Corporate Manufacturing Profile
The Air Bag Coil (industry definition: SRS Cable Reel or Contact Assembly) serves as the electrical pivot for the driver's safety system. It prevents wire fatigue while the steering wheel rotates, connecting the Airbag Control Unit (ACU) to the igniter.
Jiaxing Richang Auto Parts, established with a total investment of 60 million RMB and a 15,000 sqm facility, is a specialized manufacturer of these safety-critical components. We differentiate ourselves through massive scale and precision: running dual shifts (22 hours/day) across our production lines, we deliver a consistent monthly output of 2.8 million Air Bag Coils, ensuring supply chain stability for our OEM partners.
Production & Validation Metrics
1. Automated FFC Fabrication
The core of an Air Bag Coil is the Flexible Flat Cable (FFC). We do not outsource this. We operate 9 sets of FFC Lamination Machines and 11 Punching/Printing Integrated Units internally. This vertical integration guarantees that the copper conductors meet exact impedance specs, preventing the "high resistance" faults that disable airbags.
2. GP10 Laboratory Accreditation
Our quality assurance is rigorously standardized. Our internal lab received SGMW (SAIC GM Wuling) GP10 Certification in July 2016. Every cable reel design undergoes:
- SRC Rotary Durability Testing: Utilizing 4 specialized rigs to execute continuous lock-to-lock cycles.
- Signal Continuity Checks: Monitored by Japanese Kikusui Testers to detect micro-interruptions (<1µs) during vibration.
3. Diverse Structural Portfolio
We engineer Air Bag Coils for every vehicle segment, tracked by precise OEM codes:
- Commercial Heavy-Duty: Roller-Type designs for BeiBen Truck (V3ET) and Dayun Auto (ST3176J), engineered for extreme rotation angles.
- Passenger & SUV: U-Type designs for Baojun (CN202S/530) and Chery, featuring compact housings and multi-channel data paths.
4. Environmental Resilience
To ensure global reliability, our coils are tested in Composite Salt Spray Chambers and High-Low Temperature Shock units (-40°C to +85°C), verifying they can withstand arctic cold and tropical humidity without insulation cracking.
OEM Application List
Our Air Bag Coils are the silent guardians in millions of vehicles, trusted by:

Trucking & Logistics
Dongfeng Shares (Tianjin/Tianlong) and Foton, where durability under high vibration is paramount.
Mass Market Passenger
SAIC GM Wuling platforms (Hongguang, Baojun series), requiring high-volume consistency.
Procurement FAQ
Q1: What is the benefit of your "Dual Shift" production?
A1: By operating our punching and lamination lines for 22 hours a day, we drastically reduce lead times. This allows us to handle urgent volume surges from Tier-1 assembly plants without bottling up the supply chain.
Q2: Can your Air Bag Coils handle ADAS signals?
A2: Yes. Our manufacturing process allows for precise control of the FFC pitch (spacing). This enables us to produce high-density 16-channel units (e.g., for Baojun CN220M) that carry sensitive data for Lane Keep Assist and Adaptive Cruise Control without interference.
Q3: How do you verify the coil won't fail in winter conditions?
A3: We use Low-Temperature Bending Testers specifically for the FFC material. This ensures the ribbon cable remains flexible and doesn't snap even when the vehicle is started in sub-zero temperatures.
Q4: Do you support aftermarket distribution?
A4: Absolutely. While we are an OEM supplier, our capacity allows us to serve reputable aftermarket distributors who demand OEM-quality replacements for popular models like the Ford Transit and Wuling series.
