As a rule of thumb, the cost per part for an electroform is about the same as for stampings in a 100-piece lot.
To guarantee the purity of the reagent flow, the electroform is isolated from the fluid by an internal polymer coating applied in a secondary operation.
An electroform provided a shielded answer within the existing footprint at about one-tenth the cost of a stamping.
The nickel electroform met the harsh environmental requirements of the application.
Background -- A time-consuming and often problematic aspect of making nickel electroform tooling is building the mandrels on which the nickel is deposited.
And, conventional foams frequently create porosity in the electroform that reduces the surface quality of the nickel tool.
Autoclave molds -- Nickel electroform molds are well suited for producing composite parts fabricated from thermoset epoxy and a cloth reinforcement such as fiberglass, aramid fiber, or graphite.
Resin transfer molding -- Nickel electroform molds are being used successfully in this process because they provide a hard, high gloss surface, can be heated easily, and offer a long life at a price significantly less than steel tooling.
Electroformed or electrodeposited parts made of thin layers of metal formed on a dissolving mandrel have long provided designers with unusual shapes.
How do electroforms pay off for medical equipment manufacturers?
"The combination of strength and ductility makes nickel uniquely suitable for flexible bellows as well as rigid electroformed components," Hazlitt says.
