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 SENDA have the following characteristics: SENDA 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.
SENDA'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.
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.
