EVA characteristics: EVA rubber and plastic products are new environmentally friendly plastic foam materials, which have good buffering, shock resistance, heat insulation, moisture resistance, chemical corrosion resistance, etc., and are non-toxic and non-absorbent.
EVA main purpose: for the production of refrigerator ducts, gas pipes, civil plates, containers and daily necessities, etc., can also be used for packaging films, gaskets, medical equipment, can also be used as hot melt adhesives, cable edge layers. At present, in the solar cell industry, the cell sheets in the crystalline silicon battery are bonded to the surface photovoltaic glass and the battery back sheet.
The characteristic of the EVA machining cutting machine is that 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 time of contact (cutting into the workpiece) increases. Until the electromagnetic 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 time limit of the pressure oil entering the cylinder; That is to say, the system pressure has not reached the design value, and the die cutting has been completed.
The scope of use of cutting machine: suitable for foam materials, cardboard, textiles, plastic materials, leather, rubber, packaging materials, flooring materials, carpets, fiberglass, cork and other non-metallic materials through the die to achieve the material by the pressure generated by the machine Punching and cutting.
