Custom Development

Application-specific cable protection developed for performance, manufacturability and scale

Custom Cable Protection Built Around the Application

Customization should solve a defined technical or commercial problem. It should not add complexity without measurable value. MJ FLEX begins by identifying the critical requirements, separating mandatory functions from preferences and evaluating whether a standard, modified or fully customized product is the most appropriate route.

Our engineering, production and quality teams consider product performance together with material availability, manufacturing stability, inspection methods, MOQ, lead time and future production volume. This helps ensure that an approved prototype can become a reliable production product.

When Custom Development Is Appropriate

  • No standard product fits the required cable or hose dimensions
  • The operating environment requires a different material or material combination
  • Existing sleeving does not provide enough coverage, overlap, flexibility or durability
  • A product needs special flame, thermal, electrical, shielding or environmental performance
  • The current product is expensive, difficult to source or subject to long lead times
  • The assembly process requires custom lengths, closures, identification or packaging
  • An OEM needs a controlled specification for repeat production

Custom Development Inputs

INPUT WHAT TO PROVIDE
Application data Industry, equipment, installation position and service conditions
Dimensional data Bundle range, connectors, branches, bend radius and available space
Performance targets Abrasion, temperature, flame, electrical, UV, chemical, burst or shielding requirements
Reference information Samples, drawings, datasheets, competitor part numbers and test reports
Commercial requirements Forecast, MOQ, target cost, packaging, lead time and annual volume
01

Custom Materials

Material customization is used when standard PET, nylon or fiberglass products cannot deliver the required combination of temperature resistance, mechanical protection, chemical compatibility, insulation, shielding, weight or cost.

Material Options

MATERIAL GROUP POSSIBLE OPTIONS
Engineering polymers PET, PA6, PA66, PPS, PEEK, PE, PP and ABS
Fluoropolymers PFA, PTFE, PVDF and related high-performance materials
High-strength fibers UHMWPE, aramid fibers, Nomex® and Kevlar®
Inorganic fibers Fiberglass and basalt fiber
Conductive materials Stainless steel, copper, tinned copper and plated copper wire
Functional combinations Silicone-coated systems, laminates and hybrid textile-metal structures

How Materials Can Be Customized

  • Use a different polymer, fiber, wire or coating system
  • Combine materials to balance flexibility, strength, heat resistance or conductivity
  • Add UV-resistant, flame-retardant or other functional formulations where technically feasible
  • Select filament diameter, yarn type or metal-wire construction for the target performance
  • Evaluate an alternative material to improve availability or reduce total product cost

Important Material Considerations

Raw-material ratings do not automatically define the performance of the finished sleeve. Braiding density, wall thickness, coating, color, conditioning and processing can influence test results. Compliance and performance must therefore be confirmed for the final product specification.

02

Custom Sizes

The correct size must protect the assembly without creating excessive material consumption, insufficient coverage, difficult installation or unstable overlap. MJ FLEX can develop sizes around the actual cable, wiring harness or hose geometry.

Dimensional Customization

  • Nominal inner diameter or flat width
  • Minimum and maximum bundle diameter
  • Expansion range
  • Wall thickness
  • Overlap ratio
  • Product width
  • Cut length or roll length
  • Large-diameter construction
  • Special dimensional tolerances
  • Connector and branch-point clearance

Sizing by Product Type

PRODUCT TYPE KEY SIZE CONSIDERATIONS
Expandable braided sleeving Expansion range, installed coverage, connector clearance and product consumption
Self-closing sleeving Nominal size, bundle range, overlap retention and bend behavior
Woven wrap / hook-and-loop sleeve Flat width, finished circumference, closure allowance and cut length
Fiberglass sleeving Inside diameter, coating thickness, wall thickness and electrical requirements
Heat shrink tubing Supplied diameter, recovered diameter, shrink ratio and recovered wall thickness
Hydraulic hose sleeve Hose outside diameter, sleeve fit, wall thickness, length and burst-containment target

Information Needed for Accurate Sizing

For the best recommendation, provide the minimum and maximum bundle diameters, connector dimensions, branch points, bend radius and available installation space. A physical cable or hose sample is valuable when the geometry is irregular or the fit is critical.

03

Custom Structures

Product structure can be as important as material choice. By adjusting the way fibers, filaments, coatings and closures are arranged, we can target specific installation and performance requirements.

Structural Parameters

STRUCTURE AREA CUSTOMIZATION FOCUS
Braided construction Carrier count, braid angle, density, filament diameter and expansion
Woven construction Yarn combination, thickness, edge treatment and surface coverage
Self-closing construction Overlap ratio, opening force, closure retention and bend performance
Layered construction Single or multiple layers for added coverage, insulation or mechanical protection
Closure system Open, split, hook-and-loop, zipper, adhesive or other project-specific closure
Functional integration Metal wire, foil, coating, laminate, tracer yarn or reinforcement elements

What Structural Changes Can Improve

  • Abrasion resistance and surface coverage
  • Flexibility and repeated movement
  • Expansion and connector installation
  • Overlap and closure stability
  • Noise reduction and anti-rattle behavior
  • Electrical insulation or EMI shielding
  • Burst containment and mechanical reinforcement
  • Cutting, finishing and assembly efficiency

Design for Manufacturability

Every proposed structure is reviewed for production feasibility, process control and future scalability. A design that performs well as a hand-made sample must also be capable of stable repeat production with measurable inspection criteria.

04

Custom Performance

Custom performance development begins with a clearly defined target and test method. Terms such as "high temperature," "heavy duty" or "flame retardant" are not sufficient by themselves; the required conditions and acceptance criteria must be agreed.

Performance Targets

PERFORMANCE AREA POSSIBLE TARGETS
Mechanical Abrasion, tensile strength, cut resistance, tear resistance, flexibility and burst containment
Thermal Continuous temperature, peak exposure, radiant heat, heat aging and dimensional stability
Flammability Specified flame test, smoke or transportation-industry requirement
Electrical Dielectric strength, insulation resistance, conductivity, grounding or shielding
Environmental UV, moisture, oils, fuels, coolants and chemical exposure
Installation Expansion, overlap, bend behavior, removal, access, cutting and assembly time
Identification Color coding, tracer yarn, labels, part numbers and traceability

Performance Development Method

1. Define the application conditions and critical failure risks.

2. Confirm the test method, sample conditioning and acceptance criteria.

3. Select candidate materials and product structures.

4. Prepare prototypes or comparison samples.

5. Conduct relevant internal or third-party testing.

6. Review results and optimize the design.

7. Approve the final specification and reference sample before mass production.

Product-Specific Validation

Certifications and test reports apply only to the relevant product, material, color, size and construction stated in the document. When accredited or specialized testing is required, MJ FLEX can coordinate with qualified third-party laboratories.

Developing Alternatives to Existing Products

MJ FLEX supports customers that need an alternative to a branded, expensive, discontinued or difficult-to-source cable protection product. Development may begin from a physical sample, drawing, datasheet, competitor part number or functional requirement.

What We Benchmark

  • Material and filament construction
  • Dimensions, wall thickness and product weight
  • Braiding, weaving, overlap or closure structure
  • Expansion, coverage, flexibility and installation behavior
  • Mechanical, thermal, electrical or environmental performance
  • Applicable certifications and documentation
  • Target cost, MOQ, lead time and supply stability

The objective is to reproduce the functions required by the application, not simply copy visual appearance. Any equivalence claim should be supported by agreed comparison criteria and appropriate validation.
