Gypsum crafts mold silicone

Resin crafts, gypsum crafts, unsaturated resin crafts, poly, crystal, candle crafts, large sculptures, cultural relic reproductions, architectural decoration relief furniture, plastic toys, gifts and stationery, imitation marble, human statues, imitation copper crafts, cultural relic production, models Mold manufacturing in many industries such as facilities and simulated landscapes. Note: It is indispensable for many industries to quickly replicate products.
Gypsum mold glue, resin crafts replica mold special mold silicone mold silicone features:
It has the characteristics of no deformation, high temperature resistance, acid and alkali resistance, and no expansion.
, good shrinkage rate, multiple molding times, and the mold silicone shrinkage rate is two thousandths.
Good tensile strength, elasticity, and tearability not only make your products beautiful, but also prevent the products you make from deformation. There is no problem with high temperature resistance, and the mold silicone is still not brittle at minus - degrees. It's very soft and the simulation effect is very good.
Gypsum mold glue, silicone gypsum, special mold for resin crafts replicas, silicone molds special for resin crafts replicas Operation:
There are three ways to open silicone molds: mold encapsulation (pouring mold), rinsing mold (sheet mold) ). Mold silica gel is a flowing white liquid, divided into two groups: group is silica gel, B is curing agent, for example, gram of silica gel is added to the curing agent and stirred evenly, and the following operations can be performed:
Mold opening methods include mold wrapping and brush molding (Slice mold, three-dimensional mold, flat mold), infusion mold
Brush mold (slice mold): Generally, three layers of brushing are used according to the mold requirements. The first layer of brushing is vacuumed on the mold type and brushed in place. The second layer is covered with gauze, and the third layer is coated with silicone to solidify and form.
The details are as follows:
First apply a layer of release agent or barrier agent on the product or model to be copied, and then take a certain amount of silica gel and curing agent (it is best to use an electronic scale to weigh it) amount), stir evenly, and evacuate. Do not evacuate for too long. Apply the silicone on the product (note: it must be applied evenly). After waiting for 3 minutes, the colloid will undergo a glue reaction. Then apply the second layer of silicone evenly. , at this time, a layer of gauze or fiberglass weft cloth is pasted on the surface to increase strength, and then a third layer of silica gel is applied. After the silica gel is dry, the outer mold can be made. The outer mold can use materials such as gypsum or resin.
Note: After applying a layer of silica gel, it is best to wait for the silica gel to cross-link and then apply a layer of silica gel instead of immediately pasting gauze or fiberglass cloth. The reason is: generally the coating is relatively thin, especially The fiberglass cloth is relatively hard and can easily make the inner layer of the mold smoother, thus affecting the effect of replicating the product.
How to operate the overmolding (pouring mold):
For relatively smooth or simple products, surround them with rubber plates or glass plates, take a certain amount of silica gel and curing agent, mix them evenly, and vacuum them Pour the silica gel directly onto the product. After the silica gel is dried and formed, take out the product and the mold will be formed (note: the molding generally uses softer silica gel to make the mold, which makes it easier to demould and will not damage the parts inside the silicone mold. product).
How to make the outer mold:
The generally used method and material is to surround the mold with plastic boards or wooden boards. Once the mold cabinet is filled with gypsum, the other is to use resin. The method of painting is to apply a layer of resin and then paste a layer of fiberglass cloth. After painting and pasting, repeat two or three layers.
Note: When making a sheet mold, you must make an outer mold, because the mold made from a sheet mold is relatively easy to deform, so an outer mold should be used to prevent the mold from deforming.
