Shenzhen Zhuolida Electronics Co., Ltd. [China]

1.All kind of metals can be acid etching 2.thickness from 0.025 mm to 1.2 mm 3.tolerance:+/- 0.015 to 0.08 mm

Alloy 42 is a Nickel-Steel alloy that has a coefficient of thermal expansion that matches Silicon. Because of this property, etched Alloy 42 components are commonly used by the electronics industry. Alloy 42 etching produces parts are used for lead frames and electronic components.

It’s generally 20% of material thickness.Surface treatment for choice Silver/Gold/Tin plated, Matt finish, paint, or other surfaces treatment can be discussed when needed.

Metal etching products showcase:

1.stainless steel parts in a sheet 

2.chemical etched brass sheet ( toy model accessories)

Why choose us rather than other supplier in our China?

1.We have more than 10 years experience in the chemical etching area. Our engineers have design ability,

they can give you suggestion regarding to your high precision parts.

2. We have joined the PCMI (photo chemical etching machining institute) in the year 2007. PCMI is a American collaborative, not for profit organization for manufacturers, suppliers and customers of the photo chemical machining and electroforming industry.

3. Many materials such as stainless steel, brass, copper are imported from Europe and Japan. Advaced machines are imported from Europe too. For example, in June, 2012, We have imported the reel to reel exposure machine, this will improve our production capacity and make the products with higher Accuracy .

4. We have our own waster water treatment system, which means we are green.
