AI-Powered supplier vetting

SummaryBeijing OKSUltrasonic Group Co., Ltd is identified as both a trading company and manufacturer/factory based in Beijing, China, supplying ultrasonic generators, transducers, piezoelectric ceramics, vibration systems, and related equipment. The supplier states that it holds ISO 9001 certification, operates six production lines, and has more than 15 years of experience in high-power industrial ultrasonics. Its stated capabilities include one-stop parts or complete equipment customization. Export activity is extensive by self-reported scope, with 90% of sales from exports and markets across multiple regions; quoted trade terms and several payment methods are supported. Production and delivery information indicates output of more than 10,000 standard generators and circuit boards annually and lead times within 15 workdays in both off-peak and peak seasons. Evidence of customer transactions is limited to two recorded transactions involving one Mexican buyer in 2025. Financial strength, detailed after-sales...

Supplier typeThe supplier is explicitly classified as both a trading company and manufacturer/factory. Its stated product scope covers ultrasonic generators, transducers, piezoelectric ceramics, vibration systems, and ultrasonic equipment, indicating participation in both manufacturing and commercial supply.

CertificationsThe supplier reports holding an ISO 9001 management-system certification. This is explicit evidence of a recognized quality-management certification, although the certificate scope, issuing body, and validity period are not provided.

Production capacityThe supplier reports six production lines, facilities covering 2,000 square meters with a 3,500-square-meter building area, annual output exceeding 10,000 standard ultrasonic generators and circuit boards, and lead times within 15 workdays in both peak and off-peak periods. These stated capacity and delivery indicators support a positive assessment, although independent verification is unavailable.

Customization capabilityThe supplier explicitly offers one-stop parts or complete equipment customization and lists ultrasonic generators, transducers, piezoelectric ceramics, vibration systems, and ultrasonic equipment among its products.

Product Q&A

Q:What frequency ranges are available for this machine?

The machine supports multiple frequencies including 15kHz, 20kHz, 28kHz, 30kHz, 35kHz, and 40kHz depending on the power model.

Q:How does the automatic frequency tracking work?

It uses digital frequency synthesis and phase-locked loop technology to automatically adjust to the best resonance point, eliminating temperature and load effects.

Q:What safety protections are included?

It features six intelligent protections: output overcurrent, overvoltage, input overcurrent, frequency sweep failure, overtemperature, and excessive power.

Q:Can the amplitude be adjusted during operation?

Yes, the amplitude can be adjusted steplessly from 0 to 150% instantly to prevent defects and ensure perfect welding.

Q:What is the lead time for delivery?

The lead time is within 15 working days for both peak and off-peak seasons.
