Aerosol Domes: Saving Material Up To 11%

Is it possible to further lower the costs for the production of aerosol domes? The answer is YES, through the innovative equipment of INVERNIZZI PRESSE that is designed to produce particular drawing parts in the specific case domes for spray cans, with material of reduced thickness and having different hardness from TH435 to TH550, with or without coating (EN 10202-04).

The use of these materials with higher hardness values, than the materials normally used for the production of similar pieces, it allows to obtain particular drawing parts using a tin plate with reduced thickness. In fact with this system the end-use has the possibility to produce the domes using a material hardness TH550 and a thickness of 0.32mm for aerosol dome 60mm diameter and 15 bar and a thickness of 0.33mm for aerosol dome 60mm diameter and 18 bar. The obvious advantage that is achieved by producing the special parts in this innovative manner is that we have an impact not only on the economic aspect, by using less raw material, but also the reduction of the emissions in the atmosphere. There are operations that take place in this transfer system, such as the CURLING where to eliminate the residues of the processing dispersed in the environment, the machine is equipped with an aspiration system for the purpose of evacuating the dust produced by the wrinkling of the coating of the material. This activity is also designed to simplify the collection and therefore the proper disposal of processing residues, avoiding the dispersion in the environment of machining dust through channels and magnetic conveyors which convey the processing scrapes in an appropriate collection point. The entire process has been subject of study to achieve the construction of a machine able to guarantee also in the future the same initial performance

 
DMT – AD INVERNIZZI PRESSE AEROSOL DOME MANUFACTURING LINES MAIN FEATURES

• High volume production of aerosol dome production with 1 or 2 pieces at stroke.
• The press and transfer tool sets are studied according to the last aerosol markets needing in term of material hardness. The project foresees material hardness TH435 and TH550, T5 tinplate for material saving
• Dynamically balanced high speed transfer press:
• Press accuracy (using pre-charged roller ram guides, bearing guided, tool columns, etc.) and frame rigidity guarantees the max reliability for the repeatability of the stamping conditions.
• Mechanical reduction gear to allow press to supply the nominal energy even at a low number of strokes/min. Special drive unit of new design consisting of 3 thrust planetary gears. The extremely low moment of inertia of the thrust unit ensures highly reduced breaking angle.
• Special hydraulic unlocking system for fast and safe release of the ram in case of tool stuck at BDC.
• High efficiency.
• Tool active parts carbide.
• Simple tool setting guarantees a continue and uniform stamping quality, nor tool adjustment required during the production
• Rapid production exchange system.
• Complete finished tops production ready for lining.
• Feeding device designed to prevent scratching of pre draw shell (cups) or scroll/strip.
