There are many kinds of molding methods for silicone kitchen utensils. The most commonly used is molding, also known as molding silicone products. In addition to molding, it must be supported by corresponding molds. Mold, vertical mold, etc.), injection molding and overmolding three methods, the points involved are different.
One is to surround the mold with plastic boards or wooden boards, and then fill the mold cabinet with gypsum; the other is to use resin brushing method, first apply a layer of resin, then One layer of fiberglass cloth, apply it again, and then paste two layers of island and three layers. It should be noted that the sheet mold is relatively easy to deform, so an outer mold is generally made to prevent the deformation of the mold. Injection mold, a silicone product with a simple structure and a smooth surface, is more suitable for reproduction in this way.
Method: first surround the mold with silica gel or glass plate, take a certain amount of silica gel, curing agent, stir evenly, then pour the extracted silica gel, after the silica gel is dry, take out the product, and the silica gel mold can be completed. Injection molding molds generally use silicone materials with softer hardness to facilitate easier demolding without damaging the internal parts. Brushing the mold, which is layering (usually three layers) inside the mold, brushes out the silicone. When brushing the first layer, the middle mold must be placed in a vacuum state, and the edges and corners should be fully brushed. The second layer should be covered with gauze. When brushing the third layer, the silicone must be brushed, and then brushed after curing.
When using the brush mold method, the release agent (or release agent) should be applied to the product or model to be copied first, and then a certain amount of silica gel and curing agent should be taken, transported evenly, and evacuated (not too long). After applying the silicone, wait for about one vanilla and the encapsulation reaction will occur. After the silica gel is dried, it is used as the outer film. The silicone product is not static. In the process of its development to today, there have been many classic works. These works are in the hands of the designer. In the continuous market development, the high-quality products will surely be obtained. Recognition of consumers, silicone molds will also follow.
