BIW (Body in White) engineering prototype design is a critical stage in early vehicle development, focusing on the structural layout, material distribution, joining strategy, and manufacturability of the vehicle body before physical tooling and production begin.

This BIW engineering prototype design provides a complete visual and structural reference for prototype vehicle development, allowing engineers to evaluate body structure integrity, component positioning, stamping feasibility, and assembly logic at an early stage. Such engineering prototypes help reduce development risks and optimize downstream tooling and production processes.

Dongguan Changdong Mold Co., Ltd. is an experienced manufacturing partner specializing in metal stamping dies, prototype tooling, and automotive prototype parts. Established in 2012, Changdong operates a 4,000-square-meter manufacturing facility and is certified to ISO9001 and IATF16949 quality management systems.

With strong in-house capabilities including CAE analysis, die design, CNC machining, wire cutting, welding, tryout, and stamping production, Changdong supports customers from engineering prototype validation to physical prototype parts and low-volume production. The factory is equipped with stamping presses up to 800 tons, enabling seamless transition from BIW design concepts to real stamped prototype components.

BIW engineering prototype designs like this are widely used in prototype vehicles, concept validation, structural optimization, and preparation for prototype stamping and assembly.
