QUALITY

Quality Integration in Every Process

Unlike relying solely on final inspection, we implement an integrated quality control system where inspection is embedded in each step — materials, tooling, assembly, and packaging.

Standardized Process

Comprehensive implementation of standardized operating procedures (SOps)
Process integration

Inspection checkpoints embedded throughout: raw materials ➝ semi-finished ➝ finished ➝ shipment
Record traceability

Batch-by-batch documentation with 100% traceability
Internal Review

Internal audits and scheduled quality reviews
Training Assessment

Position-specific training and skill certification for all operators

Manufacturing + R&D Integration

Engineering for Manufacturability

Our R&D and manufacturing teams work in sync — from prototype feasibility to mold optimization and production process design — ensuring that your custom product can be scaled efficiently and accurately.

3D structural modeling with manufacturability assessment
Rapid prototyping based on client drawings with mass production optimization suggestions
In-house mold development to reduce prototyping and initial tooling costs
Cross-functional testing and failure mode prediction mechanisms

Certifications & Production Standards

Built to Global Compliance

All manufacturing follows ISO9001 quality management system, and our factory is certified by BSCI (EU social compliance). Product testing and documentation fully support CE, ROHS, EN817, EN1112 standards.
