Cast-on-strap Machine

Custom Industrial Machines


COSMEC GROUP cast-on-strap machine connects battery plates in 4-stage circular machine with rotating table, which provides access to all stations. The machine handling all type of batteries, well supported on a hydraulically powered frame, equipped with:

  • loading station
  • fluxing station
  • casting station
  • main lead pot, gas heated
  • unloading/boxing station
  • control panel
  • Vibrating table

Loading station

Groups of cell are loaded, lugs up, onto the loading station. Plates and lugs are aligned via a vibrating table and clamped in the right position.

The loading jig are universal types so that only two sets of loading jigs, are


Fluxing station

The second stage ensures the correct welding of the lugs through consecutive brushing and fluxing operations. First, all lugs pass through surface alteration and then passing to the fluxing unit to guarantee better attachment of the lead during casting.

Casting station

Mould and secondary lead pot are parts of the station. The secondary

lead pots are electrically heated. The lead is fed from the secondary lead pots to the mould by special discharge cocks controlled by the control panel. Water circulation inside the mould chills the straps and posts.

When the casting operation is finished the groups are transferred to the unloading station for the boxing

Unloading station

The casted groups are clamped and fed to the boxes.

Main pot

The lead, melted by a gas or electrical system, is fed to the secondary lead pots by

special pumps equipped with control valves.

Control panel

A dust-tight control panel with Mitsubishi microprocessor, fuses, isolators and plug-in relays for easy maintenance is provided

Ventilation and safety

The machine is equipped with a hood for aspiration of air and it must

be connected to the factory’s aspiration system.

The machine is safe for people in charge of its functioning and is conform to the European Safety Regulations standards. The machine is delivered with conformity declaration (CE)

The machine is designed to process all types of batteries.
