Mold Making Silicone Rubber World……

When you copy a garden sculpture model, we often use copying silicone mold and curing agent according to a certain ratio to complete the operation, of which the technical parameters to select(hardness, viscosity, shrinkage, etc.)and copy silicone mold and the radio of curing agent case we have to choose the most suitable one to produce good sculpture models. Copying Silicone mold mainly used for toy and gift industry, craft gift industry, furniture decoration industry, figures copied, building decoration industry, resin handicraft industry, unsaturated resin crafts industry, the plastic toy industry and candle crafts industry, gifts industry, stationery industry, gypsum gifts industry, mold manufacturing industry, bolero craft, simulation plant and animal sculptures industry, Buddhist carvings crafts products and other industries copy and mold making. ①Copying silicone mold has a better operating properties. ②Copying silicone mold has better fluidity, low viscosity and is easy to opera

Adult sex products for the two-component addition cure silicone rubber, consists of two parts: A component is a silicone, B component is a curing agent; two components mix ratio of 1:1 ratio. After vulcanization becomes soft, resilient material of low hardness after curing, good tear resistance, good color sense, good texture and other characteristics. Can be made, such as the human body, insoles, shoulder pads, patch, anti-slip mats and other flexible silicone rubber products, but also for the simulation of human facial silicone molds, mainly for the human face, supplies, human organs, mimicking the body shape, the same type, changing shape, soft touch. Adult supplies silicone had a very strong smell, which is due to not using odorless curing agent in the production of secondary sulfur can remove this odor, the harm to the human body is very small and can be ignored, and this is inevitable scented products after all any vulcanized silicone products will smell over time. Friendly remin

1. Why silicone mold will be fewer turning models ? If the products do little more complex patterns come with a large hardness silicone mold, there will be a fewer turning molded phenomenon, because silicone excellent time will be very brittle and easily broken. Conversely, if you do build a product to do with a small hardness silicone mold, the result will also be unsatisfactory. Because silicone is too soft, it will reduce the tensile and tear strength, made out of the mold will be deformed, turning model number will be reduced. Mold itself good quality, silicone no good or bad, only suitable or unsuitable. We want to use for the product to make the hardness of the size of the silicone mold will not appear in this situation. 2. Why mold silicone mold phenomenon appears to burn ? Because unsaturated resin and resin products plus a peroxide curing agent after the case of the resin reaction will generate a lot of heat, usually resin curing time is 3 minutes, then three minutes after goi

  The amount of the curing agent depends on the actual requirements of customers. If molds require fast drying and demould, more curing agent is needed, and the mixing ratio shouldn’t be over 5％, the more curing agent, the faster the molding time. Or it will waste the silicone rubber. Contrarily, it is the silicone potting mold, less curing agent will be needed to lengthen the operation time. The mixing ratio of silicone and the catalyst shouldn’t below 1％, otherwise, it would need a longer curing time. With the mixing ratio less than 5%, it would have little influence on the hardness, tear strength, and tensile strength. Silicone and the catalyst: 1. Curing agent 1% added, the silicone can still be operated within 2.5 hours and can be demoulded after 6-8 hours. 2. Curing agent 2% added, the silicone can still be operated within 50 minutes to 1 hour and can be demoulded after 2-3 hours. 3. Curing agent 3% added, the silicone can still be operated within 28 - 30 minutes and can be demou

Users sometimes use liquid silicone curing problems encountered, now our summarizes five kinds of the cause of the rtv-2 liquid silicone not curing and their solutions, we hope to help. 1. A curing agent or too little of the curing agent will affect the cured silicone. According to the provisions of the curing agent is added, and should see clear instruction is the proportions of the volume or weight. 2. Different types of curing agents can’t mix, add molding glue exposure to tin ingredients in the condensation silicone will not respond. With the corresponding models of the curing agent. Operating tools are classified, do not mix. If you are operating plus molding silicone, do not come into contact with condensation products. 3. Silicone and curing agent do not stir evenly. Silicone and curing agent operation to fully stir well. 4. Incomplete cure (not dry) in the contact surface occurs only master, the other parts of the intact curing. Marked on the surface of the master mold with a t

Different products may need different hardness of silicone. Common silicone’s hardness is suitable for most products, but there are some industries that need high hardness silicone. So what is the maximum hardness of the silicone? When the hardness is over 50 shore A, it can be called high hardness silicone. When the hardness is more than 50 shore A, the tear strength of silicone would be weakened, the silicone products would become crisp and easy to be broken off. Most high hardness silicone is used for leather printing, plant gum, rubber roll, trademark, nursing bottle and so on. The maximum hardness of silicone is 65 shore A, for higher hardness, you need to add a hardening agent yourself.

 The liquid silicone was divided into two types: addition silicone and condensation silicone. Addition silicone is used for manufacturing insoles, shoulder pads, plackets, padding and other flexible silicone products. Condensation silicone is used for making soap, candles, etc. Usually less than 10 shore A hardness is called low hardness soft silicone, it is soft and easy to de-mold, and for addition silicone, the lowest hardness is 00-30 shore A, for condensation silicone is about 5 shore A.

The quality of RTV liquid silicone rubber raw materials will affect the quality of silicone molds and their applications. The determinants of the quality of silicone are viscosity, hardness, tear strength and tensile strength. Let me share with you some tips for judging the quality of liquid silicone.  Viscosity: The liquidity of silicone rubber is determined by viscosity. Let liquid silicone rubber vertical natural flow down when testing it. The faster the flow, the better the fluidity of the silicone. Please note, viscosity is proportional to tear strength. Do not use low viscosity silicone to pursue liquidity, which will lead to silicone molds with low tear strength to reduce reproduction. Some factories add much silicone oil to increase liquidity, which also deterioration in tear strength. Hardness: Hardness is one of the important technical indicators that reflect silicone material rigidity. If the hardness of the silicone is below shore A 10, the silicone products have low tear s

When we use liquid silicone rubber to make a silicone mold,we may find that the silicone rubber have not cured or not cured completely after 48 hours.What are the causes of this? In the experience of  liquid silicone rubber factory,there are 5 possible reasons that generate the silicone not cured or cured not completely. Reason 1: Too much or too much curing agent can be influence silicone to cure. Resolution:Add curing agent due to prescribed ratio,and please note instruction that the mixing ratio is by volume or by weight. Reason 2 : Different types of curing agents can not be mixed, addition silicone will not cure if it contact the tin composition in condensation silicone. Resolution:Use the corresponding types of curing agent and the tools are not mixed. Never contact the condensation silicone product when you are using the addition silicone rubber. Reason 3: Silicone and curing agent are uneven mixing. Resolution:Silicone and curing agent should stir evenly,especial in the bottom
