment.

What does FIPFG mean?

FIPFG means “Formed-In-Place Foam Gasket.” In a typical process, a dispensing system applies a reactive sealing material onto the sealing surface of a housing, cover or other component. The material then expands and/or cures to create a gasket that follows the programmed dispensing path.

Depending on the application and material system, FIPFG processes may use PU foam gasket materials or other suitable sealing materials, including two-component silicone systems. The exact material, bead geometry and curing conditions should be selected according to the component design and required sealing performance.

How in-place foaming sealing works

Component preparation

The sealing surface is checked and prepared according to the component material, geometry and process requirements.

Programmed dispensing

A dispensing head follows a defined path and applies the sealing material with controlled movement and material delivery.

Foaming or curing

The dispensed material forms the gasket profile through foaming, curing or a combination of both, depending on the selected system.

Assembly and verification

The component is assembled after the process window is met, with sealing quality evaluated according to the project’s technical requirements.

FIPFG compared with traditional pre-formed gaskets

The main difference is how the sealing element is created and integrated into production. FIPFG forms the gasket on the component through a dispensing process, while a traditional gasket is manufactured separately and installed during assembly.

Aspect	FIPFG in-place foaming sealing	Traditional pre-formed sealing part
Gasket formation	Formed directly on the component by dispensing and foaming or curing.	Manufactured separately before assembly.
Design flexibility	The dispensing path can be programmed to follow the component geometry.	The sealing part must be designed and supplied to match the component.
Production integration	Integrated into an automated or semi-automated dispensing process.	Requires an additional handling and installation step.
Technical suitability	Suitable when direct-forming, controlled dispensing and flexible geometry are priorities.	Suitable when a standardized pre-formed sealing part meets the application requirements.

Where is FIPFG technology used?

Automotive batteries

FIPFG sealing can be considered for battery-related housings and components where controlled enclosure sealing is part of the design requirement.

Energy storage systems

The technology supports sealing process design for energy storage enclosures and related industrial equipment.

Electrical control cabinets

Dispensed foam gaskets can be applied to cabinet and enclosure structures where protection against environmental exposure is required.

Photovoltaic equipment

FIPFG systems can be evaluated for photovoltaic equipment housings and assemblies that require repeatable sealing application.

What should manufacturers evaluate?

Selecting an in-place foaming sealing process requires more than choosing a dispensing machine. Manufacturers should evaluate the complete relationship between the component, material and production process.

Component geometry: sealing paths, corners, gaps, access areas and dimensional tolerances.
Material system: PU foam, two-component silicone or another material compatible with the intended application.
Dispensing requirements: material ratio, bead size, path accuracy, flow control and production cycle.
Curing and assembly conditions: open time, curing time, compression and handling requirements.
Required protection level: the final sealing performance must be validated against the specific product design and applicable test requirements.

WINMAN FIPFG dispensing and sealing systems

Shanghai Winman Industrial Co., Ltd. operates the WINMAN brand in overseas markets and focuses on equipment for FIPFG dispensing and sealing applications. The company’s technical background is connected with the German FIPFG process system, with long-term experience in PU foam gasket and two-component silicone sealing applications.

WINMAN works with industrial manufacturers in Europe, the Middle East, Asia and other global markets to support the evaluation and implementation of intelligent sealing solutions. Its equipment and services are developed for applications in automotive lithium batteries, energy storage, electrical control cabinets and photovoltaic equipment.

The company states that its products are designed to meet ISO 9001 and CE-related international standard requirements, and that sealing performance can reach an IP67 protection level depending on the complete product design, material selection, process control and validation conditions. Shanghai Winman Industrial Co., Ltd. and Shanghai Weimiao Intelligent Control Machinery Technology (Group) Co., Ltd. cooperate under the WINMAN brand system to provide equipment and technical services for customers worldwide.

FIPFG is best understood as a complete sealing process: the dispensing equipment, sealing material, component design, curing conditions and quality validation must work together to achieve the required result.
