3 Operation of Low Price Mold Making Silicone Rubber Equivalent to DC3481

If the customer wants to make large products and large size molds, the mold should be made ofsilicon rubber for mold making with high hardness. On the contrary, if the mold with fine and precision  patterns, it should be made of silicon with low hardness. The amount of the curing agent depends on the actual requirements of the customer.

Operations  of Low Price Mold Making Silicone Rubber Equivalent to DC3481

Step One: Take 100g of part A and add 2g of part B and mix the silicon rubber and curing agent evenly.

Notes: Moulding silicon rubber is a kind of flowing liquid and it contains two parts. Part A is a kind of white flowing liquid and part B is the curing agent. Remember to mix part A and part B evenly, otherwise the silicon rubber will be partly solidified and this will give birth to difficulties in your final operation. What’s more, the finished moulds will meet a short life. All of these will cause a waste of silicon rubber.

Step Two: vacuum pumping

Without exception, this step takes less than 10 minutes. Otherwise, it will cause cross linking reaction, and no more further steps will be available.

Step  Three: Pouring molding process or Brushing way molding process
