Meridian Dredge Instrument is a medical device developed by traditional Chinese medicine meridian theory.It can acupuncture, massage, beat and knead automatically. Compared with medicine treatment, meridian dredge instrument has less harm to human body, except a little radiation. Therefore meridian dredge instrument is popular in recent years.Many medical equipment manufacturers are investing more in the R&D for it. Then prototype is needed when developing new product.
 
 
A few days ago, we made a project about a prototype for Meridian Dredge Instrument. Its material is ABS. The process includes CNC machining, polishing, pad printing and high gloss. Now we’d like to introduce it to you in detail.
 
 
CNC machining: in command of program, the tool of CNC machine moves on the ABS material as per the designated path to cut off the spare parts and finally we could get the rudiment of prototype.

 
CNC Machining

 
Polishing: there are some burrs on the prototype after cnc machined. It needs to be hand-deburred by sandpaper to make it smooth.


 
 
Painting: spraying a layer of paint on the surface of prototype to make it more exquisite. It is worth mentioning that the display screen of prototype was made with transparent PMMA and sprayed a layer of transparent black paint on it.
 
 
Pad printing is to print the logo or words on the surface of prototype using pad printing machine. The words on the press-key of prototype is made by pad printing.


 
 
High-gloss: covering a layer of UV paint on the surface of prototype to make it brighter.
