Company slogan: Professional Watchbands Manufacturer — Since 2012. OEM Overview: Visual Process OverviewConcept → Engineering → Material Validation → Prototyping → Tooling → Pre-Production Testing → Mass Production → Quality Control → Delivery
OEM Is Not Customization. It’s Controlled Manufacturing.Many suppliers describe OEM as “logo printing + color changes."
That’s not OEM. That’s surface-level modification.Our OEM capability starts deeper—at the engineering, structure, and production feasibility level.
We don’t just produce your design.
We validate whether your design can survive real-world use, mass production, and long-term consistency.From Concept to Production: A Structured Development SystemWe support the full development cycle, not just isolated steps.
1. Concept Translation- Convert sketches, references, or samples into manufacturable designs
- Evaluate feasibility based on material behavior and tooling limitations
- Recommend structural adjustments to improve durability and assembly
2. 3D Design and Engineering- CAD modeling for strap structure, link systems, and connection points
- Tolerance control for mass production consistency
- Functional simulation for stress, flexibility, and wear
3. Material Selection and Testing- Match materials to use-case: silicone, FKM, leather, stainless steel, TPU
- Evaluate skin contact performance, flexibility, and environmental resistance
- Recommend cost-performance balance based on target market
Material choice directly impacts durability, comfort, and perceived value, which is why professional OEM suppliers treat it as a core R&D function rather than a simple option list
4. Rapid Prototyping- Sample development within controlled timelines
- Multiple iterations based on real feedback
- Adjustment of structure, finishing, and assembly details
Typical industry sample cycles range from a few days to weeks depending on complexity
5. Tooling and Process Development- Mold design for silicone and TPU straps
- CNC machining and stamping for metal components
- Stitching and edge-finishing systems for leather
Each product type requires a different manufacturing logic.
We align tooling with product positioning, not just production speed.
6. Pre-Production ValidationBefore mass production, we test:
- Structural integrity under repeated movement
- Surface durability (coating, brushing, polishing)
- Assembly consistency across batches
This step prevents the most common OEM failure:
“perfect sample, inconsistent bulk order."R&D That Solves Real Problems (Not Just Design Trends)Our R&D focus is not limited to appearance.
We work on issues that directly affect end users and brand reputation:- Skin irritation caused by material or finishing
- Strap deformation after long-term use
- Clasp failure or poor fit tolerance
- Sweat and environmental degradation
This approach reflects how advanced manufacturers integrate R&D with production systems rather than treating them as separate functions
Cross-Material Development CapabilityWe don’t specialize in one material.
We engineer across multiple categories:- Silicone and FKM for sports and performance straps
- Stainless steel for durability and premium positioning
- Leather for traditional and high-end applications
- Nylon and TPU for lightweight and functional designs
This allows us to recommend the right material for your market, not just the one we produce.
Customization Depth (Beyond Basic OEM)We support multi-layer customization:
- Structural customization (link design, thickness, flexibility)
- Functional customization (quick-release, clasp systems, adapters)
- Surface customization (finishing, coating, texture)
- Brand identity (logo integration, packaging, visual consistency)
A complete watch strap is a system of components—strap, buckle, interface—and each can be engineered for your brand
Built for Scalable ProductionR&D is only valuable if it can be reproduced at scale.
Our system ensures:
- Design-to-production consistency
- Stable quality across large orders
- Controlled lead times and repeatability
This is what separates a design supplier from a manufacturing partner.
What You Actually GetWhen working with us, you are not buying a product.
You are building a repeatable, scalable SKU with controlled quality.We help you:
- Reduce development risk
- Shorten time to market
- Maintain consistency across batches
- Align product design with your target price and positioning
Production Line: SHX has a well-organized production line equipped with advanced equipment and experienced workers. Each process — from raw material selection to assembly and packaging — follows strict quality control standards. We ensure stable output, reliable quality, and timely delivery to meet the needs of global clients.
About quality management: Quality Assurance & ComplianceQuality Is Not a Department — It Is Built Into Every ProcessAt 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 SystemOur 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 ProductionThe 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 LaboratoryOur facility is equipped with professional testing equipment used to evaluate product performance and durability.
Typical laboratory tests include:
Tensile Strength TestingEvaluates the force required to stretch or break watch strap materials under load.
Buckle Pull TestingVerifies the structural reliability of buckles, spring bars, and connection points.
Fatigue TestingSimulates repeated bending and daily wearing conditions.
Salt Spray TestingAssesses corrosion resistance of metal components and buckles.
Abrasion TestingMeasures wear resistance of strap surfaces during prolonged use.
Color Fastness TestingEnsures material colors remain stable under friction, moisture, and environmental exposure.
Production Process ControlQuality inspections are conducted throughout manufacturing rather than only after production is completed.
Key control stages include:
IQCIncoming Quality Control
Inspection of raw materials before production.
IPQCIn-Process Quality Control
Monitoring production parameters during manufacturing.
FQCFinal Quality Control
Inspection of completed products before packaging.
OQCOutgoing Quality Control
Random sampling and shipment verification before dispatch.
This multi-stage inspection approach helps identify potential issues early and minimizes quality risks.
