Molding Silicone Rubber for Prototyping Making Date:2017-02-09


Applications for Molding Silicone Rubber for Prototyping Making:
        • Rapid prototyping (urethane casting/silicone tooling/vacuum casting)
        • GRC and concrete molding
        • PU resin casting
        • General mold making
        • Food grade molding application, food safe mold making.
Description of Molding Silicone Rubber for Prototyping Making:

        HY-Q series food grade silicone(also medical grade silicone) is composed of two parts. Part A is a flowable liquid, part B

is the curing agent (platinum catalyst). It features an exceptional fluidity and good operability. Because of its high transparency

and high tear strength, it is always used for prototyping and all kinds of food mold.


Characteristics of Molding Silicone Rubber for Prototyping Making:

        - Almost nil shrinkage
        - High chemical resistance to aggressive components of some types of resins
        - Strong tear strength (this feature ensures higher resistance to wearing and shearing)
        - High degree of precision in reproduction
        - High dimensional stability over time and non-deformability
        - High resistance to high temperatures and ageing (resist to -60 to 200°C)
        - Fine surface without being sticky.
        - Food grade, FDA approved (environmentally friendly, odorless and nontoxic)
Notice of Molding Silicone Rubber for Prototyping Making:

        Hardness is not fixed, you can adjust it in accordance with your actual situation and needs. (silicone oil can not be add

too much, otherwise the quality will be ruined)
Operation instructions of Molding Silicone Rubber for Prototyping Making:
        1. Clean the model and molding tool completely before operation to prevent cure inhibition and guarantee flawless quality.
        2. Weigh out silicone material appropriately.
        3. Mixing the two parts in 1:1/10:1 and stir part A and part B thoroughly to form a kind of even and uniform mixture.
        4. And get the mixture for vacuum-pumping for de-air the bubble in around 2-3 minutes. (If there is no vacuum machine,

pour the mixture carefully and slowly down the side of the mold frame in case of producing bubbles).
        5. Enclose the product (the original model) with four plastic plates or wooden plates.
        6. Clean your products and brush a layer of release agent (detergent or soap water) on your product.
        7. Pour the vacuumed mixture into the model frame from the side of the mold frame.
        8. When curing time is arriving, a FDA approved silicone mold is finished.
