Lead oxide is one of the major components in our batteries. It is prepared carefully by the high-performance ball mill manufactured by Lishan Taiwan Company, which is a well-known battery equipment manufacturer in the world. Our heavy-duty automatic mill is controlled by a micro- computer to guarantee precision and consistency. Parameters and collected data involved in the grinding process are set and recorded, respectively, to enable quality tracking. According to our QC reports, the oxide powder produced shows excellent homogeneity in terms of the oxidation level and the particle size. In addition, the unique technology of ultra-fine processing facilitates our batteries to perform especially well for high-rate discharge.
Different batteries need different lead-based alloy grids. To make the lead-based alloy grids which are critical parts in batteries, we are employing twelve casting machines that are made and designed by ourselves . To ensure the grids produced are qualified to be further processed, they will be examined by our QC personnel by means of the grid dimension, the thickness, the weight and the visual inspection. Note that checking performed at this stage is critical to high-performance plates which are essential to high-performance batteries.
Regarding the paste, we have our special formula, which is the proprietary know-how of our Company - this makes our batteries stand out in the market. The positive and the negatives paste compounds are prepared by two independent automatic mixing machines. There is a unique feature of the positive paste mixer: two kneading rollers were built in the mixer, the paste is kneaded while being mixed.
For the pasting process, it is performed by two sets of pasting machines: one machine is responsible for making positive paste; and the other one, the negative paste.
All positive and negative uncured plates are examined in terms of the plate’s thickness, the density and the moisture level.
Curing is the process by which strength and adhesion of paste to grid is established prior to formation and is retained by the material after formation. Since the curing process is time-consuming and we have to maintain a high production rate, Five sets of high-capacity fully-automatic curing chambers are employed. The relative humidity and the temperature are accurately controlled; the raw plates are deliberately arranged to actualize the optimal air circulation.
To support our current production output, seven assembly lines are used. Cast-on-strap (C.O.S) technology - for grouping and joining the plates of the same polarity in each cell - has been employed for all our batteries. Years of continual improvements and experience of this C.O.S technology result in making joints which are mechanically strong and well bonded; and they possess good corrosion resistance and offer low electrical resistance as well.
We have a high-capacity computer-controlled battery charging production line to make sure that our batteries are properly charged in an efficient manner.
