前言波兰Warsaw工业大学在制芯新工艺基础上研制出生产铝合金铸件用的新系统并取得专利权。这种制芯新工艺不用普通的机械方法清除砂芯,而是把热或冷的铸件浸在水里,砂芯很快破碎,因而砂子容易从铸件里流出。芯砂

Preface Warsaw Polytechnic University of Poland has developed and patented a new system for the production of aluminum alloy castings based on the new core making process. Instead of removing the sand core by ordinary mechanical means, the new core-making process immerses the hot or cold castings in water and the sand core breaks down quickly, so the sand tends to flow out of the castings. Sand core
