TERM MEANING
PAILS High-capacity containers, characterized by having a lid with ato close the entire mouth of the container. It is fixed by means of a skirt divided into sectors that are folded over the flange of the mouth of the body. It is shaped like a bucket, hence its name. They are usually equipped with handles for handling. Its normal use is to contain paintings.
PALET

CLOSING PLATE

Closing mandrel

See locking mandrel.
COMPRESSION PLATE Closer part that receives, positions and holds the containerbody during the closing operation .. Moving in the direction of the axis of the containermoves the lid-body assembly lid-body assemblyhousing the lid in the chuck and providing a certain thrust (compression) during the cycle to maintain the body and the lid solidarity. Once this is finished, it descends, allowing the expulsion of the packaging. It is adjustable in position and force of compression. Its shape is a function of the packaging. The same as the chuckcan work by turning (for can empty) or fixed (full can).In the first case, the rotation can be produced either by the dragging of the mandrel (“crazy plate”) or by being linked to the seamer motor. seamer (“motorized chuck”)
POLYESTER

DUST
ELECTROSTATIC
Varnish in powder form to be applied on the inside of the electrically welded side seam of the body of a container to protect it from oxidation and chemical attack by the contents of the container.. It is applied by electrostatic deposition and subsequently requires the application of heat (baking) for its polymerization and adhesion on metal. It is generally white, although it can also be colorless or golden.

Presence of very small holes in the varnishedsurface of the sheet metal. It is measured by the number of pores per unit area. The higher it is, the better the quality of the varnishing is worse.
POROSITY
