Automotive batteries in order to adapt to new environmental requirements further lightweight, in-vehicle electronic equipment increased requirements further enhance product reliability, and therefore automotive batteries in urgent need of updating product of the times. To meet the needs of Japan's Furukawa company exclusive use of technology - Casting plates developed lightweight, a new series of high-power battery.
 
     Automotive batteries use of the environment due to engine power of the equipment and machinery as a result of the increase in the engine room to narrow temperature rise, and the result of the increase in electrical equipment, electrical load increases, led to the use of harsh conditions, and in this context to improve battery High-temperature durability requirements of the growing ever louder.
 
     From the various considerations, vehicles and fuel trucks load up for the upgrading of the lightweight and dramatically reduce the cost of the new requirements. Automotive batteries from the traditional low-antimony mixed to the change. In addition, the sedan series lead to the improvement of calcium, and by excellent performance of the specifications change. By being grid alloy, clapboard specification parameters, such as improving substantially improve the high-temperature durability for the plate production equipment manufacturing process and the assembly process control automation further enhance product reliability.
 
     In the battery manufacturing process, the basic grid approach to the traditional manufacturing-books (gravity casting), an intensive, continuous casting of three kinds, but lightweight and performance aspects to consider, and tended to increase. Casting and two kinds of ways. Based on the above reasons, Japan's Furukawa company using continuous casting production processing grid.
 
     Casting a book-grid
     The traditional way is to cast molten lead into the grid of casting from the mold.
Generally cast is a two grid for a long time solidification, production efficiency is low. In addition, the following 1 mm grid casting thin molding a certain degree of difficulty.
 
     2 dragnet grid
     From the 1970s on the world was introduced to increase grid, the grid in the calendar rolling incision into the lead, stretching about a widening net mesh grid that is the manufacturing process. Continuous manufacturing production due to good performance, the use of thin lead with a light grid can produce, but this approach must be used with lead in the processing of very ears, a punching shear processing needs a long time, and, grid Structural design is limited. Lead with a variety of modes of production, but the majority of lead use will be thick with thin calendar for the lead belt. Lead calendar grid with that of the surface is the shear surface incision. Casting grid and the difference is planar high precision, the adhesion properties of live material and the book casting grid than poor, therefore, strive to lead paste and smear method of filling in areas such as improving.
 
     3 continuous casting method
     Continuous casting method is used in the late 1980s, this approach is in the rotation rolling die with the fixed mold, continuous injection from casting of molten lead. Due to the continuous casting of grid performance, and stable quality, production can be thin grid. Mold is a special drum shape, the high cost of the mold.
 
     Casting plate production, from continuous casting processes and pasted, shear component sub-processes. Lead casting processes from melting furnaces, rotary rolling mold, the mold formed. By melting furnace for uninterrupted supply of lead-melting through the rotation rolling mesh Rolling Die Molding and solidification, the solidification of a row of the grid, by the carrier transmission devices. Molten lead when it was passed, and rolling in the mould and die for a short moment contact solidification, therefore, the injection pressure melt lead, and rolling the rotation speed of transmission intensity and the management of very strict. In addition, mold Stripping special liquid release agent has been replaced by the traditional book-style cork powder release agent.
 
     Tu Tu paste filling process by the machine, rotary cutter, preheat drying furnace, pasted plate, plate-stacking components. Tu Tu cream machine using steel strip replaces the traditional smear machine used by the board cloth coated strip, lead paste from the bottom of the hopper squeezed out, drawing in the net grid with the same, plus or minus adhesion pasted paper at the same time Tu paste. Casting grid thickness of 1 mm or less than soft, due to pressure pasted easily lead to deformation, therefore, through improved from the hopper bottom paste extrusion process, pasted detection device used after detection, continuous plate ears By controlling the rotation speed of the rotary cutter and provisions of the shear size plate, plate shear down in the preheating drying furnace automatically placed in the dry plate rack.
