Molding Silicone Rubber For Candle Molds
1,Description of Molding Silicone Rubber For Candle Molds :
RTV silicone rubber are generally named as two-part room temperature sulfurated silicone rubber, which features an exceptional fluidity and good operability. When mixed with 3% curing agent, they can still be operated within 30 minutes, but will be formed after 2-3 hours. With resistance to deformation, high temperature, acid and alkali, and expansion, silicon flexible molds are used for mold duplication and delicate mold making for poli crafts, resin crafts lighting and candle crafts.
2.Features of Molding Silicone Rubber For Candle Molds :
1 Two part of liquid fluid: liquid white silicone and curing agent.
2 Cure at room-temperature within 4-8 hours, but all performance will act perfectly when it cure within 24 hours.
3 Good fluidity and excellent operation.
4 Good resistance to weather, temperature, aging, acid..
5 Excellent tear strength, comfortable duplication times.
3. Process operations of Molding Silicone Rubber For Candle Molds :
Liquid silicon molds are the least expensive and fastest way to create about a dozen prototype parts. Even with undercuts, the part is able to be removed through distortion of the mold.
a. Process and prepare the model mold or the product to be duplicated,
b. Take certain amount of the silicon rubber, add 2-3% solid curing agent, and mix evenly and they are ready for use.
c. Once cured, the RTV is removed from the vat and separated from the pattern and parting line surface to yield the two halves of the molding tool. RTV air-cures, so that the cure time depends on the geometry, the RTV type, and the environment. Cure time can range from .5 to 40 hours. Aging of the mold after cure for up to three days can improve mold life.
4.Frequently asked questions of Molding Silicone Rubber For Candle Molds :
What should we do when the air bubbles appeared in the process of mold making ?
To handle this situation depends on different cases. Under the condition of an available vacuum pumping machine, mix the silicon rubber and curing agent evenly and then take it to vacuum chamber to deair. If without a vacuum pumping machine, reduce the amount of the curing agent properly. For example, change the mixing ratio of the silicon rubber and the curing agent from former 4% to 1%-2%. In this way, the pre-crosslinking time of silicon rubber will slow down, so the air in the mold will be eliminated gradually to reduce the air bubbles.
