Features of silicone rubber for making molds: 1. Good characteristics of easy-operation 2. Light viscosity and good flowability 3. Low shrinkage 4. Favorable tension 5. No deformation 6. Favorable hardness 7. High temperature resistance, acid and alkali-resistance and ageing resistance Operations of silicone rubber for making molds: Step One: Take 100g of part A and add 2g of part B and mix the silicone 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 is 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 , and no more further steps will be available Step Two: vacuum pumping Without exception, this step takes less than 10 minutes. Otherwise, it will cause , and no more further steps will be available Step Three: Perfusion Molding The perfusion molding is an easy way to make molds, it is Slowly and evenly perfuse the mixed silicon rubber into the square frame 25kg per drum.200kg per drum
E flowing liquid with general hardness of 22-50aafter curing with features ------ s than 10 minutes. Note: the time for vacuum-pumping should be less than 3a5 minutes , otherwise, once the silicone rubber has cross-link reaction during vacuum pumping process, it will not be operated. Step three: brushing cast & perfusion molding operation Shelf life for silicon rubber for mold making 10~12months, when stored in a dry & cool place under the room temperature 25. Faq silicone rubber for mold making: Why is the silicone mold oily? The molding silicone rubber itself doesn't contain any oil, so it won't be oily. If the mold is oily, it may because you add compound silicone oil which is the compound of silicone oil and white oil. But the white oil is not silicone oil but a kind of petrochemicals.

For example, take silicone rubber of 100g and add 2% curing agent for mixing evenly. After the silicone rubber and the curing agent are completely mixed, put the silicon into a vacuum machine for deairing to remove the bubbles. After deaired, pouring the liquid silicone rubber into the product to be duplicated or into the mold frame. LIQUID RTV-2 SHOE MOLD SILICONE RUBBER NOTES: Shoe mold silicone rubber is used for pouring or brushing technique. That is to say, fix the product or sole model to be duplicated onto a plane plate, then enclose the plane frame with wooden plates to prevent the leakage of the silicon , mix the silicone rubber and the curing agent evenly according to the mixing ratio of 100 : 2 and pour them onto the sole model, then brush evenly with a wooden plate or a brush, and fill up the mold frame with gypsum after the silicone rubber is dried. 20 KG/drum
