We engineer hardware
that survives production.
Mechanical design · DFM · Enclosures
Linework turns sketches and prototypes into parts a factory can build: mechanical design, tolerances, enclosures and the drawings that go with them.

02 — Capabilities
02 / 10
Fig. 02
01
Mechanical design
Parametric CAD, assemblies and part families built so the next variant takes hours, not weeks.
02
Design for manufacture
Draft angles, wall thickness and tolerance stacks checked against the process you will actually use.
03
Enclosures and electronics
Housings, thermal paths, seals and cable routing designed around the boards, not after them.
04
Rapid prototyping
Printed, machined and cast prototypes in days, each one tied to a revision and a test.
05
Production drawings
Fully dimensioned drawings, bills of materials and change notes a supplier can quote without a call.
03 — Outcomes
03 / 10
Fig. 03
What changes when the drawings are right.
01
Fewer tooling loops
Problems surface on screen, where a fix costs an afternoon instead of a mould.
02
Quotes you can compare
Every supplier prices the same, unambiguous package.
03
Faster certification
Clearances, materials and test points are planned from the first revision.
04
A design you own
Native CAD, drawings and decisions handed over at every milestone.
05
One accountable team
Mechanical design, electronics integration and supplier support in one place.
04 — Process
04 / 10
Fig. 04
Six steps, one revision history.
Every project runs on the same sequence. Each step ends with something you can hold, measure or send to a supplier.
Note
Steps 03 to 05 repeat until the test plan passes. The loop is planned, priced and visible from day one.
01
Brief and constraints
Use cases, target cost, volumes and the standards that apply.
02
Concept layouts
Two or three architectures, compared on cost, risk and time.
03
Detailed design
Full CAD with tolerances, materials and finishes.
04
Prototype
Built in the process closest to production.
05
Test and revise
Measured against the test plan; every change logged as a revision.
06
Transfer to production
Drawings, bill of materials and supplier support through the first run.
05 — Industries
05 / 10
Fig. 05
Built for teams that ship physical products.
01
Consumer electronics
Wearables, audio, smart-home devices.
02
Industrial equipment
Machine guards, control housings, fixtures.
03
Medical and lab
Handheld instruments and lab equipment, designed with compliance in mind.
04
Robotics
End effectors, sensor mounts, cable management.
05
Energy and outdoor
Weather-sealed housings, mounts and enclosures.
06
Your product
If it has parts and a deadline, send us the brief.
06 — Lab
06 / 10
Fig. 06
A lab built for fast, honest iterations.
Prototypes are made next to the desks where they are designed, so a failed test becomes a new revision the same day.
Measured, not assumed
Every critical dimension of every prototype is measured and logged against the drawing before the next revision starts.
10
CNC machining
Aluminium and engineering plastics, tight tolerances on critical features.
12
Additive
Resin and powder printing for fit checks and functional prototypes.
14
Electronics bench
Board bring-up, thermal imaging and enclosure fit.
16
Metrology
From calipers to coordinate measuring: every critical dimension checked.

Notes from the drawing board.
Short, practical articles on the decisions that make parts manufacturable, from draft angles to revision logs.
Design for manufacture
6 min read
Draft angles are a conversation with the mould
Why one and a half degrees decides whether a part releases cleanly, and how we choose draft before the first sketch is dimensioned.
Tolerancing
7 min read
Reading a tolerance stack before it reads you
Four parts, four reasonable tolerances and one gap that can close completely. A worked example of worst-case and statistical stack-ups.
Enclosures
8 min read
Designing an IP67 gasket path that survives assembly
A seal is only as good as its worst corner. How we size grooves, choose compression and keep the gasket in place on the line.
09 — FAQ
09 / 10
Fig. 08
Questions we hear before the first call.
How early should we involve you?
As early as you have a use case and a target cost. The cheapest changes happen before the first prototype.
Can you work from our existing CAD files?
Yes. We work natively in the common parametric CAD tools and can pick up from neutral formats such as STEP when native data is not available.
Who owns the design?
You do. Native files, drawings and documentation are handed over at every milestone.
Can you manage suppliers for us?
We prepare the production package and support quoting, first-article inspection and the first run with the supplier you choose.
How do you price a project?
Each phase is quoted on its own, with a fixed scope and a fixed price. You can stop after any phase.
Do you sign NDAs?
Always, before you share anything.
How long does a typical project take?
From brief to production drawings, most products take ten to twenty weeks.
Do you work remotely?
Yes. Reviews happen on shared models, and prototypes travel by courier.
