Perfusion/Pouring moulding:
It is suitable for simple products with the smooth surface.Without any mold lines,which helps you save time and is easy for operation.Evenly and slowly perfuse the mixed silicone rubber into the square frame.After the cross linking reaction and the silicone rubber turns dry,you can take the products out.Thus,the mold has been done.
(Note:we usaully use soft silicone rubber to make molds by perfusing,which is easy for demoulding and will not damage the product in the silicone molds.)
Step Five:Operations for the external mold
a. Make a square frame with four pieces of wooden boards or rubber plates, then place the product which is covered with the finished silicon rubber mould in the middle.
b. Slowly and evenly perfuse the gypsum into the square frame. Also you can brush the resin on the product which is covered with the finished silicon rubber mould with a brush or a brush pen. Repeat this process two or three time after the cross link reaction.
