What's the raw material for making rubber molds? Just rubber
Business model: the deployment of a good material, pour in the imitation of the clean kind. In order to save materials, prepared mold thinner, can also be divided. In order to increase the tension of the mold coating can paste gauze at 20 degrees. Such conditions at room temperature for 2 hours can be cured elastomers, after a day can use.
Using special silicone rubber mold, the product line is sold in two forms of packaging, A component is a rubber material, the B component is prepared. The catalyst should be taken into account when the room temperature, mold strength and hardness, in order to determine the component AB weight ratio. At room temperature at 20-25 degrees, A:B=100:1.5. room is low (but not less than 10 degrees), the increase of B component 0.1-0.3. High B group 0.1-0.3 decreased at room temperature. The specific method is to determine the total amount of mold volume, then the A and B components according to the proportion of accurate weighing, placed in containers in stir, serve.
Rubber mold is one of the most simple method in rapid tooling, is generally used RP silica gel prototype mode, but life is very short, only about 10-30! He has good elasticity and reproduction performance, with silicone rubber mold can be copied without considering the draft, will not affect the dimensional accuracy of segmentation well, not on the die can be directly integralpouring. Then along the parting line for cutting out predetermined mold on it!
