硅橡胶成型工艺中拔胶现象浅析

Analysis of the Pull-out Phenomenon in the Molding Process of Silicone Rubber

介绍了硅橡胶成型工艺中的拔胶现象,浅析了工艺条件对硅橡胶制品的影响,调节固化温度和固化时间可以改变硅橡胶制品的硬度,而凸出物的硬度是影响拔胶与否的一个要素,同时凸出物的形状也对拔胶产生影响,通过降低固化温度和增加固化时间,改变凸出物的硬度,同时改善硅橡胶制品在拔胶处的外观,在硅橡胶制品的质量能够保证的前提下,尽量消除拔胶现象,继而可以简化操作,提高效率。

This article introduced the phenomenon of pull-out in the silicone rubber molding process,and analyzed the influence of process conditions on silicone rubber products.By adjusting the curing temperature and curing time,the hardness of the silicone rubber products can be changed,and the hardness of the protrusions affects the pulling out.At the same time,the shape of the protrusions also has an impact on the pullout.By reducing the curing temperature and increasing the curing time,the hardness of the protrusions can be changed,and the appearance of the silicone rubber on the premise that the quality of the product can be guaranteed,the phenomenon of pulling out the glue should be eliminated as much as possible,and then the operation can be simplified and the efficiency can be improved.
