Molding silicon rubber is a kind elastic silicon rubber mold which features with resistance to deformation, high-temperature, acid-alkali and expansion as well as high reproduction times, good tensile strength, tear strength and elongation. 1 good flowability, light viscosity, easy operation 2 low shrinkage 3 good tension and tear strength 4 no deformation 5 high temperature resistance, acid & alkali resistance and aging resistance Silicone rubber for mold making datasheets Model: silicone rubber for mold making Appearance: white Viscosity (cs): 17000-20000 Hardness (A): 24-26 Tensile strength(kgf/cm2 Curing time (hours): 2-4 Model: silicone rubber for mold making AppearanceWhite Viscosity (cs)12000~15000 Hardness (Ao)50~80 Tensile Strength (kgf/c?)=7 Tear Strength (kgf/cm)=3 Shrinkage (%)=0.3 Elongation (%)=200 Mixing ratio (%)2~3 Operating Time(H)0.5 Curing Time(H)2~4 Model: silicone rubber for mold making Appearance: white Viscosity (cs): 19000-25000 Hardness (A): 28-32 Tensile strength(kgf/cm2 ) Tear strength (kgf /cm): Elongation break(%): Retractility (%): Curing agent mixed rate (%):2-3 Operate time (min): 30 Curing time (hours): 2-4 Model: silicone rubber for mold making Appearance: white Viscosity (cs): 30000-33000 Hardness (A): 30-32 Tensile strength(kgf/cm2 ) Tear strength (kgf /cm): Elongation break(%): Retractility (%): Curing agent mixed rate (%):2-3 Operate time (min): 30 Curing time (hours): 2-4 Silicone rubber for mold making operations If the customer wants to make large products and large size molds, the mold should be made of silicon rubber with high hardness. On the contrary, if the mold with fine and precision patterns, it should be made of silicon with low hardness. The amount of the curing agent depends on the actual requirements of the customer. If molds requiring fast drying and demolding, more curing agent is needed; contrarily, if molds requiring slower drying and demolding, less curing agent is needed. (Note: our company does not recommend you to add silicone oil. If a special soft silicone mold or fine detailed and complex patterns products are required, 5%-10% silicone oil can be added to soften the mold for easy demold.) Frequently asked questions of Silicone rubber for mold making Why does the silicone rubber mold have few molding times? The silicone rubber mold has few molding times is due to follwoing reasons: adding too much silicone oil which will destroy the molecular of silicone rubber; making the mold for small and fine detailed products with higher hardness silicone rubber which is easy to break; making the mold for large products with soft silicone rubber which will reduce the tensile and tear strength of the mold, and the mold will have deformation. Thus, we should take the proper silicone rubber to make the mold for suitable products.

Manual mold silicone rubber applications Manual mold silicone rubber 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. Manual mold silicone rubber features description Manual mold silicon rubber features with the resistance to deformation, good tensile strength as well as low shrinkage, and time of reproduction determined on the basis of customers. 1 Good elasticity 2 Non-deformation 3 Heat resistance 4 Low shrinkage Model Codes of Manual Mold Silicone Rubber HY-528 is applicable to make molds of smaller products and the production will be 2-3 pieces. HY-540 compared to other two types, for its moderate hardness and better quality & performance, its production will be 20-30 pieces. HY-57 is applicable to large size products duplications and Electronic equipment antivibration. Manual mold silicone rubber operations Firstly process and prepare the model mold or the product to be duplicated, take certain amount of the silicon rubber, add 2-3% solid curing agent, and mix evenly and they are ready for use. One pair of mold can be solidified and formed in 2-3 hours. (Note: our company does not recommend you to add silicon oil. If a special soft silicon mold or fine detailed and complex patterns products are required, 5%-10% silicon oil can be added to soften the mold for easy demolding.) Frequently asked questions for manual mold Silicon rubber 1. 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 silicon 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 silicon rubber and the curing agent from former 4% to 1%-2%. In this way, the pre-crosslinking time of silicon rubber will slow down, so the air in the mold will be eliminated gradually to reduce the air bubbles. 2. What should we do when silicone rubber mold didn't cure evenly? The reasons why the phenomenon arises are as follows: incorrect mixing proportion of the silicone rubber and the curing agent due to unqualified weighing; uneven mixing of the silicone rubber and the curing agent, which may cause material wasting , and we should avoid it . 3.What should we do when the silicone rubber stick with the mold? It arises because we didn't handle the model mold (product mold) properly. Before mold making, the model mold has to be sanded and polished, and cleaned carefully concerning the master mold with a coarse surface or to make complex molds. and then brushing a layer of release agent evenly. General release agents include Vaseline, detergent, liquid paraffin, etc. The release agents can be selected according to the different textures of various model molds. 4.What should we do if a silicone rubber mold product deforms? The solution depends on the size of the product. In principle, the size of the product should be in direct proportion to the hardness of the silicone rubber. Regarding small or very fine detailed products, soft silicone with hardness of 10-20 shore A is required for easier demould without damaging the lines of the fine products. Regarding large products, such as products with size above 50 cm, silicone rubber with hardness of 40-50 shore A is required for non-deformation. Regarding large but fine products, silicone rubber with hardness of about 30 shore A can be used for mold making (the method is to brush a layer silicone rubber and then paste a layer of glass fiber cloth and brush another silicone rubber), the outer mold can be made of gypsum, fiberglass reinforced plastics (unsaturated resin plus glass fiber cloth) for preventing the products from deforming.

This vertical rubber cutter is mainly used to cut the natural rubber, synthetic rubber, and other plastics materials, especially it is suitable to be installed near the rubber mixer to cut small piece of rubber. This vertical rubber cutter mainly consists of rubber knife, frame, cylinder, base, auxiliary table, hydraulic system, and electric system. The nylon plate is installed on the base under the cutting knife for protecting the edge of the cutting knife. When cutting the raw rubber, put the raw rubber under the rubber knife, then press the start button, the knife can cut the rubber. Two limit switches are installed on the frame to control the reversal valve to change the movement direction of the rubber knife, at the same time it protects the cover of the cylinder.
