Home Appliance Sheet Flying Cut To Length Line for PPGI Steel Coil
Home appliance steel sheets are pre-painted galvanized steel sheet
(PPGI) sheets or surface laminated sheets, require high
precision rapid flying cutting to length machine, for the finished
sheets are narrow and short, the cutting frequency must be hundreds
of pieces to give enough productivitity,
Household appliance sheets covers about 31% of PPGI
Sheets after application of construction(63%), it has advantages:
light, good looking and anti-corrosion(50% longer time than GI
sheet).
Home appliance PPGI sheet coil specification:
| thickness | width | coil ID | Sheet length | coil weight |
| 0.3-2.0 | 500-1550 | 508/610 | 500-4000 | 5T -15T |
Characters:
- 1/ finished sheets must be very flat without stress bending,
- 2/ finished sheets must be very clean without roll marks,scratches
or dirty matters
- 3/ lengths and widths of sheets vary a lot, sometimes very narrow
or very short.
- 4/ Length tolerance, diagonal length tolerance must be very precise
- 5/ frequency and speed of cutting must be fast enough.
With the above characters, our rotary shear fly cut to length line
is good solution to cut good appliance steel sheets.
We supply such high speed cut to length lines to Algeria and
domestic customers in Changzhou.
