Heavy-duty parts for the industries that build things.

Automotive volume and quality systems are the foundation. The same plants now ship into trucks, equipment, and the power and cooling infrastructure behind data centers.

Aluminum and iron steering knucklesDie cast engine mount brackets

OEM & Tier 1

Automotive

Chassis, powertrain, driveline and structural components built to IATF 16949 and full PPAP. Our network has supplied programs across trucks, SUVs, minivans and passenger cars, on internal combustion, hybrid and battery electric platforms.

  • Control arms
  • Engine & transmission mounts
  • Exhaust & turbo manifolds
  • Differential cases
  • Brake components
  • Oil pans & covers
  • Rockers & siderails
  • Battery enclosure parts
  • Tow hooks

Best fit: high-volume machined iron and aluminum, compressed launches, and takeovers from a struggling supplier.

Class 4 to 8

Commercial vehicle & heavy truck

Heavy-section iron and machined assemblies for medium and heavy trucks, buses and trailers, where durability matters more than anything on the print.

  • Axle beams & carriers
  • Cab mounts
  • Engine mount systems
  • Brake drums & anchor brackets
  • Trailer axle components
  • Pinion flanges & yokes
  • Bearing caps
  • Hubs

Best fit: ductile iron with heavy machining, rubber-to-metal mount assemblies, multi-year programs.

Mission-critical facilities

Data center & electrical infrastructure

Hyperscale data centers and semiconductor fabs run on chilled water loops, fire protection and power distribution. That means thousands of iron fittings, valve bodies and pump housings, most of which need machined bores, grooves and sealing faces before they can ship. Our network delivers them machine-complete, from one supplier, under one quality system.

  • Grooved coupling & fitting bodies
  • Valve bodies
  • Pump volutes & casings
  • Circulator housings
  • Chiller & cooling loop components
  • Fire protection fittings
  • Switchgear & grid hardware castings
  • Structural brackets

Best fit: gray and ductile iron castings machined complete, low to mid volumes, fast-track construction schedules.

Construction & mining

Off-road & construction

Parts for equipment that works in dirt, heat and vibration all day. Thick sections, tight hydraulic bores and steering components that can't fail in the field.

  • Hydraulic valve housings
  • Pump bodies
  • Steering gear housings
  • Knuckles & hubs
  • Pivot & mounting brackets
  • Counterweights
  • Axle sub-assemblies

Best fit: machined ductile iron, heavy brackets, low to mid volumes with long program life.

Tractor pulling an implement across a plowed fieldCast iron bearing caps with studs

Farm equipment

Agriculture

Tractors, combines and implements use the same castings and powder metal parts as heavy trucks, at lower volumes and with seasonal swings. Our plants are used to both.

  • Bearing caps & adapters
  • Gearbox housings
  • Hubs
  • Brackets
  • PM gears & sprockets
  • Bushings
  • Steel tube structures

Best fit: iron castings and powder metal at low to mid volumes.

Water, HVAC & plumbing

Water & flow control

Municipal water, commercial HVAC and plumbing products are iron castings with critical machined features. Seats, threads, grooves and sealing faces all have to hold pressure.

  • Hydrant bodies
  • Gate & check valve bodies
  • Pump housings
  • Drainage bodies
  • Grooved fittings
  • Elbows & tees

Best fit: gray and ductile iron, machined complete and leak tested.

Machined iron housing with threaded portsPrecision length measuring gauge

ITAR registered

Defense

ITAR-registered machining and assembly for ground vehicle and equipment programs, with the documentation and controlled data handling those programs require.

  • Ground vehicle castings
  • Bearing caps & adapters
  • Housings
  • Brackets
  • Machined forgings

Best fit: build-to-print machined iron and steel, controlled technical data.

Machined bearing housings with flanged bolt patternsMachined flange with sealing face and bolt pattern

Rail, hydraulics & power

Industrial & rail

Compressors, hydraulics, small engines, appliances and rail equipment all run on cast and machined iron. Our foundries already serve these markets.

  • Rail adaptors
  • Pillow blocks
  • Compressor housings
  • Hydraulic castings
  • Crankshafts
  • Small engine parts

Best fit: medium to high volume gray and ductile iron.
