Seamless Deep Drawn Cans & Pins for High-Volume Programs

Custom Industrials Company (CIC) produces precision deep drawn cans, shells, and pins for medium-to-high volume programs where seamless construction, consistent wall thickness, and a low landed cost-per-part decide the program. From alkaline battery cans and solenoid cans to capacitor cans and connector pins, CIC transforms flat blanks into seamless formed components and, as a full multi-process partner, delivers them plated, threaded, assembled, and ready for your line.

Built for Cans, Shells, and Pins at Volume

Deep drawing radially draws a flat metal blank into a die with a punch, producing a seamless hollow part with no weld seam and uniform wall thickness. For cylindrical cans and pins running at volume, that seamlessness is the whole point: no seam to leak, corrode, or fail, with material grain flow that strengthens the part. CIC’s deep-drawn process is engineered for the high-cycle, tight-tolerance production these parts demand.

Target Applications

Alkaline Battery Cans

Seamless drawn cans are the standard enclosure for alkaline and primary cells. CIC draws battery cans in steel and nickel-plated steel with the consistent wall thickness, concentricity, and clean inner surface required for reliable sealing and electrical contact at high volume.

Solenoid Cans

Solenoid cans and shells require seamless walls and tight dimensional control for consistent magnetic path and fit. CIC deep draws solenoid cans in low-carbon and magnetic-grade steels, with secondary operations such as piercing, flanging, and trimming completed in-process.

Capacitor Cans

Capacitor cans demand thin, uniform walls and clean draws in aluminum and other conductive materials. CIC produces capacitor cases with the wall consistency and surface finish needed for downstream sealing and assembly.

Connector Pins & Shells

Deep drawn connector shells and formed pins offer a seamless, high-strength alternative to machined or tube-fabricated parts at volume. CIC draws connector components in brass, copper, and steel, with plating and finishing managed as part of the program.

Deep Drawn Capabilities

Seamless construction with no weld seam
Consistent, controlled wall thickness from .005″ to .055″ or more
Dimensional tolerances typically ±.002″ to ±.005″; tighter with sizing operations
Parts with depth exceeding diameter — cups, cans, shells, and complex forms
In-process secondary operations: piercing, trimming, threading, coining, flanging, sizing
Materials: steel, stainless steel, aluminum, copper, brass, nickel alloys, and specialty materials
High-volume production capability for medium-to-high annual quantities

Convert and Save

If you currently buy these parts as screw-machined, cold-headed, or tube-fabricated components, converting to deep drawing can substantially reduce cost while improving consistency. Deep drawing removes material waste, eliminates seams, and runs at high cycle rates, which lowers piece price as volume rises. CIC will evaluate your current part and quote the converted deep-drawn version against your existing cost.

Application	Typical Materials	Why Deep Draw
Alkaline battery cans	Steel, nickel-plated steel	Seamless seal, high-volume economy
Solenoid cans	Low-carbon / magnetic steel	Uniform wall, consistent magnetic path
Capacitor cans	Aluminum, conductive alloys	Thin uniform walls, clean draws
Connector pins / shells	Brass, copper, steel	Seamless strength vs machined/tube

Frequently Asked Questions

What deep drawn parts does CIC make for high-volume programs?

CIC deep draws cans, shells, cups, and pins — including alkaline battery cans, solenoid cans, capacitor cans, and connector pins — in steel, stainless, aluminum, copper, brass, and nickel alloys, with secondary operations completed in-process.

What wall thickness and tolerances are achievable?

Wall thickness from .005" to .055" or more, with dimensional tolerances typically ±.002" to ±.005". Tighter tolerances are achievable with secondary sizing operations.

How much can I save by converting to deep drawing?

Converting screw-machined, cold-headed, or tube-fabricated parts to deep drawing reduces material waste and piece price and removes seams, with savings growing as annual volume rises. CIC will quote your converted part against its current cost.

Can CIC deliver plated and assembled cans?

Yes. CIC manages plating, threading, flanging, assembly, and inspection so you receive finished, line-ready parts rather than raw draws.

What volumes is CIC's deep drawing best suited for?

CIC's deep drawing is engineered for medium-to-high annual volumes where tooling amortizes and the per-part economics of drawing are strongest, though it also supports lower-volume precision programs.
