Plastic crafts mold making rtv silicone

Plastic crafts mold can be made by many kinds of materials, such as plastic, mold making rtv silicone, resin, and gypsum and so on. Then, why do most people prefer to choose plastic crafts silicone to make molds? What's unique features the mold making rtv silicone holds and how to make plastic crafts mold using it? Today, I'm going to share these questions with you.   Plastic crafts mold making rtv silicone has good simulation, good strength and low shrinkage. The production process of plastic crafts mold made with rtv silicone is very simple and does not require special skills and equipment, which can be vulcanize just a few hours under room temperature. Plastic crafts silicone molds can withstand repeated use and poor operation and can be directly processed into complex shape crafts, eliminating the milling and polishing process and other processes. The mold making rtv silicone is also very easy for demoulding. In addition, the plastic crafts silicone mold has good flexibility and elasticity, so, it can be removed directly after completion of the casting for those plastic crafts with complex structure, fine pattern and without stripping slope, which is unique compared to the mold made by other raw materials.     Next, taking plastic vase as an example, please follow me for making plastic crafts silicone mold step by step: 1. At first, prepare the tools required for operation and an exquisite plastic vase mold species.   2. Draw the parting line to make the plastic vase easy to demould. The location of parting line is positioned at its highest level of plastic vase, and the line should go from the obvious binding site and bypassing the important parts and fine patterns.   3. Fasten the model to board and stacked with clay with appropriate hardness.   4. Here, we select the plastic crafts mold making rtv silicone of HY628 because the structure of plastic vase is simple and its' size is moderate. Mix 100 g plastic crafts silicone and 2 g catalyst uniformly, then, take the mixture to vacuum to avoid the surface of mold remain particles affecting the the quality of plastic crafts silicone mold.   5. Next is the brush molding process. Brush the first layer of mold making rtv silicone about 1 mm and the second layer should be brushed after 15 minutes about 2 mm. Then, A layer of gauze is needed at this time to enhance the strength and tear resistance of mold making rtv silicone before you start brushing the third and fourth layer of plastic crafts silicone.   6. Take out the mold when the mold making rtv silicone is wholly cured. Next, you need make a resin outer membrane in order to prevent the plastic crafts silicone mold from deformation.   7. When the outer mold cross linking reaction goes on, clean out the sludge and trim edges.   8. Repeat the above steps to create another piece of plastic vase mold. Till now, the perfect plastic crafts silicone mold has been done.
