candle crafts mold silicone

. Silicone for candle crafts
. . Uses of silicone for candle crafts:
.
.
. . Candle crafts, wedding candles, candle flowers, craft candles and other mold manufacturing, and also It can be used in the manufacture of resin crafts, unsaturated resin crafts, gypsum crafts, gypsum dolls, and patterned fine molds.
.
..Selection of silica gel for candle crafts:
..According to the operation method, if it is a pouring mold (wrapped mold), the hardness can be < r< degree or
.
. . Degree of silica gel, specifically:
.
. .< Degree of hardness silicone mold characteristics: small crafts, low viscosity, good fluidity, easy to operate, easy to release bubbles, It has good tensile tear strength and is easy to pour.
.
.
. .Features of hardness and hardness mold silicone: making large products, low viscosity, good fluidity, easy to operate, easy to release bubbles, good tensile and tear strength, easy to pour.

..How to make silicone molds for candle crafts
. Add curing agent< r.< Stir thoroughly and set aside.
.
. . < r< , treat and lubricate the master mold blank with release agent.
.
. . < r3< The lubricated mother blank is surrounded by wooden strips. The wooden strips should also be treated with release agent, and the gap in the middle should be < r<.
.
. . < r< . Slowly pour the prepared glue along a fixed pouring point, and shake it from time to time to eliminate the air inside.
.
. . < r< , < r< After the glue is completely cured, surround it with wooden strips, leaving a < r< gap, and remove the original wooden strips.
.
. . < r<. Mix the gypsum powder < r< with water and then pour it into the wooden frame until it is full (the wooden frame should be divided into two parts with plastic sheets to facilitate mold removal).
.
. . < r< , < r< After a few minutes, remove the wooden strips and the mold will be completed.
.
. . Note:
.
. . < r< The amount of curing agent added should depend on the temperature. If the temperature is high, it will be reduced. If you use too much curing agent, the mold will become hard and brittle. If you use too little curing agent, the operating time will be extended.
.
. . < r< . In order to prevent the physical properties of the mold silicone from changing, it is recommended not to add silicone oil.
.
. . < r3< . In order to achieve the best use of your mold, please store the mold for at least < r< hours before use.
.
. . < r< The hard mold can also be made of resin.
.
..How to operate silicone for candle crafts:
.
.
. . < r< Stir the silica gel and curing agent evenly< r. The appearance is a flowing liquid, the < r< component is silica gel, and the < < component is a curing agent. Example: Take < r< grams of silica gel and add < r< grams of curing agent (Note: The silica gel and curing agent must be stirred evenly. If not stirred evenly, one part of the mold will be cured and the other part will not be cured, and the silica gel will not dry and solidify. Uniform conditions will affect the service life and the number of mold turnovers of the silicone mold, and even cause the mold to be scrapped.
. Finally, carry out vacuuming to remove bubbles. The vacuuming time should not be too long. Under normal circumstances, it should not exceed ten minutes. If the vacuuming time is too long, the silica gel will solidify immediately, resulting in a cross-linking reaction, which will turn the silica gel into pieces. , it is impossible to paint or pour, so the silica gel is wasted. You can only pour the silica gel into the trash can and use it again.
.
. . < r3< , painting or operation process : Pour the evacuated silica gel with air bubbles removed by brushing or pouring it on the product (Note: before pouring the silica gel, the product or model to be copied must have a release agent or isolating agent). Then apply the silica gel Brush it on the product, and the brushing must be even. After < r3< minutes, paste a layer of gauze fiber cloth to increase the strength and tensile force of the silicone. Then apply a layer of silicone, and then paste a layer of gauze fiber cloth, so that the two It is enough after one time. Only by doing this, the service life and the number of mold turning times of the silicone mold will be relatively much improved, which can save costs and improve efficiency.
.
. . < r< , outer mold Production: The generally used methods and materials are to surround the mold with plastic boards or wooden boards. Once the mold cabinet is filled with gypsum, the other method is to use resin painting. Apply a layer of resin. Paste a layer of fiberglass cloth, then brush and paste again, repeat two or three layers to complete the outer mold of the mold.
. The mold or pouring mold is used for relatively smooth or simple products. There is no mold line to save labor and time. Just surround the product or model you want to copy with a rubber plate or glass plate, and pour the vacuumed silicone directly. Put it on the product, wait for the silicone to dry and form, take out the product, and the mold will be formed (Note: Infusion molds generally use softer silicone to make the mold, so that it is easier to demould and will not damage the product inside the silicone mold
