It should be moldable and if it's not, just add a bit more water.

这应该是可塑形的，如果不行，那就再多加一点水。

Not to mention synthetic moldable polymers.

更不用说合成的可模塑聚合物了。

Many metals, for example, are almost infinitely moldable under the right conditions.

例如，许多金属在合适的条件下几乎可以无限成型。

Meanwhile, rocks aren't moldable at all, their lack of flexibility causes them to shatter or crumble under sufficient force.

同时，岩石根本不可塑，它们缺乏柔韧性会导致它们在足够的力下破碎或碎裂。
