DONGGUAN, CHINA – In the world of automotive audio manufacturing, "High Quality" is not just a slogan; it is a measurable feat of precision engineering.
Recently, Erisson Audio (SEAO) released its latest quality performance data, setting a new industry benchmark with a consistent 99.98% product pass rate. This achievement is built upon our "zero-compromise" quality management protocols, strictly certified under IATF 16949, ISO 9001:2015, and ISO 14001:2015 international standards.
1. The Core Strength: 32 Control Points & 12 Rounds of 100% Inspection
To ensure that every speaker delivered to our global clients is in peak condition, we have deconstructed our entire production process into 32 critical Quality Control (QC) points. Most notably, we mandate 12 stages of 100% full-unit inspection.
This means every single speaker—from individual components to the finished product—undergoes 12 rounds of exhaustive screening. We do not rely on mere statistical sampling; we audit every unit to ensure not a single flaw escapes the facility.
2. Detailed Breakdown: Precision Quality Control (The Coaxial Benchmark)
Our 12-stage inspection covers every link in the supply chain, using our professional coaxial series as the standard:
IQC (Incoming Quality Control): We strictly enforce sampling standards at the source to prevent any substandard raw materials from entering our warehouse.
The "Visual Catchers" on the Line: During assembly, multiple 100% visual inspection points are set to capture cosmetic flaws, adhesive volume issues, magnet centering, and soft-part alignment.
Rigorous Acoustic Performance Testing:
Woofer/Midrange Lines: 100% polarity testing and manual listening checks to ensure zero unusual sound or vibration.
Tweeter Line: Independent 100% acoustic testing and polarity verification for high-frequency drivers.
Final Assembly Testing: A comprehensive 100% sound check after total assembly to verify frequency response and overall tonal harmony.
The Final Barrier: Before and after the packaging line, we perform a terminal 100% sound audit and verify that all packaging accessories are complete.
3. Ultimate Validation: OQC Audit & Golden Sample Verification
Once products are palletized, our OQC (Outbound Quality Control) team performs a deep-dive inspection.
Based on the "Golden Sample" standard, they randomly audit 2-4 boxes per pallet, verifying aesthetics, acoustic parameters, and packaging contents to ensure mass production matches the approved prototype exactly.
4. The "Everyone is QC" Culture
At Erisson, quality is a shared mission, not just a department.
Beyond our systematic inspections, our QC Managers, PE Engineers, Production Managers, Lead Engineers, and even Sales Directors perform random spot checks at any time during production. This multi-dimensional, cross-departmental oversight forms the foundation of Erisson’s quality promise to our global partners.
Twenty years of manufacturing heritage have taught us that absolute trust is built on an absolute reverence for the process. A 99.98% pass rate is not our finish line, but a new starting point for delivering continuous value to your brand.
