Sinar Baja Electric commitment to the customers goes beyond simply assembly and sales support. We have spent many years creating a vertical supply chain for the most critical materials. Moving these processes in house improves quality, costs, on-time delivery and assures the finest product quality.

Quality Assurance Support

We ensure that the quality of our products are based on International Quality Standards as well as customer spesific requirements. There are 3 stages of Quality Assurance activities :

  1. Incoming Material Inspection; We check all parts appearance, dimensions, and additional parameters based on drawing and specification. 
  2. In Process Inspection; Our QA team control all production process stages, general characteristics, as well as special characteristics that are specified by customers.
  3. Final Inspection; All drivers are checked based on technical spesification and additional testing requested by customers.

To be in accordance with TS 16949 Quality System Standard, our Quality Assurance division has facilities such as:

  • Internal Calibration
  • Laboratory to do Environmental Testing and Power Testing
  • QC Production Set up for drivers, using Neutrik (NTI Analyzer) and Sound Check (Listen Inc.)






As part of vertical supply chain process, our in-house workshop utilizes mostly CNC machining. Precision from CNC milling, late, wire cute, EDM, and other conventional support equipment aids to the quality we promised to our customers. This also supports the making of our own tooling, jigs, fixtures, production tools, steel chassis tooling, and many other production machinery, making us the one-stop-for-all driver manufacturing company.
