Tips

 

Q: How many kgs of silicone I need to make a mold, like 1m*1m?

 

A: First, you change the "m" to "cm". Then the V(volume)=100cm(length)*100cm(width)*1.5cm(height or thickness) =15000cm3

→ the density of the liquid silicone is 1.1g/cm3→ the quantity= 15000cm3* 1.1g/cm3=16500g(16.5kg)

 

 

Q: How can I know the thickness of the silicone mold?

 

A: For the pouring way, if you do not have a plaster have a base to keep its shape (like square), then we usually suggest that 2-3cm is enough. If yes, then 1-1.5 cm is enough.

 

Q: Why is there not enough 25kgs silicone in the drum?

 

A: V=m/p. because the different of the silicone viscosity, so there will be a little difference. When the viscosity is lower, there will be 26kgs or more. In contrast, there will be 24kgs or little.
