What we solve
You have an industrial need. We turn it into executable engineering.
A project, a machine, a structure, a technical problem or a piece of fabrication that needs engineering development — and right now you don't have the resources, the know-how or the capacity to resolve it. LOEN brings that technical capability: we design, calculate and document the solution until it's ready for manufacture.
Services
Everything your project needs, in one team.
From project management to design, calculations and documentation ready for manufacture. We get involved at whatever level each need requires.
Mechanical and machine design
From a functional need to bespoke machines and equipment that streamline processes and improve efficiency.
View serviceDetailed engineering
General arrangement drawings, fabrication breakdowns, bills of materials and documentation ready for the workshop, assembly and validation.
View service3D design and industrial BIM
3D modelling, BIM coordination, clash management and documentation generated straight from the model.
View serviceFEA analysis and structural validation
Finite element assessment of structures and components to ensure strength and durability.

Process diagnostics to identify opportunities for automation and improved operational productivity.
How we work
We propose, then review it with you.
We don't hand over a fixed solution on day one. We study the problem, propose an approach and validate it with you. The solution is refined step by step (technically and financially) until it's right. That way it reaches the workshop with no surprises, no cost overruns and no rework.
01
We study
We understand the problem, the constraints and what the company genuinely needs before proposing anything.
02
We propose, then review it with you
We validate every step with the company. The solution is refined until it's right, both technically and financially.
03
We deliver something manufacturable
Clear, complete documentation so the workshop can carry it out on budget and without doubts.
Projects
Equipment designed, documented and delivered.

Designs the workshop can carry out without surprises.
Frequently asked questions
What people ask us before getting started.
Do you only do FEA calculations, or full design too?
We do both. FEA calculation is part of the design process, not a stand-alone service. We can come in as external engineering at whatever level a project needs: structural validation alone, complete mechanical design, or detailed engineering based on an existing concept design.
Do you work with clients outside Jerez or Cádiz?
Yes. Our office is in Jerez de la Frontera (Cádiz), but we work across Spain. The engineering is carried out remotely, with regular technical meetings and site visits when the project requires it.
What deliverables do you provide to the workshop?
3D models, general arrangement and manufacturing drawings, fabrication breakdowns, bills of materials (BOM), technical specifications and calculation reports. All the documentation the workshop needs to manufacture with no doubts and no rework.
How long does a typical mechanical design project take?
It depends on the scope. A one-off redesign can be resolved in 2-4 weeks; the complete design of a piece of equipment with FEA calculation usually takes between 6 and 12 weeks; a full-plant BIM project can run for several months. After reviewing your case, we'll give you a realistic timeframe.
How is an engineering project quoted?
After an initial, free technical conversation in which we understand the scope, constraints and expected deliverables, we send a proposal with scope, timeline and a fixed price. We don't charge to study your case.
Tell us what you need to design, manufacture or solve.
We'll review your case and let you know whether we can help, what information we need and what the next technical step would be.
