Manufactur
01
Customer sends inquiry including trailer type, loading capacity, road condition, transport goods, and destination country requirements.
02
Sales and engineering team communicate with customer to confirm detailed specifications such as dimensions, axle brand, suspension type, tire size, steel thickness, and optional configurations.
03
Engineering department prepares 2D / 3D technical drawings. Customer reviews and confirms all technical details before production.
04
Final quotation is issued based on confirmed configuration. Both parties sign sales contract and customer arranges deposit payment.
05
High-strength steel plates, axles, suspension systems, landing gears, braking systems and other components are purchased from approved suppliers
06
Steel cutting, bending and beam forming. Main frame welding is completed by skilled welders or robotic welding systems.
07
Installation of axle system, suspension, braking pipeline, electrical wiring, landing gear and accessories.
08
Sand blasting for rust removal. Primer coating and final polyurethane painting to ensure corrosion resistance.
09
Full inspection including welding quality, dimensional accuracy, brake system testing, lighting system check and road simulation test.
10
Trailer is packed by wax spraying, tarpaulin covering or container loading (CKD/SKD if required). Shipment is arranged according to agreed Incoterms.
11
Technical support, spare parts supply and maintenance guidance are provided throughout trailer service life.
Manufactur
In semi-trailer production, the core functions of electrophoresis are corrosion prevention and priming:
Sandblasting is typically used to treat precision parts or special surfaces that shot blasting cannot reach：
In semi-trailer manufacturing, shot blasting is a core process before painting, using high-speed steel shot to impact the metal surface.
This is the key to Yuanda semi-trailers' "lasting new look": the powder coating is electrostatically sprayed and then melted at high temperature to form a film.
