Two core processes

One supplier for the parts that have to fit.

Machined components and formed sheet metal assemblies are quoted by the same engineering team, so tolerances, finishes and interfaces stay consistent across the whole build.

Capability data

What we can hold — confirmed before we quote.

We would rather decline a feature than miss it. Every critical dimension is checked against machine capability and inspection method during the quote review.

CNC maximum part sizeTBC — awaiting factory equipment list
CNC tolerance (typical)TBC — awaiting process capability data
CNC surface roughnessTBC
Sheet metal thickness rangeTBC — awaiting laser and brake specifications
Maximum bend lengthTBC — press brake tonnage and bed length
Sheet metal toleranceTBC

How it works

Five steps from drawing to delivery.

01

Upload drawings

3D model plus 2D drawing. Tell us quantity, finish and any hard deadline.

02

Engineer review

We check geometry, tolerances, material and process routing before pricing.

03

Quote + DFM

A firm price with lead time, plus notes on the features that drive cost.

04

Produce & inspect

Parts are made to the approved drawing and checked before packing.

05

Ship

Express or air freight, with packing photos and tracking.

Industries

Built for robot and automation programs, not catalog parts.

A robot or automation build mixes machined brackets, sheet metal enclosures, sensor mounts and fixtures. We quote them as one project, against one tolerance stack.

Materials

The material decides half the process.

Machinability, distortion and finishing behaviour change with alloy and temper. Each material page covers grades, cutting strategy and the finishes that work.

Case studies

Real parts, real decisions, real numbers.

Three case studies are reserved for the first delivered projects. Each one will document the challenge, the DFM change, the tolerance achieved and the lead time.

Why Protoramp

The quote is the engineering review.

Most suppliers send a price and wait for you to discover the problems in production. We put the manufacturability review in front of the price.

Start a quote
01

DFM before the price

Thin walls, deep pockets, impossible tolerances and unnecessary finishes are flagged before you commit.

02

One engineer owns the file

Your drawing is reviewed by the same person who routes the job, so the quote and the process match.

03

Confidential by default

Drawings are treated as confidential, shared only with the people producing the part, and covered by NDA on request.

04

Built in Dongguan, shipped worldwide

Direct access to the manufacturing base that supplies global hardware programs, without the layers.

FAQ

Questions engineers ask before sending files.

How fast will I get a quote?

Most quotes are returned within 24 hours on business days. Each quote is reviewed by an engineer and includes manufacturability feedback on the features that drive cost.

What files should I upload?

STEP, STP, IGES, X_T, PDF, DWG and DXF are accepted. For assemblies, upload a ZIP archive. 2D drawings are required when tolerances, finishes or inspection requirements are not defined in the 3D model.

What order quantities do you support?

We focus on 10 to 500 piece runs, including mixed projects that combine machined parts, sheet metal brackets and enclosures. Single prototypes are quoted when they are part of a larger program.

Do you sign NDAs?

Yes. We can sign a mutual NDA before you share drawings, and all customer files are treated as confidential.

Do you work with robotics startups?

Yes. Most of our target customers are 5 to 100 person robotics, automation and lab equipment teams moving from prototype to a first production build. We quote the whole bill of parts, not just a single component.

Do you ship internationally?

Yes. We ship worldwide by express and air freight, with FOB, CIF and DDP terms available depending on destination.
