Basic requirements: master metal two cans of structural features , the use of materials and processes
Teaching content: 1, two cans structure ; 2 , two metal cans manufacturing process ; 3 , the design of metal cans
Important and difficult: two cans of metal manufacturing processes
Hours Distribution : 6 hours

4.1 two cans structure
One , two cans composition
Two jars of body composition by the sidewalls and bottom of the tank . The molding method and multi -level light stretching stretching method .


2 , two cans Features and Specification
( A ) two cans of classification
① drawing tank
② thinning drawing tank
( 2 ) the characteristics of two cans
① outer surface can be fully printed and décor , improve packaging effect
② two cans lightweight , thin wall
③ cans with the bottom of the tank as a whole and seamless, high mechanical strength , good sealing
④ easy with lid seaming operation
⑤ molding process is simple, fast molding
( 3 ) two cans of material
( 4 ) two tank sizes

3 , two cans of structure

Cans
Lid
4.2 two jars of the body of the manufacturing process and quality testing

( 1 ) cans manufacturing process

① shallow stretch tank ( light red cans ) . Its draft cans and cans diameter ratio of less than 1
② stretching deep tank ( deep-drawing irrigation ) . Its tank height and tank diameter ratio greater than


③ thinning stretch tank

( 2 ) Quality Inspection



① the technical requirements for tank
② Quality Inspection Method

4.3 lid manufacturing process
1, the circular top open end of the manufacturing process
Top lid that has strengthened sheet by stamping round or profiled corrugated cover, open cans when cut with a special tool .
Circular top lid manufacturing process line as follows:
① cutting board
② punch cover rounded edges
③ dispensing and drying


2 , easy open manufacturing process
( A ) Classification of easy open end

① pick the size of the opening
② pick the materials of
③ then open the way points

( 2 ) the performance requirements for aluminum alloy
( 3 ) easy open end of the manufacturing process and equipment
① easy open ring pull production process
② base cover production
③ finished cover
( 4 ) technical requirements for easy open

① basic dimensional inspection
② The main performance
③ appearance quality requirements
④ coating quality requirements

( 5 ) Quality inspection methods

① EOE compressive strength test
② EOE tightness test ?

4.4 determine the metal cans cans , structural
( A ) the factors that affect the cost
( 2 ) shall meet the packaging requirements of the inner packaging
20 ℃ tank capacity is the volume of the metal cans , to be deducted when calculating the tank bottom and lid height.
4.5 cans selection of raw materials
Should be based on the structural strength of the metal tube to determine the material and thickness. Sheet metal pipe used in a thickness of about 0.15 ~ 0.5mm.

( 1) The thickness of the material should be determined based on the structural strength of the metal canister to determine the canning material

( 2 ) calculation of the area of materials
