for PE, AGM, and leaf-type elements

Cast-on-Strap battery machine RoCOS X1 for unloading & boxing


The heart of every battery production is surely the cast-on-strap machine

With our RoCOS X1, you get the fastest cast-on-strap machine with a single mold in the world. Process up to 5 batteries/min with PE and 4 batteries/min with AGM elements. 

machine details

If you want to achieve high-quality straps, a chain of optimized processes must be followed

  • loading & aligning of elements
  • lug preparation
  • casting
  • unloading & boxing

Mainly driven by servo motors, our COS machines include many innovative features.

station 1

loading & aligning of elements

  • swivelling arm or by robot (RLS)
  • element aligning (vibration table, lateral, and on lugs)

station 2

lug preparation 

  • brushing (optional)
  • fluxing (continuous filling and level control)
  • preheating (controlled drying, permanent temperature control)
  • tinning (for VRLA batteries)

station 3


  • precise, stable, and lead-saving

station 4

unloading & boxing

  • overhead gantry or robot system
  • active boxing frame for PE
  • compression unit for AGM
