Market which die cutting equipment die cutting efficiency is high

Circular die cutting machine efficiency is higher than flat die cutting, even in the use of different quality paperboard also has a good production and processing effect. Because the circular die cutting with continuous feed, alignment and alignment is also relatively easy to meet the operating requirements. Paper and corrugated board moisture changes have little impact. But there are differences in strength, especially in surface stability. Steel die cutting tools will produce more confetti, but the damage is less, because steel die cutting tools are strong, the impact on the board is greater.

In theory, the die cutting machine made of synthetic materials can easily damage the paper, but when using 100% recycled cardboard, its normal operation time is relatively long, and the production of paper scraps is also very small, but the friction on the cardboard is relatively large.

(1) small mouth mainly open in the direction of paper movement, left and right sides can not open or less open a little.

(2) small mouth should be opened as far as possible on the finished product box can be glued to the inside or folded in the inside part.

(3) if there are incoherent holes in the paper, must be in the die cutting machine version of the direction of the paper on the die cutting knife to open a small hole, so as to avoid the small hole in the waste paper fell on the steel plate, was dragged into the indentation line, causing the product creases broken.

(4) if the paper is thin, the strength of the paper, the opening to less, shallow, narrow is appropriate; If the paper higher expectations, the strength of the difference, the opening is more, deep, wide.

(5) die cutting machine if the finished box box edge is flat, the opening to more, deep, wide, if the finished box box edge is hook, because the paper edge and the finished product will hook each other, the opening can be less, shallow, narrow.

(6) die cutting machine running speed, from the static mold pressure position, the acceleration, the tension is greater, the need for more even point on the printing sheet is not at the top of the broken, the opening also need more, deeper, wider.
