| fissare per deformazione (o alternativa sotto) joining by bending Explanation: What is the definition of seaming? A bending operation that joins the interlocking edges of two separate metal sheets together by folding them over one another. What is the definition of bending? The shaping of sheet metal by straining the metal around a straight axis. A bending operation compresses the interior side of the bend and stretches the exterior side. Flanging, hemming, and seaming are all bending operations. You can also say "joining by tha plastic deformation of the supply valve" What is the definition of forming? The plastic deformation of a metal in order to produce a useful shape. Sheet metal can be formed through operations that shear, stretch, bend, or compress the metal.

fit by curling Explanation: in effetti l'orlo della la scatola di base viene "arricciato" par imprigionare la flangia della valvola. Il termine è visibile nelle fasi di produzione di scatole per cibo: Can end, punto 3 del sito. Reference: http://inventors.about.com/gi/dynamic/offsite.htm?zi=1/XJ&sd... |

compression forming/crimping Explanation: From: http://machinedesign.com/ContentItem/61632/Monitoringforceen... "The technique is similar to impact and compression forming where the tool applies a compressive axial load to plastically deform the material." from: http://en.wikipedia.org/wiki/Aerosol_spray "Packaging A typical paint valve system will have a "female" valve, the stem being part of the top actuator. The valve can be preassembled with the valve cup and installed on the can as one piece, prior to pressure-filling. The actuator is added after.Modern aerosol spray products have three major parts; the can, the valve and the actuator or button. The can is most commonly lacquered tinplate (steel with a layer of tin) and may be made of 2 or 3 pieces of metal crimped together. Aluminium cans are also common and are generally used for more expensive products. ***The valve is crimped to the rig of the can,*** the design of this component is important in determining the spray rate. The actuator is depressed by the user to open the valve; the shape and size of the nozzle in the actuator controls the spread of the aerosol spray |
