Short answers for production-line planning
What production lines does DUOYUAN build?
DUOYUAN builds bus and coach production lines, passenger vehicle production equipment, commercial vehicle production equipment, body-in-white welding lines, conveyor systems, final assembly and testing lines, and custom non-standard automation.
How should you start an RFQ?
Start an RFQ by sending vehicle type, target capacity, model mix, workshop layout, country, local installation capacity, and target SOP timing. The engineering team can then map BIW, conveyor, assembly, testing, CKD/SKD, and launch-support scope.
What should you prepare for CKD/SKD planning?
CKD and SKD projects need more than kit definitions. You should confirm process scope, local content goals, tooling boundary, training needs, trial-production plan, commissioning support, and acceptance evidence before comparing suppliers.
