Process & Manufacturing Insights
This product is manufactured using state-of-the-art Plastic Injection Molding technology. At Sunmy Hardware, we utilize high-precision injection molding machines and custom-engineered steel molds to ensure unparalleled product consistency and structural integrity.
Our process begins with selecting premium-grade, hypoallergenic, food-safe silicone raw material. This material is fed into the heated injection unit, plasticized, and then injected under high pressure into the mold cavity. The intricate multi-hole array is formed precisely by the mold's core pins, ensuring clean edges and uniform venting across every single strap.
Unlike compression molding, our injection molding process ensures:
📐
Superior Dimensional Stability
Tighter tolerances, crucial for the watch lug attachment points.
✨
Flawless, Smooth Finish
Free of flash or burrs, enhancing wearer comfort.
🔬
Material Homogeneity
Providing consistent elasticity and tensile strength throughout the entire strap.
🏭
High-Volume Efficiency
Allowing us to meet large-scale orders with consistent quality.

Main Features & Advantages
-
Ultimate Breathability & Sweatproof Design The extensive network of perforated air vents ensures continuous airflow to the wrist. This drastically improves comfort during sports, exercise, or hot weather by preventing sweat accumulation and skin irritation.
-
Premium Silicone Material Our soft-touch silicone is flexible, highly durable, waterproof, and resistant to environmental wear. It is also hypoallergenic, making it safe for prolonged skin contact.
-
Secure & Robust Hardware Equipped with a thick, brushed stainless steel tang buckle and reinforced silicone keepers (loops), this strap guarantees a secure fit even during rigorous activity.
-
Ergonomic Comfort The strap is designed with pre-curved geometry and balanced elasticity, allowing it to contour perfectly to the wrist without pinching or restriction.
-
Full OEM/ODM Customization — Our Core Strength While we offer standard specifications, we are fully equipped to develop and manufacture straps completely customized to your exact requirements. From unique color matching (Pantone) and custom branding/logos (laser etched on buckle or molded on strap) to modified vent patterns and proprietary hardware designs, our engineering team will bring your vision to life.
Technical Insights FAQ
Q1
What is your typical Minimum Order Quantity (MOQ) for this custom molded product?
For standard configurations (like the matte black shown), our MOQ is generally lower. However, for fully custom colors, branding, or modifications requiring new mold tooling, the MOQ typically ranges from 500 to 1,000 units per size/color, depending on the complexity. Please contact us with your specific customization details for an exact quote.
Q2
How do you ensure quality control for such intricate perforated designs?
Our quality management system covers the entire production cycle. Before mass production, we perform rigorous FAI (First Article Inspection). During injection molding, our technicians monitor critical parameters (temperature, pressure, cycle time) to ensure consistency. Post-molding, 100% manual visual inspection is performed to check for flash, short shots, or blocked vent holes. Finally, sampling plans (AQL standards) are used for final QC before shipment, including tensile strength tests and buckle salt spray resistance tests.
Q3
Can we request a specific shore hardness for the silicone material?
Absolutely. As a direct manufacturer, we can adjust the silicone formulation to achieve your desired Shore A hardness rating (typically between 50A and 70A for watch straps), balancing soft feel with necessary structural rigidity.
Q4
What is the lead time for new custom projects?
For complete OEM projects involving new molds: Tooling design and fabrication typically take 25–35 days, followed by 7–10 days for sample approval. Mass production generally takes 20–30 days after sample confirmation, depending on order volume. Repeat orders for existing molds are significantly faster.

Frequently Asked Questions
1
Is this silicone watch strap safe for people with sensitive skin?
Yes. The strap is manufactured from high-grade, hypoallergenic silicone rubber that is food-safe and free from harmful chemicals. It is specifically formulated to minimize the risk of skin irritation, making it suitable for prolonged daily wear even for individuals with sensitive skin.
2
Will this strap fit my smartwatch or traditional watch?
This strap is designed as a universal fit accessory, available in 18mm, 20mm, 22mm, and 24mm lug widths. It is compatible with the vast majority of smartwatches (such as Samsung Galaxy Watch, Garmin, Fossil, etc.) and traditional watches that use standard spring bar lug systems. Simply match your watch's lug width to the correct strap size.
3
Can I use this strap during swimming or water sports?
Yes. The silicone material is fully waterproof and resistant to sweat, chlorine, and saltwater. The perforated design also allows water to drain quickly, making it ideal for swimming, surfing, or other water-based activities. The stainless steel buckle is also corrosion-resistant for long-term use in wet environments.
4
What customization options are available for bulk or OEM orders?
We offer comprehensive OEM/ODM customization including: custom colors (full Pantone matching), custom logo engraving or molding on the strap body, laser-etched branding on the buckle, modified perforation patterns, custom strap lengths and widths, and proprietary hardware finishes. Our engineering team provides full DFM (Design for Manufacturability) support throughout the process.
5
How durable is the stainless steel buckle, and will it tarnish over time?
The buckle is made from 304L brushed stainless steel, which is highly resistant to corrosion, rust, and tarnishing. All buckles undergo salt spray resistance testing as part of our standard QC process to ensure long-term durability under daily wear conditions, including exposure to sweat and moisture.
6
Can I request a sample before placing a bulk order?
Absolutely. We strongly encourage sample evaluation before committing to a bulk order. For standard configurations, samples can typically be arranged quickly. For custom OEM projects involving new tooling, sample production follows the mold fabrication stage (approximately 25–35 days for tooling, then 7–10 days for sample approval). Please contact our team to initiate a sample request.
