It is an ideal method to make foam and sponge by hot cutting.Analysis of material properties: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.
There is a special foam cutting machine, our company produces this
As for the sponge, a little pressure on the deformation, and knives, cutting processing will inevitably put pressure on the material, deformation of the material, how much to cut, it is 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. 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, with hot cutting processing method of foam and sponge is a kind of ideal method.
