When talking about mold cables, we should also know the fundamental structure of the molded lines. The molded cable structure is a structural and straightforward method that creates the cable industry’s needed systems. Usually, rigid shield connectors are introduced within a cable system to maintain a high level of continuity.
This article will present the ultimate guide to mold cables, focusing on over-molded lines, advantages, applications, and misconceptions.
Mold Cables–What is Overmolding？
Overmolding is a process used to combine at least two materials into one object. When it comes to the molding of cables, materials to be converted are carefully selected. This selection must meet the requirements for transferring the required data safely, and it is also carefully checked to meet the stress demand of external environments.
1.1 The Process of Injection Molding
This molding is a very distinct process done sensitively. To every molding, there are two major concepts to be known. These are:
The Overmolding material.
In the process of injection molding, the substrate part gets molded first. Next, you should follow one of the following two steps to combine it with the over-molding material:
It would help if you used a different mold to combine the molded substrate with the over-molding material.
The part was placed into the mold, and then the over-molding material was added to it.
You can achieve this process after cooling the mold down and removing the material from the mold.
1.2 The Process of Insert Molding
Insert molding is also another susceptible process. Unlike the injection process of molding, both the substrate and the molding materials heat simultaneously. During the substrate molding, the molding material is added to it directly.
Overmolding Cable Material Selection
Thermal bonding is the critical factor in selecting the best cable over-molding material. The question here is, “What is thermal bonding?”
You can achieve thermal bonding due to the application of heat in the process of molding the materials. The strength of the over-mold depends on the method of heat application.
Some of the over-mold materials commonly used include:
Design Considerations of Overmolding
It would help if you carried out design considerations for over-molding with the provision of durability and flexibility in mind. Due to this, the production material is carefully and specifically selected to meet the requirements. Before designing, the molding material’s type and texture, understanding the substrate and the production parameters are necessary. These considerations help avoid the production of sub-standard cables for consumer consumption.

The Materials of Cable Overmold Tooling
An injection process is one of the most commonly used processes in industries to mold cables, and it consists of a specific machine that easily carries out these processes.
Molds typically consist of various metals. The choice of metal depends on the quality of the expected product. Steel is the most reputable material for mold production. Nevertheless, it is one of the most expensive metals.
The Overmolding Process of Cable Assembly
Overmolding is a compassionate act, and you can achieve this by forcing material into a mold cavity under high pressure.
The critical steps in the over-molding process of the cable assembly are:
- Determine the best combination of substrates to achieve the best adhesion between the substrate and the over-molding material.
- Designing of the appropriate mold and over-mold tools
- Maintaining the melting temperature of the substrate is also critical. This activity helps determine how easily the substrate flow during the molding process.
Another thing to be cautious of during the substrate’s melting process is its surface. The surface must be immaculate, clear, and free of contamination. You must eliminate dust particles, foreign substances, excessive moisture, and skin oil.
The working environment must be checked to know the humidity level for the process. Also, the use of gloves when handling anything during this process is highly advisable.
NOTE: – The slight contamination of the substrate could weaken the bond strength between the substrate and the over-molding substance. This weakness is because the moisture content of both substrate and over-molding material negatively affects bonding strength. Therefore, you must dry both the substrate and the over-molding material before molding.
Designs of Overmold and Pre-Mold
The pre-mold and the over-mold are two different parts. Their explanations are as follows:
Just as the name implies, it means “before molding” with the prefix “pre = before.” This design is an initial molded design of a cable before over-molding, and it might consist of fasteners and screws to hold components together.
This prototype has a design that reduces the use of fasteners and screws to hold components together. When done correctly with a suitable substrate, the molding process can confer strong bonding to materials.
Overmolding VS Two-Shot Molding
The over-molding is different from two-shot molding, and this difference is because the cables drawn from the over-molding are more durable.
Wires drawn from over-molding can withstand harsh conditions. The two-shot injector needs a specific injector tool.
Single or Multiple Cavity Molds Designs
The multi-cavity mold designs are for large-scale and general industries.
In contrast, the single mold design works just for a single small production.
The Finished Product Appearance
The molding process is perfect. However, some of the substrate’s little solidification coming through the finished products’ mold causes challenges. Sometimes, some machines might touch the surface, thereby creating a mark on the cable. These marks are typically unique to the product and hard to prevent. The only preventive measure to be taken is making tight dimensions of tolerance when designing molding tools.
The Applications of Over-molded Cables
What we all call over-molding has its applications in the generation and storing of solar energy. It has found use in military service due to the harsh conditions of their environments. Also, it is a good cable design for consumer electronics.
