Detailed Product Description
Silicon rubber for mold making applications
Silicon rubber for molding making is mainly applicable to manual mold design, PVC plastic molds, cement product molds, melting point alloy molds, alloy toy craftworks, plastic toy craftworks, gifts and stationery, large statues, duplication of cultural relics, shoe sole mold fabrication, pad printing positioning, shock resistance for electronic equipments, etc.
Silicon rubber for mold making features
Silicon rubber for mold making is white or red flowing liquid with general hardness of 22-50A°after curing. Requirements for the silicone rubber: low shrinkage, no deformation of the mould, good elasticity, the more moulds duplicated the better, etc.
Silicon rubber for for mold making operations
518# manual mold silicon rubber is flowing liquid with consistant quality in whatever color. It consists of two components, wherein component A is silicone rubber, and component B is curing agent or vulcanizing agent. Firstly process and prepare the model mold or the product to be duplicated, take certain amount of the silicone rubber, add 2-3% solidifying agent, and mix evenly for use. One mold pair can be solidified and formed in 2-3 hours. The formed mold can be used repeatedly without deformation and water shrinkage and with high temperature resistance, thereby providing fast duplication of the product with a product shrinkage 2. The 518 manual mold silicon is mainly applicable to manual molds and small number of product duplication.
Silicone Rubber mold making Standard Datasheet:
Model | Appearance | Viscosity (cs) | Hardness (Ao) | Tensile Strength (kgf/c) | Tear Strength (kgf/cm) | Shrinkage (%) | Elongation (%) | Mixing Ratio(%) | Operating Time(H) | Curing Time(H) |
518 | White | 12000~15000 | 22~30 | ≥7 | ≥3 | ≤0.3 | ≥200 | 2~3 | 0.5 | 2~4 |
What should we do when the air bubbles appeared in the process of mold making ?
To handle this situation depends on different cases. Under the condition of an available vacuum pumping machine, mix the silicone rubber and curing agent evenly and then take it to vacuum chamber to deair. If without a vacuum pumping machine, reduce the amount of the curing agent properly. For example, change the mixing ratio of the silicone rubber and the curing agent from former 4% to 1%-2%. In this way, the pre-crosslinking time of silicone rubber will slow down, so, the air in the mold will be eliminated gradually to reduce the air bubbles.
