Aerosol Domes and Bottoms

Aerosol Ends

Description

The production of closures for aerosol cans made of tinplate takes place - similar to the manufacturing of standard sanitary ends - on a fully automatic end manufacturing line in the following process steps for aerosol bottoms and domes respectively:

aerosol bottoms 

  1. punching the bottom from a sheet of tinplate
  2. pre-curling the outer edge of the bottom (for safe destacking and seaming)
  3. lining the bottom with compound (to tightly seal the double seam)
  4. drying of the applied compound

aerosol domes 

  1. punching the dome preform from a sheet of tinplate
  2. forming / punching / trimming the preform in multiple steps to finalize the aerosol dome
  3. lining the dome (to tightly seal the double seam)
  4. drying of the applied compound

A manufacturing line for aerosol ends (bottoms and domes) consists of several individual machines which are linked together by means of conveyor belts. Blema supplies a tailor-made complete turnkey system for the customer.

Manufacturing of Aerosol Bottoms

Aerosol bottoms of tinplate for aerosol can closures are manufactured on a fully automatic production line which comprises the following individual machines:  

portal press with sheet feeder

for punching the bottoms with a multi-die tool directly from the metal sheet

curler

for pre-curling the outer bottom geometry to facilitate later destacking and to pre-form the contour for an optimal double-seam closure (essential quality feature of aerosol cans) on a seaming machine

lining machine

for applying compound to the shoulder of the end for a tight seal on the can

drying oven

for drying the sealing compound (reduction of residual moisture)

packer

for automatic or semi-automatic packaging of the ends in plastic or paper bags

Manufacturing of Aerosol Domes

Aerosol domes of tinplate for aerosol can closures are manufactured on a fully automatic production line which comprises the following individual machines:  

portal press with sheet feeder

for punching the dome pre-forms with a multi-die tool directly from the metal sheet

conversion press

for the further processing of the pre-form to the finished aerosol dome in several steps (forming, punching, trimming) in a multi-step tool

lining machine

for applying compound to the shoulder of the end for a tight seal on the can

drying oven

for drying the sealing compound (reduction of residual moisture)

packer

for automatic or semi-automatic packaging of the ends in plastic or paper bags