In medicine today, the best cables used to run most equipment are all over-molded. It fits the harshest working conditions, such as heat and extreme cold, when it comes to industrial applications.
The fundamental importance of over-molding cables is to improve the aesthetics of the products. Most of the merits of these cables are in:
- Providing a succulent grip around the cables of choice for easy use
- Manufacturing sealed cable products.
- Eliminating the need to assemble multiple parts
- Eliminate the need to use fasteners during assembly.
Mold Cables: All You Need to Know
The Typical Uses of Mold Cables
For Medical Appliances
The use of customized cables in medical instruments is of high importance, and these cables have proven to stand resistant against UV rays and corrosive solvents.
In medical appliances, cables get used for their longevity and durability. Instead of getting an entirely new line, molding the subsequent ones will be more cost-effective.
Military gadgets use these over-molded cables due to the harsh environments they get exposed to during use. The over-molding confers longevity and durability to these cables, and the lines proved to be reliable.
(Cables for Military Appliances)
Valuable for Electricity Transmission
The purpose of over-molding wires for electric transmission is to avoid loss of current. Most of the over-molding materials are segmented within to prevent the loss of wind, and this loss of current exists in the form of “day Current.”
Molding cables for this purpose offer longevity and durability in the harshest conditions.
Home and Office Appliances
These cables are also over-molded for better use at home and offices. The molding process ensures the safe transmission of data for TVs and antennas, and personal computers. They have found use in printers, photocopiers, scanners, smartphones, microwaves, refrigerators, and many other appliances.

Mold Cables– The Process of Cable Assembly Molding.
The molded cable assembly can confer significant advantages through the prototype design. A group with durability and a fine finish outlook is what a consumer will often choose. The process includes the operator, the machines (tools), the equipment, and the production process.
The operator is an individual who oversees the mmachine’sfunction in both automated and manual manufacturing machines. This individual is more like the component of the device. Without the operator, the engines would cease to work.
In the cable assembly industry, the operator is essential. The things the operator must do are as follows:
- Know the basics of operation of the machines and tools under his care.
- Pay close attention to production variables to avoid production error.
- The operator must wear safety protective equipment at all times during production.
This phenomenon refers to assessing the operator in the manufacturing site. The assessment is to ensure the individual correctly matches the requirements.
Training in machine mechanics
The operator needs to know a lot more than just production, and he must also see how the molding machine operates.
During this IT training, the operator must understand the mmachine’stechnical parts and its working principles.
An ooperator’smajor qualities are to detect possible potential threats and devise a solution for better production.
It includes keeping the cables away from where they can be damaged to avoid electric shock accidents. This management is more of a reason why molded cables get preferred in firms and industries.
During manufacturing, the appearance of the final products is essential to the marketing of these products. A ddesigner’swork is to determine the cavity method that is best for the nature of production. Cavity methods could be single or multi-cavity.
We should know that an experienced tool designer has the capabilities to design elements that fit. These elements must also allow for the various efficient ejection of the finished part, and they will go a long way in determining the finished pproduct’sappearance.
In any industry, a proper equipment management system is an essential aspect of successful production. The act of doing proper Preventive maintenance is necessary to ensure molding machines. Having a new production line can also reduce the depreciation rate of the devices.
Unlike the conventional molding technique, insert molding provides the best environment with fewer process challenges. It is common for an operator to take a break during production. With each of the processes of production, the condition required is specific for each product.
4 Ways to Shield Over-molded Connectors for Custom Cable Assembly
Shield Over-molded connectors for custom cable assembly are essential in the transmission of data and information. The custom cable assemblies are susceptible to electromagnetic force and Radio Frequency Interference.
There are technically four different ways to shield over-molded connectors for custom cable assembly:
Mold Cables–Foil Shielding
It is the most suitable way of covering the cconnectors’outer surface for custom cable assemblies. There is a provision of flexibility and durability for the cable assemblies.
Mold Cables–Braided Shielding
This shield is a covering that protects your cables from EMF and RFI. Braided shielding is one of the oldest and largest methods used for shielding connectors.
NOTE: – The strength of the braided shielding for the over-molded connector for custom cable assembly is second to none.
Mold Cables–The Combination of Foil and Braided Shielding
This type of shielding braid has the features of both the foil shielding and the braided shielding simultaneously.
It combines the characteristics of both types to enhance their longevity, durability, and functionality.
Mold Cables–Spiral Shielding
This type is yet another shielding method that covers the over-molded connectors of the custom cable assemblies. It has high flexibility and durability. Besides, it is highly compatible with the device of choice.
