Many people like to use silicone to make some models, such as DIY handmade soaps, cartoon character models, etc. So what tools and materials are needed in the process of turning the molds? Here is a list to share with you.

1. Liquid silicone rubber
Liquid silicone rubber is the main consumable for making silicone molds during the mold turning process. There are two types: translucent and white. It is recommended to use the white one. Its fluidity and number of mold turning times are better than that of the translucent one.

2. Curing agent
Curing agent Curing agent is to solidify liquid silicone rubber. Add silicone rubber in the proportion required by the manufacturer, stir thoroughly and cover the mold. If too much curing agent is added, the silicone rubber will harden quickly and may be scrapped before the operation is completed. Add too little and the curing time will be long or it may not cure at all.

3. Polyurethane resin
Polyurethane resin, commonly known as AB water, is a very convenient material to use. Mix the AB components at a ratio of 1:1 and mix thoroughly. It will start to solidify in about 3 to 5 minutes. Wait for 1 hour for complete solidification before demoulding. The molding details are very good, the shrinkage rate is small, and the finished product feels good.

4. Release agent
The release agent can be sprayed, or you can use medical Vaseline instead, or you can use eye ointment and other oily things instead, in order to separate the silicone mold.

5. Industrial rubber clay
Industrial plasticine is the main material used to make reflective molds before pouring silica gel. It is relatively soft and can be replaced with oil sludge, mesh soil, etc. It can be used repeatedly and is often used when turning over a large number of molds.

6. Building blocks
Turnover building blocks are not necessary. You can use ABS board or cardboard to build them. Just pay attention to the sealing. If the cardboard surface is smooth, it will be fine.

7. Electronic scale
Electronic scales are used to weigh the weight ratio of silicone to curing agent.
