Casting silicone rubber factory

Description of casting silicone rubber: Casting silicone rubber with two part, part A and part B, both are liquid foam. Mix ratio is 1:1 or 10:1.   Application of casting silicone rubber: Casting silicone rubber is used for making molds of Precision Mold Casting, automobile model casting, auto parts and similar products.   Characteristics of casting silicone rubber: ＊Outstanding bubble releasing ＊Non-deformation ＊Low shrinkage ＊Aging resistance ,high temperature resistance (200℃) ＊Environmentally, food-grade ＊An exceptional fluidity and good operability, easy to demold ＊High tensile and tear strength ＊Good flexibility   Operation instructions of casting silicone rubber: Step 1: prepare the original molds Prepare an perfect original mold and clean it totally before operation . ＊Notes:Make sure your original molds and operation tool cleaned up totally to avoid uncure problem .   Step 2: Take 100 G part A and 100 G part B (Or 100 G part A and 10 G part B) and mix them evenly. ＊Notes: Addition cure mold making silicon rubber is two part flowing liquid , Pls follow the step strictly: 1.Weigh the two part exactly by electronic weight.. If any part not in exactly weight , it may cause changing of hardness , or even cause uncure problem. 2.Mix part A and part B evenly. Otherwise the silicon rubber will be partly solidified and this will give birth to difficulties in your final operation. What’s more, the finished molds will meet a short life. All of these will cause a waste of silicon rubber.   Step 3: Vacuum pumping Without exception, this step takes less than 10 minutes. Otherwise, it will cause cross linking reaction, and no more further steps will be available.   Step 4: Pouring casting or Brush operation ＊Notes:1. For simple pattern products we suggest use pouring operation way , which will be very easy to operate and demould. Pourable silicone require light viscosity which will be easy to flow smoothly and easy to de-air . 2.For delicate pattern products we suggest use brushing operation way , which can copy the pattern exactly . Brushable silicone require high viscosity which won’t be easy to flow away and easy to brush . 3. We suggest to set the silicone mold for another 12 hours after demould before put into large production .   HONG YE JIE LIQUID SILICONE Packaging & Shipping: Sample packaging: 1kg Cargo packaging: metal drum and plastic drum: 20kg, 25kg and 200kg Shippping: Transport as non-dangerous Article
