Connecting Your Innovation with Precision Manufacturing

At Jershin, we understand that a wire harness is the central nervous system of your device. If the signals don't flow efficiently, the entire system fails. This is why we have dedicated decades to perfecting the art of wire harness production.

We are not just a cable harness supplier; we are a strategic manufacturing partner. We work closely with OEMs (Original Equipment Manufacturers) to optimize designs for manufacturability, cost-efficiency, and longevity. Our facility is equipped to handle everything from simple, single-circuit ground wires to complex, multi-branch electrical harness systems containing hundreds of individual circuits.

By combining advanced automation with skilled manual assembly, recognized harness manufacturers like Jershin deliver the consistency required for high-volume production and the flexibility needed for custom prototypes.

Comprehensive Custom Wire Harness Manufacturing

Finding the right custom wire harness manufacturers can be a challenge. Off-the-shelf solutions rarely meet the specific geometric and electrical constraints of modern equipment. Jershin specializes in custom wire harness fabrication tailored exactly to your chassis and electrical specifications.

From Design to Mass Production

Our process begins with your schematic. Our engineering team reviews your CAD drawings and BOMs (Bill of Materials) to suggest the best components and routing strategies. This "Design for Manufacturing" (DFM) approach distinguishes us from other wire harness companies.

Component Sourcing: We source connectors, terminals, and wires from trusted global brands (like TE, Molex, JST) or high-quality equivalents to meet your budget.
Prototyping: We produce first-article samples for your validation before full-scale wire harness production begins.
Scalability: Whether you need 50 units for a pilot run or 50,000 units for mass market release, our production lines scale with you.

Types of Wire Harnesses We Produce

As versatile electrical harness manufacturers, we cater to a diverse range of needs:

Discrete Wire Harnesses: Simple point-to-point connections.
Complex Multi-Limb Harnesses: Systems with multiple breakouts for complex machinery.
Sealed & Waterproof Harnesses: Designed for harsh environments where moisture and dust resistance are critical.
Flat Ribbon Cable Harnesses: For space-constrained internal wiring.

Advanced Custom Cable Assembly Services

While wire harnesses organize individual wires, custom cable assembly involves grouping wires into a single protective sheath (jacket) to create a robust external connection. Jershin is a top-tier cable assembly manufacturer providing solutions that withstand external stress, abrasion, and interference.

Specialized Cable Solutions

Our custom cable assembly manufacturers team creates robust assemblies for external use. Unlike internal harnesses, these assembly cable products often need to look aesthetically pleasing and survive rough handling.

We produce:

Industrial Control Cables: High-flex cables for automation and robotics.
Sensor & Actuator Cables: Precision connectivity for data acquisition.
Power Cords & Battery Cables: High-amperage solutions capable of handling heavy power loads safely.
Data & Communication Cables: Custom lengths and pinouts for USB, Ethernet, and serial communications.

Overmolding and Strain Relief

A key differentiator in our custom electrical cable assemblies is our capability in overmolding. By molding connectors directly onto the cable, we provide superior strain relief. This prevents the cable from pulling out of the connector housing, significantly extending the lifespan of the product. This capability is why many clients choose us over other cable assembly companies.

Wire Harness vs. Cable Assembly: Understanding the Difference

For procurement managers, distinguishing between cable harness manufacturers and assembly providers is vital. Although the terms are often used interchangeably, there are distinct differences in manufacturing.

Feature	Wire Harness	Cable Assembly
Structure	Multiple individual wires bound by tape, ties, or sleeves.	Multiple wires encased in a single, durable outer sheath (jacket).
Primary Use	Internal use (inside a chassis or device).	External use (connecting device to device or device to power).
Environment	Protected inside the equipment; less need for heavy durability.	Exposed to the environment; requires resistance to heat, water, and abrasion.
Manufacturing Focus	Routing, breakout points, and organization.	Termination, potting, overmolding, and environmental sealing.

Jershin excels as both a wire harness manufacturer and a custom cable assembly provider, giving you a single source for all your connectivity needs.

Our Manufacturing Capabilities & Technology

To be a leading cable harness assembly provider, investment in technology is non-negotiable. Our manufacturing floor combines precision automation with expert craftsmanship.

State-of-the-Art Equipment

We utilize advanced machinery to ensure every assembly cable meets strict tolerances:

Automated Cutting & Stripping: Computer-controlled machines cut wires to exact lengths and strip insulation without damaging the conductor strands.
Automated Crimping: We use applicator-based crimping presses with Force Monitoring systems to ensure every crimp has the perfect mechanical and electrical bond.
Ultrasonic Welding: For splicing and joining wires without standard crimps, offering superior conductivity.

Capacity and Scalability

We are structured to handle high-mix/low-volume orders (typical of industrial and medical sectors) just as efficiently as low-mix/high-volume automotive orders. Our custom cable harness production lines are modular, allowing us to reconfigure quickly for different project requirements.

Industry Insight: According to IPC Standards, proper crimping and soldering techniques are the primary factors in preventing electrical failure. Jershin adheres strictly to IPC/WHMA-A-620 standards.

Uncompromising Quality Assurance

In the world of electrical harness manufacturers, quality is not just a buzzword—it is a safety requirement. A single faulty connection in a vehicle or medical device can have catastrophic consequences.

Our Quality Assurance (QA) protocol includes:

Incoming Material Inspection (IQC): Verifying all wires, terminals, and connectors match specifications.
In-Process Quality Control (IPQC): Pull-force testing on crimps and visual inspections during assembly.
100% Electrical Testing: Every single custom wire harness assembly is tested for continuity, shorts, and mis-wiring before it leaves our factory.
