1. The water temperature of the thermostatic water tank should be kept at 60 - ° 70 ℃. When the material is completely transparent, it means that it is completely softened, and the molding can be taken out
2. During heating and softening, the material can not be removed from the molding without being completely transparent, so as not to affect the molding effect
3. Do not use too much force or fix too tightly during molding, so as to avoid slight shrinkage of the material itself during cooling and hardening, resulting in discomfort of the patient.
4. During the second molding, the surface stains shall be cleaned, and then heated to soften, and the plate shape can be restored for the second molding. The repeated molding should not be too much to avoid affecting the molding effect.
