Electroforming is a process of producing metal/stencil/parts by depositing atom by atom. Through this process, a highly accurate replica is produced from a mandrel or master surface.

Electroforming also stands out in terms of high repeatability and complexity. Electroform stencils can be manufactured to any thickness from 2-7 mil with 0.01-mil increments.

StenTech has the capacity to produce electroform stencils, foils and nickel parts, as well as 3D parts, which have been serving aerospace, military and medical industries with high quality products exceeding the expectations of our partners/customers for many years.

Benefits:

• Precise and controlled process
• Custom thickness can be achieved
• Very smooth trapezoidal walls
• Better release of paste compared to laser-cut or chem-etched
• Provides fine and ultrafine pitch apertures with paste transfer efficiencies at 95% and above
• Provides longer stencil life (electroform stencils are generally 1.5 times harder than stainless steel of comparable thickness)
• Nickel electroform offers lower coefficient of friction compared to steel, which allows better roll of paste and decreases squeegee wear
• Stencils with large aperture counts/dense images can be done without metal distortion (no heat transfer)
• Absolutely no burr (no need of buffing or polishing)
• Thickness of stencil range from 0.001" to 0.008" in 0.0001" increments and with multi-steps
• Positional accuracy 0.002" over 16" image area
