虽然当今制芯生产中90％以上都用树脂粘结剂,但是冷硬工艺已有了越来越大的增长趋势,其中尤以冷芯盒法为最。但是使用这类物料出现了工作条件与环境上的一些问题,就是说工厂监督员要制定更严格的条例并要符合洁净空气准则,其相应的结果是铸造厂要有高额资金投入来配备污染物捕集与处理设备。与此同时,对铸件正提出更准确的要求,自然包括芯子质量。越来越多的铸件要求伴有记录,因此质量保证可以越来越少地局限于仅做铸件检验,而必须愈益与生产工艺本身融为一体。在
Although more than 90% of core-making products use resin binders, the chill-hardening process has been growing more and more, especially in the cold box method. However, the use of such materials presents some problems with working conditions and the environment. In other words, factory supervisors have to make stricter regulations and comply with clean air standards. As a result, foundries need to invest a lot of money to provide pollution Material capture and handling equipment. At the same time, more precise requirements are being placed on castings, which naturally include the quality of the core. As more and more castings are required to be accompanied by records, quality assurance can be increasingly and less limited to casting only and must increasingly be integrated with the manufacturing process itself. in
