Note: the time for vacuum-pumping should be less than 3a5 minutes , otherwise, once the silicone rubber has cross-link reaction during vacuum pumping process, it will not be operated. Step three: brushing cast & perfusion molding operation Shelf life for silicon rubber for mold making 10~12months, when stored in a dry & cool place under the room temperature 25. Faq silicone rubber for mold making: Why is the silicone mold oily? The molding silicone rubber itself doesn't contain any oil, so it won't be oily. If the mold is oily, it may because you add compound silicone oil which is the compound of silicone oil and white oil. But the white oil is not silicone oil but a kind of petrochemicals.

The pad printing silicon rubber usages: The silicon rubber is mainly use for printing irregular patterns of plastic toys, electroplating toys, trade makers .Silicon pad printing is a carrier which transfer printing the patterns on the steel plate onto the toys products surface. Pad printing silicon rubber features: Pad printing silicon 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 are available and our catalyst is free charged. Pad printing silicon rubber operation instructions: Pad printing silicon rubber is two-component silicone, part a is the liquid silicon 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 silicon 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 silicon rubber: The reasons why the silicon 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.

Frequently asked questions for Silicon rubber for manual mold 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. 25KG,200KG/DRUM PACKING Delivery Lead Time : within 3 days after payment confirmed in bank

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.

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.

The machine is applicable for plasticating and mixing rubber and plastics. Structural features: The internal mixers of this adopt elliptical tangential rotors. The wings and working surfaces of the rotors, the internal surfaces of the mixing chamber, and the working surfaces of the pressing ram device and the discharging device are all coated on with wearable hard alloy by built-up welding method, which are durable and corrosion proof and have a long service life. The rotors, the mixing chamber and the discharging door are all structured with circulating channels to realize the circulation of heat transmission mediums. According to different processing requirements, the mixing materials may be heated by hot steam or cooled by cold water. The mixing chamber is a combined configuration, which is convenient for assembling, disassembling and maintaining. The drop-door discharge device is driven by two reciprocating oil cylinder which directly pull the locking plate to lock the discharge door. The device provides fast discharging and reliable airproof. The rotors are supported by rolling bearings, which are easy to maitain and have a long service life. The transmission system adopts a hard facing gear reducer, which has a compacted structure with higher transmission effciency, lower noise and longer service life. The pressing ram device may be driven by pneumatic cylinder or oil cylinder to press onto the mixing materials to force them equally mixed so as to increase productive effciency. Mated with the electric controller, the pressing ram device can automatically add pressure, release pressure or just keep floating. Both manual and automatic modes are arranged to operate plc electric system. It is easy to exchange the modes and reliable to operate the controller.
