How to inject liquid silica gel into the mold, first of all to distinguish what type of mold belongs to, different types of mold operation skills are not the same.

  Liquid silica gel is divided into many kinds, and the process of making silica gel products is divided into two kinds, one is machine production, the other is manual operation.The liquid silica gel used in these two processes is different;Machine production molding is generally mass production of silica gel products, such as our common baby pacifiers and kitchenware, this type of machine production to achieve mass production, and the production of the same product specifications.This type of silica gel is usually injection molding silica gel, which belongs to the liquid silica gel produced by the meteorological method.Reach food-grade contact certification and even achieve biocompatibility certification, which is mainly used for medical products.The general process of machine injection molding is that the two pipes AB are connected to the silica gel of the two components AB, and the two components AB of the same weight are absorbed by the pressure of the machine. The two components AB are mixed and stirred in the pipeline and vacuumized, and finally injected into the steel film. After high temperature treatment, the silica gel is quickly changed from liquid to solid. Under normal circumstances, the temperature of 120 degrees about a few seconds to more than ten seconds can be completely cured and removed film, so as to achieve rapid factory, because it is machine molding so the size of the injection molding product specifications can not be seen by the naked eye.And the other a kind of artificial molding process, the most use of liquid silicone as precipitated silica gel, and this kind of product is for single piece or batch products use less, the overall cost will be lower, manual operation of silica gel does not need to open steel film aluminum film, a large, less steel film aluminum film down thousands of your ten range, and the products of the manual operation you just need to plain die, For example, our common plaster mold, or resin mold, FRP mold or blister mold can be.These costs are relatively low, a few dollars less, more than a few hundred pieces, secondly, the standard requirements of the product are not particularly high, because the manually operated silica gel products have a certain deviation, there is no way to achieve the standardization of the silica gel products produced by the machine.

  The two molding processes mentioned above have their own advantages. As for which one is suitable for you, you can consult professionals. For example, Xinjia silicone is a factory specializing in the production of liquid silica gel.The above two kinds of process, the molding machine that a less liquid silicone injection mold problems, manual operation is much more than that of the about and at the time of production mold, if there is a reserved glue, glue and glue mouth size whether reasonable, if the relatively small caliber of silicone interoperability with liquidity requirements is relatively high, You can do it with something like a funnel that makes it a little bit easier.
