Machines for Making Cold Press Lead Bush

Advantages of cold pressing lead terminals

It belongs to the high-end lead parts products, the terminal is with anti-rotation design, the terminals are bright, with high compactness, can effectively prevent the terminal from acid climbing, completely eliminate the internal bubbles of the terminals. The finished terminals pass the baking testing, air hole corrosion testing, torsion testing, compactness testing, which are up to the qualified standards, the product quality is in the international leading level.

The  lead  terminal  adopts  the  way  of  cold  pressing,which  solves  the defects  of  the  terminal  such  as  crack,internal  air  hole,sand  hole,etc, greatly eliminates the  problem of acid crawling and terminal corrosion, and prolongs the service life of the battery.

 Process for Making the Cold Press Terminals

Terminal  made  by  gravity  caster→cold  pressing  →trimming→grooving

1.Automatic Gravity Casting Machine

Production  Capacity:3~4  molds/min  (one  furnace  one  machine);6~8 molds/min  (one furnace two  machines);

 2.High Precision Cold Pressing Machine

The cold pressing mold is the core for making the cold pressing product; Pressing machine is customized according to the technical requirement (stroke, pressure and speed is specially customized);Double press start button, with  light curtain  protection  (to  protect the  operator).Product ejection:the ejection device is used to eject the product,and then take it out manuallyEach mold has two cavities(production speed is about 6~10 molds/min)

 3.Trimming  Machine

It  is  used  for  trimming  the  remaining  material  of  the  bush  after  cold pressing.The mold has two cavities (production speed is about 14~18pcs/min)

 4.Grooving  Machine

It is used for making the groove, so that the PP material can combine the bush tightly,moreover,it will increase acid climbing distance and accordingly reduce acid climbing risk.
