Tool Room · In-House Mould Fabrication & Maintenance

Tool Room

Our in-house tool room gives us direct control over the moulds behind every component we make. From mould fabrication and modification to scheduled periodic maintenance and emergency repair, the tool room supports our 31-machine injection floor — reducing dependency on outside vendors, protecting quality and shortening lead times. Combined with our central monitoring room and quality lab, it lets us maintain consistent, defect-free output batch after batch.
