Manufacturing & Engineering Capabilities
We support EV programs with a manufacturing approach focused on repeatability, material performance and dimensional control. From compound selection to tooling strategy, we help you reach durability and sealing targets without over-design.
Material Options
- EPDM (−40°C to +150°C) — weathering resistance, water/steam sealing, long-life outdoor exposure. Ideal for battery enclosure gaskets exposed to road splash and UV.
- Silicone VMQ (−55°C to +200°C) — wide temperature range, excellent compression set. Used in battery pack gaskets where thermal cycling is severe.
- Fluorosilicone FVMQ (−55°C to +175°C) — combines silicone flexibility with fuel/oil resistance. Suited for seals near coolant lines and drivetrain interfaces.
- FKM / Viton (−20°C to +200°C) — superior chemical resistance to oils, fuels, and aggressive coolants. Used in high-temperature EV motor and inverter sealing.
- HNBR (−30°C to +150°C) — high mechanical strength with oil and ozone resistance. Excellent for dynamic seals and NVH components.
- NBR / Nitrile (−40°C to +120°C) — cost-effective oil resistance for general-purpose EV sealing applications.
What We Optimize For
- Low compression set — stable sealing force over thousands of thermal cycles (−40°C to +150°C range)
- Dimensional consistency — tight tolerances for groove-controlled assemblies and automated line fitment
- IP67/IP68 sealing — gasket geometry, compression ratio, and surface finish optimized for ingress protection targets
- Media resistance — validated against common EV fluids: glycol coolants, brake fluids, salt spray, road splash
- Flame retardancy — UL 94 V-0 rated silicone compounds available for battery compartment applications
- Production scalability — prototype (50 pcs) → pilot (1,000 pcs) → series production (100,000+ pcs/year)
Tooling & Process
- Compression molding — for gaskets, pads, dampers, and large-profile seals
- Transfer molding — for complex geometries and rubber-to-metal bonded parts
- Injection molding — for high-volume connector seals, wire seals, and precision parts
- In-house CNC & EDM tool room — tooling design, manufacture, and modification under one roof

Quick answers for EV rubber components, sealing targets, materials and sourcing
We manufacture EV rubber components such as battery pack gaskets and seals, connector seals, wire seals, grommets, O-rings and custom rings, bellows/boots, caps/plugs, and NVH parts like anti-vibration mounts and bushings. Part selection depends on your subsystem and mating design.
Yes — sealing performance depends on gasket geometry, controlled compression, clamp design, surface finish, and the chosen elastomer. Share your target IP rating, groove details and environment so we can recommend an appropriate material and profile.
Common elastomers include EPDM (weathering and water resistance), silicone (VMQ) and fluorosilicone (FVMQ) for temperature extremes, and FKM/HNBR/NBR for media resistance. Final selection depends on temperature range, coolant/oil/salt exposure, and compression set targets.
Yes. Share your 2D/3D drawing, mating part details, tolerances, and functional requirements. We can propose tooling strategy, compound options and manufacturing feasibility for prototypes and series production.
Send the drawing (or sample photos with dimensions), expected monthly volumes, target material (if known), temperature range, media exposure (coolant/oils/salt spray), and target sealing requirement (e.g., IP rating). If you have a mating groove drawing, include it.
