The approach for producing flat backed objects for instance badges, pendants, wall plaques and various jewellery items is mostly the exact same. The silicone resin jewellery moulds can be produced by possibly pouring or brushing the silicone on to the initial piece. Pouring is most likely the simplest system for all products which has a flat again. The process is as follows:
Pick out an acceptable container
The very first thing we want to take into consideration for this method is how to have the poured silicone after we pour it above the initial product.
With more compact goods we are lucky to have a massive number of acceptable containers that may be conveniently acquired. Ice product containers, takeaway meals containers or perhaps butter containers are merely to call a few. We are seeking a container which happens to be about one-2cm larger than the design all throughout the sides. We’d like the container to also be 5cm taller when compared to the product.
In case your merchandise is incredibly smaller you might not even require a container. It is possible to fix the little product to a little board having a non hardening clay or glue if you prefer and Establish up a wall within the product with clay or perhaps lego bricks.
With larger sized goods instead of fixing the model to a board you may take care of it on to The bottom from the container you choose. It is necessary to fix the model securely to The bottom to ensure that it will not likely float to the best when silicone is poured in.
In this article We are going to go into depth the strategy which takes advantage of a food container.
Using a plastic food items container to be a mould dam
The first thing you’ll want to do would be to protected the lid tightly on to the container. Switch the container upside down and Slash The underside out of it.
Now secure the model to The bottom (which will be the lid) from the container with glue or clay.
The application of launch agent isn’t normally desired when making use of silicone since it sticks to only a few products. Glass is one item which silicone ซิลิโคน motiva has a tendency to stick with. It can be a smart idea to do a small check When you are Uncertain. If you find a launch agent is needed you can also make your individual with petroleum jelly dissolved in a solvent for instance white spirit. We use a ratio of 10% petroleum jelly. You may then spray or brush the solution onto the model and Permit it dry. The white spirit will evaporate leaving a high-quality even movie of petroleum jelly guiding to the model.
The silicone we use to pour around the product comes in two components and needs to be mixed collectively to get started on the curing course of action. The mixing ratios rely on the silicone you use and are available within the label of your respective silicone. We discover waxed disposable paper cups to generally be ideal as mixing containers and picket stirrers or paddle pop sticks for mixing.
Pour aspect A and component B right into a new container and mix extensively scraping the perimeters and the bottom from the cup to make sure suitable mixing. Make sure you Do not whip air into the combination as this could produce abnormal air bubbles. A folding motion is greatest.
Once it is combined pour the combination right into a new mixing container. This ensures that no unmixed product continues to be within the cup when pouring it on to the product.
If you can find places around the product which have quite fantastic detail or undercuts it is recommended to brush some silicone on to These areas prior to pouring. This can make certain that the silicone will flow onto Each individual and every surface and decrease the prospect of air bubbles on these large specific areas.
You can now begin pouring the silicone on to the model. Pour in a skinny stream from the higher issue around the model. This slim stream from a higher level will power any bubbles while in the combination to pop on just how down. Also start out pouring onto the lowest point from the mould container. It’s best to not pour right on to the design so purpose for the floor on the mould container. Go on pouring until finally you may have 1 cm of silicone earlier mentioned the highest point from the product.
Go away the silicone to established right away. It is possible to de-mould the product the next working day by getting rid of the lid through the container and urgent the silicone Carefully through the leading. It need to slide out The underside. The design should really simply come out from your silicone and go away a cavity Prepared for casting. Permit the silicone mould get rid of appropriately for yet another couple of days for for a longer time mould everyday living.
