20-Nov-15S.Movchan Straw manufacturing and QC1 Straw machine status straw fabrication option 1: removing metallization from tape edges by laser study straw #3678: results conclusion straw fabrication option 2: moving anvil study straw #3675: results conclusion Presented by S.Movchan
20-Nov-15S.Movchan Straw manufacturing and QC2 Straw #3678 : F=200 gram + P=50 a.u. V=10 mm/sec first 13 samples (10 cm each) of straw are fabricate from tape without metallization on it edges (removed by laser) samples 14÷29 are fabricate from standard tape check seams by microscope: zoom x 200, transmit light
20-Nov-15S.Movchan Straw manufacturing and QC3 Tape with removed metallization from both edges by laser 0.5 mm
20-Nov-15S.Movchan Straw manufacturing and QC4 Straw #3678 Sample #
20-Nov-15S.Movchan Straw manufacturing and QC5 3 seam types: zoom x no metallization: PET+PET welding 2. Cu+Au metal+metal welding 3. PET+PET and PET+metal welding
20-Nov-15S.Movchan Straw manufacturing and QC6 Very good seams (dL>9 mm): zoom x 200 Sample #1 Sample # mm
20-Nov-15S.Movchan Straw manufacturing and QC7 Very good sample #10: dL=10 mm (zoom x 60) After seam brake
20-Nov-15S.Movchan Straw manufacturing and QC8 Good seams (dL>4 mm): zoom x 200 Sample #6 (dL=4 mm) Sample #8 (dL=9 mm)
20-Nov-15S.Movchan Straw manufacturing and QC9 “Bad” seams (dL<1 mm): zoom x 200 Sample #5Sample #7
20-Nov-15S.Movchan Straw manufacturing and QC10 1) Preliminary: laser don’t make worse seam quality 2) 3 types of seam: PET+PET, metal + metal, PET + metal 3) Very good seams are without metal particles inside seam ) Difference between good seams (samples #6 and #8) and bad seams (samples #5 and #7) in case when metal exist inside seam is unobvious
