Wire & Cable Extrusion

Custom Wire & Cable Extrusion

Custom extrusion is useful when standard cable will not fit the connector, overmold, routing space, use environment, or marking need. An inquiry can begin with those constraints and open questions; MTTJ then develops the cable construction around downstream cutting, stripping, connectorization, overmolding, and electrical checks.

Cable construction options

The diagram separates conductor count, shielding, fillers, jacket shape, and outside diameter so extrusion requirements can be checked against later cutting, stripping, connectorization, and overmolding.

When standard cable does not fit the assembly

  • Custom cable assembly programs
  • Control and signal cable routing
  • UL wire and cable assembly support
  • Power and mixed-function cable requirements
  • Export-oriented OEM equipment programs

Conductors, shielding, jacket, color, marking

  • Starting requirements: function, routing space, use environment, and open questions
  • Conductor count and wire gauge check
  • Jacket material and color requirements
  • Shielding or drain wire requirements
  • Printing, marking, and shipment record package

Insulation, jacket, filler, shield materials

  • PVC, PE, PP, PU / TPU, TPE, PTFE, or silicone when specified for the construction
  • Specified insulation, jacket, shielding, covering, and filler materials

Cable construction

Design the cable around its downstream assembly

Conductor count, gauge, shielding, fillers, jacket, outside diameter, flexibility, color, and marking must also suit cutting, stripping, connectors, and overmolding.

Cable constructionKnown conductor count, wire gauge, shielding, fillers, and jacket requirements shape the construction; open items can be discussed before the construction is fixed.
Jacket materialFlexibility, abrasion, temperature, use environment, and target market guide material choice.
MarkingPrinting, color stripe, label, and record needs should be listed with the inquiry.
Required recordsName material, inspection, or shipment records with the inquiry when they matter.
Assembly fitCable OD, flexibility, connector fit, and overmolding needs decide whether the cable fits the target assembly.

Conductors, OD, jacket, marking, assembly fit

  • Check conductor count, wire gauge, OD, jacket appearance, marking, and color against the construction target.
  • Verify continuity and conductor identification when the cable is supplied with assembly work.
  • Inspect extrusion fit with downstream cutting, stripping, connector assembly, and overmolding needs.

Material choice, tooling, and documentation

Custom cable construction and tooling

Wire, cable, or material documentation

Specialty material effects on the specified cable construction

Qualified-supplier coordination

  • Horizontally injection-molded housings requiring horizontal molding machines
  • PCB assemblies / circuit boards
  • Specified plug, connector, or component sourcing

For quotation

Explain why standard cable does not fit

  • Why standard cable does not fit, the required function, routing space, and use environment
  • Known cable construction, jacket, color, marking, or target-market record needs
  • Assembly fit details for connectorization, overmolding, testing, packing, and any open questions
