Our Factory
Our 2,000 sqm facility is organized into four operational areas:
1. Wire harness production workshop — assembly of custom harnesses and cable assemblies.
2. Wire drawing and extrusion workshop — in-house wire and cable production.
3. Quality inspection area — incoming, in-process, and final inspection.
4. Warehousing and shipping area — storage, packing, and dispatch.
This structure keeps drawing, extrusion, assembly, inspection, and logistics under one roof, which supports consistent quality control and shorter lead times.
