Photo Chemical Etching Advantages

Writer: admin; Source:SinoGuide Team; Date:2016-05-31

Summary: The PCM process advantages for thin metal precision parts include the following:



Photo Chemical Etching Process Advantages.

The process is very effective for industries where miniaturization, part weight and extreme tolerances are necessary. Thin metal parts are fabricated and manufactured using photo chemical machining, chemical blanking, micro chemical milling, and the photo etching process, which are generally classified under the banner of photochemical machining or “PCM”. PCM,” photo etching, chemical etching, acid etching, chemical machining, metal etching.

RFI and EMI Shielding Etching Parts


Advantages for thin metal precision parts include the following: 

1. Low cost tooling advantages: Primarily done on a computer, and aided by CAD/CAM software thus minimizing the expensive mechanical operations costs.

2. Speed of delivery: time = money. Our photo etching will save on both time and money. Part deliveries are typically 1-2 weeks. Contact our engineering department and sales specialists for quick turn quotes.
 
3. Metal properties and structural integrity of manufactured parts: Metals’ properties and structural integrity are maintained as a unique advantage; part configuration is maintained without surface burring.
 
4. Tooling modifications: Using CAD/CAM software and computers, the photo etch design can be modified at a minimal cost to the OEM. This allows the OEM designer to take full advantage of Sinoguide’s production speed capabilities, in order to build a prototype at a low cost and provide a fast turn around time.

5. Easily fabricate thin metal parts out of various metals and alloys:A wide variety of metals ,alloys, and composite materials can be used to produce precision thin metal parts quickly using the SinoGuide PCM process.

6. Complex shapes are easily produced: SG can produce thin metal parts formed into complex, 3 dimensional, precision shapes.
 

The Etching Process- Save Money, Get Better Quality

The etching process also has added benefits in that it produces completely stress and burr-free results, unlike other manufacturing methods, such as laser cutting, water-jet cutting or EDM wire erosion.
 
In terms of the accuracy achievable, the acid etching process is extremely competitive with other metal manufacturing methods, with tolerances from +-0.010mm offered, depending on the material type and thickness. Features can also be positioned to an accuracy of +-5 microns.
 
The process uses ferric chloride as the etchant to cut the component profile, and the hardness of the material is not a factor, as we can acid etch both very hard tool steels or annealed substrates.
 
Design changes are very easy to rectify with the photochemical machining process. We simply print the new required profile outline onto an acetate photo-film soft tool, and up-issue the drawing revision, as appropriate.
 
As the profile image is simply printed onto the metal sheet, the complexity of the design is not an issue. Even very intricate designs, such as metal meshes and very small feature component parts, can be manufactured easily and quickly, which also lends itself perfectly to frequently changing parts or research and development projects.
