Descripción del producto

silicone rubber are generally named:



Two-component room temperature vulcanization silicone rubber ,a kind of elastic silicone rubber mold which features with resistance to deformation.high-temperature,acid-alkali and expansion,It mainly applicable to make the silicone mould for cultural relic duplication ,architectural decoration,resin crafts ,lighting ornaments ,candles ,statues mold design,product exploitation etc.



Instruction for using  silicone rubber for mold making to make molds.



Step 1:Preparing mold.



Once you have your model to mould you need to build a box from wood/acrylic to contain the silicone and get a good covering over your model ,The size and shape of this container is totally depends on shape of the model ,remembering to leave plenty room surrounding the model so that you will have a strong wall thickness (at least *0mm)



Note:Small models can be cast in sourced containers like tins ,ice buckets ,cake tins,etc



Once you have constructed your box and clamped it together you need to seal the box with a 



Bead of clay around each corner to stop the silicone from leaking out.



Step 2:measuring and mixing silicone



Liquid silicone for mold making requires accurate weighing of components(A+B)to achieve a proper cure.It is important that you take your time and use an accurate set of scales .Dietary and postal scales are not accurate enough.The most common mistake that people make when they are modeling with silicone is that they dont mix the two components well enough and thus it does not cure properly .



Step3:pouring the mold



Once you have carefully mixed the silicone ,it is time to pour the mold and start at the lowest point .This way the silicone will push the air out .as it flows over the model instead of trapping it.



Step4:



After setting the mold aside until cured remove the clamps from your box and you are ready to remove original model from the mold .The easiest way to approach this is to work your way around the side of the model pressing away the silicone allowing the model to loosen and air get underneath it.



Your mold is now complete and you are ready to start pouring parts.
