Silica gel mold is a kind of container with cavity made of silica gel as raw material. In most cases, liquid materials (including epoxy resin, polyester and polyurethane resin, wax, concrete, soap, etc.) can be cast into the cavity, and then cured to make mold cavity shaped objects.
Silicone mold is usually made of a material called room temperature vulcanized (RTV) silica gel. RTV silicone consists of two parts. It is a simple material, soft and fast curing. After curing, the silicone will remain flexible and elastic, but it depends on the hardness of the rubber you choose to use. If stretching is excessive, the silicone may also tear or crack.
Silica gel mold is a special mold for making handicrafts. The raw materials of rubber tools can be divided into ordinary silica gel and meteorological silica gel according to their performance. Silica gel is characterized by high temperature resistance, corrosion resistance, strong tear resistance, and fine simulation. It is a mold for making various handicrafts. Silica gel is more and more popular because of its good environmental performance.
1. Common silica gel, also known as precipitated silica gel, is mostly used for mobile phone buttons, miscellaneous pieces, conductive adhesive and other low-grade silica gel products; Weather glue is also known as pure silica gel because of its good transparency, tensile resistance, strong silicone rubber tube, protective sleeve and other high-end products that need high elasticity.
2. Silica gel raw materials can be divided into solid silica gel and liquid silica gel according to their physical properties.
Solid silica gel is mainly used for molded products. For example, silicone covers, silicone tableware, silicone molds, silicone buttons, etc. Liquid silicone is mainly used for extrusion products, such as silicone pacifiers, silicone tubes, etc.
Thermal insulation silicone pad, excellent high temperature resistance, silicone (food grade silicone) can withstand 200 ℃ high temperature and can be used for a long time. The raw materials of this product meet the food grade standards, pass the FDA food grade detection, tasteless and non-toxic. The manufacturer can produce according to the model, and the color and shape can be determined by itself.
Advantages of silicone mold
1. Easy to use.
2. Small details on the model can be copied.
3. It does not stick to the mold and has excellent demoulding performance.
4. Good acid and alkali resistance for most chemicals.
5. It has excellent tear resistance and can be used repeatedly.
6. It can be used in the temperature range of - 50 to+250 ° C.
Silicone mold has a wide range of applications, from professional quality vacuum casting of prototypes to small batch wax casting for jewelry production, to home applications such as baking and candy production, and can be used to copy figurines, jewelry, artifacts, collections, candles, etc.
