Which Process Should I Choose?

Three common starting points. If you are not sure, send the drawing and we will recommend one.

I have a prototype

Validate form, fit and function before tooling.

Start with prototyping →

I need metal parts

CNC for precision parts, sheet metal for enclosures and frames.

Process

From Drawing to Production in 5 Steps

01

CAD & DFM

Upload STEP, STL or PDF. An engineer reviews manufacturability and risk.

02

Process & quote

We recommend molding, CNC, sheet metal, casting or prototyping and price it.

03

Tooling / programming

Mold design, CNC programming or sheet metal flat pattern, then first parts.

04

T0 / first article

T0 samples, dimensional report, fit check and correction plan.

05

Production

SPC-controlled production, inspection, packaging and global shipping.

FAQ

Choosing a Manufacturing Process

How do I choose between injection molding, CNC and sheet metal?

It depends on volume, material, geometry and tolerance. Send your drawing and volume; we will recommend the lowest total-cost process.

Can you take a part from prototype to production?

Yes. We can prototype, make bridge tooling and then move the same part into hard tooling and production.

What tolerances can you hold?

CNC to ±0.005 mm, sheet metal and urethane casting to ±0.1 mm, injection molding to ±0.05 mm standard and ±0.01 mm precision.

What is the minimum order quantity?

Prototypes from one piece. Production volumes depend on the process; send your annual volume for a recommendation.

What documentation do you provide?

DFM feedback, material certificates, FAI, dimensional reports, PPAP and full traceability where required.
