How to make a silicone mold to do the prototyping for plastic parts
Typical Datasheet :
Item No | Color | Hardness (A°) | Viscosity (CS) | Tensile-strength( kgf /cm2 ) | Tear-strength (kgf /cm2 ) | Elongation-break(%) | Mixing Ratio of silicone and catalyst | Application(most for resin, gypsum and cement product to make moulds) |
E635 | Translucent | 35±2 | 8000±2000 | ≥60 | ≥13 | ≥400 | 1:1 | Most suitable for medium sized product |
Operation
1. Pls clear the model and tool totally before operation to prevent cure inhibition.
2.Weigh the two part correctly by electronic weight in two separate container .
3. Mixing the two part in 1:1/10:1 and stir part A and part B evenly in 2-3 minutes .
4.And get the mixture for vacuum-pumping for de-air the bubble in around 2-3
minutes . (If there is no vacuum machine, pls pour the mixture carefully and slowly
down the side of the mold frame so that less bubbles caused)
5. Enclose the product (the original model) with four plastic plates or wooden plates.
6. Clean your products and brush a layer of release agent(detergent or soap water) on
your product.
7. Pour the vacuumed mixture into the model frame from the side of the mold frame .
8. After cured, the original model is carefully extracted from the silicone mold using a razor knife.
9. The mold is cut to a point where the model can be extracted.
10. The mold is pried open and the prototype is removed.
11. The silicone mold captured perfect detail from the original model and is ready for casting.
12. Plastic is mixed and injected into the mold.
13. After a few minutes the prototype casting is removed from the mold, an exact copy of the original.
Advantages:
Flexible, high and low temperature resistance, resistance to ultraviolet radiation, environmental protection, water repellent, good air permeability, good insulation, shrinking smaller
Points of attention:
1,Prone to poisoning, can not mix with condensation, ionic compounds containing N, S-, P, organic matter and of Sn, As, Hg, Ph., easy molding plastic poisoning, resulting in the phenomenon of not curing.
2,Comparing with Condensation cure silicone, Addition cure silicone's adhesive properties to be worse.
3,Addition cure silicone affect by temperature greatly when cured under room temperature.
4,Addition cure silicone is easy to poisoning, please clean the tools which are used for condensation silicone rubber, so that it can avoid poisoning.
It’s fobidden to add the pigment or powder to addition cure silicone rubber arbitrarily,it’s easy to make the catalyst to be poisoning.
5,Addition cure silicone rubebr has two-component, the component A and component B, please pay attention to clean the component A containers before using for the component B, and vice versa
6,In order to avoid the hardness change, we should mix the component A and component B according to its mixing ratio strictly, no atter it’s 1 : 1 or 10 : 1.
