When we talk about a Plastic Extruder, we usually talk about one machine. In real production, however, the machine is only one part of a much bigger process. Material feeding, heating, plasticizing, extrusion, cooling, traction, take-up, and process control all have to work together. If one part is poorly matched, the final product can still have problems even when the extruder itself is running normally.

Our 70 Extruder is designed for continuous thermoplastic processing and can be configured for different industrial extrusion applications. At Wuxi Shuochuan Electromechanical Equipment Manufacturing Co., Ltd., we develop and manufacture extrusion equipment and complete Production Lines for wire, cable, photovoltaic cable, automotive wire, electronic wire, communication cable, charging pile cable, and other plastic extrusion applications.

We approach the 70 Extruder from a practical production point of view. Instead of simply asking whether a machine can extrude plastic, we first look at what the customer needs to make, which material will be processed, how much output is required, what product dimensions are expected, and how the finished product will move through the rest of the line.

The 70 Plastic Extruder can therefore be used as a standalone extrusion machine or as part of a larger automated extrusion production line. Depending on the project, it can be combined with cooling systems, traction equipment, Take-up Machines, unwinding equipment, control systems, and other auxiliary machinery.

One detail is important for buyers: the number “70” should not automatically be treated as the production output of the machine. Model numbers and nominal designations do not by themselves tell us how many kilograms per hour the machine can produce. Actual production capacity depends on material, screw configuration, screw speed, die design, product dimensions, temperature conditions, and the complete line arrangement.

1. What Is a 70 Extruder?

A 70 Extruder Machine is an industrial machine used to continuously process suitable thermoplastic materials. The basic job is quite simple: feed plastic into the machine, heat and plasticize it, move the melt forward with a rotating screw, and force it through a die to create the required shape.

The finished product can take many forms. Depending on the tooling and downstream equipment, extrusion can be used for wire insulation, cable sheathing, plastic profiles, tubes, strips, and other continuous products.

What makes extrusion useful in industrial production is its continuous nature. Instead of processing one piece at a time, the material can move through the machine for an extended production run. This makes extrusion suitable for factories that need steady output and repeatable processing.

In our experience, the most important part of selecting an extruder is not simply choosing a larger or smaller model. The machine needs to match the product.

For example, a manufacturer producing photovoltaic cables may have different requirements from a company producing plastic profiles. An automotive wire producer may pay close attention to insulation thickness and line stability, while a profile manufacturer may care more about die geometry and product shape.

That is why we normally collect product information before recommending a configuration. We want to know the material, product size, expected output, production method, automation level, and existing factory conditions.

This table describes the general extrusion process. The actual configuration of a 70 Extruder should be confirmed according to the specific product and material.

2. How Does the 70 Extruder Work?

The working principle of the 70 Extrusion Machine is based on controlled movement and heating of thermoplastic material.

First, the raw material is supplied to the feeding section. Depending on the Production Process, this may be plastic pellets, compounds, or another suitable thermoplastic feedstock.

The material then enters the barrel. Inside the barrel, the rotating screw moves the material forward while heat is supplied through the heating system. Mechanical movement and heat gradually soften and melt the material.

At this point, we are not simply trying to make the plastic hot. We want the material to reach a suitable and stable melt condition. If the material is not properly plasticized, the extrusion process may become unstable. If it is exposed to unsuitable thermal conditions, material quality can also be affected.

The screw continues to move the melt toward the front of the machine. The melt then enters the die, which determines the basic shape of the extruded product.

For cable production, the tooling may be arranged to apply insulation or a sheath around a conductor. For profile extrusion, the die may create a specific cross-sectional shape. For tubes or other continuous products, the tooling is designed around the required geometry.

Once the material leaves the die, it is usually still hot and needs to be cooled. Depending on the product, water cooling, air cooling, sizing equipment, or a combination of systems may be used.

The product is then pulled by traction equipment and collected by a take-up system or transferred to the next production stage.

