Why does the silicone bracelet appear grease after being placed for a period of time?

Silicone bracelets are very popular among young people. in some public welfare activities, we can also see the figure of silicone bracelets, as well as the concert of different stars. the signing ceremony will grow longer. In short, silicone bracelet is a product that appears more frequently in our life. Silicone bracelets are gorgeous in color and very fashionable. however, silicone bracelets appear grease after being placed for a period of time. why is this?
First, the quality of silica gel raw materials will make it difficult to remove edges of silica gel products. poor quality silica gel raw materials have insufficient toughness and tear strength. it is definitely difficult to remove edges in the process of removing edges.
Second, the forming of products in the forming process is relatively thick, so the burrs are actually relatively thick, and the increase in thickness will definitely lead to the difficulty of edge removal.
Third, the problems in the molding die, if the mold self-disassembly design is unreasonable, the molding die is used too long, the molding die is worn seriously, and the quality of the molding die is not too high, these situations will make it difficult to disassemble the edges after production and molding. Mold opening technology, a good mold can ensure 90 % of the quality of a product. the mold opening level of the factory must be excellent. otherwise, the product quality will not pass, and any good research and development results will be wasted. the production capacity of the factory will keep up with that. if one day you develop and sell the product very well, but you can’t produce it, you have to wait a month for a single one, then mosquitoes will all sleep, and you must think twice in this respect.
Fourth, environmental factors of vulcanization, the vulcanization temperature should be appropriate, and the problem of too high and too low will lead to difficult edge removal. at the same time, the vulcanization time should also be well controlled. if the vulcanization time is too long, the product will become brittle, and if the vulcanization time is too short, the vulcanization link will be ineffective. therefore, the vulcanization link must be well controlled. When we are looking for suppliers, we must first find the manufacturer. we also need to pay attention to some details when finding the manufacturer. The quality of silicone gift produced by many manufacturers varies, and the silicone gifts produced by adding blue aurora vulcanizing machine to the mold will be of better quality. Many factories use the traditional vulcanizing machine to heat up the plate of vulcanized silica gel, which will produce some inferior products. if the employees are responsible, they will help you trim the burrs. if they are not responsible, they will make do with it.
Silicone bracelets appear grease after spinning for a period of time, mainly because silicone bracelets are not handled properly during the production process. Silicone bracelet is a very durable ornament, otherwise it will not enter our life and appear on the wrists of those elderly people. In short, in order to ensure the quality of silicone bracelets, we must choose the manufacturers of silicone bands.
