Industry Requirements & Challenges

Extreme environment adaptability
Automotive electronic components must operate stably from -40°C to 150°C under high humidity, salt spray, UV and severe vibration (15g+). Sealing and bonding of ADAS sensors, cameras and radar systems must reach IP67/IP69K for heavy rain, wading and high-pressure washing.
Automotive-grade quality standards
The automotive industry requires a zero-defect philosophy with PPM-level defect rates, compliant with IATF 16949 and AEC-Q standards. Battery-pack sealing must pass million-cycle testing for 15+ years of service life.
Optical and electrical performance
Camera lens assembly requires ±0.01mm dispensing accuracy to avoid adhesive overflow onto optical lenses. Automotive chip packaging requires precise underfill control to avoid bubbles and voids for long-term electrical reliability.
Fast response and flexible production
Rapid product iteration requires fast changeover and small-batch, high-mix production with high automation and 100% full inspection for OEM audits.

Core Technology Solutions

Automotive-grade precision dispensing
0.01ml-10ml wide-range control with ±0.5% repeatability, adapting to polyurethane, silicone, epoxy and hot-melt adhesives (1-500,000 cPs). High-temperature-resistant jet valves, gear pumps and screw pumps cover diverse materials with 316L stainless steel for long-term stability.
High-reliability sealing technology
3D trajectory planning for complex sealing paths with circular, rectangular and irregular cavities. Closed-loop pressure control plus vision guidance ensures ±5% adhesive-width and height consistency, with sealing that withstands -40°C to 150°C and 10+ years of aging.
Intelligent quality control
Integrated high-resolution vision detects adhesive width, height, offset, bubbles and overflow in real time for automatic OK/NG judgment with PPM-level defect rates.
Flexible production platform
Modular design supports fast changeover (15 minutes or less) for multi-model switching. PLC, motion controller and vision integration support MES/ERP connectivity with MTBF of at least 10,000 hours.

Core Application Products

ADAS sensor sealing and waterproofing
Provides high-reliability sealing for cameras, millimeter-wave radar, LiDAR and ultrasonic radar, reaching IP67/IP69K protection against rain, sand and high-pressure washing for all-climate stability.
Automotive camera lens assembly
Provides high-precision lens bonding for front-view, surround-view and DMS cameras with ±0.01mm accuracy, preventing adhesive overflow onto optical lenses and ensuring optical-axis precision.
Power battery pack sealing
Provides cover sealing, module bonding and thermal potting for new-energy battery packs, forming flexible sealing layers resistant to electrolyte corrosion for IP67 protection and 50%+ efficiency improvement.
Automotive chip packaging (Underfill)
Provides underfill and glob-top solutions for automotive MCU, power chips and IGBT modules, eliminating voids and meeting AEC-Q100 Grade 0 requirements for long-term reliability.
Automotive connector and ECU sealing
Provides waterproof, dustproof and salt-spray-resistant sealing and potting for high-voltage connectors, harnesses and ECU controllers, passing 1000-hour salt-spray and temperature-cycling tests.

Customer Value

Product reliability assurance
Automotive-grade sealing ensures long-term stability in extreme environments, reducing warranty costs. ADAS sensor protection reaches IP69K and battery-pack sealing passes million-cycle testing for 15+ years of service life.
Production efficiency improvement
Automated dispensing replaces manual coating, improving efficiency 3-5x with fast changeover (15 minutes or less) for multi-model flexible production and 100% full inspection.
Cost optimization
Precise fluid control reduces adhesive waste by 15-25%, and automation cuts labor by over 60% for a 20-30% reduction in overall production cost.
Accelerated compliance
Complete IATF 16949 and AEC-Q test reports and documentation help customers pass PPAP audits quickly, shortening new-product introduction cycles by 6-12 months.
