- 摘要:
- 针对湿型砂铸造工艺在生产高质量的汽车零部件上存在铸件稳定性差、尺寸精度低的弊端，提出了随形金 属托模覆膜砂壳型铸造的工艺，该工艺不仅可满足生产高质量铸件的要求，还可降低成本、减少污染。同时，通过结合采 用该工艺成功生产出高质量、高成品率（96%~98%）的德国曼汽车发动机缸盖的案例，进一步验证了该工艺在汽车零部 件的制备领域上的潜在优势。In view of the disadvantages of the low stability and dimension accuracy of the green sand casting process in the production of high-quality automobile parts, a casting process of plastic sand shell with shaped metal support was proposed. The process can not only meet the requirements of producing high quality castings, but also reduce the cost and pollution. At the same time, through the combination of this process successfully produced high quality, high yield (96%~98%) of German MAN automobile engine head case. The potential advantages of this process in the field of auto parts preparation are further verified.
