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.

Silicone rubber for mold making features description Silicone rubber for mold making is white or red flowing liquid with general hardness of 22-50A¡ãafter curing. 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.

Pad printing silicone rubber applications Pad printing silicone rubber is mainly use for printing irregular patterns of plastic toys, electroplating toys, trade makers .Silicone pad printing is a carrier which transfer printing the patterns on the steel plate onto the toys products surface. Pad printing silicone rubber features description Pad printing silicone rubber with high print times and abrasion resistance, without any inpurities, with good printing effects, permanent and durable, we can provide all kinds of colors and our catalyst is free charged. 1 resistance to deformation, high-temperature 2 high printing times 3 good aging resistance 4 exceptional elasticity 5 great printing effect Pad Printing Silicon Rubbers Standard Datasheet ModelAppearance Viscosity (cps)Hardness (Shore A) Tensile-strength (kgf/cm2)Tear-strength (kgf/cm)Shrinkage (%)Elongation (%)Mixing Ratio (%)Operation Time (h)Demould Time (hrs) Pad printing operation silicone rubber instructions Pad printing silicone rubber is two-component silicone, part A is the liquid silicone rubber, part B is the catalyst. The usual mxing ratio for silicone rubber and catalyst is 100 : 2-3, eg. we take 100grams of liquid silicone rubber, then we add 2-3 grams catalyst, mix then evenly and pour it to your mold. Then after 2-4 hours, you will obtain a printing pad. Frequently asked question of pad printing silicone rubber The reasons why the silicone pad has a short service life are listed as follows: (1)The problem caused by inappropriate filtration of silicone rubber, and impurities in the packaging process due to the uncleanness of barrels and bags. (2)The short service life of the silicone pad has a close relationship with the adding amount of silicone oil. The more the silicone oil added, the softer the silicone pad will be. The silicone oil will destroy the molecule of the silicone rubber, thereby bringing about the non-durable and easy ageing of the silicone pad. (3)All the users should know the properties of pad printing silicone rubber. The service life of the silicone pad has close relationship with the size of the printed patterns. For example, if a big pattern to be printed, a big silicone pad is required; if a small pattern to be printed, a small silicone pad (the silicone pad has to be adjusted according to the size of the patterns, and the proportion between the size of the silicone pad and the pattern is 3:1.)
