Aerosol Cans

Aerosol Cans


Three-piece aerosol cans made of tinplate essentially consist of three components:

  • can body,
  • aerosol top (dome), and
  • aerosol bottom.

The can body is manufactured on an aerosol can line.

The manufacturing of aerosol domes and bottoms is carried out on separate aerosol end manufacturing lines.

These complex, fully automated installations consist of several individual machines, which are linked together by means of conveyor belts. Blema offers complete turnkey systems for all variants.

Through a unique Blema development three-piece aerosol cans in all formats can now be embossed, with the embossing exactly matching the decoration of the can.

Manufacturing of Three-piece Aerosol Cans

Can bodies for three-piece aerosol cans made of tinplate are manufactured on a fully automatic production line comprising the following individual machines:


for the cutting of printed and / or lacquered blanks from sheets of tinplate

Transfer system

for the automatic feeding of blanks to the welding machine

Welding machine

for bending the blank into a tube and subseqent welding of the tube

Seam protection system

for applying a protective coating (powder coating or wet lacquer) to the inside and outside of the weld in order to avoid corrosion

Curing system

for heat-treating the protective weld coating

Combination machine

for final processing of the can body and for seaming on an aerosol bottom and dome

The Blema-own, modular system GAMMA II for aerosol cans allows for the individual combination of the following process steps in a machine

  • Necking the can ends, i.e. reducing their diameter (one or both sides)
  • Flanging the can ends (both sides)
  • Seaming the can with an aerosol bottom (double seam)
  • Seaming the can with an aerosol dome (double seam)


for inline differential pressure testing of unilaterally seamed cans


for automatic collecting of cans on pallets (multi-ply with inlays and stretch wrap)
