The operation of tire mold silicone

HY series molding silicone is generally named two-components silicone rubber,Part A and part B.It features an exceptional fluidity and good operability.The mixing ratio is 1:1 (10:1),mainly be suitable for making molds application.Do you know the silicone for tire mold? Here I will tell you the operation of it.   　　Operation instruction of tire mold silicone: 　　1.please clear the model and tool totally before operation to prevent cure inhibition. 　　2.Weigh the two part correctly by electronic weight in two separate container . 　　3.Mixing the two part in 1:1/10:1 and stir part A and part B evenly in 2-3 minutes . 　　4.And get the mixture for vacuum-pumping for de-air the bubble in around 2-3 minutes.(If there is no vacuum machine, please pour the mixture carefully and slowly down the side of the mold frame so that less bubbles caused) 　　5.Enclose the product (the original model) with four plastic plates or wooden plates. 　　6.Clean your products and brush a layer of release agent(detergent or soap water) on your product. 　　7.Pour the vacuumed mixture into the model frame from the side of the mold frame .   　　Notice: 　　As our tire mold silicone is RTV-2 silicone rubber, which is very easy to cause cure inhibition , so please do remember thoroughly clean the model and tool before operation.Besides,please avoid the liquid tire mold silicone contact or mix with the following material,otherwise the silicone won’t be cured : 　　1.Liquid condensation silicone (condensation silicone not completely cured or organic tin compounds) 　　2.Sulphur,sulfide and sulfur rubber materials. 　　3.Amine compounds as well as contains the amine materials. 　　4.Pewter solder flux.           If you want to learn more about silicone rubber,please feel free to contact us:86-0755-89311348.
