Molded case circuit breakers usually contain thermal-magnetic trip units, although larger sizes can be equipped with solid state trip sensors.
塑壳断路器通常含有热磁跳脱单元，而大型号的塑壳断路器会配备固态跳脱传感器。
Mark each cord set at the locations shown in Fig. 2. For samples employing molded cord guard assemblies, a cord clamp is usually not employed.
以下的图2表明了每个插头作标记的地方是要装配的地方。样品的成型尾档要安装，电线不需用夹具装配。
Minimum scrap loss. Runners, gates, and scrap can usually be reground. Recycled thermoplastics can be injection molded.
废料损失最小化：浇道、闸道和废料通常可以重新研磨。循环热塑性塑料可以注塑成型。
Industrial plastic parts are usually requested to have high precision and complicated shapes, so it is important to control the shrinkage rates of injection-molded parts.
在这些应用场合，不仅要求塑料制品的精度高，而且塑料制品形状也比较复杂，这使得对注塑成型制品收缩率的控制变得十分重要。
Most injection-molded parts are complicated thin-shell like structure, so the thin shell finite element method is usually used to analyze the warpage and deformation of the parts.
橡塑模具制品一般具有厚度方向尺寸较面内尺寸很小且形状复杂等特点，所以在对制品进行翘曲变形分析时，就可采用薄壳有限元法。
Unless of extremely high molecular weight (1000000), can usually be dissolved and, when heated, they soften or melt so that they can be extruded into fibers or molded into desired shapes.
除非极其大量的高分子量常能液化，被加热时，会变软或融化以便能挤压成纤维或被铸成需要的模型。