Tips To Know About Molded Cables Connectors
- Custom cable connectors comprise different parts. The parts include
- The actual wire
- A jacketing portion to shield the wire and
- Insulators or conductors.
It seems straightforward when said than produced. However, it is pretty confusing considering the different types of cable systems. Of the different types of cables existing on the market today, molded lines remain popular, and all of these cables differ based on their durability and functionality.
Mold Cables–Assembled VS Molded Cables–What You Need to Know
The Assembled Cable
Assembled cables are the pre-mold cables. They are also known as off-shield cables.
Mold Cables–Molded Cable
These are the over-mold cables that have undergone shielding with some other substrate.
Mold Cables–The Difference Between Assembled and Molded Cable
Unlike the molded cables, the assembled lines consist of fasteners to hold parts together.
The molded cables are more durable and can withstand the effects of harsh environments than the assembled cables.
Mold Cables–The Connectors of Molded Cable are Highly Customizable
Materials used for molding cables. They occur in different colors once the material melts.
We should know that the over-molding material can enhance mechanical and physical properties, just like the substrate.
They usually have high resistance to external factors.
Mold Cables–The Cable Environment is Extremely Important
It would help if you considered the environment that the cable will expose. Some settings have harsh thermal conditions, and these environments require unique materials for cable manufacture.
Mold Cables–Molds Can Be Expensive to Produce
There is an issue with the cost of manufacturing molds, and this issue typically exists only at the time of the first production. Once there is an assembly of production, the cost of production will reduce drastically.
Mold Cables–3D Printing Can Be Rapidly Prototyped and Tested
The advent of 3D printing opens a new phase for the molding process. We are heading into the artificial super intelligent state of technology, and this phase is where most things are mechanized for a more accurate product.
Mold Cables–Molded Cables Result in the Higher Quality Products
The mold covers the cables and confers the shielding effect from EMF and RFI effects.
9 Benefits to Using Custom Molded Cables Assemblies
Prototype tests Reduce Chances of Error
The pre-mold mmold’sdesign and prototype and the post-mold / over-molded cable impact the final pproduct’squality. The chances of making errors during production are very slim, as most of the process is automated.
Mold Cables–Cost Savings
Custom molded cables are highly cost-effective, and this cost-effectiveness is a result of the production scheme used during manufacturing. Removing some of the normal off-shell ccables’elements is essential, and it creates a better bonding of the over-mold material and the substrate. In the long run, it also reduces the cost of production, thereby reducing the overall selling price.

8 Myths and Misconceptions about Custom Overmolded Cable
Mold Cables–Custom Overmolded Cables Take Too Long To Manufacture
The above statement no longer holds for the manufacturing of custom cables. We are at a technological age, and production firms have adopted assembly line production. This production is where a specific section produces every part, thereby making the work faster and easier.
Mold Cables–Custom Cables Are More Expensive
The above statement was true before the advent of the new technologies used in the over-molding process. Due to more unique molding processes, and they are also one of the most economical types of threads you will get in an electronic store.
Custom Cable Connectors Are Not High PriorityCustom cables are a high priority, continuously increasing demand.
Mold Cables–Can Only Provide IP67 With Limited Materials
This statement is another misconception relating to over-molded cables, and people believe that over-molded lines can only provide waterproofing with unique materials. Nevertheless, if you want cables that can provide a waterproofing attribute, you should first contact the manufacturer, and we can help you with that.
Mold Cables–Off the Shelf, Cables Have the Same Quality as Custom Cables
Different cables have different properties and qualities. A common misconception with most users is that all wires have the same rate, and this assumption is very wrong. Custom cables tend to be more durable than regular off-shell cables.
Mold Cables–Overmolded Cables Are Not As Flexible As Others
Many users are quick to assume that over-molded cables are not flexible. This assumption is wrong because a custom ccable’sflexibility depends on the ssubstrate’sconstituent and the over-molding material. Overmolded wires are just as loose as other materials.
Mold Cables–Overmolded Cables Do Not Provide in-depth customization.
This assumption is also very wrong. The only available customized cables with in-depth customization are the over-molded cables.
Mold Cables–Custom Cables Have Much Larger Minimum Order Quantities
When talking about demand, it is pronounced that the demand for custom cables is very high. This high demand results from the emergence of new devices, and it is also due to the need to transfer data from older devices to new devices.
You now know that using over-molded cables reduces the costs of making and purchasing a product, and it also creates awareness in you that you can use a line more efficiently with durability.
