our recommendation of
Custom Wire Harness Materials
Normally, many customers already have wire harness designs, but some customers initially only have an idea. This is when they need us the most, because they are unclear about the selection of connectors and cables. These types of customers don’t have specific requirements for the appearance of the connectors. This is when QL-Custom truly takes control of custom wire harness applications and adds value. We are happy to help customers solve these types of problems.

Custom Wire Harness Solution Service
Simply put, custom wire harness solutions meet all your wiring harness needs. Some suppliers don’t provide certain services, leaving customers to provide those. If everything is provided by the customer, what do we do? If we can't meet the customer's wire needs, what value do we add? How long can a supplier that doesn’t consider custom requirements survive? Therefore, you can rest assured when handing over your requirements to us. Your project is our project.
Twisted Wire Harness
Twisted wires help improve signal shielding, but some suppliers don't handle the twisting pitch correctly. For example, some customers request 2 turns per inch of twisting, but the supplier only gives 1.5 turns. This is often because they don't have enough wire length, cutting corners to save material.
Wire Harness Splices
There are three types of wire splicing: the most traditional is soldering and using wire terminals. We use ultrasonic welding, which completely eliminates issues like tensile force and current overload.
Wire Harness Cover Protector
Braided sleeving and convoluted tubing protection are the most common ways to protect wire harnesses. If you just need neatness, a tie wrap will suffice. But if it's for agricultural vehicle wiring, Yarn Braiding becomes the preferred choice.
Wire Harness Testing
Many wire harness suppliers still perform 100% continuity testing, but we also add a pin position test to ensure that terminals are in the correct position. Additionally, for automotive wire harnesses, we also conduct air-tightness testing.
Wire Harness Crimping Terminals Pull Force
Have you encountered a situation where large wires are crimped with small terminals? Our wire harness manufacturing experience often shines in these details. We have our methods to solve these problems.
Restricted Space Applications
What happens when our customers need to use wire harnesses in tight spaces? The choice of connectors is crucial. Micro and miniature connectors play a key role here. For example, for DB9 connectors, our recommendations are different.

Custom Overmolded Cable Assemblies
When obtaining overmolded cable assembly quotes, have you often received mold quotes costing hundreds or even thousands of dollars? This is because the product hasn’t been made before. At QL-Custom, we have thousands of molds, which allows us to save costs wherever possible. Of course, if your requirements are special, we can also provide quotes in the shortest time.
Custom Tooling Service
From simple to complex molds, from PVC, TPE to high-temperature plastics, you can contact us to get the best and fastest quotes and solutions. We assist you in completing your project evaluation and implementation.
Special Purpose Plastic Overmolded Cables
When you have special requirements using TPE, TPU, or Nylon molding, you will notice that their molding temperatures and adhesion between the molded body and material are different. QL-Custom has fully mastered these molding techniques, including the temperature of the molding machines and the injection pressure adjustments.
Overmolded Hood Durability
When designing plug fixed positions, some customers may opt for panel mount requirements. Panel mounting needs to ensure whether the screws are external or internal locking, and determine the screw hole spacing and connector exposed length to avoid narrow terminal contact surfaces, which could increase current or signal impedance.
Overall Cable Part Overmolding Solutions
Full encapsulation of the wires means that all wires between connectors are fully overmolded. Based on molding principles, the longest molding length can be 130-140mm, and anything longer could result in poor molding. This solution is suitable for short-distance FPC flat wires, as well as medical or adult product designs.
IP Rated Waterproof Overmolded Cable Harness Solutions
Custom cable harnesses with waterproof ratings require a concept of waterproofing in the overall product design. IP67, IP68, or even IP69 designs must use male and female connectors together, not just male connectors or female connectors. Or connectors to boards. The design must ensure a waterproof seal between solid hardware components when the male and female connectors are inserted or when connectors are mounted on boards. If just two pieces of hardware connect directly, complete waterproofing cannot be achieved.
