Transparent, predictable
and fully documented.
We know ordering custom parts overseas can feel like a black box. That’s why every project at Purniss runs on a clear 5-stage workflow, real shop-floor photo logs, outgoing QC verification, and one application engineer who owns your order from quote to delivery.
No black-box production
One Clear 5-Stage Workflow
We don’t hand your files off to an anonymous broker queue. Every order follows five structured stages — combining our in-house engineering and outgoing QC team with audited specialist shops — so you always know where your parts are and what happens next.
- 24h DFM review
- Vetted specialist shops
- Shop-floor photo logs
- Global DDP / DAP
- Gate 1You approve the DFM notes, process route, and firm quote before any material is cut.
- Gate 2For batch runs, you sign off on the first-article sample before series production starts.
- Gate 3You review our outgoing CMM and dimensional inspection report before the shipment leaves.
Select a project route on the right, then click or hover any milestone to see what our engineers handle, what documents you receive, and where we wait for your sign-off.
CAD Evaluation & Free DFM Review
An application engineer inspects your STEP/IGES model and 2D drawing for thin walls, draft angles, tool access, and tolerance risks—returning a practical markup alongside your quote.

Quality You Can Verify
As a growing manufacturing partner, we don’t ask you to take our word on quality. Before your order is packed, our QC room verifies critical GD&T callouts on our CMM alongside pin, thread, and roughness gauges — and shares the actual measured data, mill certs, and fixture photos with you.
- Ballooned drawingCritical callouts numbered on your 2D drawing so report rows map 1-to-1.
- CMM & gauge dataNominal spec, tolerance band, and actual measured values recorded before dispatch.
- Material traceabilityEN 10204 3.1 mill test certificates and RoHS/REACH declarations on request.
- Shop-floor photo logReal photos of your parts on the fixture, under inspection, and slotted in foam cartons.
- CMM accuracy
- ±0.005 mm

Direct engineer-to-engineer line
One Engineer, Start to Finish
No script-reading sales reps or ticket queues. You work directly with an English-speaking application engineer who understands GD&T, machining setups, and surface treatments — whether you need to adjust a tolerance or check on a Friday dispatch.
- Design changes & DFM
- Schedules & shipping
- Photo & video updates
- Reports & corrective actions
The same application engineer who reviews your CAD model coordinates the specialist shop floor, checks the first-article sample, and signs off on your outgoing QC report.
- RDFM
- RProto
- RProduce
- RInspect
- RShip
Can we tighten the tolerance to ±0.01 mm on the central bore without delaying Friday's dispatch?
Absolutely. We'll finish-bore that feature on the 5-axis cell to hold H7 and mask the bore during anodizing. I've updated the DFM and shop routing sheet—no impact on Friday's ship date.

Built for repeat orders
Every File, One Project Vault
From the initial DFM markup to the outgoing CMM report and packing list, every record is version-controlled, signed off by your engineer, and kept in one project folder. When you reorder, we pull the same locked CAM setup, fixtures, and masking notes so Batch 2 matches Batch 1.
- Versioned revisions
- Locked CAM setups
- Incoming-QC ready
- Smooth reorders
Every inspection report references your part number, drawing revision, and engineer sign-off, making it straightforward for your QA team to verify parts at incoming inspection.
- CNC program v3
- Fixture F-12
- CMM routine
- Packaging spec
Unlocks once the order is delivered. The archived program, fixture and CMM routine let a repeat order skip DFM and prototyping.
