CNC milling machine producing a precision aluminum component

Precision manufacturing partner

Custom Parts Manufacturing

CNC machining, sheet metal, finishing and assembly support for engineers and purchasing teams developing custom components. Start with your part geometry, then review the manufacturing and inspection scope.

Project guide

Have a custom part to make?

Start with the drawing and the job your part needs to do. Review a similar part requirement below, then plan the first batch and the checks needed before approval.

Part requirements

Review a Similar Part Requirement

Explore three illustrative requirements. The images are examples, not customer projects or inspection results.

CNC machining

Machined housing & cover

A housing that must mate with another component

Review the internal pocket, mating faces, hole positions and the drawing revision together. Mark the fits that control assembly; define finish and masking where dimensions must be protected.

Sheet metal fabrication

Formed mounting bracket

A bracket that must fit in its installed position

Share the formed model, sheet thickness, mounting-hole locations and installed condition. Resolve bend and coating requirements before comparing quotations.

Inspection planning

Part with critical interfaces

A part whose acceptance depends on specific features

Identify the critical faces, bores and relationships. Agree the measurement method, sampling and report scope against the drawing before releasing the first batch.

Quality commitment

Quality. Precision. Trust.

Discuss the checks and records needed for your part before confirming the production scope.

Define the evidence with your order

  • Drawing revision and acceptance criteria
  • Inspection checkpoints and report scope
  • Material and finish records, when specified
Review Quality Planning

Application considerations

Decision guide

Find the right starting point for your part

Choose a service from the geometry you need to make. If the route is undecided, send the part function and available files so the alternatives can be discussed together.

Review points for your project
Your starting pointExploreInclude in the review
A solid part with pockets, faces or boresCNC machiningCAD, drawing revision, material and functional interfaces
A formed bracket, panel or enclosureSheet metal fabricationFormed geometry, thickness, bends and installed hardware
A part requiring a protective or cosmetic finishSurface finishingSubstrate, environment, visible faces and protected fits
Several components that must work togetherAssembly and integrationBOM, mating interfaces and functional checks

A process name is only the starting point. Confirm the manufacturing scope, inspection records and delivery requirements against the actual part before releasing an order.

Your next step

Prepare the First Order

Bring the drawing revision, evaluation quantity and acceptance requirements together before releasing a first batch. The RFQ guide covers sample approval, quotation scope and repeat-order changes.
