How to cut foam and sponge?
If you use a hot wire to cut, can be an easy job to do to implement, just like a knife like tofu, if the speed master well will not affect other parts of the shape, therefore, we use the hot cutting processing method of foam and sponge is a kind of ideal method (factory by hot plastic injection method is another matter).
As for the sponge, a little pressure on the deformation, and the knife, cut processing will inevitably put pressure on the material, the material deformation, to cut the number of difficult to grasp, so use cutlery processing sponge to get good work is more difficult. But foam and sponge have a common characteristic, that is, the heat is easy to melt, and the heat is the bad conductor.
Foam plastics and sponges usually give a definite shape, which is what we need to take advantage of. Although the foam can withstand deformation without some pressure, but the surface forming machining knife, sawing is often not smooth, but is not the only cutting scissors, with very sharp blade cutting and processing of small plane and plane and curved blade slightly larger is incapable of action.
