Beyond Components: An ISO13485 Manufacturing Partner
You are not buying a part. You are auditing a process. Quankang operates a 120,000+ sq ft smart factory in Dongguan, China, specifically equipped to handle compliance demands of US and European markets. We do not assemble in a warehouse. We engineer in a certified environment.
Verified Manufacturing Capabilities
- EMC Laboratory (On-site): Pre-compliance testing for FCC and CE standards saves you 4-6 weeks of certification delays.
- AOI + ICT Inspection: 100% automated optical inspection on every PCB. Zero defects is the standard.
- MES + SAP Traceability: Every component is tracked. If a batch ever needs recall, we know exactly which units shipped to your Boston warehouse.
Production Volume: We produce tens of millions of units annually. Your clinical trial needs (500 units) and mass production needs (500,000 units) come from the same stable process.
Solving Supply Chain Pain Points for ODMs and Distributors
Different buyers face different challenges. Here is how Quankang addresses each one.
For Medical Equipment Manufacturers (ODMs)
The Pain Point: Switching to a new power supplier requires full re-certification (IEC60601, UL, CE). This process costs tens of thousands of dollars and takes months. Also, when a supplier faces stock shortages, your entire production line for ventilators, infusion pumps, or patient monitors shuts down.
How Quankang Solves It: We provide full certification dossiers with every sample. Your compliance team gets TUV and Intertek reports before placing a purchase order. No surprise re-testing costs. Our multi-year contracts guarantee buffer stock. If we face a raw material shortage, we will notify you 90 days in advance with alternative options.
For Industrial and Communications Equipment Manufacturers
The Pain Point: Your power adapters fail EMC testing during final product validation. This delays your market launch by 4 to 8 weeks. You also face batch inconsistency – one lot works perfectly, the next lot has a 5 to 8 percent rework rate due to voltage fluctuations or noise.
How Quankang Solves It: Every batch undergoes 100 percent AOI inspection and ICT testing before leaving our factory. Our on-site EMC laboratory pre-scans every new design to FCC and CE standards. We share the pre-compliance report with you. This increases your first-pass EMC success rate. Across 10,000+ OEM projects, our first-pass EMC compliance rate is 98.3 percent.
For Distributors
The Pain Point: You resell power adapters to your customers. Some suppliers provide grey market products with inaccessible or fake certificates. When your customer faces an audit or a device failure, you are held accountable. You also struggle with unstable supply – your small suppliers cannot handle large purchase orders.
How Quankang Solves It: Every certificate is active and verifiable via TUV and Intertek certification numbers. We provide PDF copies and portal access. You can share these directly with your customers. Our ISO13485 factory produces tens of millions of units annually. We handle large volume orders (100,000+ units) with consistent lead times. No more scrambling for stock.
Key Benefits for All Buyers:
- Reduce BOM Cost: We design cost out without cutting safety corners.
- Audit-Proof Paperwork: Full legal traceability for FDA(USA) and MDR (EU) submissions.
- 35-Year Lifespan Support: We do not discontinue models. Your device stays certified.
