MANUFACTURING PROCESS OF HYUNDAI MOTORS
Stamping
In the Stamping Shop, the vehicle begins to take shape. Housed in the shop are large rolls of steel, each weighing between 20,000 and 40,000 pounds. Cranes are used to lift the rolls and put them into the blanking machine, where rectangular pieces, thin as a dime, are cut and stored in racks. The pieces are automatically moved to one of two large, stamping presses with dies molded into various shapes. Over 5,400 tons of pressure transforms the steel blank into a specific body part.
Welding
The Welding Shop containing 280 robots capable of maneuvering and welding body parts. These amazing automated machines position stamped body parts and accurately weld them together to form the vehicle body, called a “body-in-white.” Both the Sonata and Santa Fe vehicle bodies move down the same assembly line at HMMA. Team Members attach hinges, doors, hood and trunk, then check the quality of each car body to confirm the welding process is perfect.
Paint
The completed “body-in-white” moves from the Welding Shop, along a trestle into the Paint Shop for the nine-hour painting process. The vehicle first rotates 360 degrees in a unique electrocoat bath to prepare the entire body for paint. Eighty-one robots apply primer, a base coat using one of 15 different water-based paint colors, and a final clear coat which provides a beautiful shine and long-lasting protection. Since the Paint Shop is an environmentally-controlled area, Team Members must wear special overalls and gloves to protect themselves and the paint’s finish. A single particle of dust can affect the overall quality of a vehicles paint finish. The Paint Shop has over four miles of conveyor systems to move the vehicle bodies through each different process. After drying, the freshly-painted vehicle body heads to General Assembly.
