High precision aluminium etching filter mesh

High precision aluminium etching filter mesh

Photo etching, also known as chemical etching or metal etching, is a highly precise, tightly controlled corrosion process used to produce complex metal components with very fine detail.

The photo etching process offers a cost-effective alternative to stamping, punching, laser and waterjet cutting when machining precision components from thin gauge metals - up to 1.5mm thick - including stainless steel, nickel and nickel alloys, aluminium, copper and copper alloys and hard-to-machine metals such as titanium. When component integrity is critical, photo etching is often the only suitable metal machining technology as metal temper and magnetic properties are unaffected.

The products we make are widely used in electronics, personal care, sensors, precision measurement, hardware, semiconductor, optical, communications, automotive engineering, medical, aerospace, petrochemical, precision engineering industries, etc.

Using photo etching not laser cut or stamping. By photo etching, the edges of the springs is smooth without any burr. By stamping, the mold cost is high and the thin products will be out of shape easily, but photo etching will keet the thin products flat enough.

Using photo mask, the product pattern is copied on the metal material by the exposing machine. Then, etching it by liquid medicine. The distortion and burr will not be made by such chemical process, and the material could be kept flat. After the final washing process, the products will be very clean.

Half EtchingBy exposing different patterns to the front and back side of the material, it is possible to etching single side of the metal material. The etching depth is about 2/3 of the material thickness.

Taper EtchingBy etching different sizes from the front and back side of the material, a tapper hole could be made. The tapper shape could be adjusted.

No Burr and DistortionUnlike machining or pressing, since etching is corroding the metal material by the chemical liquid, the burr or distortion will not be occurred during the process.

• From prototype to mass productionOur production line both for making prototypes as will as mass production to meet a broad range of customer needs.
• No bridge etchingEtching without making bridges on products is possible. Suitable for spring or complex pattern which can not have bridge.
• Lined Material EtchingBy using the no bridge etching technology, we could also etching the lined material for heater of heat or others products. And the adhesive could be peeled off without heat is efficient for production. Big size or roll material is also available. Please contact us for the details.
• Available for Large SizeThe max. size for our etching equipment is 1050*1750mm.
• High Precision Mesh or Perforated Plate by EtchingMetal mesh products or perforated metal could be produced by etching and weaving technology of Nippon Filcon. Small quantity or large size is also available.
• Short Lead time for Urgent CaseThe short lead time (from 2 days ) for prototype is possible. Please contact us for the details (material, thickness, pattern, etc..)
