Operation instruction of making tire mold with silicone rubber

Making a tire is somewhat cumbersome, but it becomes much easier if you have a mold made of industrial-grade tire mold making silicone rubber. The following we will tell you how to make tire mold with silicone rubber.

 Operation instruction of making tire mold:

1. Keep the surface and tread groove of the original tire mold dry and clean.

2. Coated the surface of the original mold with release agent and dried with an air gun. The bottom and the four sides of the tire mold should be surrounded with steel plates, and the inside of these steel plates also need to be applied with release agent.

3. Before the operation of making industrial-grade tire molds, we should prepare appropriate silicone products according to the size, structure, usage and performance of tire mold. Mix and stir the two parts of the silicone rubber well.

4. Then, we should not lose sight of the work of vacuuming to exhaust bubbles.

5. Brush a layer of silicone fluid on the surface including the tank, evenly and meticulously. Then, pour the the mixture fluid slowly along a fixed perfusion points.

6. When the tire molding silicone rubber is cured fully, inject some gypsum water into the steel frame until it filled up the frame.

7. Remove the steel frame after 20 minutes. So far the silicone tire mold is completed.

8. Place the prepared tire mold silicone rubber in the steel frame for making the heart of tire mold.

9. Poured the gypsum water into the steel frame slowly. Place a piece of wood board on both sides of the fast curing gypsum respectively, forming an anchoring groove. The purpose is for the convenience of molding.

10. Insert sheet steel in the lateral pattern groove of the completed plaster mold’s heart.

11. Connect eight gypsum mold into a circle, which is made by the same method described above. kerosene sawing into the mold heart and then the heart of tire mold has been finished so far.

12. Placed the gypsum outer mold which is made for the time making silicone mold in outer core. Then put the outer mold and the heart of mold on the steel plate. The gypsum core should be heated to even 600 degrees and be injected of liquid aluminum alloy. Wait for its cooling and being solid after filling.

13.Remove aluminum alloy tire and place it on the tire rims machine for correction to make it in accordance with the standards.
