Why the silicone rubber mold will appear less reus...

Silicone rubber has a close relationship with our lives, and silicone can achieve the effects of environmental protection, non-toxic and food grade. Silicone rubber mold with the characteristic of high temperature resistance, corrosion resistance, tear resistance, and high simulation fine degree is a special mold used to make a variety of crafts, gifts, stationery, and sculpture, figure copying, architectural decoration industry and so on. This purpose we make silicone rubber mold is for mass copying and production of products. Generally, the reduplication of manual mold silicone rubber is 2-30 times; while, the mould making silicone rubber has higher duplication times, for example, the reuse times for gypsum/plaster products can reach 800-1000. In actual use, it often appears the situation that the silicone rubber mold will appear less reuse times. What causes this phenomenon of less reuse times? Today we come together to discuss the reasons.   The first reason for appearing less reuse times may be that the silicone rubber mold has not been vulcanized completely. If the silicone rubber mold has been insufficiently aged, it will give birth to these problems of deformation, poor quality and less reuse times for silicone rubber mold. So, you can start filling resin after the silicone rubber has vulcanized completely. Generally the time of curing for silicone rubber is one day at room temperature 25 ℃ and can also be accelerated by higher temperature reaching 50 ℃.     Secondly, the factor for less reuse times should be that the silicone rubber mold is used too frequently. Please Imagine that if every day you wear the same pair of shoes for a long time, this pair of shoes is very easy rotten. However, if your shoes are worn exchanging, it will have a longer duration of use. As another example, a person is going to get more energy and work well if properly rest and relaxation rather than continued work. In the same way, you should also let the silicone rubber mold to rest properly if possible to increase the number of mold making cycles. In other words, the durability of the silicone rubber mold will be improved if it is not used too frequently and is allowed to stand unused.   Thirdly, less reuse times can be due to the reason of improperly resin used with silicone rubber which will produce great heat of inadequately mixed for resin or adding too much catalyst. For this situation, you should eliminate this reason related to resin, such as switch to the optimal resin and silicone rubber to avoid the phenomena of less reuse times.   Of course, the maintenance for silicone rubber mold is also very important, and it should be stored together with the outer mold to prevent the silicone rubber mold from deformation and be cleaned after use. How to clean the silicone rubber mold? We usually adopt the way of sandblasting for cleaning the silicone rubber mold. First of all, you need to choose more appropriate washing sand mold according to the shape of the silicone rubber mold, and then put the washing sand mold and silicone rubber mold successively into the sand blasting machine. Next the mold cavity is gradually treated by means of sandblasting by order of the cavity.   Shenzhen Hong Ye Jie Technology Co., Ltd. is recognized as the global leading in the manufacturer of high quality silicone rubber products in an unsurpassed variety of RTV-2 silicone rubber, HTV silicone rubber, LSR, etc. We supply the most suitable & superior silicone rubber raw materials, but a reasonable price.
