Sourcing solutions
What Do You Need Made?
Start from the problem rather than the process. Each page explains how the work is quoted, what suppliers need from you, and how to prepare an RFQ that gets accurate answers.
Obsolete & replacement parts
Obsolete Replacement Parts
When a part is obsolete, the question is no longer where to buy it — it is who can make it again. Most obsolete parts are remade from a sample, a worn original, an old drawing or some combination of the three, by a machine shop or fabricator that routinely takes on single-piece work.
Discontinued Parts Manufacturing
A discontinued part is usually still perfectly manufacturable — the market for it simply stopped justifying a production line. Contract shops fill that gap by making the part in the quantity you actually need, from your sample or documentation.
Legacy Equipment Parts
Legacy machinery often outlives its documentation. Presses, conveyors, packaging lines and process equipment from the 1970s through the 1990s are frequently sound mechanically while individual components are unobtainable. Remaking those components is ordinary work for a competent machine shop or fabricator.
Spare Parts Manufacturing
A spares programme turns unplanned downtime into a scheduled purchase. Rather than sourcing under pressure, you identify the components that actually stop production, have them documented and manufactured once, and requote them on a known drawing whenever stock runs low.
Rush Replacement Parts
When a line is down, sourcing behaves differently. The objective is not the lowest price — it is the shortest credible path to a working part. That means sending complete information immediately, approaching shops that have capacity today, and being explicit about what you will trade away for speed.
Custom Replacement Part Sourcing
Most replacement parts fall into one of a handful of process families, and picking the right one before you enquire saves a round of wasted quotes. The decision usually follows from the part's form, material and quantity rather than from what the original was made by.
Reverse engineering
Reverse Engineering Replacement Parts
Reverse engineering turns an existing part into a manufacturable definition: a model, a drawing, a material call-out and a set of tolerances. Done properly it produces something reusable for years. Done carelessly it produces a copy of a worn part.
Manufacturing Without Drawings
Plenty of manufacturing starts without a drawing. Shops quote from samples, hand sketches, photographs and verbal descriptions every week. What they cannot quote from is ambiguity about function, quantity and what "good" means for the finished part.
Making a Part From a Sample
A physical sample is the most complete specification most buyers ever provide. It carries geometry, material evidence, finish and wear history in one object. The job of the enquiry is to tell the shop which of those attributes matter and which are incidental.
3D Scanning to Replacement Part
3D scanning captures complex form quickly, which makes it valuable for castings, housings, ergonomic shapes and anything with freeform surfaces. It is less useful for prismatic parts with bores and threads, where conventional metrology is faster and more accurate.
Replacement Part Material Selection
Material is the specification buyers most often leave blank, and it changes both price and performance. When the original material is unknown, it can be identified by testing or inferred from function — and occasionally it should be changed deliberately.
Low volume & prototype
One-Off CNC Machining
Single-piece CNC work is a different business from production machining. The cost is programming, setup, workholding and inspection — the cutting itself is often a small fraction of the total. Shops that welcome one-off work are usually organised around short setups and experienced machinists rather than long unattended runs.
Small-Batch CNC Machining
Between the one-off and the production run sits the batch: ten to a few hundred pieces, repeating a few times a year. This is where quoting gets interesting, because setup cost spreads across the batch and material buying starts to matter.
One-Off Machine Shop Sourcing
Not every machine shop wants single-piece work, and sending a one-off to a production shop wastes everyone's time. The shops that thrive on it are typically job shops, toolrooms and repair shops geared to short setups, manual capability alongside CNC, and fast turnarounds.
Small Production Runs
A small production run is the first point at which manufacturing decisions become commercial decisions. Quantity, tooling, process choice and inspection interact, and the cheapest quote is not always the cheapest programme once you account for rework and the second order.
Bridge & Pilot Production
Bridge production supplies real parts while production tooling is being built or validated. Pilot production proves the process at low volume before scaling. Both exist to keep a launch moving without committing to tooling that the design may still outgrow.
Low-Volume Injection Molding
Injection molding at low volume is a tooling conversation. The part price is often modest; the question is what mould to build, in what material, for what expected life — and whether molding is the right process at your quantity at all.
Low-Volume Sheet Metal
Sheet metal is well suited to low volume because cutting is tool-free: a laser or punch works straight from your flat pattern. Cost concentrates in forming setups, secondary operations and finishing rather than in tooling.
Prototype Metal Enclosures
Enclosures look simple and quote badly when under-specified. Cutouts, hardware, finish, sealing and labelling account for most of the cost, and each of them needs to be stated before a fabricator can give you a price you can rely on.
Small-Batch Welded Assemblies
Welded assemblies at low volume are built around fixturing and sequence. Frames, skids, guards and weldments can be produced accurately in small numbers, but only if the drawing tells the fabricator which dimensions must hold after welding.
Prototype to Production Sourcing
Prototypes prove the design; production proves the process. The transition fails most often on details that did not matter in ones and twos: tolerance capability, material sourcing, inspection and the repeatability of finish.
Sourcing from a drawing or sample
Find a Manufacturer From a Drawing
With a drawing or CAD file in hand, sourcing becomes a matching exercise: find shops whose process, size range and quantity comfort match the part, and give all of them the same package so the quotes are comparable.
Sourcing From a CAD File
A CAD model defines geometry but not requirements. Tolerances, material, finish and inspection live outside the model unless you have a disciplined model-based definition. Closing that gap before you send files is what produces comparable quotes.
Preparing a Manufacturing RFQ
Most quoting delay comes from missing information, not from busy suppliers. An RFQ that states quantity, material, tolerance, finish and timing up front is quoted in days; one that omits them becomes a week of email before anyone prices anything.
