CádizVillamartín · Andalucía
Project engineering, not a closed catalogue
We work with capabilities, not fixed models.
The difference is where we start. Instead of pushing whatever machine is in stock, we design the equipment around your real process: your product, your format, your production rate and your plant.
In-house design
Mechanical and electrical engineering developed entirely in-house. Every machine is drawn, calculated and validated before it is built.
Custom manufacturing
Open ranges, not a fixed list. We adjust capacity, materials and formats to what your application really demands.
A single point of contact
From design to integration and after-sales service. One team answers for the whole line, with CE marking and documentation.
What we develop
Four areas, one engineering team.
We cover your product's full cycle: preparing it, packaging it and automating the whole line — plus solving what no standard machine covers.
01
Packaging Machinery
Dosing, filling, capping, labelling and conveying of liquids, semi-liquids and viscous products.
View the area 02Process Machinery
Product preparation and treatment. Mixers are our speciality: agitated tanks, emulsification and dosing.
View the area 03Custom Solutions
When no standard machine exists, we design it. We also modernise existing equipment through retrofitting.
View the area 04Automation & Complete Lines
Turnkey integration: PLC programming, electrical panels, SCADA and commissioning of the whole installation.

For machinery manufacturers
Do you build machinery? We are your external engineering office.
We also work for other packaging machinery manufacturers and integrators: project-based or hourly engineering that absorbs your workload peaks without growing your team. Your product stays yours — we work under NDA and never commercialise client designs.
Mechanical and electrical design
SolidWorks/Inventor design and EPLAN schematics ready for your workshop: assemblies, manufacturing drawings and BOM.
PLC · HMI · SCADA automation
TIA Portal and WinCC Unified programming, electrical panels and commissioning at your customer's site — under your brand.
Calculation, documentation and CE
Line sizing, technical file, risk assessment and CE marking. The reinforcement you need to close the project.
Confidentiality by contract: NDA — drawings and know-how stay with you. We never compete with your catalogue.

Engineering from start to finish.
SOLINDAC Ingeniería was born in Villamartín (Cádiz) with a clear idea: to solve the whole project. We design and bring to life the machinery industry needs, with full control of the process — from the drawing to commissioning.
Quiénes somos
A multidisciplinary technical team that understands the industrial process from start to finish.
Under the SOLINDAC brand we take on packaging, process and automation machinery projects, backed by a network of trusted suppliers and partners. Our goal isn't to sell a machine, but to solve a production problem.
That way of working — listen first, design afterwards — is what lets us deliver equipment that fits your plant, not the other way round. Every project is drawn, calculated, built and commissioned with the same team behind it.
Nuestra manera de trabajar
We don't work from a fixed catalogue of models. We work with capabilities — we start from your real process and design the equipment around it.
That means we don't force your product to fit a standard machine. We adjust capacity, materials, formats and control to what your application really needs. Custom engineering, not a closed catalogue: it's the difference that shapes every project.
Por qué SOLINDAC
Four commitments in every project.
01
In-house engineering
Mechanical, electrical and control design developed entirely in-house — never resold.
02
Custom manufacturing
Open ranges: each machine adapts to your product, your format and your capacity.

FAQ
Frequently asked questions
What we are usually asked before starting a project.
Is the engineering your own, or do you distribute third-party machinery?
The engineering is always our own: every machine is designed from your product and your line, not from a closed catalogue. And when the project calls for it, we also coordinate complete fabrication with trusted workshops, right through to commissioning.
Do you only supply complete lines, or individual machines too?
Both. From a single machine — a filler, a mixer, a capper — to a complete turnkey line with its automation, electrical cabinet and commissioning.
Can you modernise (retrofit) a machine I already own?
Yes. We assess the mechanical and control condition of the equipment and propose the upgrade that pays off: new automation (PLC and HMI), safety upgrades or the redesign of specific assemblies. And if a retrofit is not worth it, we say so.
What information do you need to prepare a proposal?
The essentials: your product (viscosity, temperature, behaviour), container formats, target output, available space and the desired level of automation. With that we prepare a technical proposal built around your case.
Do you work outside Andalusia? And in Portugal?
Yes. We deliver projects across the Iberian Peninsula, with documentation and support in Spanish, English and Portuguese.
What lead times does a typical project have?
It depends on the scope: a control retrofit can be completed in a few weeks, while a complete line takes several months across design, fabrication and commissioning. The exact schedule is set out in the technical proposal.
Do you work for other machinery manufacturers?
Yes. We provide engineering-office services for manufacturers and integrators: mechanical and electrical design, PLC/HMI programming, calculation and CE documentation. Always under NDA — your design and your customer remain yours.
