Battery Lead alloy Bushings types:
The lead acid battery's lead bushings are the crucial component for connecting the positive and negative plates. Crafted predominantly from pure lead and 3-5%antimony, it facilitates the flow of current within the battery. As per different manufacturing methods, lead acid battery Negative/Positive poles/bushings can be classified:

Gravity casting cold forming lead-acid battery bushings
Cold forming bushings or cold forged bushings manufacturing process uses gravity lead alloy parts casting machine and mold to produce gravity bushings parts. Then use a heavy stamping machine and mold to press rough gravity bushing to precision sized parts. Then use the NC turning and rolling machining method to cut flash and get a finished bright battery bushing.
Gravity-casting battery bushings can be used directly. The gravity-casting battery bushing and cold formed bushings photo shows:
The gravity-casting lead-acid battery bushing manufacturing process:
Our top-quality cold-forming lead bushing offers outstanding conductivity and robust corrosion resistance.
1. Lead parts gravity casting machine with molds to cast lead alloy bushings as per design. (after this process, we can get a gravity-cast bushing. Most battery factories use this bushing directly for plastic injection to produce lead acid battery container covers.)
This gravity bushing features no-airholes, most battery factories use this bushing with plastic injection to produce battery cover directly.

2. As improved bushings, we provide cold forming (cold forged) bushings as per customers' demand. The bushings are made by high pressure and lathing machining, the finished parts with high precision, high density, and no air holes. Undercut labyrinth structure (arrowhead rings) can be done.
Now, we provide 3typs cold forged battery bushings:
