Custom Automation Parts
Custom brackets, fixtures, machine components, and replacement parts for production equipment.
Automation parts cover custom machine components, fixtures, brackets, nests, stops, mounting plates, housings, and replacement details that only make sense in the context of the surrounding equipment. The quote needs to record that context clearly enough to avoid building a dimensionally plausible part that still fails at installation.
Applicability
When this service is the right fit
Use the service label only after the drawing, quantity, material, and inspection needs support it. The process should follow the RFQ evidence, not substitute for it.
Assemblies where mounting pattern, datum transfer, cable or sensor clearance, and repeatability matter more than simple envelope size.
Service parts where the original OEM source is unavailable and the buyer needs the RFQ tied to their current machine revision.
Builds that combine machining with light secondary operations, hardware installation, or controlled fit-up notes.
Materials and constraints
What should be confirmed before quoting
Material callouts and geometry constraints change price, route, and inspection burden together. Keeping them explicit is more useful than generic capability language.
Materials commonly reviewed
- Aluminum and steel for structural brackets, machine frames, guards, and repeatable fixture elements.
- Engineering plastics when low friction, electrical isolation, or controlled contact surfaces are part of the design intent.
- Bronze or wear materials when sliding interfaces or sacrificial contact zones are specified.
- Buyer-defined grades only; if corrosion resistance or electrical behavior matters, the RFQ should say so directly.
Frequent quoting constraints
- Automation parts often fail in quoting when the drawing omits machine-side references, installed orientation, or which surfaces actually locate the part.
- A replacement part may need legacy-hole matching, shim logic, or asymmetrical edge conditions that are invisible in a detached photo.
- Hardware, dowels, sensors, and cable pass-through features should be defined as controlled interfaces, not informal shop additions.
- Packaging and labeling can matter because a machine-down replacement part is often installed immediately on arrival.
Inspection planning
Define acceptance before production starts
Inspection language should identify the features that make the part useful in assembly, not just the dimensions that happen to be easy to measure.
Name the mounting datums, dowel locations, and interface features that determine whether the part installs without adjustment.
If the part supports motion, define the dimensions that govern travel, stop position, or parallelism to the machine reference.
For replacement work, state whether the inspection target is the drawing nominal, the as-built sample, or controlled offsets approved by the buyer.
Call out any installed hardware checks, thread verification, or surface-protection requirements that must be completed before shipment.
RFQ checklist
Send the information that actually changes the quote
A complete RFQ package reduces delay more effectively than broad capability claims. The checklist below is the minimum useful technical handoff for this service.
Equipment context
Include assembly screenshots, install orientation, and machine-side references when available.
Functional surfaces
Mark contact faces, stop surfaces, shim locations, dowel bores, and mounting patterns.
Replacement logic
State whether the part must match an existing sample exactly or follow a revised controlled drawing.
Attached hardware
List inserts, studs, bushings, or purchased hardware that should be installed before shipment.
Handling needs
Define any rust prevention, labeling, protective caps, or kit grouping required for installation-ready delivery.
Acceptance method
Confirm whether dimensional records, trial-fit notes, or installation-critical checks are required.

Common quote-stage questions
What makes automation-part RFQs different from generic machined-part RFQs?
The surrounding equipment context. A bracket or fixture detail often looks simple in isolation but depends on exact hole transfer, clearance, and installed orientation. That context needs to be part of the quote basis.
Can a replacement part be quoted from a worn sample?
A sample helps, but the RFQ should still say whether the target is the sample’s current condition or a restored nominal geometry. Otherwise the quote can accidentally preserve wear, drift, or undocumented field modifications.
Should packaging details really appear in the RFQ?
Yes when installation timing is sensitive. Replacement machine parts may need rust protection, edge protection, labeling, or grouped kits so the receiving team can install them without re-sorting or re-cleaning.

Attach the controlled package, mark the features that drive acceptance, and state the records required with shipment. That creates a usable manufacturing RFQ for this service.
Start RFQPublished standards
Where these requirements are written
A drawing arrives under the ISO or the ASME convention depending on where it was drawn. ProtoRFQ claims no approval under any of these; the standard that governs a project is the one named in the RFQ.
- ISO 2768-1:1989 — general tolerances for linear and angular dimensions without individual indications, in four tolerance classes.
- ASME Y14.5-2018 — the GD&T standard defining the symbols, datum references and profile tolerances an inspection plan is built from.
- ISO 21920-2:2021 — surface texture parameters; a finish requirement is only checkable once it is written in one of them.
