Without opening mould, it can provide accurate buffer, high speed gap filling and high strength of supporting and positioning for different volume, switch and weight products.
无需开模，即可为不同体积、开关和重量的产品，提供精确的缓冲、高速空隙填充或者高强度的支撑定位。

However, the opacity of the metal mould and the high metal pressure during casting make the mould filling process very hard to be directly and visually evaluated.
然而，由于金属模具的不透明性和熔融金属的高压使得很难对充型过程做出视觉化评估。

The results showed that the content offilling was better to be 10% and the water soluble core-mould material had high strength, good glassy surface, good water-solubility, and so on.
