Disruption planning

Supply Chain Shocks

A single plant, a single port, a single supplier is one failure away from stopping your line. We run three plants, 127 CNC machines and two countries so your parts keep moving when the usual route does not.

Where it hurts

Four failures we hear about after every disruption

Each one is a schedule loss, not a headline.

01

A single plant goes quiet

One lockdown, one power cut, one labor shortage, and your machined housings stop. You find out when the tracking number does not update, then spend a week hunting for capacity that is already booked.

02

The second source cannot hold tolerance

You qualify a backup shop in a hurry. First articles arrive at ±0.05 mm instead of ±0.005 mm, so the mating bore will not seat and the whole lot is scrap. Re-qualifying costs more than the outage did.

03

Nobody can see the risk until it lands

Purchase orders, WIP and inspection status live in three spreadsheets. A supplier slips two weeks and the first signal is a missed ship date. By then expediting is the only option left.

04

Freight and tariff swings eat the margin

One port backlog or one duty change moves landed cost by double digits overnight. Quotes built on last quarter's route stop working, and the program runs at a loss until someone renegotiates.

How we build resilience in

Redundancy you can inspect, not a slide in a deck

Two countries, 127 machines, and a documented handoff between them.

Leader in Cnc Machining Service China
Capacity redundancy

When one site stalls, the work moves

Our three wholly-owned plants cover 7,600 m² in Dongguan plus a factory at No.3 Joo Koon Circle, Singapore. Because the same programs, fixtures and inspection routines exist at both locations, a job can be re-routed without redoing first-article approval from zero.

That matters for supply chain shocks that hit one region and not another. A port strike, a power restriction or a customs backlog on one side usually leaves the other side running. We decide the split at quoting time, not after your line goes down.

Sourcing depth

Material and process options that do not depend on one vendor

A disruption rarely stops at machining. It hits the mill that rolls your 7075 plate or the anodizer that handles your housings. We keep qualified routes for aluminium, stainless, steel, copper alloys, titanium and engineering plastics so a single shortage does not freeze the program.

In-house finishing is the other half. Anodizing, plating, powder coating, black oxide, bead blasting and laser marking run through qualified partners we audit, which means we are not waiting on a broker to find a coating line during a shortage.

Which sourcing setup fits your risk profile

Pick the row that matches how much downtime your program can absorb.

FAQs

Questions buyers ask during a disruption

How quickly can you move a job from one plant to the other?

Because programs and fixtures are duplicated between Dongguan and Singapore, the transfer is a scheduling decision rather than a re-qualification project.

Send the drawing set and the current revision. We confirm which site has open capacity and give you a new ship window in the same reply.

Do you require a minimum order quantity to open a backup source?

No. There is no minimum order quantity, so a backup can start with one part.

That lets you validate a second source with a small order instead of committing to a full production run you may not need.

What tolerance can the second source actually hold?

The same ±0.005 mm (±0.0002 in) as the primary site, because both use the same machine classes and inspection routine.

If your print is looser, say so at quoting. Chasing unnecessary tolerance adds cost and time with no benefit to the assembly.

Which materials are at risk of a single-vendor shortage?

Aluminium plate, titanium and specialty stainless are the usual bottlenecks, along with anodizing capacity.

We keep qualified routes for 6061-T6, 7075, 304, 316L, 17-4PH, Ti-6Al-4V, Inconel and PEEK so a shortage in one grade does not stop the program.

How do I know the parts were actually inspected?

Every lot goes through raw material check, in-process monitoring and final inspection before shipment.

Reports are available on request. Ask for them at order placement so the format matches what your quality team files.

Can you keep drawings confidential while we qualify you?

Yes. Uploads are secure and confidential, and we sign an NDA on request before you release production files.

We work under ISO 27001:2022 information security controls, which covers how files are stored and who can open them.

What is the realistic lead time when freight is disrupted?

Machining and finishing run at 3–5 days to ship, with production starting within 24 hours of approval.

Freight is the variable we do not control. Having two shipping origins means you can pick the lane that is actually moving that week.

When is dual sourcing the wrong choice?

For one-off prototypes and very low volumes, splitting a job across two sites adds coordination cost for no real risk reduction.

Use one site until the part is on a repeating schedule or the line stops when it is missing. Then split it.
