First, the knife die uses imported blades:
The rigidity of the knife blade directly affects the cutting effect. For example, the toughness and rigidity of the blade are not enough, and it is impossible to quickly cut the plastic product and obtain a smoother profile.
Second, the choice of steel plate instead of plastic pad:
The traditional plastic backing plate and PP backing plate have certain compressibility and elasticity. The sharp cutting die has no corresponding reaction force when cutting the plastic product, and can not cut a smooth profile. Therefore, the selection of steel plates for cutting plates is particularly important.
Third, select a machine with higher precision:
In the above, the better die is selected and the steel plate is used instead of the plastic plate. The problem that these two problems will be is that the precision of the cutting machine is very high (otherwise, there will be a cut or a knife), which is the most for the cutting machine. The minimum requirements are as follows:
(1) The parallelism between the two worktables is high
(2) Repeatability is high (that is, the pressure is often said to be stable)
