Metal soft tube and metal foil container making machine

A metal tube packaging container processing machinery
Hose is a special packaging container , primarily for packaging paste . Packaging containers commonly used hose metal hose , plastic hose and composite hose . Metal hose mainly tin, lead, aluminum and other soft metals as the material , and is currently the toxicity of tin and lead , are no longer used, and extensive use of aluminum as a raw material .

Aluminum tube features: aluminum tube sealing, and can protect the contents against the erosion of air and other contaminants , allowing the contents to a longer period without deterioration. Meanwhile pipe wall coatings can greatly improve the acid or alkali corrosion.
With aluminum tube for example, the process is: billet supply ( feeder ) → extrusion molding ( extrusion ) → Vehicle port threads ( lathes ) → annealing treatment ( annealing ) → surface finishing ( coating machine ) → drying ( dryer ) → printing ( printing press ) → finished product.
Aluminum tube production methods approximate two cans. First aluminum billet into the feeder or automatic feeding hopper , the feeding device into a felled by punch presses extruding a tube shape. Then by the special lathe -cut mouth cap screw , while the car out of the nozzle , tube tube shoulder length cut and press OK . Turning the mandrel to be inserted in the tube for easy gripping . In the extrusion process of aluminum hose material will harden , making it soft and easy to use , but also to be annealed. Wall coating epoxy paint , and then by drying, the outer wall of the printing , and finally they will have to be stamped with a hose filling a container . Hose tail is wide open, when you load the contents after flattening volumes two fold , forming seal intact , can be finished.
Second, the foil packaging container forming machine
1 . Overview of metal foil
Metal foil -like material there are many, is now widely used aluminum foil for packaging materials . Other common foil -like material with lead foil , foil , silver foil and so on.Because toxic lead and tin , and silver price is too expensive , so almost eliminated. As good foil impermeable , non-absorbent , non- oil , non-polluting packaging, ductile, light, elegant luster and other characteristics of the current in the packaging has been widely used , is now generally speaking multi-fingered metal foil packaging foil packaging .
There are two forms of aluminum foil containers . One is based on aluminum as the main body obtained by molding a molding container , also known as rigid or semi- rigid container , a cartridge or a disc type . The other is the bag container , also known as flexible container , mostly paper / aluminum foil, plastic / aluminum foil and paper / foil / plastic layer then the composite material. Polyesters such as cooking bags outer , the middle foil , inner layer of high density polyethylene, polypropylene or copolymers of polyethylene and polypropylene .
Its soft aluminum foil container processing machinery and plastic molding processing the same . Please refer to the relevant contents of the book .
Semi-rigid aluminum foil container aluminum foil container refers to folds , light wall rigid aluminum foil container aluminum foil container means . They are based on the 0.05 ~ 0.1mm thick aluminum foil stamping by the incomplete drawing ( folds ) and full stamping drawing is made.

2 . Aluminum foil packaging container processing equipment
This introduces a rigid or semi-rigid aluminum foil container processing equipment. These devices with two cans processing equipment similar to that used with composite die presses , while accompanied by the appropriate feeding and discharging mechanism and devices. Some need to accompanied by a separate die-cutting machine . Relevant organizations and devices , presses, die-cutting machine , etc. can reference book about plastic container forming machines or paper container forming machinery description.
Aluminum foil container molding equipment work process , as shown in Figure 17-32 . It can be completed simultaneously foil blanking , drawing , curling and other technology.Pull furrow die from 1,2 composed and installed on the press punch ( slider ) , and mounted in the lower punch 3 . The outer edge while landing a punch material effect ( as shown in the left half ) . Automatic feeding mechanism ( not shown ) on top of the aluminum foil placed 3,4,5 , when the upper die down, the foil by a blanking die with a blanking punch after punch to continue to drive 1,2 pulled into the next campaign will foil die 2, then change direction by aluminum foil outer tangential tensile stress in the wall and edge of the foil to form fan- folded edge nature , close to both the 2 and 3 when stacked side wrinkles stereotypes into a wrinkled shape. With the continuing upward punch , drive a , then press out the container straight edge . Time has come to the bottom dead center punch point ( as shown in the right half of Figure ) , the top block 5 to the first two workpieces suppress yield , followed by starting the punch return , a top foil is formed upward curling. If 1,2 are up and temporarily top out, leaving the container upright edges.Then you can get folds foil containers.
If in the process of punching aluminum foil completely deep drawing, the edge is not wrinkles, resulting foil packaging container wall will be as light containers. Light -walled container of plastic materials used in aluminum foil should be excellent , aluminum to reach 98 ~ 99%. With the precision mold manufacturing and also demanding.Compressed air can be used to replace the punch . General light wall foil container mold manufacturing costs than the folds container 3 to 5 times higher .

Coating equipment can be used in the inner and outer surfaces coated with aluminum foil containers resistant paint or coating thermal method in the cover part sealant .
