Trade & Market

Company slogan: Professional Watchbands Manufacturer — Since 2012.
OEM Overview:
Visual Process Overview

Concept → 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 System

We 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 Validation

Before 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 Capability

We 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 Production

R&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 Get

When 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.

R&D:

Our R&D team continuously develops new watch and strap designs based on market trends and customer feedback. We focus on both function and aesthetics to ensure our products stay competitive in the global market.

History:

The story of Shenzhen Sanhexing Technology began with the founding of Hong Kong Sanhexing Rubber & Plastic in 2008. The entrepreneurial journey was arduous, yet our founding principles remained steadfast. From the very start, we prioritized “customer interests and product quality." This commitment earned us initial market recognition in our first year, achieving sales of five million yuan and laying a solid foundation for the company's future growth.

Seizing global market opportunities, we established our physical entity in Shenzhen in 2011, embarking on a new journey. That year marked our strategic leap from precision manufacturing to independent design and R&D. Our first self-developed silicone and nylon watch straps successfully entered the market, swiftly gaining trust from customers across Europe, Asia, and the Americas. This milestone signaled Sanhexing's brand vision officially expanding internationally.

To keep pace with the market's rapid evolution, 2012 became a pivotal year for our brand's transformation. Shenzhen Sanhexing Technology Co., Ltd. was established, expanding our product portfolio to include silicone, PU, and nylon straps. More significantly, we made a forward-thinking strategic decision: to fully commit to building our own international brand, “SHA." From this point forward, Sanhexing Technology transcended its role as a mere product provider, evolving into a brand symbol embodying innovative spirit and a commitment to quality.

From Hong Kong to Shenzhen, from manufacturing to creation, Sanhexing Technology has taken each step with steadfast determination. We are grateful for the trust and companionship of the past and look forward to joining hands with you to advance toward an even broader future.
