Engineering studio · Sweden

40 years of engineering experience — with you.

We design products, the machines and tools that build them and the processes that make them — from the first sketch to series production.

40+Years of combined engineering experience
12Engineering disciplines under one roof
17Kinds of projects we take on
1Partner from first idea to series production
01 — Expertise

Three disciplines. One partner that speaks all of them.

Most products fail between departments: the board that does not fit the enclosure, the part that cannot be welded, the line that was planned for a different product. We work across those lines.

01

Mechanical & Tooling

Parts, assemblies, special-purpose machines and the fixtures that build them — from lightweight aerospace components to welding jigs that hold every part the same way, every time.

  • Mechanical design
  • Special-purpose machines
  • Aerospace part design
  • Fixture & welding jig design
Electrical & Energy illustration
02

Electrical & Energy

Battery packs, circuit boards and wire harnesses designed together with the mechanics around them, so that everything fits, cools and connects.

  • Battery design
  • Electronic PCB design
  • Wire harness design
  • Electrification & retrofit
Production & Process illustration
03

Production & Process

Designs simplified for the shop floor and for series production, and factories planned and tuned so the work flows with less waste.

  • Design for manufacture
  • Simplification for mass production
  • Industrial planning
  • Process optimisation
02 — Capabilities

Some of the things we can do for you.

A sample, not a limit. If it involves mechanics, electrons or a production line — or all three at once — we would like to hear about it.

  1. 01Design a special-purpose machine from a one-page requirement
  2. 02Convert a diesel, petrol or lead-acid machine to battery-electric
  3. 03Develop a battery pack with BMS and thermal management
  4. 04Route and document a wire harness a harness shop can build without questions
  5. 05Lay out a PCB together with its enclosure, connectors and cooling
  6. 06Build welding fixtures, assembly jigs and check gauges
  7. 07Make rugged sensor electronics that survive a Nordic winter
  8. 08Simplify a product for lower cost and mass production
  9. 09Plan a production line — layout, capacity and takt
  10. 10Go from first prototype to small-series production
03 — Approach

From first sketch to series production.

Five steps, each with a clear result. Bring us in at the beginning, or at the exact point where the project got stuck.

Understand

We start with the function, the volume and the constraints — not with the CAD model.

Design

Mechanics, electronics and harnesses developed as one system, with tolerances that follow function.

Simplify

Fewer parts, fewer operations, fewer setups. Every feature has to earn its place.

Industrialise

Processes, suppliers, fixtures and work instructions so the product can be built at scale.

Optimise

Line layouts, takt and flow measured and improved after production starts.

04 — Work

Projects we take on.

From a single fixture to a complete production flow — and everything in between that needs mechanics, electronics and manufacturing to agree.

01

Special-purpose machines

Machines built for one job: test rigs, handling and lifting equipment, assembly stations and small automation cells.

Machines
02

Fixture & welding jig design

Welding fixtures, assembly jigs and check gauges that locate parts repeatably — designed around the part’s datums and the reach of the welder, robot or operator.

Tooling
03

Mechanical design

Parts, assemblies and mechanisms from concept to a released drawing package, with tolerances that follow function rather than habit.

Mechanical
04

Manufacturing guidance

Taking designed products to the shop floor: choosing processes, guiding suppliers and closing the gap between the model and what can actually be made.

DFM
05

Design simplification

Reworking existing products so they are quicker and cheaper to make — fewer parts, fewer operations — without giving up function.

DFM / DFA
06

Simplification for mass production

Turning a prototype that works into a product that can be built by the thousand: tooling-friendly geometry, assembly sequence and cost per unit.

Series
07

Aerospace part design

Lightweight structural and system components designed for strict weight, material and traceability requirements.

Aerospace
08

Battery design

Packs, modules and enclosures: cell layout, thermal paths, busbars, mechanical retention and serviceability.

Energy
09

Electronic PCB design

Schematics and board layout for control and power electronics, developed together with enclosure, connectors and cooling.

Electronics
10

Wire harness design

Routing, connector and wire selection, and manufacturing drawings a harness shop can build without questions.

Electrical
11

Electrification & retrofit

Converting diesel, petrol and lead-acid machines and vehicles to battery-electric — kits, integration and documentation.

Conversion
12

Sensor & IoT products

Rugged, battery-powered devices that measure, log and alert — built for cold, wet and remote Nordic sites.

Connected
13

Off-grid power systems

Solar and battery systems for equipment that has to work where there is no grid connection.

Solar + storage
14

Refurbishment & second life

Repairing and upgrading batteries, electronics and harnesses so useful machines stay in service instead of becoming waste.

Circular
15

Industrial planning & engineering

Production planning, line layout, capacity and work-station design for new products and growing factories.

Industrial
16

Process optimisation

Mapping how work really flows, finding the bottlenecks and waste, and fixing them with measurable results.

Lean
17

Prototype to small series

First working units, then the fixtures, suppliers and instructions to build the next fifty the same way.

Industrialise
