Choosing the correct cable requires careful consideration, whether molded or Assembled VS Molded Cable Assembly; insulation, conductors, and sheathing are different areas you must visit.
All these choices make or mar the performance and durability of your finished cable. Even the best-sheathed cables cannot prevent damage at the final point. After fitting a connector, that section of the cable will likely bend and twist more than you bargained for. Thus, for the cable’s success, a connector shell is critical.
Here, we’ll differentiate between two custom shells: Assembled and Molded.

Chapter 1: Assembled VS Molded Cable Assembly–Assembled Cable
As the name suggests, assembled cables include many pieces that are manually assembled at the field. In some applications, plastic or metal connectors are the only alternatives. These are custom-made assemblies that assure easy installation. Metals or plastic are the widely used materials for assembled cables.
Three essential factors when opting for an assembled cable are the labor, its cost, and future repairs.
Assembled VS Molded Cable Assembly–Proper Installation
Assembling cables on the field demands experienced and knowledgeable technicians. To avoid installation failure, ensure the in-house or outsourced personnel test the cables at every step.
Production of assembled cables may save you a few bucks, but the labor costs add to the total. The sum brings you to close to the cost of molded cables.
Assembled VS Molded Cable Assembly–Maintenance
Assembled cables offer quick and easy fixes or modifications. Since they are built using multiple components, if the assembly requires any repairs, replace one component.
Assembled cables serve a purpose similar to wire harnesses, and the terms are often used interchangeably. But they’re designed for diverse applications.
Cable assemblies protect the interior wires and cables from several environmental hazards. The threats can be anything from moisture to heat. Contrary to molded cable assemblies, this variant offers flexibility.
The next chapter includes everything you need to know about picking the perfect molded cable for your equipment.
Chapter 2: Assembled VS Molded Cable Assembly–Molded Cable
The second type of cable assemblies, the custom-molded cable contains a Polyvinyl Chloride (PVC) shell. The process of molding cables is such:
The cables enter a wire cavity with the connectors attached to them.
The mold is then injected with thermoplastic PVC and heated.
The result is a finished cable once you remove the PVC after it has cooled down.
The method remains constant, but instead of exposed terminals, you get a PVC encapsulated connector. You cannot separate the components now; the coating makes the cables solid and durable, not leaving room for alterations. Thanks to the durable coating, they last longer and even in the most extreme conditions.
Molded cable assemblies or Overmolded cable assemblies are custom-made and eye-catchy. Although a vibrant appearance isn’t what customers look for when creating cable assemblies, they must. The vivid colors help to assess the cables after installation in case a cable needs switching or replacement.
Over the last decade, Overmolding has drastically changed the appearance and functionality of cable assemblies. Molded cable connectors extend the life of your product and diminish installation errors.
If quality is your concern, Overmolding gives you premium results. It helps to enhance the performance and durability of the assembly. Materials utilized can depend on electrical, mechanical, and physical requirements. Choose proper compounds from a wide range of choices, including:
- Polyvinyl Chloride (PVC)
- Polypropylene (PP)
- Polyethylene (PE)
- Thermoplastic Polyurethane (TPU)
For harsher environments, a molded cable assembly may be the best option. Overmolding offers strain relief at the exit points rather than leaving them unbounded. The process is adequate for cable breakouts or Y/J Junctions. This kind of assembly connector also works as an anchor point called cable stops. Extra protection to the exposed joints of the cable assembly in the form of seals and glands offers endurance.

Now, let’s move onto the next section of Assembled VS Molded Cable Assembly–The Guide to Choose the Right Type. It covers the key differences between assembled and molded cables.
Chapter 3: The Difference Between Assembled VS Molded Cable Assembly
For both cable, there are many people confused. So, to avoid the mix-up, we’ll help you perceive the two cabling assemblies by distinguishing between them.
Difference between Assembled and Molded Cabling Assemblies
These are all the basic factors to differentiate between the two cabling assemblies. Both the assemblies serve a specific purpose and are reliable for certain projects. Let’s discuss their pros and cons in the following segments.
For Assembled cables, three features are essential to measuring the credibility; cost, installation, and repairs. The set comes with both advantages and disadvantages.
Assembled Cable Advantages:
Their flexibility plays as a major plus point for the assembled cable assemblies. Other than elasticity, the cabling methodology boasts several advantages; these are some of them:
Cost– Assembled cables are less expensive to produce. Additionally, you may save a few bucks in the long run if any piece needs replacement.
Installation– Their heterogeneous nature makes the installation process hassle-free. Experienced technicians perform the process leaving very little room for error.
Repairs– The requirements of every project are different. Designing assembled cables to suit the user’s specifications prevents elongation of cables and their bending.
Assembled VS Molded Cable Assembly–Assembled Cable Disadvantages:
Complex on-field installation sometimes becomes chaotic without experience and knowledge. To top it off the factors influence a few disadvantages:
Cost– Technicians often overlook the labor costs creating a mess during the final tally.
Installation– Improper installation may lead to performance failure humans are prone to errors.
Repairs– In case of any malfunctioning port, it becomes impossible to locate the source behind it.
Moving on to the molded cables, they come with many advantages along with a few disadvantages.
Molded Cable Advantages:
We already know that molded cables cost you more than assembled cables. Their high rate is mainly because of two reasons: customization and strength.
Installation– Since there’s no complex assembly required, there is no chance of making mistakes in the installation process. Also, the aesthetic appeal of the cables allows technicians to make easy and quick connections.
Quality– Molded cables made of high-quality compounds ensure the best cable assemblies without constant wear and tear.
Durability– Custom molds and mixtures elevate the opportunity for a durable end product.
Assembled VS Molded Cable Assembly–Molded Cable Disadvantages:
The cost of producing the mold alone costs the manufacturer’s a fortune. Imposing it on the customers becomes mandatory to avoid loss. There are certain cons associated with appealing and durable Overmolded cables, they are:
Installation– Use of multi-colored cables may lead to confusion if not marked properly.
Quality– Through the molded cables offer premium quality, some manufacturers experiment with the quality. The consequence is low quality, accident-prone connection.
Durability– Strong wires leave no room for flexibility. You cannot bend and twist these wires into custom-spaces. Getting the right sized mold causes stiffness.
In all, both the assembling strategies are spot-on with some minor shortcomings. Depending on your requirements and environmental conditions determine the correct type.
Chapter 4: How to Choose the Right Connector–Assembled VS Molded Cable Assembly?
We’ve gone through the variances and vices and virtues of the different assembly types. In this part, we’ll focus on a mutual issue faced by the public working on technical projects. Choosing the right connector, it is quite challenging. But with the correct approach, they can tackle this problem seamlessly.
Two aspects, however, get an edge over others and they are cost and the situation in which the cables need assembling.
In most cases, connectors are the cheapest commodities that projects demand. Buying the lowest-priced item isn’t the solution; it only gives rise to future problems. Compare costs and stipulations for your project and decide.
For assembled cables, especially, environmental aspects turn into challenges. Extremities such as air pressure, moisture, and extreme temperatures threaten most ventures.
Based on your setting and budget, you can select from a variety of connectors for your project. Confusion is natural while selecting the appropriate connector that meets your requirements. The following video takes you through the basic connectors for computers, but they are valid for different scenarios.
For this reason, technicians opt to customize products with the assistance of professional manufacturers.
