How we work
Why a cable assembly supplier like this exists
Comparing cable assembly manufacturers requires contacts and checks that most small and medium-sized industrial companies cannot sustain. Our experience inside the sector lets us know which manufacturer fits each project, which prices are reasonable and what documentation each one can really provide.
That is the reason for being of a cable assembly supplier like Justicia Marin: we coordinate supply for machinery manufacturers, OEM electronics, vending and amusement, medical equipment, technical lighting and automation, environments where the cabling is part of the final product and leaves no room for surprises.
Where we come from
Where we come from as a cable assembly supplier: years inside the industry
It was not born from a directory or a trade fair: it comes from working inside the cabling sector, buying, comparing and checking.
Origin
Years inside the cable assembly industry
We come from working inside the custom cable assembly sector: purchasing, suppliers, quality and production seen from the inside.
The problem
The market view nobody has
For a small or medium-sized industrial company it is almost impossible to know which manufacturers work well, who really certifies and which prices are reasonable. That view takes years of contacts and checks.
The network
Manufacturers known and dealt with one by one
Over those years we got to know and deal with connector manufacturers, terminal manufacturers and cable assembly manufacturers of different profiles: from those specialised in documentation and certification to the most competitive on price.
Verification
Checking good workmanship, not trusting the brochure
We check how they work through samples, documentation and previous supply experience: product quality, documentary evidence, delivery-date compliance and response to incidents.
Today
Justicia Marin: the network at your disposal
Today that network is what makes Justicia Marin a cable assembly supplier and not a catalogue: you send us your list or drawing, you define the criterion of the project and we select the manufacturer and answer for the delivery.
Versus a single cable assembler
What sets a cable assembly supplier apart from a single cable assembler
You do not depend on the capacity of a single shop. If an assembly requires another process, another volume or other documentation, the assigned manufacturer changes, not your contact.
That does not mean we can do everything: each project is checked against what the network can really carry out and the scope is agreed in writing before the order.
What we centralise
What we centralise in every supply as your cable assembly supplier
Justicia Marin centralises technical judgement, selection and purchasing, document coordination, logistics and communication. These are not departments: they are the functions we take on in every order so that you have one person to ask.

Questions about Justicia Marin
Justicia Marin as a cable assembly supplier: frequently asked questions
- Is Justicia Marin a cable assembly manufacturer?
- No. Justicia Marin is a technical B2B cable assembly supplier, not a factory. We have no production, workshop or machine park of our own. The customer defines the requirements, Justicia Marin reviews, selects and coordinates, and a selected manufacturer physically makes the cable assembly. This gives you the choice of several manufacturers with a single point of contact.
- Why work with a supplier instead of directly with a manufacturer?
- Because a single manufacturer does not cover every process, volume or documentation level equally well. For each project we compare manufacturers on capacity, cost, lead time and documentation, and you keep one point of contact, one quote and one order. If the next assembly needs something different, the manufacturer changes, not your contact person.
- Does Justicia Marin have an office or warehouse outside Spain?
- No. Justicia Marin is based in Barcelona, Spain, and serves customers internationally from there, invoicing from Spain. We have no branch, warehouse or local stock in the United Kingdom, the United States or other export markets. Lead times and transport are confirmed per order in the quote, together with the associated documentation.
- Which industries do you supply cable assemblies for?
- Industrial machinery and equipment, automation, automotive and electric mobility, rail, aerospace, defence, medical equipment, lighting, vending and amusement. For each industry we define which standards, documentation and checks apply, and we select manufacturers that can demonstrably meet them, before the first order is placed.
- How do you assess the manufacturers you work with?
- Through samples, available documentation, declared capacity and previous supply experience: product quality, documentary evidence, delivery-date compliance and response to incidents. This is not a factory audit or an approval issued by us; if your project requires a certified quality system, such as ISO 9001, that becomes a selection criterion.
- What order sizes are possible?
- From prototypes and short runs to recurring orders. There is no universal minimum order: it depends on the components and on the manufacturer. At very small quantities the unit price is higher and some connectors are sold per pack; this is always stated in the quote before you decide.
- How do I start working together?
- Send your bill of materials, drawing, part number or sample, with the quantity, the expected repeat orders and the criterion that matters most to you: price, certification or lead time. You receive an initial reply within one working day.
