    At present, in terms of power transmission systems, the electrification technology of hybrid vehicles and electric vehicles has attracted much attention; in terms of safety technology, automatic braking and autonomous driving have attracted much attention

    .
    In the future, cars may also require innovation in production

    .
    In this sense, Daihatsu's attempt to promote production reform through the extensive use of resin bodies can be called the prelude to a major transformation of the plastic coating production line, and its trend is worthy of attention

    .


    Generally speaking, the car body must go through three coating processes: electrodeposition coating, intermediate coating, and surface coating

    .
    Therefore, the coating production line is very long.
    For Daihatsu's Copen, the electrodeposition coating line alone is 200m long

    .
    However, if the outer panel is not painted, the painting process can be greatly shortened

    .


    For example, in Copen, the body painting other than the door only needs to be electrodeposited

    .
    For electrodeposition coating, instead of using a conveyor belt to slowly move the vehicles, a batch process of immersing vehicles one by one for about 20 minutes can be used instead of using a conveyor belt, thereby shortening the production line

    .


    In the previous electrodeposition coating, considering that the coating should be painted, most of them were gray, while Copen's electrodeposition coating was changed to black

    .
    The area not covered by the outer panel will expose the electrodeposition coating surface.
    After the uniform is black, the trouble of secondary coating according to the color of the outer panel can be saved

    .


    Furthermore, if even the car doors can be made of resin, then the painting production line on the car assembly line can be omitted

    .
    As for the outer panel, it can be completed only by installing the panel painted in other processes with screws, etc.
    , just like assembling a plastic model, just by assembling the production line

    .


    Dafa’s move also implies a challenge to this new production method

    .
    Overseas, BMW "i3" uses aluminum alloy frame and carbon fiber reinforced resin matrix composite (CFRP) body to promote body resinization

    .
    The resin body is assembled by bonding, eliminating the need for welding

    .
    In addition, the British company Gordon Murray Design also proposed the "istream" production method, which combines the resin outer plate on the steel pipe frame, which can save the coating production line

    .


    In the automotive industry where new technologies for plastic coating production lines are emerging in endlessly, Daihatsu "Copen" relies on resin outer panels to enable offline operations for the coating process of engine hoods and fenders

    .
    Only the door is made of steel plate in order to meet the side impact standard, and the other outer panels of the body are painted offline
