Designed around
what you need.

A new product, a better-fitting component or a practical workshop tool. We turn the requirements into a design that makes sense for the job.

The details make the difference.

01

Fit

Designed around the available space, mounting points and the parts it needs to work with.

02

Function

Access, assembly and everyday use considered from the start, with prototypes to check the details.

03

Manufacture

Materials and manufacturing methods chosen to suit the application and the quantity you need.

What we can do

The right process.
A part that works.

Good engineering starts with the requirement. We choose the manufacturing method to suit it.

CAD & reverse engineering

From an existing part, measurements, drawings or photographs to a usable CAD model. Critical dimensions are checked before manufacture.

Measure · Recreate · Improve

Functional 3D printing

Engineering-grade polymers chosen for the job: PETG, ASA, PA / Nylon and carbon-fibre reinforced polymers. Functional parts, built around their application.

Fit for purpose, by design

Machined components

Conventional CNC processes when a job calls for greater strength, precision or a wider choice of materials. The design and manufacturing route work together.

Material · Finish · Precision

Sheet metal

Bespoke bent and formed components designed in CAD. A practical route for brackets, covers, panels and enclosures where sheet metal suits the application.

Cut · Bend · Form

Functional prototyping

Get a design into your hands, check the fit and refine the details. Physical iterations help resolve problems before committing to more expensive manufacture.

Model · Test · Refine

Low-volume production

One-off parts and small batches, using processes suited to the quantity. Avoid unnecessary tooling and the minimum orders that make small jobs difficult.

One part or a small run
Materials selected around the application Explore our polymer materials

PETG

A practical option for many general-purpose components, with useful toughness and chemical resistance.

ASA

Often selected for outdoor exposure because of its UV and weather resistance, with higher heat resistance than some common printing polymers.

PA / Nylon

Useful toughness and wear resistance for functional components. Moisture uptake needs to be considered for fit and dimensional stability.

Carbon-fibre reinforced

Can improve stiffness and dimensional stability. Performance depends on the base polymer, fibre content, print orientation and processing.

Strength, stiffness, temperature, chemicals and dimensional stability all matter. Final selection depends on the grade, geometry and operating conditions; printed parts can behave differently across build directions.

A straightforward process

From problem to part.

No elaborate brief required.
Start with what you have. We’ll take it from there.

01

Tell us what you need

Send photographs, measurements, drawings or an existing component. You don’t need a CAD file to start.

02

We model it

We recreate or design the component in CAD around the dimensions, interfaces and application.

03

Choose the right method

3D printing, machining or sheet metal. We recommend a practical route based on what the part needs to do.

04

Receive the finished component

After the design and quotation are agreed, we make your component, ready for the intended application.

Made to solve something

Selected work

A look at the thinking behind the parts.
Real Silver Signal CAD projects, from overall form to the smallest detail.

Functional product design

Panel Dock

A purpose-designed dock with integrated mounting points and internal features. CAD brings the interfaces, geometry and practical use together in one component.

Mechanical design

Custom enclosure

Off-the-shelf boxes don’t always suit the assembly. A bespoke enclosure models the outer form, split line and access features around the intended contents.

Assembly design & packaging

Mechanical integration

A compact assembly with nested components, recessed fasteners and closely matched interfaces. The internal layout brings the parts together within a constrained envelope.

PROJECT PREVIEW

PCB & electronics

Electronic design

From circuit requirements to board layout and physical integration. Project imagery and a detailed case study to follow.

PROJECT PREVIEW

LOOMSPEC

Automated cable testing prototype

A prototype exploring automated cable testing, bringing electronics, controls and physical design together. Case study to follow; not offered for sale.

PROJECT PREVIEW

Jigs & fixtures

Workshop tooling

Locating, holding and checking parts with purpose-made workshop tooling. An example project and its application will be added here.

Why Silver Signal

Small enough to move quickly.
Technical enough
to get it right.

Engineering, with a person behind it.

Silver Signal is run by Cameron McCurdy, an engineer with professional experience in industrial automation and controls.

That background spans industrial machinery, mechanical design, CAD, electronics, PCB design, control systems, prototyping and commissioning. It brings practical judgement to the details that make a part work.

Cameron McCurdy / Founder & engineer
01

Engineering-led

Designed by an engineer with real industrial machinery experience.

02

Low-volume friendly

One part is worth discussing. So are five. You don’t need an order for thousands.

03

Practical

The goal is to solve the physical problem. The manufacturing process follows.

04

Local, with UK reach

Based in the West Midlands, working with businesses and individuals across the UK.
