The Characteristics of Manual Mold Making Silicone Rubber

Detailed information about manual mold silicon:

Manual mold silicon series are all free-flowing liquid. No matter what the color is, its quality is permanent. Component A is flowing liquid and Component B is catalyst. We should at first dispose the original mold well and prepare appropriate amount of silicone rubber, then add 2%-3% catalyst into it and stir the mixture evenly, after all the operation finished, the manual mold silicone rubber could do the process of perfusion molding or brushing molding. The manual mold silicon can cure after 2-3 hours. We’d better put the final manual mold into practice after 24 hours. MC manual mold silicon merits the customers’ trust, because it possesses the characteristics of no deformation, no shrinkage, high temperature resistance and enough duplication times.

The brief manufacture process of manual mold silicone rubber:

Brushing cast:

A. Evenly brush the mixed silicon rubber on the product which is covered with mold spray.

B. 30 min later, brush a second coat which can increase the tension of the mold.

C. Cover a piece of gauze on it after another 30 min of a second cross linking reaction brushes the surface evenly.

D. Cover a coat.

Perfusion molding:

It is suitable for simple products with the smooth surface. Slowly perfuse the mixed silicone rubber into the square frame. After the silicon rubber dries, you could take out the product out. The process nearly finished.

Making external mold

Make a square frame with 4 pieces of wooden boards or rubber plates, then place the product of step 2 in the middle.

Perfuse the gypsum into the square frame.
