The finished products of liquid silicone rubber and solid sillicone are not easy to distinguish. Here are some reference choices how to silicone injection molding design guide Manufacturing?

    1. Material appearance
    Liquid silicone rubber is in a liquid state and has fluidity; normal silicone is solid and has no fluidity.

    2, Application areas
    ①liquid rubber silicone is generally used in baby products and kitchen & medical supplies.
    ②normal silicone is generally used in daily necessities and industrial miscellaneous items as well as auto parts.
    ③The safety of liquid rubber silicone is higher than normal silicone - liquid slicone rubber is a food material with high transparency and high safety. It is not added with auxiliary materials such as vulcanizing agent during molding, and it is FDA/LFGB compliant and has direct access to food and the human body.

    3, Material properties for silicone injection molding design guide

    ① liquid silicone rubber properties

    ②solid silicone properties

   3. Forming process
    ①liquid silicone is injection molded. when liquid silicone rubber moulding started, the barrel of the injection machine is extracted from the A and B groups at a ratio of 1:1 and thoroughly mixed. they are injected into the mold through a vulcanization screw at a mold temperature of 170-200 ° C. the liquid rubber sillicone part comes out in the mold.

    ② solid silicone part is compression-molded, and after being kneaded by raw materials, it is cut into a size and thickness suitable for molding, and then placed in silicone mold, manual demoulding.
