Build-to-print cable assemblies from your drawing, sample or specification
Justicia Marin supplies build-to-print cable assemblies for manufacturers, OEMs and integrators: we act as a custom cable assembly supplier and manage cable assemblies made by manufacturers in our network. You define the drawing, the sample or the requirements; we select the right manufacturer, coordinate the manufacturing and manage the delivery in the agreed quantity and lead time.
What it includes
A custom cable assembly is not just a cable with two connectors
A build-to-print cable assembly can include several conductors, branches, terminals, connectors, sleeves, protections, labels, groupings and fixing points. Our job is to translate your specification into an order that a manufacturer in the network can repeat without deviations, and to verify the result before it reaches your line.
- Cutting to length to the tolerance stated on the drawing
- Stripping and preparation of conductors according to cross-section
- Crimping of terminals with the terminal manufacturer’s tooling
- Tinning of wire ends when the application requires it
Common applications
Applications of build-to-print cable assemblies
These are the uses that reach us most often. If yours does not fit exactly, send us the specification and we will study it.
Internal machine wiring
Interconnection assemblies inside machinery and equipment: power, signal, control and communication between modules, with lengths and outlets defined by the drawing.
Interconnection between boards and peripherals
Links between electronic board, sensors, actuators, displays or power supplies, where the connector and the pitch determine the whole assembly.
Cabinets, panels and sub-assemblies
Cabling prepared to be fitted in a cabinet or panel, grouped and identified so that the fitter does not have to interpret anything.
Prototype, pre-series and repeat orders
From single units to validate a design to recurring runs with the same configuration order after order.
Starting data and criteria
What to define before requesting build-to-print cable assemblies
The quote is prepared on the information available and sets out in writing the scope the selected manufacturer can take on.
- Cutting to length to the tolerance stated on the drawing
- Stripping and preparation of conductors according to cross-section
- Crimping of terminals with the terminal manufacturer’s tooling
- Tinning of wire ends when the application requires it
- Identification by label, screen-printing or heat-shrink sleeve
- Dimensional and electrical verification according to the agreed criterion
- Individual or collective packaging according to your goods-in process
If the application is subject to requirements such as the RoHS Directive, it is advisable to define them in the specification and in the documentation requested from the manufacturer.
Decision points
Documentation and requirements for build-to-print cable assemblies
These three milestones turn an initial need into a configuration that can be ordered again without reinterpretation.
You send us the specification
Drawing, schematic, physical sample, photographs or component list. The more complete the information, the more precise and faster the quote.
You validate a sample
When the project requires prior validation, the selected manufacturer prepares a sample and you approve it on your own equipment before the agreed quantity is launched.
We supply and ensure continuity
We coordinate delivery in the agreed quantity and lead time, with the agreed documentation and the same configuration in later orders.
How we coordinate the supply
How we manage build-to-print cable assemblies
The aim is for you to approve a sample before a quantity is manufactured, so that nobody buys blind.
Review of your specification
Drawing, schematic, physical sample, photographs or component list. The more complete the information, the more precise and faster the quote.
We review and propose
We analyse feasibility, propose equivalents when a part number is hard to source and send you a quote with price, lead time and conditions in writing.
Sample approval
If the project requires prior validation, we coordinate a sample for your approval on your own equipment before launching the series.
Supply and continuity
We coordinate delivery in the agreed quantity and lead time, with the agreed documentation and the same configuration in later orders.
Coordinated manufacturing
Manufacturing of build-to-print cable assemblies with specialised manufacturers
Manufacturing build-to-print cable assemblies does not require the same processes or the same controls for a prototype as for a recurring series. That is why we do not work with a single shop: we assign each project to the manufacturer in the network whose tooling, processes and control capability fit what your specification requires.
Looking for a custom cable assembly manufacturer?
If you are looking for a custom cable assembly manufacturer, Justicia Marin coordinates the manufacturing with specialised manufacturers, selected according to the drawing, materials, connectors, volume and control requirements of the project. Production is carried out through our network; we centralise selection, coordination and supply so that you work with a single point of contact and a single order.
Criteria we use to allocate manufacturing
Type of assembly — internal machine wiring, board-to-peripheral interconnection, cabinet or sub-assembly
Connectors and terminals — involved, and the crimping tooling each part number requires
Volume and repeat orders — prototype unit, short pre-series or repeated series
Control — dimensional verification, electrical continuity and documentation, as we agree
Purchasing criterion — competitive price with verified quality, certification or lead time
From prototype to series
The same build-to-print cable assembly can start as a single unit to validate a design and end as a recurring supply. When the project requires prior validation, the manufacturer prepares a sample and you approve it on your own equipment before a quantity is launched. From then on we keep the approved configuration between orders, so that repeating does not depend on reinterpreting the drawing.
If the assembly grows in branches and connectors, it is treated as custom wire harnesses and cable harnesses. If the project starts with validation, we approach it as prototype and low-volume cable assemblies.

Services related to build-to-print cable assemblies
What this service actually covers
Justicia Marin does not manufacture in facilities of its own: we select, coordinate and verify the supply through a network of manufacturers. The specific processes, tooling and capabilities depend on the manufacturer assigned to each project and are confirmed in writing in the quote before any order. Materials, cross-sections, tolerances and test requirements are agreed case by case from your specification.
Questions before the quote
Build-to-print cable assemblies: frequently asked questions
- What do I send when I request build-to-print cable assemblies?
- You can start with a drawing, an electrical schematic, a bill of materials or BOM, a connection table or a physical sample. Also state the first quantity, the expected repeat orders, the part numbers of connectors and terminals already fixed and the documentation that must accompany the delivery. If a data point is missing for the quote, we tell you exactly which one before approaching any manufacturer.
- Who physically produces build-to-print cable assemblies?
- Physical production is carried out by a specialised manufacturer that we choose based on the drawing, materials, volume and the level of control required. Justicia Marin reviews the request, selects and coordinates that manufacturer, manages the sample and organises the delivery. You, as the customer, define the requirements and validate the assembly on your own equipment.
- Can I start from a sample without a drawing?
- Yes, a physical sample is a good starting point, provided it comes with photographs, dimensions, the function of each wire and the quantity required. Some properties, such as equivalent materials or tolerances, cannot be derived with certainty from a single piece. That is why the manufacturer makes a new sample, which you approve before the agreed quantity is released.
- Is there a minimum order?
- There is no minimum that applies to everything: it depends on the part number, the components and the assigned manufacturer. Prototypes and pre-series can have a higher unit price, and some connectors or terminals are only available per pack. When that applies, it is stated in the quote, before you take a purchasing decision.
- Which checks can be agreed before delivery?
- Depending on the project, dimensional checks, continuity testing, pin-out checks, visual inspection and batch records can be agreed. The manufacturer carries out the checks confirmed in the quote and supplies the records. Justicia Marin coordinates those arrangements and reviews the documentation; final validation in the machine remains with the customer.
- What happens if a connector or terminal is no longer available?
- We propose a documented alternative, with the relevant characteristics and any consequences for assembly. No substitution is introduced without the customer’s written approval. Once approved, the change is recorded in the configuration of the part number, so that later orders use exactly the same solution without anyone having to interpret anything.
- How can I be sure a repeat order is identical to the previous one?
- Every part number belongs to a drawing, a bill of materials and an approved revision. In later orders the manufacturer works from that configuration and every change is assessed before the new batch. That way, repeating build-to-print cable assemblies does not depend on anyone’s memory or on reinterpreting old photographs.
