Method for manufacturing a capsule made of aluminum for small tubes with seal and product obtained therefrom

Method for manufacturing a capsule made of aluminum for small tubes with seal, the method being adapted to make a capsule entirely made of aluminum, equipped with breakage pyramid adapted to perforate a security seal made of aluminum, present on the hole of the small tube;

• said method comprising the steps of:
• study of the physical properties of treated aluminum, by means of analysis of elasticity and heat and deformation resistance;
• analysis of the treated material by means of laser reading in order to ensure that the dimensions of the aluminum sheet are adapted for the progression molding process;
• extending an aluminum sheet, engaging the aluminum sheet within a die adapted to maintain the aluminum sheet in position during the molding steps;
• molding of the capsule equipped with breakage pyramid, by means of the use of a progression mold which, through a plurality of passages, is adapted to sculpt and model said aluminum sheet up to reaching the desired shape, obtaining a capsule comprising a breakage pyramid adapted to perforate the aluminum membrane that constitutes the security seal of the small tube;
• removal of the modeled capsules, from the remains of the aluminum sheet that was left intact during the progression molding;
• quality control, carried out randomly on several of the molded capsules;
• cleaning of the molded capsules, by means of air jet, supplied by a compressor, adapted to remove every impurity and residues of the molding;
• painting of the capsules by means of painting, in line with the type of product packaged within the small tube;
• drying of the capsules in dry and ventilated environment;
• storage of said capsules, awaiting use on the new small tubes.
