Plastic doors and Windows processing need to fine and fine cross an sample process
Row in the whole sample process plastic doors and Windows processing production process is an important process, it is the role in the form of drawing directly on the profile will technology design intention expression comes out. The operation of the workers should be according to the row is painted, delimit draw wrong will create a huge waste, so that the rise in the cost of processing. The right cross kind, can be a very good control of the doors and Windows processing quality, and can reduce the unnecessary loss.

In the profile should be used for refills of crossed thickness of 0.5 mm pencil in order to wipe redrawing and easy to wipe away after processing. No other applications stroke line, especially can’t wipe not to use the pen to delimit samples.
In the profile cutting for a variety of reasons will cause certain error, so in row when positioning sample, especially some more critical size, both sides should at the same time take measurements and positioning. In the same root profiles in sample on row, can be made of different symbol of different processing content, to operate the workers can confirm. For each row kind of profile root shall indicate code, doors, Windows, number, processing quantity, or so whether symmetry etc. Stroke of good profile general called sample stick, with the whole process flow circulation should be, not the halfway loss, damage or change.
