Quality Control in China — Built Into Production, Not Added at the End

quality-control

Most quality problems don’t come from bad factories.

They come from lack of control during production.

 

Most QC companies inspect products at the end.

By then — it’s already too late.

 

At Tiroflx, quality control is built into every stage of manufacturing execution.

Not Just Inspection — Full Production Control

Our Quality Control Process — Integrated Into Production

quality control

1. Factory Validation (Before Production)

  • Physical inspection of factory before approval
  • Verification of certifications, materials, and sub-vendors
  • Only approved factories enter our supplier network

2. Pre-Production Control

  • Review of product specs, materials, and tooling before production starts
  • Approval of pre-production samples
  • Alignment on labeling, packaging, and compliance requirements

3. In-Process Quality Control

  • Ongoing inspections during active production
  • Identification and correction of issues before they escalate
  • Real-time tracking via our ERP system

4. Final Inspection

  • Full inspection of finished goods against specifications
  • Dimensional, functional, and visual quality checks
  • Compliance documentation verified

5. Pre-Shipment Verification

  • PO numbers, barcodes, quantities, and weights confirmed
  • Labeling accuracy and traceability checked
  • Final sign-off before goods leave the factory

What does it mean that we work according to European Standards?

The European regulations aim to protect the environment and human health via several strict guidelines. We apply them throughout our processes. Thus, we gained our reputation of being extremely strict with quality control. While this didn’t fall well with some factories, had the added benefit that we work with only the top quality factories and vendors in China.
