Sponge is a porous material that has good water absorption and can be used to clean items.
The commonly used sponges are made of wood cellulose fibers or foamed plastic polymers. In addition, there are natural sponges made from sponge animals, most of which are used for body cleaning or painting. In addition, there are three types of synthetic sponges made of other materials, namely low-density polyether (non-absorbent sponge), polyvinyl alcohol (high-absorbent material, no obvious pores) and polyester.
The characteristics of the sponge cutting machine: When the punching head acts on the workpiece through the die, the pressure in the working cylinder does not reach the rated pressure, and the pressure will increase as the contact (cutting into the workpiece) increases, until the electromagnetic The reversing valve receives the signal, the reversing valve is reversed, and the punching head begins to reset; at this time, the pressure in the cylinder may not reach the set rated pressure value due to the limitation of the time of the pressure oil entering the cylinder; The system pressure has not reached the design value, and the die cutting has been completed.
Honggang's sponge cutting machine is roughly divided into three types: one, the ordinary manual cutting machine, the second, the automatic feeding cutting machine, and the third, the automatic feeding cutting machine for the coil.
