There are two main types of watch ultrasonic Clean Factory: one is equipment factories that produce watch specific ultrasonic cleaning machines, and the other is precision cleaning factories that provide OEM ultrasonic cleaning services for watches/watch cases/straps. Below, we will explain from three aspects: core principles, mainstream factories, equipment selection, and key points of outsourcing.
Core principle (specifically for watch cleaning)
Ultrasonic cleaning relies on cavitation effect: high-frequency vibration of 40kHz – 1MHz generates microbubbles in the liquid, which burst to form instant high pressure (≥ 1000bar) and high temperature, peeling off oil stains, sweat stains, polishing powder, fingerprints in the gaps, carvings, and drill holes of the watch case/strap, without damaging the metal, coating, glass, and waterproof rubber ring.
Key points for equipment selection (by scenario)
- Household/after-sales maintenance (single/small quantity)
Frequency: 40kHz – 48kHz (universal, non damaging coating)
Capacity: 0.6-2L (with strap/case, not immersed in the movement)
Function: Heating (40-50 ℃)+Degassing+Timing (3-10 minutes)
Recommendation: Kangdesen and Gute ultrasonic desktop machines, factory price of 80-150 yuan. - Factory batch cleaning (case/strap, 100-1000 pieces/day)
Frequency: 28kHz (heavy oil pollution)/40kHz (universal)/80kHz (precision gap)
Configuration: Multiple slots (cleaning → rinsing → drying)+dedicated cleaning basket+anti vibration
Process: Water based neutral cleaning agent (pH 7-8) → Pure water rinsing → Hot air drying (60 ℃)
Recommendation: Smart and Jietai ultrasonic semi-automatic lines, with a unit price of 20000 to 100000 yuan. - High end wristwatch/movement components (micron level clean)
Frequency: 1MHz (megahertz, does not damage small parts)
Medium: Ultra pure water+anti-static additives
Environment: Clean room+vibration proof table
Recommendation: Jietai Ultrasound and Shengaoyuan customized models, with a unit price of 150000 to 500000 yuan.
OEM cleaning service (do not want to buy equipment)
Region: Bao’an, Shenzhen/Chang’an, Dongguan (Clock Industry Belt), Suzhou (Smart Watch)
Service: Case wax removal, strap oil/polishing powder removal, intelligent case oxidation+fingerprint removal
Price: 1-3 yuan per strap, 2-5 yuan per case (batch size ≥ 1000 pieces)
Delivery: 24-48 hours, supports doorstep pickup and delivery.
