Automotive front-end module technology


The front-end module of a car is usually a multi-part assembly that brings together a large number of components. Automotive front-end module technology refers to the car front radiator crossbeam, radiator, headlight bracket and other parts of the modular design of the technology. Front-end modules cover lighting systems, engine cooling systems, vibration damping devices, air conditioning condensers and air cleaners, and engine compartment cover locks, hoses, fittings and partial harnesses.

Applications

Volkswagen, Ford and other foreign brands of automotive front-end module plastic successfully applied for many years. In recent years, independent brand car prices gradually began to carry out independent design and application of new materials research.

For example, SAIC-led FCV-863 project, the implementation of plastic front module, weight loss of 3.03kg.

Changan Automobile, exhibiting at the 2011 Motor Show, the compact CX30 compact sedan with all-plastic front-end module, consisting of 22 metal parts into an injection-molded part, greatly simplifies the front-end structure of the CX30 and reduces the weight of the part Up to 40%, and reduce the total weight of the car about 4kg.

Changan Yi 2015 2015 plastic front-end module of the original steel 10.13kg, plastic parts 6kg, expected weight loss 4.13kg, weight loss rate of 41%; and will be extended to C201, C206, C2X and other production models.

Great Wall Motor's newest model, which is mass-produced in June 2014, uses plastic front-end modules to reduce weight by 30% to 4.7kg. JAC is also mass production cars to promote plastic front-end modules and other products. In 2011, Chery Automobile undertook the project of "National Science and Technology Support Program for Development of Fiber-Reinforced Plastic Front-end Modules and Integrated Application on Target Vehicles", and successfully developed the plastic front-end modules and applied them to mass-produced models such as iResearch 7 )on.

In plasticizing front-end modules, SABIC partnered with SCANIA to successfully develop a front-end truck frame and deliver a modular delivery of parts from 5.15kg to 3.29kg with 33% weight reduction.

Why the front-end module loves LFT-PP eight reasons:

1) Function integration, a part of a variety of integrated functions;


2) small number of molds, reduce the cost of mold, reduce processing molding time;


3) reduce the installation process, saving labor costs;


4) reduce the types of materials for easy material recovery;


5) The structure is compact, easy to assemble, easy to install, disassemble and maintain;


6) simplify the body structure design;


7) Compared with metal parts is more corrosion-resistant, noise and noise reduction effect is good, more design freedom;


8) Can achieve more than 40% weight loss.
