Product Structure
Large-Format Perimeter Seal
The 1100 × 900 mm gasket profile follows the battery-pack enclosure perimeter and creates a sealing interface between the cover and lower tray. The cross-section, flange geometry and mounting-hole pattern should be matched to the enclosure drawing and assembly-compression target.
Integrated Metal Compression Limiters
Metal compression limiters can be molded around selected mounting holes. These inserts help control the compression generated by enclosure bolts and reduce the risk of excessive rubber deformation. The limiter height, inner diameter and outer diameter should be selected according to the bolt specification, gasket cross-section and required compression level.
Custom Molded Geometry
Large-format battery enclosure seals may include asymmetrical perimeter sections, extended flanges, local reinforcements and application-specific mounting details. The gasket structure can be reviewed according to the 2D drawing, 3D model and battery-pack assembly requirements.
Applications
This 1100 × 900 mm custom EV battery pack seal can be reviewed for Roewe eRX5 plug-in hybrid battery-housing applications and similar large-format enclosures. The gasket is installed between the battery-pack cover and lower tray to help reduce the entry of water, dust and external contaminants. Integrated compression limiters can support controlled bolt compression during assembly. Similar structures can also be developed for passenger EVs, plug-in hybrid vehicles, commercial electric vehicles and Energy Storage System enclosures. The final design should be confirmed according to the housing geometry, bolt spacing, mating-surface condition, thermal-cycling environment, vibration conditions and required IP67 or IP68 validation method.
Customization Options
Custom EV battery pack seals can be developed according to 2D drawings, 3D models or physical samples. Buyers can specify the perimeter geometry, overall dimensions, cross-section, flange profile, mounting-hole pattern, compression-limiter dimensions, rubber compound, Shore A hardness, foam density, color and dimensional tolerance. Please provide the enclosure material, mating-surface geometry, bolt size, bolt spacing, target compression, operating temperature, vibration conditions, coolant exposure, ingress-protection validation requirement, required quantity and estimated annual volume. PPAP Level 3 documentation, DFM review and inspection requirements can be evaluated according to the project needs.

FAQ
What are the dimensions of this custom EV battery pack seal?
The specified large-format gasket profile measures 1100 mm in length and 900 mm in width. The cross-section, wall thickness, mounting-hole pattern and compression-limiter dimensions should be confirmed according to the battery-enclosure drawing and target compression level.
Can this gasket be used for Roewe eRX5 battery-housing applications?
The 1100 × 900 mm profile can be reviewed for Roewe eRX5 plug-in hybrid battery-housing applications. Final compatibility should be confirmed against the enclosure drawing, mounting-hole positions, cross-section, mating surfaces and bolt-compression requirements before production.
What is the purpose of metal compression limiters?
Metal compression limiters are inserts positioned around selected mounting holes. They help control compression generated by enclosure bolts and reduce excessive rubber deformation. The limiter dimensions should match the bolt specification, gasket profile and required assembly compression.
Can the gasket be designed for IP67 or IP68 requirements?
Yes. The gasket can be developed for projects with IP67 or IP68 ingress-protection requirements. Final sealing performance depends on the gasket profile, enclosure rigidity, mating-surface condition, bolt spacing, compression level and assembly method. The completed enclosure should be validated according to the required test standard.
Which material should be selected for an EV battery enclosure gasket?
EPDM can be reviewed for weather, ozone, UV, moisture and glycol-based coolant exposure. Flame-retardant silicone can be evaluated for elevated-temperature requirements. Micro-cellular EPDM or silicone foam can be considered when a more compressible interface is required to accommodate enclosure-surface variation.
What documentation is available for an automotive battery-seal project?
Documentation requirements can be reviewed according to the project. PPAP Level 3 documentation, dimensional inspection requirements, material documentation and applicable compliance reports can be evaluated after the drawing, compound specification, prototype plan and production requirements are confirmed.
