Here are the benefits of photo etching when compared with other manufacturing processes:
Cheap flexible tooling for fast prototyping and design changes.
Metal properties stay unaltered
Low-cost repeatability for substantial production of parts with complex designs
Burr-free components with low tolerances
Swift turnaround
Low-cost Flexible Tooling - Fast Prototyping
Photo etching tooling is digital, in contrast to expensive standard methods which include stamping. In addition, tooling is generated within hours; whereas, challenging tooling can take weeks. A repeating pattern of a part's dimensions is designed by means of CAD software. Then, a photoplotter machine produces two pieces of mylar film using the digital image. One piece is placed on leading of the metal sheet plus the other on the bottom.
This low-cost method enables the engineer to create a repeating pattern onto the tooling film to maximize the number of components per sheet. Digital tooling is simple to modify for prototype development and therefore substantially reduces project time. Aspect revisions are a snap which makes it excellent for prototypes or quick runs. There is certainly no wear around the tooling and it may be stored for the life with the component.
Metal Properties Stay Unaltered
Other machining methods which include laser cutting and stamping can alter the metal properties with heat or mechanical strain through production. Having said that, together with the photo chemical etching approach, the internal structure on the metal remains unchanged. A chemical etchant dissolves the unwanted element sections. There is no point of contact with chemical metal etching like heat, or difficult tooling.
The hardness, grain structure, and ductility in the metal are unaffected. This benefit is considerable for the function of several industrial elements that rely on precision, low tolerances, and high conductivity. And because of this, chemical etching is ideal for electronic elements including electrical contacts, connectors, EMI/RF shielding, pins, and terminals.
Low-cost repeatability with complex designs
The tooling is designed to yield as numerous pieces because the part design will enable. Because of the repeatability inside the chemical etching method, substantial production runs are a reduced cost and more quickly option in comparison to stamping and laser, specifically when it involves complicated designs. Parts with holes or slots as well as other intricate functions are created with no extra charge.
In addition, we are able to etch company logos, portion numbers or other identifying marks at no additional expense. The photo etching tooling remains the identical irrespective of whether it really is for one portion or possibly a million. As industrial components get smaller sized, photochemical machining will save you time and money.
Burr-Free Tight Tolerances
Yet another chemical etching advantage is the fact that completed components are assured to be free from burrs or mechanical tension. Other processes generally leave burrs or micro burrs that may interfere with aspect function. By way of example, clean, smooth surfaces are desirable for electronic mating components. The absence of burrs also decreases unwanted friction and heat to ensure peak overall performance for other forms of electronic and RF microwave elements.
Photo etched parts eradicate the need for the pricey secondary deburring operation that may perhaps be vital for other manufacturing processes.
A further metal etching advantage will be the capability to hold low tolerances with all kinds of metals. The etching speed is very carefully controlled to achieve the preferred tolerances. Due to the fact a photo tool will generate an exact replica of a part's dimension and will not put on like challenging tooling, it is actually straightforward to maintain necessary tolerances.
Speedy Turnaround
The elimination of mechanical tooling and its extended lead time, the absence of surface burrs and deburring specifications, plus the speed with intricate designs makes photo chemical etching a quickly manufacturing procedure for prototypes or big production.
