五金件的品种多种多样，各种构造的都有，主要的清洗工作是除蜡、除尘、除锈、除油及肃清碎屑五个方面。人工清洗是费时又费力的，如今用工本钱又高，所以，五金件清洗日渐由超声波清洗机来完成，特别是数量较多，构造复杂时。

There are many kinds of hardware, all kinds of structures. The main cleaning work is to remove wax, dust, rust, oil and debris. Manual cleaning is time-consuming and laborious, and now the cost is high. Therefore, hardware cleaning is increasingly completed by ultrasonic cleaning machine, especially when the number is large and the structure is complex.

超声波清洗机的优势在于其清洗方式是将五金件浸没在清洗槽内液体中，应用超声波的高频率，经过换能器转化为高频动能，然后作用于清洗槽中的液体介质，使液体产生空化作用，不时的构成无数个细微气泡，并疾速爆裂，产生冲击力冲击物件外表，使外表污垢脱离，从而到达清洗的效果。这样一来，只需是水能接触到的部位都能清洗洁净，全面彻底，不留死角。并且同时作用于五金件的各个部位，不像人工那样一点点的清洗，因而，效率极高。

The advantage of the ultrasonic cleaning machine is that the hardware is immersed in the liquid in the cleaning tank. The high frequency of ultrasonic is applied to convert the high frequency kinetic energy into high frequency kinetic energy through the transducer, and then act on the liquid medium in the cleaning tank to make the liquid cavitate. From time to time, numerous tiny bubbles are formed and burst rapidly to produce impact force on the surface of the object, So that the appearance of dirt off, so as to achieve the effect of cleaning. In this way, as long as the water can contact the parts can be cleaned, comprehensive and thorough, leaving no dead corner. And at the same time act on all parts of the hardware, unlike a little bit of manual cleaning, therefore, the efficiency is very high.

运用超声波清洗设备为五金件除蜡、除尘时，能够用普通水加一些洗衣粉清洗即可，假如是除油，倡议添加些除油的清洗剂，大批量清洗时能够给超声波清洗机定制加装滤油器，这样水能够循环运用，不用频繁换水。而除锈则有特地的除锈剂。关于肃清五金件上的碎屑，假如是盲孔可能效果不太好，由于超声波清洗主要是将外表的污垢脱离，但没方法肃清掉。较短的通孔则完整没有问题，能够将孔里面的碎屑肃清掉。

When using ultrasonic cleaning equipment to remove wax and dust for hardware, it can be cleaned with ordinary water and some washing powder. If it is to remove oil, it is suggested to add some cleaning agent to remove oil. When cleaning in large quantities, it can be customized to add oil filter to the ultrasonic cleaning machine. In this way, the water can be recycled without changing water frequently. And derusting has special derusting agent. About cleaning debris on hardware, if it is a blind hole, the effect may not be very good, because ultrasonic cleaning is mainly to remove the dirt from the surface, but there is no way to clean it. The short through-hole is complete and can remove the debris in the hole.
