用汽化模生产铸件主要包括两个阶段。第一阶段是生产聚苯乙烯汽化模,要求汽化模密度稳定、不含水分。其密度要求为15～30g/L,最大误差为±1g/L。普通的、用于工业包装的成型机不能准确控制不同厚度工件的加热温度。FATA公司使用模型导引装置,以保证在不同热度分布的情况下能获得精确的尺寸。该公司成型机的生产节拍,1件/min(包括自动取件的停机时间)。采用粘法或热焊法组装汽化模。热焊法操作迅速,但模样尺寸会缩小(mm以下)。因而宜使
Production of castings with vaporization mold mainly consists of two stages. The first stage is the production of polystyrene vaporization mold, the vaporization of the mold requires stable density, moisture-free. The density of 15 ~ 30g / L, the maximum error of ± 1g / L. Ordinary, for the industrial packaging machine can not accurately control the heating temperature of different thickness of the workpiece. FATA uses model guidance to ensure accurate dimensions for different heat distributions. The company’s molding machine production beats, 1 / min (including automatic pickup of the downtime). The use of sticky or hot welding assembly vaporization mode. Hot welding method operates rapidly, but the size of the sample will be reduced (mm below). Therefore should make
