Market Trends of North America Automotive Parts Magnesium Die Casting Industry
This section covers the major market trends shaping the North America Automotive Parts Magnesium Die Casting Market according to our research experts:
Increased Application in Body Assemblies
Key body structure applications, such as floor rails, shock towers, and pillars, are now being manufactured using high-pressure non-ferrous castings. The use of magnesium in automotive body parts is limited, but it has recently been observed to be expanding.
GM has been employing a single-piece die-cast roof frame, since the introduction of C-5 Corvette in 1997. Cadillac XLR roadster's retractable hardtop convertible roof and top frame employ magnesium alloys. SUVs and Ford F-150 trucks are coated with magnesium castings, for the vehicles' radiator support, and Dodge Viper is coated with one-piece magnesium front-of-dash die casting. In Europe, for body panel applications, the German auto giants, Volkswagen and Mercedes, have employed thin-wall magnesium die castings. Thin-wall casing application constitutes a major part of magnesium usage in the automotive industry. Thin-wall die castings, such as closure inners, can often offset the material cost penalty of magnesium, over steel sheet metal construction, due to part consolidation.
The first magnesium die-cast closure to ever meet 55 mph rear crash requirements is used in liftgate inner panel, and the part is found in 2010 Lincoln MKT. The key aspect of manufacturing thin-wall castings, which are approximately less than 2mm, lies in the design of casting, using proper radii, and smooth die-filling of the ribs to stiffen the parts.
Environmental Regulations
The growing market for light weight vehicles to reduce CO emissions is identified as one of the primary drivers for growth in this market. Recent regulations, such as, the decision of Environmental Protection Agency (EPA) to raise mile per gallon standards to 35.5 miles per gallon by 2016, and then 54.5 mpg by 2025 have induced automotive manufacturers to shift their focus to the use of light-weight metals for producing automobile parts.
Rules imposed by Occupational Safety and Health Administration (OSHA) to develop the technical workforce in the die casting industry are expected to improve the overall production of the market. Moreover, initiatives by National Air Duct Cleaners Association (NADCA) to advance the technical workforce in the industry of die casting are also anticipated to foster the market growth.
