Photo Chemical Etched Stainless Steel Heating Element/Heating Coil/ heating film

Photo Etching is also called metal etching, chemical etching, chemical milling, photo etching, photochemical machining, or chemical machining.

Applicable Scope: Etching processing various kinds of metal, alloy, and stainless steel plates. Used in petroleum, chemical, food, and pharmaceutical precision filters, electronic industry lead frames, metal substrates, precision optical parts, and complex metal accessories.

Applicable Materials: Stainless steel sheet, copper sheet, aluminum foil, ferronickel alloy, iron sheet, Nickel silver, titanium alloy, etc.

Capable of shaping varieties of materials with the thickness of 0.03 to 1.2mm such as stainless steel, copper, aluminum, zinc and iron sheet by etching, half-etching, both sides and pattern imprinting without the need of hardware mold manufacturing charge.

Production Process: Film(CAD output) → Materials Ready → Pre-treatment → DRY FILM (Lamination) → Exposure → Developing → Drying → Etching → Stripping → Checking, Packing, Delivery

• Precision etching with smooth surface on both edges.
• No embossment, no convex-concave, no burnisher burr, no warping.
• Any complicated pattern or geometric figure is available.
• 100% Eco-friendly materials (Stainless steel, Brass, or Copper).
• Strict tolerance control: +/- 0.005mm to +/- 0.01mm.

• Short lead time for samples and mass production.
• High precision and tight tolerance (up to 0.02mm for 0.1mm material).
• Low tooling cost compared to traditional hardware molds.
• Burr & Stress-free manufacturing method.
