The instruction of Creasing matrix

1. First Measure the creasing rule length of the die making boarding.

2. Cut the creasing matrix according to the measuring length，and cut the two ends naturally into 90 degrees sharp angle.

3. Fix the elastic opening of the positioning strip of the creasing matrix to the creasing rules.

4.After the creasing matrix is all clamped，tear off the bottom protective adhesive tape.

5. The die-cutting machine will be installed to start the die-cutting machine once，the creasing matrix is located on the bottom die plate.

6.Tear off the creasing matrix positioning strip，creasing matrix indentation die positioning completed.

How to choose the correct creasing matrix style？

In the process of die-cutting，different types of paper should choose different specifications of creasing matrix，which Paper jam and corrugated cardboard have different selection methods.

 a=creasing matrix thickness

 b=groove width of the creasing matrix

c=paper jam thickness

d=creasing rule thickness

e=the flatten corrugated cardboard thickness

a=c b=(c×2)+d

First，measure the thickness of the paper jam with a caliper.The thickness of the creasing rule selected for die-cutting should be greater than or equal to the thickness of the paper，and the groove depth of the creasing matrix should be equal to the thickness of the paper.

In production practice，the groove width of the creasing matrix can be selected according to the following formula：

*creasing matrix groove width = paper jam thickness×1.5+creasing rule thickness.

a=creasing matrix thickness 

b=groove width of the creasing matrix

c=corrugated cardboard thickness

d=creasing rule thickness

e=the flatten corrugated cardboard thickness

a=c b=（c×2）+d

First，measure the thickness of the flatten corrugated cardboard with caliper.Choose the thickness of the creasing rule is greater than or equal to the thickness of the flattening corrugated cardboard. The groove depth of the creasing matrix（the thickness of the creasing matrix） should be equal to the thickness of the flatten corrugated cardboard.

In production practice，the groove width of the creasing matrix can be selected according to the following formula：

*creasing matrix groove width = the flatten corrugated cardboard thickness×2+creasing rule thickness.
