In the production process, there are sometimes some small problems that often affect the quality and process output of silicone products. For example, when the product is demolded, it is not easy to demould, the self-cutting burr is too large and the product is torn, and some molds have too many cavities and are relatively dense. Nozzle screen printing can produce better and faster, so it is necessary to ensure that the entire die surface cannot fall off when the die is ejected. At this time, these details need to be solved during production. How to deal with this phenomenon?
Generally, relatively small things need to be demolded in this way, such as sealing rings, bracelets, and some daily miscellaneous items. One is to make the trimming faster, and the other is to make it more convenient for silk screen printing. The processing method is as follows:
1. The spraying of demoulding water can ensure rapid demoulding, so after every few molds, spray a little demoulding water to ensure that the surface of the mold does not stick to the mold.
2. The control of the ejection time is stable. Early ejection will cause the product to become soft and seriously stick to the mold. If the ejection time is too long, it will cause the product to be too brittle and easily break from the middle. the best method.
3. The amount of sizing material affects the thickness and quality of the product. It also needs to be controlled at a certain weight. Too light will cause the product to be short of material and corners.
4. The temperature and pressure are controlled within the range of the finished product. The high and low temperature will also affect the difficulty of demolding and tearing of the product. If the pressure is too high, it will also affect the connection of the whole mold product.
For silicone product manufacturers, the factors that affect the product are not only the above reasons, but also many external factors, such as mold, environment, raw materials, artificial, etc., for silicone products that are not easy to demould can also be caused by these reasons. Looking for problems, but most of this phenomenon occurs in molds and machines,
