How does the can body maker work?

1 Blank feeding of can body making machine

The tinplate strip is put as stack on the automatic feeder of can body maker, then the strip will be sucked by suction cup piece by piece and sent to the next station.

2 Pre-curling of seaming lock bodymaker

When the tinplate is fed into the machine, the feeding roller will curl the edge of strip slightly, preparing for the future forming of tin box body.

3 Corner cutting of lock seaming bodymaker

The corner of the tinplate will be cut, preparing for the following station of tin can body.

4 Folding, forming and seam locking of can body making machine

For the three piece non welded can, tin box or metal container, the side seam is not welding, it is seam lock by the edge of the tinplate, so the tinplate should be bended firstly according to the required shape, then forming the hooks on the edge, and locking each other together as side seam. This process can by completed by one set of automatic and combination tool on the tin can seam locking machine.

5 Flanging of tin box machine

If the can diameter is less than 150mm, after the output of the automatic bodymaker of tin box, GR can produce a automatic horizontal flanging machine closed to the output tool of combination bodymaker, then flange the edge of can body simultaneously. And the tin box maker does not need to install an independent tin box flanger.



1 Automation and combination

For the conventional technology, the curling, corner cutting, bending, hook forming, shape forming, seam locking are completed by independent machine, this solution is low efficient and high production cost, for GR automatic tin box making machine, all the stations are combined as one machine, by changing over the tool for any shape of gift tins, biscuit tins, food tins, fancy tins etc. This is smart, automatic and combined solution for tin production.

2 Cost reduction

For the conventional technology, each station and each machine require one worker to operate the single machine, the speed is low, but the cost is high. And for our automatic tin box making line, each station is combined as little machines, the worker just need to put the tinplate on the machine and start it. Everything is automatic.

3 Flexible and multi-functional

For different shape of three piece non welding cans, the shape and size changed is just to changing over one set of tool on the machine, the soft design concept is very popular in the general line tins.



For the 3 piece tin box, the tin box making machine can be changed over tool for different types of tins.

*Shape: round tin box, square tin box, rectangular tin box, irregular tin box, triangle tin etc.

*Function: fancy cans, gift cans, biscuit cans, candle cans, food cans, toy cans etc.
