Paint Can Lids
Clamping ring sets for paint cans consist of two parts:
- a clamping ring and
- an insert / plug.
For this purpose, Blema offers the worldwide unique solution of simultaneously producing both parts directly from the tinplate sheet on a single manufacturing line.
The following designs are available:
- single tight
- double tight
- triple tight
Manufacturing of Clamping Rings
An installation for the production of triple-tight clamping rings and inserts consists of the following machines:
portal press (KAPPA IV)
for the simultaneous manufacturing of inserts and preforms for rings from a tinplate sheet by means of a multi-die (punching)
The insert is already finished after this process step and leaves the press for packaging in a plastic or paper bag.
for finishing the preforms into clamping rings
- punching the inner disc
- forming of the ring contour (one or two steps, depending on requirements)
for automatic or semi-automatic packaging of the ends in plastic or paper bags
