Bowling Green, Kentucky, U.S.

The manufacturing plant in Bowling Green, KY, produces finished flat rolled aluminum sheet products for the growing automotive market in North America. Run by the joint venture Constellium-UACJ ABS LLC, the manufacturing plant houses a capacity of 100,000 metric tons.

The plant supplies 5 and 6xxx alloys, and 7xxx alloys for ultra high strength requirements, with a wide spectrum of thicknesses and width, and provides coils and sheets for closures inners, outers and body in white.

About Constellium-UACJ

Constellium and UACJ signed in May 2014 an agreement to supply automotive body sheet to the North American automotive industry under a joint venture, Constellium-UACJ ABS LLC.

Constellium-UACJ ABS LLC offers a leading product portfolio covering the entire range of flat rolled sheet products for closure panels and structural parts, with a significant industrial capacity to serve the North American automotive body sheet market. By joining strengths in technology, know-how and customer relationships of the two parents company, Constellium-UACJ has become a privileged global partner for North American OEMs.

The manufacturing plant in Bowling Green is run by the joint venture Constellium-UACJ ABS LLC, KY is ideally located near major OEMs plants and houses a capacity of 100,000 metric tons of finished coils and sheets which can be directly stamped by OEMs or  Tier1 stamping units.

The plant supplies 5 and 6xxx alloys, and 7xxx alloys for ultra high strength requirements, with a wide spectrum of thicknesses and width, and provides coils and sheets for closures inners, outers and body in white.

Technology

The plant uses top notch technology including:

  • High speed of thermal treatment
  • Precise control of temperature
  • Highly efficient quench
  • Chemical section with 2 spray zones for two types of conversion material

This high technology opens new possibilities for enhanced metallurgical properties

  • Higher strength products, higher formability, higher crash performance
  • And high surface quality in terms of roping & hemming properties
Heat Treatment and Quenching line

The heat treatment oven consists of 12 sections. The thermal cycle has temperatures in excess of 500° and is determined through thermal simulation for each product, and then confirmed in the qualification process.

The water quench unit enables to produce high strength and high ductility heat treatable alloys. The air quench unit brings the coils to room temperature.

Surface treatment line

The surface of the sheet is either acid cleaned or pretreated according to customer specifications.

The performance in paintability, weldabililty and corrosion resistance of the final automotive body sheets are determined through this line.

Completion line

The Completion Line is used for sample cutting, as well as, center cutting, rewinding and inspection of the aluminum coils once they have cooled to room temperature. Operators are trained to detect surface defects that can affect the final appearance of the vehicle painted surface.

Line Speed:  0 – 200 m/min 

Chemical and physical testing laboratory

Physical Testing: Tensile strength tests measure the force required to break a sample and the extent of elongation of the sample at the break point.

Chemical Testing: Chemical testing ensures delivery of a coil with the proper surface treatment. Key items measured are pH, conductivity, concentration. The chemical testing lab is also used to ensure that the plant is meeting our obligations to the environment.

Packaging line

The line is an automatic coil packing line. The coil is transferred by overhead crane to the coil deposit station where operator reads barcode and the coil gets product data from MES.

Sustainability

Bowling Green has been designed to optimize all waste and minimize our environmental footprint by tight control of air emissions and tight retention on our surface treatment workshop.
