Plastic products silicone rubber production proces...

A wide variety of plastic products silicone rubber , silicone rubber crafts plastic vases for example , brush silicone rubber mold making plastic products , because of its simple structure mold species , so I chose a small viscosity , low hardness silicone rubber to brush mode , where you can choose leaves HY-628 silicon rubber mold . 　　Brush vase plastic mold making crafts began, we must first prepare the necessary tools to deal with the mold species polish formulated parting line , make the product easy to mold , mold parting line positioned at the highest point of the species , and the hub of the obvious binding site go. 　　The mold species fixed on the board, then vertically fixed on another board, close to the hardness of mold species heap softer sludge, can not have a gap , heap heal after a good wet clay by hand and cut off the excess sludge . Punch tenon , even in the sludge marked latch , latch about one centimeter from mold species , it is easy to mold . 　　Clean the surface of the mold species , such as Vaseline evenly coated with a release agent or detergent ( one can ) , the HY-628 silicon rubber mold and curing agent by mixing 2% -5 % fall in the proportion of Stir mold species , and then evacuated. 　　Evacuated generally not more than 10 minutes to read the meter , whichever pumping vacuum machine to -0.1mpa to stop , so you can do to prevent air bubbles out of the mold , otherwise the particle surface of the product will occur , affecting the quality of products , if there is no vacuum dryer , reducing the proportion of the curing agent added , the curing time extended silicone rubber , can release more bubbles . 　　Smoked vacuum brush mode after the start , the silicon rubber mold evenly coated on the species, the thickness of the first layer is less than 1mm, in order to cover the thin mold species can prevail ; After the start of the first layer is cured first floor brush silica , silica gel ratio of the second layer than the first layer, the curing agent is high, the curing time is about 5-8 minutes ; flow is not subject to silica , the silica paste layer of gauze , gauze is used to enhance the effect of the strength of the silica gel and tear degree , cured and then brush on a layer of silica gel . 　　Resin made outer mold , brush the first layer of silicone rubber molded resin , and then covered with a layer of glass fibers , the resin layer painted on , depending on the size of the mold species added 3-5 layers of glass fiber web . 　　After curing the resin outer mold , clean the sludge and used scissors to trim the edges of the silicone rubber mold , silica coated with Vaseline , silicone rubber will not stick . Then repeat the above steps to create the other half of the silicon rubber mold . 　　Subject to the entire mold after curing , the silicone rubber molds, resin outer mold repair flat. Generally 24 hours after the silicon rubber mold can be put into production use. 　　Datas are from Shenzhen Hong Ye Jie Technology Co., Ltd., if you want forward, please indicate it.
