Product Description

Product Description

A whole set of knife of a slotter machine consitsts mostly of slot knife, bottom knife, spacer, and valve knife. Slotter knife is also called "Sector knife" by manufacturers due to its curved shape.The function of slotter knife is obviously slot folding parts of corrugated cardboard by the teeth which coud be serrated or crescent-shaped.

The key to the slotter knife is the tooth shape and the wear resistance of the cutting edge, which directly affects the cutting quality of the corrugated cardboard. The grooved inserts produced by LCUT have the following characteristics: LCUT has advanced vacuum heat treatment technology, which makes the cutting edge have higher wear resistance than similar products in the market. We use laser cutting equipment to ensure the precision of the product and the tooth profile of the blade. About Custom The finish, parallelism of male and female grooving blades, as well as the edge shape, tooth shape and hardness of open grooving blades all have a certain relationship with the quality of the cut.

LCUT's male slotter knives are used in conjunction with female slotter blades to slot carton board, honeycomb board (three-layer, five-layer, seven-layer) on the printing slotting machine. Our company's slotter blades are possessed with excellent cutting performance, including high durability, precise angle, optimized hardness. In addition, the use of professional heat treatment technology further enhances the durability of blades. Consequently, even under high speed operation, the blades can still maintain the superexcellent cutting strength and stability.

Product Features

1. Forging steel make the inside microstructure become much closer and the metal grain size becomes much smaller to ensure a long working life.

2. Mirror surface finish, polished bevel for minimum friction.

3. Sharp cutting edge, higher precision, excellent cutting efficiency.

4. Longer life between regrinds and higher number of regrind per knife.
