When I look at a wire and cable extrusion project, I do not start by asking how many machines are in the Production Line. I start with the finished wire. What material will be used? What type of insulation is required? What is the cable structure? What size range needs to be produced? How stable does the Production Process need to be?

These questions are especially important when choosing a 60+35 Insulation Extrusion Production Line. A dual-extruder configuration is not simply about putting two extruders together. The two extrusion units, material feeding system, forming section, cooling section, traction system, take-up equipment, and electrical controls all need to work as one coordinated production system.

At Wuxi Shuochuan Electromechanical Equipment Manufacturing Co., Ltd., I work with this practical idea in mind. We develop and manufacture extrusion equipment for wire and Cable Production, including photovoltaic wire and Cable Production Lines, automotive Wire Production lines, electronic Wire Production Lines, network communication wire production lines, charging pile cable production lines, and other extrusion-related equipment.

Our 60+35 Insulation Extrusion Production Line is designed for continuous and stable insulation extrusion. Depending on the actual cable structure and production requirements, the line can be configured to support controlled material feeding, continuous extrusion, insulation forming, cooling, traction, take-up, and automated operation.

I also understand that a cable factory does not need a machine that looks impressive on paper but becomes difficult to operate on the shop floor. What matters is whether the equipment matches the product, whether operators can understand the process, whether maintenance is practical, and whether the complete line can run steadily over time.

1. What Is a 60+35 Insulation Extrusion Production Line?

The 60+35 Insulation Extrusion Production Line is a wire and cable extrusion system built around 60-class and 35-class extrusion units. The exact technical meaning of the model designation should be confirmed according to the final equipment configuration and customer requirements.

In practical production, a line like this can be used when a cable structure requires coordinated extrusion processes or when different material layers need to be processed within one production arrangement. The actual application depends on the product design and process route.

The key point is that the two extrusion units should not be viewed as completely independent machines. Their working relationship needs to be considered together with material feeding, extrusion dies, cable forming, cooling, traction, take-up, and control.

A typical 60+35 Insulation Extrusion Line may contain the following functional sections:

• Material feeding and preparation equipment

• 60-class extrusion unit

• 35-class extrusion unit

• Heating and temperature control system

• Extrusion die and forming components

• Cooling and sizing section

• Traction or haul-off system

• Take-up equipment

• Electrical control cabinet and control system

• Necessary Auxiliary Equipment

The final configuration is not fixed for every customer. For example, a factory producing a specific electronic wire may have different requirements from a manufacturer producing automotive wire or charging cables.

Source: Wuxi Shuochuan product and engineering information supplied for this product page. Actual line configuration depends on the customer's product and process requirements.

For this reason, I prefer to describe the 60+35 system as a complete production solution rather than simply calling it a 60+35 extrusion machine. The complete line determines how the material enters, how the insulation is formed, how the cable is cooled and pulled, and how the finished product is collected.

2. How Does the 60+35 Insulation Extrusion Line Work?

The basic extrusion principle is easy to understand. Plastic or other suitable insulation material is supplied into the extrusion unit. The material is heated and processed inside the barrel while the screw moves it forward. The processed material is then pushed through an extrusion die to form the required insulation layer around the conductor or cable structure.

With a 60+35 extrusion production line, the two extrusion units can be arranged according to the intended production process. The exact arrangement depends on the product structure and material requirements. This is why I do not recommend assuming that every 60+35 line should use exactly the same process settings.

Material Preparation

The process begins with the insulation materials. Before production, I recommend confirming the material type, grade, processing requirements, storage condition, and any drying requirements. Some materials require careful moisture management, while others have different temperature and processing characteristics.

Good material preparation is easy to overlook. However, unstable material conditions can create problems later in the extrusion process. The extrusion machine cannot completely compensate for poor raw material handling.

Material Feeding

After preparation, the material is supplied to the extrusion units. Stable feeding is important because the extruder needs a consistent supply to maintain a steady process.

For a production line using two extrusion units, material feeding also needs to match the planned process. If two materials are involved, each material must be correctly assigned to the relevant extrusion unit and forming stage.

Plasticizing and Extrusion

Inside each extruder, the screw transports the material through the heated barrel. The material gradually becomes suitable for extrusion and is pushed toward the die.

This stage involves several technical factors, including temperature control, screw movement, material behavior, pressure, and residence time. I normally recommend setting the actual process according to the material supplier's technical information and the customer's cable requirements rather than copying settings from another product.

Insulation Forming

The extrusion die is where the processed material takes its final basic shape around the wire or cable. Proper die selection and alignment are important for stable insulation coverage.

