Howon Co., Ltd

: 01. PNL ASSY-F/APRON & MBR COMPLETE
· A crucial longitudinal structural member at the front of the vehicle body. It absorbs impact during frontal collisions and manages input loads from front road vibrations during driving.
· Lightweight through the application of aluminum die-casting and extrusion. Mechanical fastening methods such as SPR (Self-Piercing Rivet), FDS (Flow Drill Screw), and REW (Resistance Element Welding) are utilized for assembling aluminum and steel parts.

: 02. CTR FLR
· Constitutes the lower center of the vehicle, serving as a core structural member that connects the front and rear body frames to distribute and transfer loads. It also ensures passenger cabin floor rigidity and enhances collision safety.
· Forming technologies like hot stamping and roll forming are applied for weight reduction and rigidity. Various joining methods, including SPOT welding, SPR, and laser welding, are used to assemble multiple panels.

: 03. PNL & MBR ASSY-RR FLR COMPLETE
· A major structural member at the rear of the vehicle, protecting the passenger space during rear and rear-side collisions. It houses the rear seats, fuel tank, and EV battery.
· To secure rigidity and reduce weight, lightweight materials and advanced forming methods are applied, including hot stamping, roll forming, and aluminum extrusion & die-casting.

: 04. PNL ASSY-DASH COMPLETE
· Separates the engine room from the passenger cabin and supports the front body load. It requires functions such as soundproofing, vibration damping, water-tightness, and thermal insulation from the cabin. Equipped with a Cowl Cross Bar for interior assembly.
· Employs hot stamping forming technology to improve structural frame performance.

: 05. PNL & HINGE ASSY-HOOD
· Determines the front design of the vehicle, protects the engine room, and acts as a shock-absorbing structure to reduce pedestrian injuries.
· Uses aluminum sheet metal for weight reduction and SPR for joining. · Met design scalability requirements for luxury vehicle models by applying a clamshell structure (extending the design to the sides of the fenders), a first in the domestic market.

: 06. PNL ASSY -P/ROOF
· Functions as a roof system that maximizes openness and natural light by configuring the front and rear of the vehicle roof with wide glass panels.
· Constructed with aluminum or steel, utilizing bonding, mechanical fastening, and sealing for assembly.

: 07. Front Door & Rear Door
· Located on the sides of the vehicle, separating the interior from the exterior for passenger boarding and alighting, and protecting passengers from external side impacts.
· Applies aluminum sheet metal and extruded aluminum for weight reduction, utilizing laser welding, SPR, and aluminum SPOT welding for joining.

: 08. Front Door & Rear Door
· Located on the sides of the vehicle, separating the interior from the exterior for passenger boarding and alighting, and protecting passengers from external side impacts.
· Applies aluminum sheet metal and extruded aluminum for weight reduction, utilizing laser welding, SPR, and aluminum SPOT welding for joining.

: 09. Fender & Member
· A crucial longitudinal structural member at the front of the vehicle body. It absorbs impact during frontal collisions and manages input loads from front road vibrations during driving.
· Lightweight through the application of aluminum die-casting and extrusion. Mechanical fastening methods such as SPR, FDS, and REW are utilized for assembling aluminum and steel parts.

: 10. TAIL GATE
· Determines the rear design of the vehicle and serves as a cover for the cargo protection space.
· Applies aluminum sheet metal and extruded aluminum for weight reduction, utilizing SPR, aluminum SPOT welding, and brazing for joining.

: 11. PANEL ASSY-TRUNK LID
· Determines the rear design of the vehicle and serves as a cover for the cargo protection space.
· Applies aluminum sheet metal and extruded aluminum for weight reduction, utilizing SPR, aluminum SPOT welding, and brazing for joining.

: 12. BIW (Body In White)
· Refers to the vehicle's body shell in the automotive manufacturing process, where all panels and structural components have been welded and joined together before painting or trim assembly.
· This framework is a core stage that determines the vehicle's fundamental rigidity and safety structure.
