As India’s smartwatch and wearable device industry continues to grow rapidly, manufacturers face increasing challenges in maintaining precision and consistency in adhesive applications for miniature components. One critical process — thread hole dispensing — requires extreme accuracy to ensure proper screw fixation and long-term product stability.

A major Indian smartwatch manufacturer recently introduced the KSV1000A-U Auger Valve to solve recurring issues of inconsistent glue weight and poor uniformity in micro-hole applications. The target was to achieve precise adhesive control within a range of 0.2–0.3 mg per cycle, using a moisture-curing glue on threaded holes.

Consistent Performance for Micro-Scale Dispensing

The KSV1000A-U is an advanced precision auger valve dispenser designed for high-viscosity and particle-filled materials, such as thermal grease, UV adhesives, and structural glues. Built with a durable tungsten steel screw and closed-loop servo control, it ensures stable and repeatable dispensing — even for glue points as small as a millimeter.

Compatible with 10cc, 30cc, and 50cc syringes, the valve offers quick replacement and easy cleaning through its quick-release design, allowing operators to switch between materials without production delays. The augmented auger part options (8P / 16P / 32P) give flexibility to adapt to different fluid viscosities and application requirements, making it suitable for diverse wearable assembly processes.

 
Indian Customer Feedback and Results

After integrating the KSV1000A-U Auger Valve into their smartwatch assembly line, the Indian manufacturer reported several measurable improvements:

• Consistent glue weight control within ±0.02 mg per point
• Improved bonding strength for threaded holes, ensuring stable screw fixation
• Reduced rework rate caused by overflow or missing glue
• Enhanced production efficiency, achieving stable operation even with moisture-curing adhesive

By using the KSV1000A-U’s precise screw-driven control, the factory successfully automated a process that was previously performed manually, eliminating human error and ensuring every smartwatch unit met strict quality standards.

 
Strengthening India’s Wearable Technology Manufacturing

This success demonstrates how micro-dispensing automation is becoming essential in India’s electronics and wearable manufacturing sector. As product designs get thinner and more compact, traditional manual dispensing can no longer guarantee the accuracy required for components like smartwatch housings, camera modules, and micro-sensors.

The KSV1000A-U Auger Valve offers an efficient, reliable, and scalable solution that enables manufacturers to achieve repeatable micro-dispensing performance while improving throughput and maintaining high precision — key factors driving India’s growing wearable technology ecosystem.
