Wallpaper knife tried, the effect is not very good, I do not know what tips can be cut foam, as far as possible, less ball ball!It's that kind of thinner foam, such as styrofoam in a computer boxThank you
You can use electric wire cutting.The first, first bidirectional silicon controlled voltage regulating circuit boards can be disassembled by the waste light regulating desk lamp or made by themselves;Second, first suitable transformer, primary 220V, secondary 12-36v power can be, can not be too small to secondary rated current more than 2A is appropriate, I used a 220v/24v, 100W, the secondary current is about 4A, the secondary current point is conducive to the use of electric heating wire thicker, tensile point. The voltage regulating circuit and transformer mounted on a wooden box in 220V, power regulating circuit, whose output is connected to the transformer 220V side, transformer secondary is connected with the two terminals or rose as a low voltage output.Third, heating wire, electric wire available waste, according to the transformer secondary current selection of suitable electric wire, cutting material size according to the appropriate length of interception of vertical tension (can be fixed according to their own circumstances such as a stent), both ends of the transformer secondary wiring to, from low to high output voltage can be cut to the right.Benefits: electric wire can be selected according to the length of processing materials, adjust the voltage, so that the temperature is suitable for cutting can be, - it should not be too high, so as to avoid electric wire break
Hello, you can find a more suitable resistance wire, with 3-24V/2A adjustable power supply, the foam block to be cut in the limited barrier plate positioning, you can cut according to the required size. Or you can use heating wire and waste electric stove wire.
