2 part silicone for ceramic mould making

China is the largest and traditional producer of ceramic, which is rich in clay resources. Ceramic products are involved in people's life and production fields. This question that how to make the ceramic products is worth thinking over when you see them in production and life. In the first place, you need to create a ceramic mould for production in large quantity and 2 part silicone for ceramic is the best raw materials for ceramic mould making.   Why do I say 2 part silicone for ceramic mould making is your optimal choice. The purpose of ceramic mould making is to improve the production efficiency and cost savings. Then, silicone for ceramic with high cost performance is favored by the customers than other material, for example, plastic ceramic mold has low cost, but not durable.    Advantages of 2 part silicone for ceramic: 1. Production process is simple, requiring only a few steps, and you can make the ceramic mould by yourself easily even if you've never been exposed to this. 2. 2 part silicone for ceramic possesses these features of excellent flow properties, low shrinkage, high number of rolling over, high degree of simulation, high temperature resistant, acid and alkali resistant and ageing resistance, etc.     Next, taking Chinese blue and white porcelainas an example, please follow me for ceramic mould making step by step: 1. Prepare some appropriate operational tools, such as ruler, board, vacuum machine, brush, electronic scale, etc. 2. Select a perfect and exquisite blue and white porcelain model after this procedure of cleaning and burnishing.  3. Normally we suggest that this model is made into two pieces in order to avoid the problem of parting mold line.  4. Pile up the clay under the mold line. The hardness of clay is moderate, and there is no gap between the sludge and model. Then, dig some holes evenly on clay to make latch. 5. Choose a high quality 2 part silicone. Here, we select HY-625 silicone for ceramic with the hardness of 23-27 shore A, then add 2% catalyst into 2 part silicone of 100g. The mixture is well stirred and discharged from bubbles. 6. Brush the first layer for 1 mm and the second for 2-3 mm after the first one of 2 part silicone comes to cured. 7. You'd better put a layer of gauze before you brush the third and fourth layer of silicone for ceramic in order to increase the tensile and tear strength of the ceramic mould. 8. After the 2 part silicone for ceramic cured, the gypsum outer mold can be made. 9. Pour the prepared plaster into the frame. 10. Release the ceramic mould when the plaster is curing. Then, the process of ceramic mould making has been finished. 11. Keep ceramic mould for 24 hours before use to be able to effectively increase the duplication times. Because the crosslinking and density of 2 part silicone for ceramic is closely related to the time. The crosslink density is a little small but fast growth at an early stage, which tends to be stable after 24 h and the vulcanization reaction really is completed at this time.   Shenzhen Hong Ye Jie Technology Co., Ltd. with high-tech, the best service, high qulity products with competitive price and the vast international market is worthy of the leader of 2 part silicone industry.
