Suitable For
  • Medical and laboratory components
  • Fluid-handling fittings and manifolds
  • Food and packaging equipment parts
  • Marine and outdoor hardware
  • Precision shafts, housings, and brackets
Consider Alternatives When
  • Projects driven only by minimum material cost
  • Thin parts without distortion planning
  • High-volume parts better suited to forming or casting

PROCESS PLANNING

Machining & Finish

RapidMfgPro reviews geometry, tolerance, material behavior, finish, quantity, and inspection requirements before matching the project with suitable manufacturing resources.

01

CNC Milling

Careful heat control and stable cutting help maintain dimensional accuracy across pockets, bores, and sealing faces.

02

CNC Turning

Well suited to fittings, valve components, shafts, sleeves, threaded parts, and instrument components.

03

Surface Finishes

Passivation, polishing, and electropolishing can support cleanliness, corrosion resistance, and appearance goals.

DESIGN GUIDE

Designing Parts in Stainless Steel

Use the following points as an early DFM checklist. Final recommendations depend on part geometry, stock form, quantity, finish, and functional requirements.

Request a DFM Review
01

Avoid unnecessary thin sections

Use balanced wall thickness and provide support around large openings.

02

Define surface requirements

Separate cosmetic, sealing, and functional surfaces on the drawing.

03

Review thread design

Allow practical thread depth, relief, and tool access.

04

Plan post-machining finish

Confirm whether passivation, polishing, or electropolishing affects critical dimensions.
