Quality Assurance & Compliance
Quality Is Not a Department — It Is Built Into Every Process
At Shenzhen Sanhe Xingye Technology Co., Ltd. (SHX), quality control is integrated into every stage of watch and watch strap manufacturing.
Since 2012, we have supplied OEM and ODM watch products to brands, distributors, and retailers across Europe, North America, Oceania, and Asia. Our quality management system is designed to ensure product consistency, regulatory compliance, and long-term reliability for every production batch.
From raw material sourcing to final shipment, every product undergoes multiple inspection procedures before leaving our facility.
ISO 9001 Certified Manufacturing System
Our manufacturing operations are conducted under an ISO 9001 certified quality management framework.
This system enables us to:
- Standardize manufacturing procedures
- Control production consistency
- Improve traceability throughout the supply chain
- Reduce defects and non-conforming products
- Maintain continuous process improvement
Every production order follows documented inspection standards and quality checkpoints to ensure repeatable manufacturing performance.
Material Verification Before Production
The quality of a watch strap begins with the materials used.
Before entering production, incoming materials are evaluated according to applicable testing requirements.
Materials commonly inspected include:
Silicone Rubber
- Tensile strength
- Tear resistance
- Elastic recovery
- Color consistency
- Skin-contact safety
FKM Fluoroelastomer
- Chemical resistance
- UV resistance
- High-temperature performance
- Aging resistance
Genuine Leather
- Surface quality inspection
- Thickness consistency
- Color fastness
- Flexibility testing
Nylon and Textile Materials
- Abrasion resistance
- Weaving consistency
- Color stability
Only materials meeting internal acceptance standards are approved for manufacturing.
In-House Quality Inspection Laboratory
Our facility is equipped with professional testing equipment used to evaluate product performance and durability.
Typical laboratory tests include:
Tensile Strength Testing
Evaluates the force required to stretch or break watch strap materials under load.
Buckle Pull Testing
Verifies the structural reliability of buckles, spring bars, and connection points.
Fatigue Testing
Simulates repeated bending and daily wearing conditions.
Salt Spray Testing
Assesses corrosion resistance of metal components and buckles.
Abrasion Testing
Measures wear resistance of strap surfaces during prolonged use.
Color Fastness Testing
Ensures material colors remain stable under friction, moisture, and environmental exposure.
Production Process Control
Quality inspections are conducted throughout manufacturing rather than only after production is completed.
Key control stages include:
IQC
Incoming Quality Control
Inspection of raw materials before production.
IPQC
In-Process Quality Control
Monitoring production parameters during manufacturing.
FQC
Final Quality Control
Inspection of completed products before packaging.
OQC
Outgoing Quality Control
Random sampling and shipment verification before dispatch.
This multi-stage inspection approach helps identify potential issues early and minimizes quality risks.
International Compliance & Product Certifications
Our products have been tested and verified according to applicable international standards.
Available certifications and reports include:
- CE Compliance
- RoHS Compliance
- SGS Testing Reports
- Antibacterial Test Reports
- Material Safety Reports
- Customer-Specific Compliance Testing
Certification availability may vary depending on product materials and destination market requirements.
Copies of relevant reports can be provided upon request.
Supplier Qualification System
Product quality begins with supplier quality.
We work with approved suppliers that meet our requirements for:
- Material consistency
- Production capability
- Traceability documentation
- Regulatory compliance
- Long-term supply stability
Supplier performance is continuously reviewed to maintain quality standards throughout the supply chain.
OEM & ODM Quality Support
For private label and custom development projects, SHX provides additional quality assurance services including:
- Pre-production sample verification
- Golden sample approval
- Mass production consistency checks
- Custom packaging inspection
- Third-party inspection support
We understand that brand reputation depends on product reliability, and we apply the same quality standards to every OEM and ODM project.
Our Commitment
Quality is not defined by certificates alone.
It is demonstrated through consistent manufacturing, reliable materials, transparent processes, and products that perform as expected in real-world use.
At SHX, our goal is simple:
To deliver watch straps and watches that meet international standards, support our customers' brands, and create long-term business partnerships built on trust.
