1. Foam forming is to pre-foam EPS/EPO/EPP plastic raw materials into particles, and then the particles are sent to the mold, heated by high temperature steam, squeezed tightly, and the surface of particles bonded to each other into a whole.

2. You can't do it without foam injection molding machine. You can only use plate to cut and process, and the surface will not have skin, which is not very smooth.

3. Foaming rate is the plastic raw material from small particles into large particles, the volume ratio is about the inverse of its density, such as the foaming multiple is 50 times, the density is 20g/L, the greater the rate, the smaller the density, the lighter, but the smaller the strength.
