A wiring harness is an organized assembly of wires, cables, terminals, connectors, and protective materials designed to transmit electrical power, signals, or data between components in a vehicle, machine, or electronic system.
Modern automotive wire harnesses are becoming increasingly complex. The rapid growth of electric vehicles (EVs), ADAS, high-voltage systems, CAN bus, and Automotive Ethernet has significantly raised the technical requirements for wire harness design and manufacturing.
China is one of the world’s leading custom cable assembly manufacturing centers, supported by a complete supply chain covering cables, connectors, terminals, injection molding, assembly, and testing. International OEM buyers choose Chinese suppliers not only for cost advantages, but also for customization capability, engineering support, flexible production, and fast product development.
International buyers choose Chinese suppliers not only for competitive pricing, but also for customization, rapid prototyping, engineering support, and scalable production. However, sourcing risks can include trading companies, unstable crimp quality, incomplete testing, material substitution, delivery delays, and weak traceability.
Ethernet and RJ45 cables are still one of the most reliable connection solutions for industrial equipment, data centers, security systems, robotics, medical devices, and smart home products. Compared with wireless connections, wired Ethernet offers more stable transmission, lower latency, better security, and stronger resistance to complex working environments.
This guide compares 15 LVDS cable assembly manufacturers worldwide and explains how OEM buyers should evaluate suppliers from an engineering and manufacturing perspective. Instead of only listing company names, we will look at what each type of supplier is best suited for, what technical capabilities you should check, and what questions you should ask before choosing a long-term LVDS cable assembly partner.
Heat shrink tubing is a polymer tube that shrinks in diameter when heated to a specified recovery temperature. I usually explain it to customers as a protective sleeve that starts in an expanded form, slides easily over a wire, splice, terminal, or branch point, and then contracts tightly around that area when heat is applied. This shrinking action creates a close-fitting layer that improves insulation, mechanical protection, and overall harness durability.

Before we dive into choosing the right material like PVC, TPE, or TPU for your overmolded cable assembly, it’s important to understand what overmolding is and why it’s a critical part of cable design. Overmolding isn’t just for appearance.
Understanding what the application truly needs makes it much easier to judge whether a supplier can deliver the right jumper wires. Without this foundation, even the best supplier answers may not help you make the right choice. That’s why I always begin by clarifying the electrical, mechanical, and environmental demands of the project before evaluating any supplier.
