An automobile manufacturers to find a new way to reduce weight, also can keep familiar with the texture of steel sheet.This method is in production use Litecor, namely into two pieces of sheet metal composite plastic filling.
Volkswagen Polo R WRC (world rally) using the hood thyssenkrupp Litecor production of the company.This process can make whole hood weight 30%, thereby reducing carbon dioxide emissions by 25%.The invention for the 16th central society of plastics engineers automotive innovation won the highest award.
Litecor adopts two layers of 0.2 ~ 3 mm steel plate with 0.3 ~ 1 mm "special thermoplastic blend fiber membrane core layer.Headquartered in Germany, eisen thyssenkrupp company not announced details of the structure of filling materials, but in 2012 the company obtained the patent description points out: the soft-core base material is PP, PE, nylon, or contain other hybrid materials.
During the ceremony, the original BMW company executives, the current 2 r Kunstofftechnik and Buro fur Kunststofftechnik consulting group chairman Rudolf Fernengel, 'said Mr BMW have been exploring plastic steel plate to make inner core body panel, but the plastic is too thick, without success, and the public is more economic method did it!
Thyssenkrupp in its factory prefabrication of Dortmund in Germany made the 2500 pieces of Litecor hood, the factory have a Litecor precast slab production line, can produce 30 meters long, 8 m wide, 6 meters high Litecor board.The annual output can reach 10000 tons.Thyssenkrupp in 2013 years to build this production line.
At the same time, the public in the factory of navarre, Spain using steel plate stamping production for this batch of the hood of the masses.
Litecor plate can be in the assembly workshop by standard spray paint production line.
Thyssenkrupp has identified at least 14 kinds of Litecor plank USES, are mostly used in large flat and high intensity body parts such as roof, doors, doors and hood.And comparison of all steel design, thyssenkrupp Litecor production is found that the hood will be 21% more expensive, door 7% more expensive, but the cost is much better than aluminum.
Thyssenkrupp also studied the feasibility of using Litecor the chair, said Litecor is an ideal material to interior structure, because it is more light than the whole piece of large steel plate, can replace aluminum, especially in the market is sensitive to the cost of production.
