Box Cutting Edges Fluff Reasons And The Choice Of Foam Rubber - Folding Carton Die Cutting, Sponge

Many folding carton plant often cutting edge for the box of paper fluff and headaches

. Is on the paper side of fluff, dust and other phenomena, sub-panels and their causes and treatment for the peer reference.

First paper, we usually use the high quality of the original paper, because fiber is longer, generally more than recycled paper less fluff and dust. So with the original paper will not be easy fluff, dust. However, at this stage, most manufacturers need to reduce costs and promote recycling awareness, more and more people like to use recycled paper. This high quality and reasonable on the growing demand for cutting materials to solve cutting edge of paper fluff and dust problems.

How to choose high-quality materials then to solve the problem? First of all, high quality cutting tool should be used. In general high-grade die-cutting blade, magnifying glass, we can observe that there is still a lot of holes and flaws, that is not very slippery. This is one of the reasons production of paper dust. In particular, ruled handled cutting knife, the surface is very sharp, but in fact particularly large number of defects, the best chance of dust. Now the market has an Austrian BOHLER "Supreme Supreme knife," using a special metal coating, such as wall plaster, as the porosity and defect filling, batch slip, thus greatly reducing the production of paper dust is more suitable for recycled paper. Knife edge with paper to reduce friction, which reduce mechanical wear, the durability of the knife itself more. This knife ideal for cutting pill, cosmetic boxes, food boxes, cigarette cases and requirements such as length version of clean products.

Another box cutting fluff reason is that the supporting strip cutting with the sponge and installation irregularities. Should be sufficient because the hardness of rubber sponge can compress the paper, so that paper cutting knife will cut smoothly. Application of different hardness in different paper sponge rubber, placed in the position and height is also very elegant. Standard installation and material selection are as follows:

Rebound sponge rubber hardness of choice:

1. The distance between the cutting tool such as 8mm, sponge rubber shall be 25 (corrugated paper), or 35 (cardboard) hardness.

3. Knife and cutting the distance between the wires, such as 10mm, then use foam rubber hardness of 35 .

4. Cutting knife used to play mouth-bit arch plastic hard bottom to 70 Shore, used to protect the connection point is not pulled off.

Common sponge rubber of the following:

35 breathable foam rubber: compression rate of 35%, cutting the number of 1,000,000, speed 9000 times / hour for the jam.

20 sealing sponge rubber arch: compression rate of 50%, cutting the number of 250,000 cycles at a speed 7500 times / hour,

Corrugated paper . 60 solid type strip: for narrow spaces, such as cutting knives, this distance 1.2mm. In principle, the more soft sponge rubber, the higher height. Sponge rubber high right kind of wood can produce faster.

In the wooden mold, the number of sponge rubber, hardness and height, should be balanced in every position distribution, the balance should also be arranged on both sides of knife sponge rubber.
