水溶蜡：ATW07

Today a lot of Chinese foundries still use core of caramide to produce special structural casting, for example: valve, pipe and impeller, but the carbamide, its intensity is low, the process of products is handmade, efficiency is low, it is not fit for big casting and big batch products, water soluble core wax can meet these requirement.

Paste injection machines are often used for injecting soluble core wax. After the core is removed from its die, it is placed in the wax part die and then to inject wax around it. The pattern containing the soluble core is placed in the a batch of dilute hydrochloric acid or dilute citric acid to dissolve the soluble core wax. The wax pattern is rinsed in clean water to remove soluble core wax or acid and allowed to dry. We also produce soluble core wax that can be checked through fluorescence, in order to increase strength; our water soluble core waxes are available with added fiber.

今天中国许多工厂还在使用尿素芯来生产特殊结构的铸件，如管阀件，接头和叶轮，等复杂行腔的铸件，但尿素芯强度低，生产工艺采用手工操作，效率低，对要求高，尺寸稍大的逐渐或大批量的产品无法满足要求。

“九鼎”的水溶蜡芯，不仅表面光洁度高，强度大，而且溶蜡方便快捷，把包含水溶蜡芯的蜡模放入稀盐酸或柠檬酸的容器内溶解，水溶蜡芯溶解后，经过漂洗晾干后会得到复杂行腔的蜡模。目前，我们在一些水溶蜡里添加加强助剂，进一步提高水溶蜡芯的强度。
