Quote a Custom Part

Send 2D/3D drawings (STEP, PDF, DWG, IGES). Machined, cast, forged, stamped, fabricated or molded—quoted by engineers. Response in 24 hours, quotation in 1–3 days.

  • CNC machining, casting, forging, fabrication, molding
  • Material certificates & dimensional reports
  • High mix / low volume or automated high volume

Upload drawings

Consolidate a BOM or Assembly

Already buying 5, 10, 20 parts that get assembled together? Send us the BOM. We make or source every component, build the fixtures, assemble, test, serialize and pack—so you receive one tested assembly under one purchase order.

  • Multi-process sourcing & supplier management
  • Reduce labor-intensive assembly and testing costs
  • US inventory (own warehouse in California), VMI

Where We Fit Best

Assemblies we build every day

We don’t claim “any module for any industry.” These are the assembly families where our processes, fixtures and test benches are already proven.

Housing, bearing & seal assemblies

Machined or cast housings with bearings, seals and shafts installed, then press-fit, leak- or rotation-tested.

Welded frames & machine structures

Robot-welded frames delivered with bushings, fasteners, casters, brackets and other hardware installed.

Motor, gearbox & actuator assemblies

Housings, adapters and shafts built around specified motors and reducers, with run-in, current and noise checks.

Fluid & electromechanical assemblies

Tube sets, manifolds, enclosures, sensors, harnesses and PCBAs assembled, function-tested and prepared for installation.

Supplier Consolidation

One managed program instead of fragmented purchasing.

We manufacture what we do best, work with trusted specialist suppliers for the rest, and manage everything under one program.

One quality owner

Incoming inspection, supplier quality and final release are managed under one control plan.

Consolidated Logistics

Fewer shipments and receipts, with optional California safety stock, VMI or Kanban release.

How BOM consolidation works

Smart Manufacturing · ProvenCell®

Proven in our factory.
Deployed in yours.

For selected projects, we use robotics, machine vision and digital traceability to manufacture parts and assemblies. Through ProvenCell®, we can also prove a dedicated production system at CSMFG and transfer the complete capacity to your floor.

For selected CSMFG manufacturing projects

  • Robot-controlled assembly where the process benefits
  • AI vision inspection and automatic sorting
  • Serial-level test records and traceability

For selected capacity-transfer projects

  • Process, tooling, automation test run at CSMFG
  • Transfer and installed to your shop floor with our continuous support.
