五金件的品種多種多樣，各種構造的都有，主要的清洗工作是除蠟、除塵、除銹、除油及肅清碎屑五個方面。人工清洗是費時又費力的，如今用工本錢又高，所以，五金件清洗日漸由超聲波清洗機來完成，特別是數量較多，構造復雜時。

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.

超聲波清洗機的優勢在于其清洗方式是將五金件浸沒在清洗槽內液體中，應用超聲波的高頻率，經過換能器轉化為高頻動能，然后作用于清洗槽中的液體介質，使液體產生空化作用，不時的構成無數個細微氣泡，并疾速爆裂，產生沖擊力沖擊物件外表，使外表污垢脫離，從而到達清洗的效果。這樣一來，只需是水能接觸到的部位都能清洗潔凈，全面徹底，不留死角。并且同時作用于五金件的各個部位，不像人工那樣一點點的清洗，因而，效率極高。

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.

運用超聲波清洗設備為五金件除蠟、除塵時，能夠用普通水加一些洗衣粉清洗即可，假如是除油，倡議添加些除油的清洗劑，大批量清洗時能夠給超聲波清洗機定制加裝濾油器，這樣水能夠循環運用，不用頻繁換水。而除銹則有特地的除銹劑。對于肅清五金件上的碎屑，假如是盲孔可能效果不太好，由于超聲波清洗主要是將外表的污垢脫離，但沒方法肅清掉。較短的通孔則完整沒有問題，能夠將孔里面的碎屑肅清掉。

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.
