Line Card
PrecisionForm is a vertically integrated precision parts manufacturer based in Lititz, Pennsylvania, serving automotive, firearms, aerospace, electrical, and industrial programs. Engineers and procurement teams working on high-volume fastener, pin, fitting, and bushing programs rely on PrecisionForm when they need a domestic supplier with cold forming, CNC Swiss, multi-spindle, and finish machining all under one roof.
The shop runs CNC Swiss lathes for tight-tolerance work, multi-spindle automatics for cost-efficient mid and high-volume production, and cold heading up to 6-die for near-net-shape forming at scale. Finish machining, thread rolling, grinding, and broaching round out the capability set. That combination means PrecisionForm can take a program from prototype through automotive-scale production without changing suppliers.

CNC Swiss
Best for complex, tight-tolerance parts and prototype through early production runs where design iteration is likely.
- Bar diameters 0.040 to 1.50 in (1 to 38 mm)
- Cross and axial holes, slots, fine threads in a single setup
- Typical tolerance ±0.0005 in, tighter on review
- Strong fit for families with design iteration
Multi-Spindle
High part rate with multiple tools in cycle — the cost-efficient path for mid and high volume programs.
- Multiple tools cutting simultaneously for strong COGS at volume
- Inline operations: drill, mill flats and slots, cutoff forms, thread roll and cut
- Ideal when annual usage grows beyond Swiss economics
Cold Heading (up to 6-die)
Near-net-shape forming for heads, collars, and ribs. Best value at 25k pieces per run and above.
- Wire range 0.060 to 0.625 in typical
- Progressive forming for heads, collars, and ribs
- Coin, size, and grind for precision surfaces
- Significant material savings versus full turning
Finish Machining and Grinding
Secondary operations that blend headed and machined features to print spec.
- Critical OD/ID, grooves, faces; secondary drill, slot, broach
- Thread rolling and cutting; centerless and OD grinding
- Blends headed and machined features to print

A great fit for
- Programs scaling from prototype through volume with a cost-down path from Swiss to multi-spindle or cold heading
- Parts with threads, cross holes, grooves, flats, or slots requiring secondary operations
- High-volume fasteners, pins, fittings, and bushings needing throughput and competitive piece price
- Automotive and industrial programs requiring PPAP and lot traceability
- Programs benefiting from cold heading for material savings at 25k pieces per run and above
×
Not the right fit for
- One-off jobs requiring same-day or next-day turnaround
- Parts with diameters or lengths outside the bar and wire ranges
- Requests requiring offshore or non-domestic manufacturing
- Programs with no print or documentation requirements
