Home > Technology > Production Technology

We manufacture every battery component under fully controlled environment. We are not just an assembler that outsources plates & components for assembly. Our Automotive, Industrial and Traction batteries represent the major use of cutting edge lead-acid technology. We have two state-of-the-art factory plants located in Jiangxi, China & our sophisticated machineries are from USA, Germany and other reputed China companies having technological foreign collaboration.

世界杯预选赛竞猜Quality tests are not only carried out at every stage of production, but also at the final stage of assembly line every battery unit goes through HRD, Polarity, and Short Circuit test to ensure compliance with international battery standards in addition to JIS & DIN Standards. Evidently, our all batteries are free from manufacturing defects and guarantee 100% output, shelve & service life as mentioned in the specifications.

世界杯预选赛竞猜We use 99.99% pure lead and other high quality raw material procured from trusted sources so as to ensure reliable backward integrated supply chain to produce high quality batteries.


The major steps in manufacturing process, which is shown in the process flow chart, are described below in stages:

Step 1:

Oxide Manufacture:

We use milling process; solid lead (which may range in size from small balls to complete pigs) is fed into a rotating mill. The tumbling action of the lead generates heat and the surface of the lead oxidizes. As the particles roll around in the drum, the surface layers of oxide are removed to expose more clean lead for oxidation. The air stream carries the powder to a bag filter, where it is collected.


Step 2:

Grid production

世界杯预选赛竞猜Grid is made of 1# electrolytic lead with the purity of 99.994% as the raw material, and then combined with other raw materials casting into lead alloy. The high quality materials and technology has enabled us to produce grids with high density and high Sn content.


Step 3:

Pasting

世界杯预选赛竞猜Battery paste is made by mixing the oxide (made of #1 electrolytic lead) with water, Sulphuric acid and a range of proprietary additives. The paste is pressed by machine onto the grid network, and the plates are usually flash-dried in a high-temperature oven.


Step 4:

Curing

we create a low-temperature, high-humidity environment for the plates. Staying in curing oven under the serious controlled time to make the lead paste on the plate become harden, to give a good bond between the grid and paste. And the free lead in the plate is required to reduced to a minimum of 1.5%, far below the average e of 4%


Step 5:

Formation, Plate Cutting and Assembly

世界杯预选赛竞猜Cured & dried Battery plates undergo an electrical formation process In tank formation. Plates are loaded into large baths of dilute sulphuric acid and a direct current is passed to form the positive and negative plates. After drying, the plates are cut and assembled, with a HIGH-QUALITY SEPARATOR between them, into battery boxes. Plates of like polarity are connected by welding together the plate lugs.


Step 6:

Quality & Performance Tests

Before our batteries get packaged into cartons, they undergo following tests for performance, endurance and compliance with laid down standards. Any deficit in the performance results in the scrapping of the battery.
