FIPFG Formed-In-Place Foamed Gasket Sealing Solution | Meeting High-Grade Sealing Needs for NEV Battery Packs & Energy Storage Cabinets
WINMAN WM-601 is an automatic FIPFG (Formed-In-Place Foam Gasket) dispensing/foaming sealing system developed and manufactured by Shanghai Winman Industrial Co., Ltd., designed for demanding applications such as new energy vehicle (NEV) battery packs (Battery Pack), energy storage cabinets (Energy Storage Cabinet), and industrial electronic enclosures, delivering replicable and traceable sealing process capability.
Under stable operating conditions, the system can achieve a ±0.05 mm dispensing accuracy (reference value; dependent on material viscosity/path curvature/fixture positioning), and provides a process foundation to support sealing designs targeting near IP68—minimizing variation within a production-acceptable range amid “thinner boundaries, more complex contours, and higher takt times.”
In overseas customers’ search context, battery pack sealing often comes with keywords like “IP67/IP68 sealing for battery pack”, “foam gasket dispensing machine”, and “FIPFG sealing solution”. The common driver is that structures are becoming more complex, housing tolerances and assembly variation objectively exist, while products must endure vibration, temperature swings, dust, and condensation moisture over the long term.
The value of FIPFG is turning the “seal” from a prefabricated part into an “in-place formed process result,” making the sealing path programmable and repeatable—especially suitable for complex contours such as battery pack lids, housings, service ports, harness pass-throughs, and BMS/ECU enclosures.
Sealing for battery packs and energy storage cabinets is not just “able to dispense,” but being able to stay consistent across batches, shifts, and ambient temperatures as much as possible. WM-601 improves controllability at the equipment level through motion control, metering & mixing, process window management, cleaning & maintenance, and more.
| Specification / Module | Reference Capability | Meaning for Battery Packs / Energy Storage Cabinets |
|---|---|---|
| Dispensing accuracy | ±0.05 mm (reference value) | Reduces bead width/height variation, lowering local weak points and leakage risk |
| Operating speed | 0–300 mm/s adjustable | Balances takt time and stability at corners/fine beads; fits different sealing paths |
| Dual-station design | Parallel operation, alternating loading/unloading | Improves throughput with the same manpower; can reduce labor input by 40%–60% (depending on takt and layout) |
| Control system | Industrial-grade control platform (optionally integrated with German Sonderhoff-related solutions) | More stable operation and clearer alarms; beneficial for standardized replication across global plants |
| Remote diagnostics | Supports remote maintenance/parameter assistance (subject to network and permissions) | Shortens downtime handling, especially for overseas delivery projects and long-term service |
| Cleaning & maintenance | High-pressure water/air cleaning, reducing residue and clogging | Reduces maintenance frequency and manual intervention; reduces dispensing defects due to insufficient cleaning |
When evaluating an “IP68 sealing solution,” overseas customers often ask very specific questions: What is the foamed gasket height after foaming? What is the compression ratio? Can it absorb housing tolerance variation? Will rebound be insufficient after thermal cycling? Therefore, WM-601 emphasizes breaking IP rating goals into actionable process points.
Reference for common battery pack lids: bead width 3–8 mm, height after foaming 2–6 mm (depending on structure and compression). Stable width/height helps control compression ratio and reduces local over-compression or insufficiency.
For corners, hole avoidance, and locally thickened sections, FIPFG paths are programmable, reducing “break points/splices” and lowering the probability of leakage paths—especially suitable for perimeter sealing of energy storage cabinet doors and electrical enclosures.
With parameterized management of ratio, flow, path, and takt time, it is easier to establish internal CP/CPK and incoming/process audit logic; more friendly for cross-plant replication and supplier audits.
WM-601 is commonly used for products that “need water/dust protection, need complex structural sealing, and need batch consistency.” For a foreign trade website solution page, clearly describing applications can significantly improve inquiry conversion quality, because customers can quickly judge “is this the machine I need.”
Lid-to-housing gasket, service ports, harness pass-through sealing, local dust/water sealing, etc. Suitable for projects with higher IP67/IP68 targets and stronger consistency requirements.
Door perimeter sealing, compartment interface sealing, electrical enclosure sealing. For outdoor rain, wind-blown sand, and temperature swing environments, emphasizing long-term reliability and ease of maintenance.
Suitable for small housings, complex curves, and multi-hole structures; improves yield through controllable dispensing, reducing rework caused by poor sealing.
More common in scenarios sensitive to dust and condensation moisture; FIPFG can reduce issues such as wrinkles, joints, and detachment found in manual gasket strip application.
Customers buying equipment for export usually don’t just buy a machine; they buy a set of capabilities that can be implemented—from voltage adaptation and operator training to spare parts and remote support. WM-601 is designed with a “long-term stable line operation” approach, making it easier to deliver projects in Europe, Southeast Asia, the Middle East, and other markets.
An IP rating is a system-level result for the complete pack/cabinet, not determined only by the dispensing machine, but also by the material system, structural compression, housing flatness, assembly torque, etc. WM-601 provides high-consistency FIPFG forming capability to establish a process foundation for approaching an IP68 target. It is recommended to test with samples for water/dust performance and establish the corresponding process window (temperature/humidity, ratio, flow, path speed, curing time).
Typically, dual stations reduce idle time by running “dispensing and loading/unloading in parallel.” Taking a common perimeter sealing path as an example, if single-piece dispensing time is about 60–120 seconds, dual stations can often increase output by 30%–80% without adding headcount (depending on loading/unloading, leveling/curing wait, and whether vision positioning is required).
Common FIPFG materials include two-component PU foamed sealing materials, etc. Specific compatibility needs to be evaluated based on viscosity, pot life, target foaming ratio, and ambient temperature. We typically recommend customers provide the material datasheet and sample structure, verify the path and process window first, and then confirm the final configuration.
When tolerance variation is large, traditional prefabricated gasket strips are more likely to have local under-compression or over-compression. With adjustable bead width/height and local thickening strategies, FIPFG is often easier to “absorb variation.” However, final performance still requires a system evaluation with the structural design (compression, rabbet/stop features, bolt spacing, etc.).
