The silicone strap of smart electronic watches has become the mainstream choice due to its comfort, durability, and versatility. The following is a detailed analysis of its production process, functions, and advantages:

1、 The production process of silicone watch straps

raw material preparation

Liquid Silicone (LSR): Food grade or Medical grade silicone with non toxic and anti additive properties, adjusted for color by adding colorants.

Mold design: Produce high-precision metal molds based on the shape of the watch strap (texture, hole position, buckle structure).

forming process

Injection molding: Liquid silicone is injected into the mold and cured at high temperature (120-180 ° C) to form the main body of the watch strap.

Secondary vulcanization: removes residual volatiles and enhances stability.

Surface treatment: laser engraving logo, spraying anti fouling coating, or embossing texture (such as imitation leather texture).

Post processing

Trimming burrs: Remove excess silicone by hand or machine.

Assembly accessories: embedded metal buckle pins, magnetic suction modules, or quick release structures.

Quality inspection: testing tensile strength, wear resistance, color fastness, and biocompatibility.

2、 The core function of silicone watch straps

Fixed equipment: Ensure the watch is securely worn and suitable for sports, daily use, and other scenarios.

Comfortable medium: reduces skin irritation through flexibility and breathability, especially suitable for long-term wear.

Function extension: Some watch straps integrate heart rate monitoring electrodes or magnetic charging interfaces (such as sports rings).

3、 The outstanding advantages of silicone watch straps

biocompatibility

Certified, low allergenic, suitable for sensitive skin.

environmental adaptability

Wide temperature resistance range (-40 ° C to 200 ° C), UV aging resistance, and no deformation for outdoor use.

Engineering performance

High tear resistance (such as a tensile strength of over 500%), with a lifespan 3-5 times that of ordinary TPU.

User friendly design

The quick release structure supports 3-second replacement, and the porous design is adaptable to different wrist circumferences (such as 16-22cm adjustable).

Silicone watch straps continue to consolidate their position in wearable devices through material science and process improvement.