The conductor or cable core must also move through the forming area in a controlled way. If the cable position changes too much, the insulation layer may become uneven. This is one reason why extrusion, traction, and cable alignment need to be considered together.

Cooling and Sizing

After the insulation material leaves the die, it needs to be cooled and stabilized. Cooling allows the newly formed insulation layer to become more stable as the cable continues through the line.

The cooling arrangement depends on the material, product size, production process, and line configuration. It is not sensible to use one cooling setup for every cable product.

Traction and Take-Up

The traction system moves the cable through the production line. The take-up equipment then collects the finished product.

For continuous wire and cable production, the relationship between extrusion and traction is especially important. If the cable is pulled too aggressively or the process is not coordinated properly, product dimensions and insulation quality can be affected.

3. Main Features of the 60+35 Insulation Extrusion Production Line

When I design or evaluate an extrusion production line, I look for practical features that make a difference during everyday manufacturing. A good production line should not only complete the extrusion process. It should also be manageable, maintainable, and suitable for the factory environment.

Dual Extrusion Configuration

The most obvious feature of the 60+35 Insulation Extrusion Production Line is its combination of 60-class and 35-class extrusion units. This gives the production system a coordinated dual-extrusion structure for applications where the product process calls for it.

The actual material assignment and process arrangement should be determined according to the product. I do not treat “60+35” as a universal process formula. Instead, I use it as the equipment basis for discussing the required production configuration.

Continuous Production

Wire and cable manufacturing often involves long continuous production runs. Stopping the line repeatedly can make the production process less convenient and may increase material waste during startup and adjustment.

Our line is designed around continuous production, with the extrusion, cooling, traction, and take-up sections working together as one process.

Controlled Extrusion

Stable extrusion depends on consistent material feeding and controlled processing. The extrusion units are designed to provide a controlled material flow suitable for the selected application.

I always stress that equipment capability and process capability are not exactly the same thing. Even a well-built extruder needs the correct material, die, settings, and operating procedure to produce a stable finished product.

Practical Automated Operation

Automation is useful when it solves a real production problem. Our equipment is developed with practical automated operation in mind. The control system can coordinate the different sections of the line and make normal production easier for operators.

Flexible Product Applications

The line can be considered for different wire and cable applications depending on the required insulation process. These may include electronic wires, automotive wires, photovoltaic cables, communication cables, charging cables, and other extrusion-related products.

Integration With Supporting Equipment

A complete extrusion process usually requires more than the main extruder. Feeding equipment, cooling equipment, traction, take-up, unwinding, control systems, and other auxiliary components can all affect the production workflow.

Because Wuxi Shuochuan also manufactures different take-up and unwinding series and auxiliary equipment, we can consider the line as part of a broader production system.

4. Technical Advantages and How I Recommend Selecting the Line

If you are comparing different 60+35 insulation extrusion machines, I suggest looking beyond the machine model. In real production, the “best” configuration is the one that fits your product and factory.

Start With the Cable Structure

First, tell me what you are producing. A single-core wire, multi-core cable, communication cable, automotive wire, or photovoltaic cable can have very different structures.

The cable structure affects the extrusion die, insulation process, cooling arrangement, traction method, and take-up requirements.

Confirm the Insulation Material

Material selection is equally important. PVC, PE, XLPE, silicone rubber, nylon, and other materials do not behave in exactly the same way during extrusion.

For this reason, the 60+35 insulation extrusion equipment should be selected together with the actual material requirements. If a customer already has the material datasheet, I recommend sharing it during the technical discussion.

Understand the Product Size Range

Product dimensions are another important consideration. If a factory plans to produce several wire and cable sizes, we need to understand the range before finalizing the equipment arrangement.

Consider Production Capacity

Capacity should be discussed in relation to product size, material, process, and production schedule. I avoid giving a generic output number without knowing what product is being produced because such a number can be misleading.

Think About the Factory Layout

A production line needs physical space. Operators need access to the machine, maintenance personnel need room to work, and the cable needs a practical path through the line.

Before manufacturing, I recommend checking the workshop layout, available installation space, material flow, cable direction, electrical supply, and operator working area.

Check Future Production Plans

If the customer plans to add new cable products later, this should be considered before the machine is built. A small amount of planning at the beginning may save considerable modification work later.

This is also why I encourage customers to provide drawings, product specifications, material information, or samples when possible. The more clearly we understand the product, the more confidently we can discuss the equipment.

5. Applications in Wire and Cable Manufacturing

The 60+35 Insulation Extrusion Production Line can be applied to different wire and cable manufacturing processes where its dual-extrusion configuration is suitable for the product design.

Automotive Wire Production

Automotive wires require consistent insulation and reliable production control. A properly configured extrusion line can support continuous processing for suitable automotive wire products.

