Chassis & Frame Robotic Welding01

Chassis & Frame Robotic Welding

Precision automated cutting and rigid fixture clamping ensure structural integrity and tight dimensional tolerances under heavy load.

  • High-strength structural carbon steel tubing
  • Robotic seamless welding on key stress joints
  • 100% weld-penetration and alignment inspection
Cathodic Electrophoretic Primer02

Cathodic Electrophoretic Primer

Automated immersion tanks coat every exterior surface and interior tubular cavity to protect against rust in humid and coastal climates.

  • Automotive-grade eco-friendly cathodic primer
  • 360° internal cavity full coverage without blind spots
  • High salt-spray and moisture corrosion resistance
Electrostatic Spraying & Oven Baking03

Electrostatic Spraying & Oven Baking

Multi-layer electrostatic enamel coating baked at controlled temperatures produces a weather-resistant, durable, high-gloss finish.

  • Dust-free sealed spray booths
  • Dual-layer primer and protective clearcoat finish
  • Rigorous color-fastness and gloss level inspection
Assembly Line & Dynamic Road Testing04

Assembly Line & Dynamic Road Testing

Systematic torque-controlled assembly followed by full electrical, brake-force, suspension, and dynamic test-track validation.

  • Calibrated torque assembly standards
  • Full electrical circuit & high-load insulation test
  • Dynamic brake distance and steering test-run

Manufacturing Advantages

Our own manufacturing plant in Xuzhou, Jiangsu powers precision fabrication, rigorous quality assurance, and seamless container export coordination.

Rigorous Quality Assurance

Multi-stage inspections spanning raw steel testing, welding seam integrity, electrophoresis thickness, and final electrical load checks.

Modern Manufacturing Equipment

CNC laser pipe cutting, dedicated frame welding fixtures, automated cathodic electrophoresis, and bake-paint lines.

Flexible Batch Capacity

Efficient production scheduling supporting standard full-container batches as well as customized CKD / SKD knocked-down orders.

QC & Export Evidence

Inspection and shipment checkpoints that help importers control risk before payment balance and delivery.

01

Incoming Material Check

Chassis steel, traction motors, batteries, smart controllers, tires, and wiring harnesses undergo strict batch testing prior to assembly.

02

Welding & Paint Inspection

Critical weld seams, cathodic paint film micron thickness, adhesion rating, and anti-rust coverage are certified at each process stage.

03

Electrical System Test

Drive motors, smart controllers, battery discharge stability, headlights, signals, and electronic brakes are tested under simulated operational loads.

04

Pre-shipment Inspection

Every finished vehicle is verified against the purchase order for technical specifications, color codes, optional accessories, and spare kits.

05

Packing & Loading Photos

High-resolution photos and video recordings of interior pallet packing and container loading are provided for remote buyer sign-off.

06

Export Documents

Commercial invoice, detailed packing list, bill of lading, and certificate of origin (CO / Form E) are coordinated for prompt customs clearance.

Precision manufacturing in our factory guarantees reliable performance in your market.
