Bespoke OEM Parts
Your Drawing. Your Spec. Your Part.
Fully custom-manufactured components and assemblies built to your exact engineering drawing — any material, any process, any combination. From single prototypes and obsolete-component replacements to revision-locked production supply. No catalogue constraints, no configured-option compromises: if you can draw it, we can make it, from our Ahmedabad manufacturing facility with a full first-article inspection report on every new part.
A catalogue part is not an OEM part. It is a compromise your product inherits permanently.
Specifying a catalogue component into an OEM product because nothing bespoke exists at the right price point or lead time is a decision that costs more than it saves. Catalogue parts are designed to a price, not to a dimension. They change without notice when the supplier revises the tool. They go end-of-life when the supplier's volume economics change. Every revision your product then requires — because the catalogue part changed — is an engineering change, a validation, a re-certification, and a production hold. A bespoke OEM part is designed to your dimension, manufactured to your drawing, and never changes unless you approve the change. The total cost of ownership of a bespoke part — across the product's service life — is consistently lower than the total cost of managing catalogue part substitutions.
If the part doesn't exist, we make it. If it's obsolete, we reverse-engineer it. If it's wrong, we fix the drawing.
We receive bespoke OEM enquiries in three categories. The first is a complete drawing and a request to manufacture. The second is a requirement — a function that needs to be fulfilled — and a request to design and build. The third is a failed or obsolete part that needs a replacement and the original drawing no longer exists. We handle all three. For the first, we review, quote, and manufacture. For the second, we work from your functional specification, produce a drawing for approval, and manufacture. For the third, we measure the physical sample, produce a reverse-engineered drawing for sign-off, and manufacture a replacement that is dimensionally and functionally identical to the original.
One supplier for the full build — not five suppliers you have to manage into alignment.
A bespoke assembly typically requires multiple processes: machining, printing, coating, cutting, laminating, hardware installation, and testing. Each process managed by a separate supplier introduces a seam where things go wrong: tolerances stack, coatings arrive late, lamination is done to the wrong revision, hardware is installed by someone who hasn't read the drawing. When we manage the complete build — all processes under one roof or under our direct subcontract management — there is one point of responsibility, one drawing in force, one revision controlling everything. The assembly that arrives at your production line is the assembly that was designed, approved, and quality-checked as a unit.
What We Build
Bespoke OEM Engagements by Type
One-off replacements, pre-production pilots, multi-component assemblies, and long-run production supply — the engagement model scales to the requirement without a minimum order constraint.
Replacement & Obsolete Component Re-Manufacture
When an OEM component goes end-of-life and the original tooling no longer exists, we reverse-engineer from a physical sample or partial drawing, produce a dimensioned CAD drawing for approval, and manufacture a drop-in replacement to the same functional and dimensional specification. Supplied with full dimensional report and revision-marked drawing.
Low-Volume Pilot & Prototype Parts
Pre-production pilot quantities — 1 to 50 units — to validate fit, form, and function ahead of full production tooling commitment. Prototype parts are built to the same drawing and material spec as production, not simplified versions, so the prototype approval is a valid first article for the production run.
Custom OEM Sub-Assemblies
Multi-component assemblies that combine sheet materials, printed overlays, membrane switches, metal hardware, and connector interfaces into a fitted unit — supplied under a single OEM part number with a revision-controlled drawing and bill of materials, ready for direct installation into the client's product.
Long-Run Production OEM Supply
Ongoing production supply of approved bespoke components — monthly or quarterly call-off orders against an agreed annual volume, held on a revision-locked drawing, with fixed unit pricing and agreed lead time. Suitable for OEMs who need a reliable, revision-stable supply of custom interface components across the product's service life.
Why Bespoke
Bespoke OEM vs Catalogue vs Semi-Custom
The supply model determines whether you own the specification — or whether the supplier's catalogue decisions own your product.
| Property | Catalogue Part | Semi-Custom / Configured | Bespoke OEM Part |
|---|---|---|---|
| Drawing & Specification | Generic catalogue spec; fixed dimensions; no client drawing | Configured from option matrix; limited outside standard variants | Your drawing, your revision, your exact dimension — no compromises |
| Material & Process | One material grade; one surface finish; no substitution | Limited material choice; finish options within catalogue range | Any material, any process combination — confirmed at FAI |
| First Article Inspection | Not applicable — catalogue part; no client-specific FAI | Dimensional check against option spec; not against client drawing | Full FAI report against your drawing before production begins |
| Revision Control | Supplier-controlled; changes without client notification | Option matrix versioned; component-level changes not disclosed | Your drawing revision is the manufacturing document — no change without approval |
| Minimum Order Quantity | Catalogue MOQ — typically 100+ units minimum | Configuration MOQ — typically 25–50 units minimum | No MOQ floor — 1 unit prototype accepted |
| Repeat-Order Repeatability | Subject to supplier revision; no guarantee of dimensional identity | Within current option matrix; discontinued options break supply | Fixture retained; drawing locked; identical part on every order |

How We Handle Bespoke
No Drawing? No Problem — We Convert Requirements Into Manufacturing-Ready Data
Most bespoke OEM enquiries arrive not as a complete DXF file, but as a photograph of an existing part, a hand-sketch on A4, a verbal description of what needs to replace a failed component, or a competitive sample. We convert all of these into a dimensioned manufacturing drawing — measured, modelled, and drawn by our engineering team — and submit it for your approval before a single unit is cut. The approved drawing becomes the revision-controlled document of record for every subsequent production run, so the part you receive in production year three is dimensionally identical to the part you approved in the first-article sign-off.
First Article Inspection — Every New Bespoke Part Proven Before Production Begins
No bespoke part enters production without a first article inspection (FAI) report signed off against the drawing. The FAI measures every dimension on the drawing, confirms surface finish grade, verifies colour match to PMS or RAL reference, checks functional performance (switch continuity, backlight uniformity, adhesive bond strength, connector mating), and documents the results in a format the client can submit to their own quality system. The FAI unit is either returned to the client as a reference sample or retained in our quality library. Production begins only after written approval. No exceptions.
Repeat-Order Repeatability — The Same Part, Every Time, to the Same Drawing
A bespoke OEM part is only useful if it is identical across every delivery — from the first prototype to the thousandth production unit three years later. We hold every approved bespoke part under drawing revision control, retain the production fixture and tooling for the life of the part, and store the colour-matched print profile, adhesive specification, and material grade against the part number. When a repeat order arrives six months after the last delivery, we pull the same drawing revision, the same fixture, the same material certificate grade, and produce the part to the same standard as the original approval.
Mixed-Material, Multi-Process Assemblies — One Supplier for the Complete Build
Most bespoke OEM components are not single-material, single-process parts. A typical bespoke interface assembly might require: laser-cut aluminium backplate, CNC-routed acrylic overlay, UV-printed legend layer, screen-printed colour fill, die-cut polyester adhesive, assembled with PEM inserts installed in-process, with a connector tail terminated to the client's PCB header pin-out. Managing five suppliers for five processes on one assembly introduces revision mismatch, delivery misalignment, and integration errors. We perform every process in-house — or under our direct subcontract management — and supply the complete assembly as one part number on one delivery note.