When working with automotive wire manufacturers, I would first confirm the conductor structure, insulation material, finished dimensions, product tolerance, and production requirements. These details determine how the extrusion process should be arranged.

Electronic Wire Production

Electronic wires often have compact structures and specific dimensional requirements. Stable extrusion and accurate forming can help manufacturers maintain consistent product quality during continuous production.

The actual die and process setup should be matched to the wire size and insulation material rather than simply copied from another electronic wire line.

Photovoltaic Cable Production

Photovoltaic wire and cable is another area covered by our company's production equipment range. These cables are used in solar power systems and have their own material and construction requirements.

For a photovoltaic cable project, I recommend confirming the applicable cable standard, material system, product structure, and production process before choosing the final extrusion configuration.

Network Communication Cable

Communication cable production requires attention to product structure and dimensional consistency. Depending on the cable design, extrusion may form insulation or other protective layers.

The production line should be matched to the complete cable structure, not just the outer diameter.

Charging Pile Cable

Charging pile cables are another important cable application in our product range. The cable structure and material requirements can vary according to the intended use.

For these products, I recommend reviewing the complete cable construction before deciding whether the 60+35 configuration is suitable.

Other Extrusion Products

Our extrusion equipment is also used in other extrusion-related industries, including silicone rubber products and different industrial cable applications. The suitability of a specific production line depends on the material and process requirements.

6. How We Manufacture and Test the 60+35 Extrusion Production Line

Manufacturing an extrusion production line is a process that starts with technical communication. I do not think it is practical to build the equipment first and ask detailed product questions afterward.

Step 1: Customer Requirement Review

Before production, we confirm the product specifications, material requirements, production capacity, equipment configuration, and delivery schedule with the customer.

This stage creates the technical foundation for the project. If the customer has product drawings, cable samples, material datasheets, or process requirements, these can help us understand the application more accurately.

Step 2: Equipment Configuration

After the requirements are understood, we determine the appropriate configuration of the 60-class extruder, 35-class extruder, feeding system, forming section, cooling system, traction, take-up equipment, electrical controls, and auxiliary components.

The goal is to create a production line that is complete but not unnecessarily complicated.

Step 3: Mechanical Manufacturing

Equipment components are manufactured and prepared according to the agreed design. Mechanical assembly and electrical integration are then carried out as the project moves forward.

At this stage, attention to detail matters. Small issues involving alignment, connections, component installation, or electrical wiring can become larger problems if they are not identified before final testing.

Step 4: Complete Line Assembly

Before shipment, the complete production line is assembled according to the agreed requirements. We check the cooperation between the different sections instead of looking only at individual machines.

Step 5: Testing and Inspection

The complete line is tested and inspected before shipment. The exact inspection scope depends on the agreed project requirements.

I consider this an important part of responsible equipment manufacturing. A customer should not receive a collection of disconnected machines and be expected to figure out how they work together.

Step 6: Packaging

Once testing is completed, the equipment is prepared for transportation. We normally use moisture-resistant materials, protective cushioning, and strong export wooden cases or pallets.

Industrial equipment may experience loading, unloading, handling, storage, vibration, and long-distance transportation. Proper packaging helps reduce avoidable transportation risks.

Step 7: Delivery

Transportation can be arranged by sea, air, or land according to the destination, equipment size, and delivery schedule. Production lead time normally depends on the extruder model, line configuration, customization requirements, and order quantity.

Final Thoughts

A 60+35 Insulation Extrusion Production Line should be selected as a complete production system, not simply as a machine model. The two extrusion units are important, but they are only part of the whole process. Material feeding, extrusion, die forming, cooling, traction, take-up, control, and auxiliary equipment all influence the final production result.

When I work on an extrusion project, I prefer to begin with the product and then work backward toward the equipment. Once we understand the cable structure, material, product size, production capacity, automation needs, and factory layout, we can have a much more useful conversation about the right configuration.

At Wuxi Shuochuan Electromechanical Equipment Manufacturing Co., Ltd., we focus on R&D, manufacturing, and sales of wire and cable extrusion equipment and related automated production systems. Our experience covers photovoltaic cables, automotive wires, electronic wires, communication cables, charging pile cables, and other extrusion-related products.

If you are looking for a 60+35 Insulation Extrusion Production Line manufacturer, a 60+35 insulation extrusion machine, or complete wire insulation extrusion equipment, I recommend starting with your actual product requirements. Give us the cable structure, material information, product dimensions, capacity requirements, and any special production conditions you have. From there, we can work through the equipment configuration step by step.

That is how I believe industrial equipment should be selected: not by chasing a generic specification, but by matching the machine to the product, the process, and the people who will use it every day.
