Engineering office and custom metal parts manufacturer

Your name on the product, not just on the invoice

We design, we build and we advise. From a photo or a sketch, through CAD design and a prototype, to a production run carrying your mark — with no minimum order and no tooling cost.

We do this for wholesalers and specialist retailers, machine builders, rail, motorsport and test laboratories.

Machine component manufacturing drawing
01

We design

Mechanical structures in 3D CAD, with structural and modal (FEM) analysis. We start from a photo, a sketch or a description — a technical drawing is not required.

Finished metal part
02

We build

A prototype from a single unit, then the production run. CNC machining, laser cutting, welding and surface finishing — a finished product carrying your logo.

FEM numerical simulation
03

We advise

Material, process and design choices matched to real cost and batch size. We tell you what is not worth building — before you pay for it.

Private label

The same product. A different owner of the margin.

The same shelf, the same manufacturer, the same datasheet. Your customer compares the one thing that differs — price. Private label takes the product out of that comparison.

Catalogue resale

The margin is set by the manufacturer. Your competitor buys the same product at the same price. The only lever left is discount.

Private label

You set the price. There is nothing to compare against, because the product exists only at your company. In some sectors margins on own-brand products reach 60–70%.

Four barriers that usually stop a smaller player

They apply to plastic injection moulding and a container from the other side of the world. They do not apply to metal made locally.

Minimum order quantity

With us you start from a single unit. No MOQ.

Tooling cost

No moulds or tooling to pay for before the first part exists.

Importing from the other side of the world

We produce locally — you talk to the engineer directly, in your own time zone.

16 weeks and frozen capital

Prototype in 2 weeks, first production run in 6.

How it works

From a photo to a product carrying your mark

You do not change supplier and you do not order a batch blind. You start with one unit you can put in front of your customer.

1

Photo or sketch

Send whatever you have. It does not have to be a technical drawing.

2

CAD design

We draw it and quote it. 3 working days.

3

Prototype — 1 unit

In your hands after 2 weeks.

4

Test with your customer

Revisions are made before the run starts.

5

Run with your mark

A product with your logo.

Where it is made

Local production decides how fast revisions happen

On a first production run, revisions are the rule rather than the exception. Where the product is made decides whether they cost a day or a quarter.

Local
S-POL

We come to you, you handle the prototype, you talk to the engineer directly.

Import from Asia
The other side of the world

A design change means an email, another time zone and another shipment.

Our work

What we already produce

Sectors that do not tolerate "nearly right". Your bracket or frame is not a challenge for us.

Rail industry component

Rail industry

Trackside components and fittings for rail infrastructure. Repeatable production runs, stainless steel, service in extreme weather.

Surveying equipment component

Surveying

Adapters, sleeves and mounting components for surveying instruments. Tolerances that measurement repeatability depends on.

Hand earth auger

Earth augers

Augers and drills for soil boring — from flight design to a complete tool with handle.

Agricultural harrow design

Agricultural machinery

Harrows and tillage machine components. Welded structures working under heavy cyclic loads.

Slow-moving vehicle frame

Slow-moving vehicles

Load-bearing frames and subassemblies for slow-moving vehicles — design, strength calculations and manufacturing.

Gearbox — exploded view

Drives and gearboxes

Housings, shafts and gears. Design of a complete drive unit, including bearing selection.

Motorcycle licence plate bracket Motorcycle workshop stand

Motorcycles, motorsport and workshop equipment

Plate holders, brackets and adapters, workshop stands and jigs, and structural components for rally cars. Single units and small runs — including for machines out of production for years.

Test rigs and test equipment

A separate line of work: complete machines for vibration, shock and environmental testing, designed around a specific setup and test profile. We deliver them to laboratories, R&D departments and manufacturers across the EU.

Vibration test fixture

Vibration test fixtures

Aluminium and steel, up to 800–1000 mm and 100 kg. First natural frequency above 1500 Hz, confirmed by FEM.

Vacuum chamber for a shaker

Vacuum chambers

Stainless steel, mounted directly on the shaker armature, with measurement feedthroughs and viewports.

Complete machine — exploded CAD view

Complete machines

Machines designed and built in full — with drive, mechanisms and controls.

Protective camera enclosure

Protective enclosures

Reinforced aluminium for ballistic, pyrotechnic and crash testing.

What exactly we can make

From a simple part to a complete machine

01

Simple metal components — where your turnover actually is

We always start with one product — the one you sell most often.

Furniture and fit-out

Legs, frames, brackets, runners, mounting components.

Building materials

Mounting systems, angle brackets, holders, anchors, fittings.

Appliances and electrical

Frames, chassis, housings, installation brackets.

Machinery and tools

Adapters, guards, trolleys, fixtures, spare parts.

02

Complex machines and equipment — when a part is not enough

Complete builds with drive, control and documentation. We design them from requirements, not from a catalogue.

Test rigs

Machines for vibration, shock and environmental testing, built around a specific test profile.

Special-purpose machinery

Equipment for tasks no off-the-shelf product on the market covers.

Assembly and inspection stations

Jigs and stations for repeatable assembly, measurement and quality control.

Lead times and cost

From enquiry to first production run

DAY 0

You send a photo or a drawing

DAY 3

You have a quote and a sketch

WEEK 2

Prototype in your hands

WEEK 6

First run on the shelf

The same route through import: 16+ weeks and full prepayment up front.

The classic route
tens of thousands of euros
Moulds and tooling 500 units prepaid Shipping and customs Warehousing before you sell the first unit
Through S-POL
from a few hundred euros
Design included One unit, no MOQ No mould or tooling cost You decide on the run only after the test

The entry cost depends on the part and the sector — we confirm the figure in a quote within 3 working days.

First step

You are not deciding on a private label today. You pick one part and send us a photo of it.
