The Application Characteristics of Silicone Rapid Prototyping
By Nice Rapid | Jun 10 , 2020

Silicone prototypes is one of the methods in rapid prototyping, silicone prototype can be divided into two types, one is direct silicone mold and second-time silicone mold. The direct mold making method is to complete the cavity structure through one-time curing and molding of silicone. After curing, the mold is manually cut and divided so that the upper and lower molds are cured separately. Generally, the direct molding method is generally used in practice. 


There are some characteristics of silicone prototypes:


1. Good mold making operability. The soft mold after curing is transparent or semi-transparent, with good tensile strength, easy to cut and type.

2. Good repeatability. The silicone prototype used for molding has good fluidity before curing. With vacuum degassing, it can accurately maintain the detailed structure and decoration of the model.

3. Good mold release. For the reverse slope structure of the model in the direction of ejection, the model can be taken out directly by the elastic deformation of the material.

4. Good dimensional stability of the model. As long as the prototype size of the silicone mold is accurate, the copied product can also maintain the dimensional stability.


Therefore, there are some factors that affect silicone mold prototypes: the performance of silicone, the gate of mold and structure, the size of mold and volume of mold will affect the precision.
