The temperature of the lead should be such that it is just enough to produce satisfactory castings in a heat-stabilized mold . 铅液的温度要正好适宜于在热稳定的模具中铸出合格铸件。
They can be divided into two classes, those which are castable and those which must be processed by extrusion or compression molding . 它们可分为两类：可浇铸的和必须由挤压或模压加工的。
In an effort to discover whether the foreign matter was tuberculous he then injected some of the mold into a rabbit . 为了要知道那异物是不是结核性的，他又把霉液在一个兔子身上注射了一些。
Different grades of crystal polystyrene molding pellets range from 150, 000 to 350, 000 weight average molecular weight . 不同牌号的结晶聚苯乙烯模塑粒料平均分子量范围从150，000-350，000。
He spoke hurriedly, as though trying to mold a substance which was warm and pliable, but which might soon cool . 他讲话很急促，好象他想要拿一种温暖柔韧的原料塑造什么东西，又怕原料冷得太快。
Maintaining the correct mold temperature becomes more important and may justify mold temperature control equipment . 保持模具有适当温度，越来越显得重要，因而配备模具的温度控制设备是完全合理的。
Mold spray life, with some of the formulas mentioned above, should be at least several hours with some touched up with the spray gun . 用上述配方配制的脱模剂，用喷枪喷涂，其有效期至少可达几小时。
The secret of preparing mold spray seems to lie in the thorough incorporation of the dilute silicate solution in the granules of cork . 制备脱模剂的关键似乎在于稀的硅酸钠溶液与软木粉的颗粒彻底混合。
