中温铸造蜡：AT868
JIUDING Casting Wax AT868 is formulated with a proven neutral no filler for liquid injection. The wax is light green in color. JIUDINGAT868 offers a wide liquid injection range with very little cavitation in the thick sections of the patterns.
“九鼎”牌AT868是一种含有中性非填料的淡绿色模型蜡，具有压蜡范围广，大型模蜡模没有气穴的高档模型蜡。
JIUDING AT868 reproduces excellent surface detail with good rigidity and dimensional stability and exhibits excellent flow characteristics. AT868 is suitable for an array of different parts ranging from small blades and vanes with or without fragile cores to large structural casting, aircraft castings, commercial hardware and thin walled parts.
它具有优良的表面光洁度，适中的硬度，尺寸稳定和非常好的流动性。它应用广泛，从小的含有陶瓷蕊的螺旋桨的叶片到一般性的超大铸件以及薄壳铸件都非常的适合。
This no filled wax can be used for both ferrous and non-ferrous castings because of minimum residue on burnout.
由于它是一种脱蜡后极低残留的非填充蜡，适合于一般的铁铸和合金铸造。
