The company operates from an 800 m² facility in Dongguan, Guangdong, with an annual output capacity of 200,000 units and serves markets in North America, Europe, and Southeast Asia.
Product Innovation & Technological Edge:
BAYI’s product range is characterized by a high degree of specialization and customization. Its portfolio includes standard models (100A, 300A, 500A, 800A) and non-standard models ranging from 1000A to 2500A, designed for specific customer requirements regarding product size, shape, and yield.
· Specialized Equipment Designs:
The company develops targeted solutions such as tape-type plasma polishing equipment for continuous roll processing, long-tube plasma polishing equipment for pipes over 2 meters, and chain-type plasma polishing equipment for automated batch processing.
· Core Product Specifications:
Models like the BY-100A Metal Plasma Polishing Machine feature a 30KW power input, a maximum output current of 100A, and a work chamber constructed from 316L stainless steel. The BY-800A Titanium Plasma Polishing Machine and BY-500A Jewelry Plasma Polishing Machine are engineered for specific material groups, offering a deburring rate of ≥ 99.9%.
· Process Advantage:
A key technological differentiator is the ability to polish at any 360-degree angle without requiring the workpiece hanger to be rotated externally during operation, simplifying automation and reducing cycle times.
Certifications & Compliance:
The company holds CE certification (Certificate No. 3N240806.DBAQC99) issued by Ente Certificazione Macchine, verifying compliance with EU directives for machinery (2006/42/EC), low voltage (2014/35/EU), and electromagnetic compatibility (2014/30/EU). The certification confirms adherence to standards including EN ISO 12100:2010 and EN 60204-1:2018.
Proven Performance & Case Study:
A project for client Hebei Hengxin in China involved the installation of 2 plasma polishing units for processing electronic accessories. Key highlights of this case include the guidance provided on installation. Customer feedback indicates the project has achieved stable operation over a 7-year period.
Production & Service Capability:
Operating on an OBM (Original Brand Manufacturer) model, BAYI offers customization such as deburring and polishing integrated machines. The company maintains a monthly production capacity of 70,000 to 110,000 medium-sized parts, with a lead time of 30–45 days and a minimum order quantity of 1 unit. Quality control involves 100% testing, and after-sales support includes remote technical assistance.
