(Summary description)In the prototype model processing industry, in addition to often using plastic materials for processing, it can also be processed with a material called silica gel. The viscosity of the prototype model made with it is very thin and it is very convenient to operate. Its shape is not It will not shrink if it changes, and it is very easy to disassemble. The surface of the mold is very smooth, and the simulation effect is very good. The following briefly introduces the first two processing processes.

In the prototype model processing industry, in addition to often using plastic materials for processing, it can also be processed with a material called silica gel. The viscosity of the prototype model made with it is very thin and it is very convenient to operate. Its shape is not It will not shrink if it changes, and it is very easy to disassemble. The surface of the mold is very smooth, and the simulation effect is very good. The following briefly introduces the first two processing processes.
1. Silica gel is a fluid liquid. Group c is defined as silica gel, and group d is defined as a curing aid. The amount of d added is generally 2% to 3%. For example, take out 100 grams of group c and 2 grams of group d, add d to c, and stir them evenly. If the local temperature is 10 degrees, the number of d can reach up to 5%. And if the local temperature is minus 5 degrees, even if you add more d and c, there will be no reaction, and it will not cure for a long time.
2. The original model or the product to be copied must be processed first, because the copied product or model is not polished. In fact, the model or product is not very smooth, and your mold made of columnar silica gel will not be good. In fact, the poured product is not very smooth.
3. Clean the inner surface of the mold with alcohol, and wrap the silicone mold with tape to make the upper and lower molds completely match. According to the volume of the sample, the weight of the resin is calculated to be 911. In order to ensure that the product is completely formed, take 100g. Weigh 50g each of isocyanate and polyol according to the ratio of 1:1, put the material into the vacuum chamber, evacuate and pour into the silicone mold, then put it into the oven to heat and cure, the obtained physical parts are then inspected by quality inspection , The packaging department will carry out fine packing, and SF Express will deliver it to the customer.
