电磁阀从阀结构和材料上的不同与原理上的区别，分为六个分支小类：直动膜片结构、分步直动膜片结构、先导膜片结构、直动活塞结构、分步直动活塞结构、先导活塞结构。
电磁阀按照功能分类：水用电磁阀、蒸汽电磁阀、制冷电磁阀、低温电磁阀、燃气电磁阀、消防电磁阀、氨用电磁阀、气体电磁阀、液体电磁阀、微型电磁阀、脉冲电磁阀、液压电磁阀 常开电磁阀、油用电磁阀、直流电磁阀、高压电磁阀、防爆电磁阀等。
压铸机就是用于压力铸造的机器。包括热压室及冷压室两种。后都又分为直式和卧式两种类型。压铸机在压力作用下把熔融金属液压射到模具中冷却成型，开模后可以得到固体金属铸件，初用于压铸铅字。
压铸机主要由合模机构、压射机构、液压系统和电力控制系统等各部分组成。除此之外，压铸机还有零部件及机座、其他装置、辅助装置等部分。
合模机构
驱动压铸模进行合拢和开启的动作。当模具合拢后，具有足够的能力将模具锁紧，确保在压射填充的过程中模具分型面不会胀开。锁紧模具的力即称为锁模力（又称合型力），单位为千牛（kN），是表征压铸机大小的要参数。
压射机构
按规定的速度推送压室内的金属液，并有足够的能量使之流经模具内的浇道和内浇口，进而填充入模具型腔，随后保持一定的压力传递给正在凝固的金属液，直至形成压铸件为止。在压射动作全部完成后，压射冲头返回复位。
液压系统
为压铸机的运行提供足够的动力和能量。
电气控制系统
控制压铸机各机构的执行动作按预定程序运行。
塑料加工工业中所用的各类机械和装置的总称。某些流体和固体输送、分离、破碎、磨碎以及干燥等通用性机械和设备，在塑料加工工业中也占有重要地位，所以常列为塑料机械。现代塑料机械的设计和制造，除有赖于机械工程和材料科学的发展外，特别与塑料工程理论研究的进展密切相关。
按塑料制品生产过程，塑料机械可分为塑料配混机械、塑料成型机械、塑料二次加工机械和塑料加工辅助机械或装置等四大类。塑料配混机械用于各种形式的塑料配混料的制造，包括捏合机、炼塑机（开炼机和密炼机）、切粒机、筛选机、破碎机和研磨机等。塑料成型机械又称塑料一次加工机械，用于塑料半制品或制品的成型，包括压塑机、注塑机、挤塑机、吹塑机、压延机、滚塑机、发泡机等。塑料二次加工机械用于塑料半制品或制品的再加工和后处理，包括热成型机、焊接机、热合机、烫印机、真空蒸镀机、植绒机、印刷机等。金属加工机床也常用于塑料二次加工。塑料加工辅助机械或装置用以实现塑料加工过程的合理化，包括自动计量供料装置、边角料自动回收装置、注塑制品自动取出装置、注塑模具快速更换装置、注塑模具冷却机、自动测厚装置以及原材料输送和贮存设备等。这类辅助机械或装置，已成为现代化塑料加工过程自动化所不可缺少的部分。
塑料机械的完善程度直接影响塑料半制品或制品的质量、产量和成本，因而必须能适应塑料配混和加工过程的温度和应力的变化，以及由此而引起的熔融物料性能变化，并适应化学腐蚀和机械磨损等特殊条件。塑料品级的化，工程塑料的发展，复合材料的出现，塑料产品结构大型化、轻量化和薄壁化等技术的发展要求塑料机械达到:针对制品生产目的而成套化;高速、省力、自动化，以提高制品生产效率；保证产品规格和质量误差小的精密程度；能耗低，占地少，操作维护便易而安全。

液压系统主要由5个部分组成，泵、阀、油缸、马达为核心元件。典型的液压系统由动力元件（主要是液压泵）、控制元件（主要是液压阀）、执行元件（包括液压油缸、液压马达）、辅助元件（包括油箱、过滤器、蓄能器、热交换器）、工作介质（包括矿物油、乳化液、液压油等）5个部分组成，其中泵、阀、油缸、马达的技术难度大、产品附加值高、价值占比较高，是液压系统的核心元件。
液压泵：主要有柱塞泵、齿轮泵、叶片泵和螺杆泵。其中，柱塞泵、叶片泵属于高压泵，齿轮泵属于低压泵。以柱塞泵为例，其密封工作腔构件为圆柱形的柱塞和缸体，容易得到较高的配合精度，特点是泄漏量小，容积效率高，可以在高压下工作；由于柱塞泵压力高、结构紧凑、效率高、流量调节方便，故在需要高压、大流量、大功率的系统中和流量需要调节的场合，如工程机械、矿山冶金机械、船舶、重型刨床及液压机等设备上广泛应用。
液压阀：主要分为方向阀、流量阀、压力阀。方向阀用于控制系统中的油流方向，包括换向阀、单向阀等；流量控制阀，用于控制液压系统中油的流量，包括节流阀、调速阀等；压力控制阀，用于控制系统中的油压，包括溢流阀、减压阀、顺序阀等；上述三类阀可组成各种复合阀。
液压油缸：液压缸由缸体、可移动的活塞和连接活塞的活塞杆组成，缸体两端用端盖进行封闭，端盖可采用螺纹、卡圈、拉杆或焊接等方式与缸体连接；分为双作用式、单作用式、伸缩式。
液压马达：分为单向、双向液压马达，也分为定量马达与变量马达。
