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: This is 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 FAQ
Q
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.
Q
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.
Q
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.
Q
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 (FAQ)
1
Is this silicone watch strap safe for sensitive skin or long-term wear?
Yes. The strap is manufactured from hypoallergenic, food-safe silicone rubber that is free from harmful chemicals. It has been formulated to be gentle on skin during extended wear, making it suitable for users with sensitive skin conditions. The ventilated design further reduces moisture buildup, which is a common cause of skin irritation.
2
What watch brands and models is this strap compatible with?
This strap features a universal lug design and is compatible with the vast majority of smartwatches and traditional watches that use standard lug widths of 18mm, 20mm, 22mm, or 24mm. This includes popular brands such as Apple Watch (with adapter), Samsung Galaxy Watch, Garmin, Fossil, Seiko, and many others. Please verify your watch's lug width before ordering.
3
Can I get custom colors, logos, or packaging for private label orders?
Absolutely. Full OEM and ODM customization is one of our core competencies. We support Pantone color matching for the silicone body, laser engraving or mold-in branding on the strap and buckle, and fully custom retail packaging. Please provide your requirements and our engineering team will prepare a tailored proposal.
4
Is the stainless steel buckle resistant to sweat and corrosion?
Yes. The buckle is made from 304L brushed stainless steel, which offers excellent resistance to sweat, moisture, and everyday corrosion. All buckles undergo salt spray resistance testing as part of our standard quality control process to ensure long-term durability in active-use environments.
5
What certifications or quality standards does your manufacturing process comply with?
Our manufacturing facility operates under strict quality management procedures aligned with ISO standards. Raw silicone materials are food-safe and comply with relevant international safety regulations. We conduct First Article Inspection (FAI), in-process quality monitoring, and final AQL-based sampling inspections before every shipment to ensure consistent product quality.
6
Can the strap length or hole pattern be modified to suit specific wrist sizes or ergonomic requirements?
Yes. As a direct manufacturer with in-house mold design capabilities, we can modify strap length, hole spacing, hole size, and hole pattern geometry to meet your specific ergonomic or aesthetic requirements. Custom tooling modifications are discussed during the DFM (Design for Manufacturability) review stage, and our engineers will advise on feasibility and associated tooling costs.