This is why we always look at the whole line. Imagine the extruder producing material at a stable rate while the traction speed changes too much. The final product may still show dimensional variation. The same is true if the cooling system is not properly matched to the production speed.

In short, stable extrusion is a team effort between the extruder and its supporting equipment.

A Simple Cable Extrusion Example

Take an insulated wire as an example. A conductor enters the production line, while thermoplastic insulation material is fed into the 70 Cable Extruder. The material is melted and conveyed through the screw. The die then forms the insulation around the conductor.

The newly coated wire passes through a cooling section. After cooling, traction equipment pulls the wire through the line at a controlled speed, and a take-up machine winds the finished product.

Every stage affects the final result. The extruder needs stable melt flow. The die needs to match the product. Cooling needs to be sufficient. Traction needs to remain steady. Take-up tension needs to be controlled.

This is the kind of production relationship we consider when configuring equipment for our customers.

3. Main Features of Our 70 Plastic Extruder

Continuous Thermoplastic Processing

The 70 Industrial Extruder is intended for continuous processing of suitable thermoplastic materials. This makes it a practical choice for production environments where long and steady extrusion runs are required.

Continuous production can also reduce repeated manual handling. Once the process is properly set up, operators can monitor the line and make adjustments according to actual production conditions.

Controlled Feeding and Plasticizing

Material feeding is one of the first places where extrusion quality can be affected. If the feed is unstable, the amount of material entering the process can change, which may influence melt flow and final product dimensions.

We therefore pay attention to feeding stability when configuring the machine.

Plasticizing is equally important. The screw needs to transport and melt the material in a controlled way. The correct screw arrangement depends on the material and product application, so we do not recommend using exactly the same configuration for every project.

Practical Temperature Control

Temperature is one of the basic controls in plastic extrusion. Different materials may require different processing conditions, and even the same material can behave differently when product size, output, or screw conditions change.

The heating system should therefore be considered together with material characteristics, screw design, barrel arrangement, and production requirements.

For operators, the goal is simple: maintain a stable and understandable process rather than constantly chasing temperature changes.

Flexible Downstream Integration

Our 70 Extruder Machine can be integrated with different downstream systems according to the application. These may include cooling tanks, air cooling equipment, traction machines, take-up units, unwinding systems, measuring equipment, and other Auxiliary Equipment.

This makes the machine suitable for projects ranging from a relatively simple extrusion process to a more automated production line.

Designed Around the Production Process

We do not believe that every customer needs the same machine configuration.

A manufacturer with one product and a simple production process may need a straightforward setup. A cable factory producing several product specifications may need more flexible control and supporting equipment.

Our job is to understand the difference and configure the equipment accordingly.

4. Technical Factors That Affect Extrusion Performance

When customers compare a 70 Extruder for Plastic Processing with another machine, it is tempting to focus on price, motor power, or model number. Those figures can be useful, but they do not tell the complete story.

From a production point of view, we recommend looking at several factors together.

Material Characteristics

The first question we ask is always about the material.

Different thermoplastics have different melting behavior, viscosity, thermal sensitivity, and processing requirements. PVC, PE, PP, and other materials cannot simply be treated as identical materials.

Material suppliers often provide processing recommendations. These recommendations should be considered during equipment configuration and trial production.

If a customer plans to process more than one material, we also need to understand how frequently the material will be changed and whether the machine configuration should support that production pattern.

Screw Configuration

The screw is one of the most important working parts inside an extruder.

It transports the material, helps generate the mechanical work required for plasticizing, and pushes the melt toward the die. Screw geometry can influence melt quality, conveying behavior, pressure, and production stability.

For this reason, screw selection should be based on the material and application rather than simply choosing the screw used by another factory.

Barrel and Heating System

The barrel provides the main processing space around the screw. Heating sections allow the operator to establish the required temperature profile.

The actual temperature settings should be based on the material, screw configuration, production rate, and process behavior.

Good temperature control is not about making every section as hot as possible. It is about giving the material the right conditions at the right stage.

Die Design

The die is responsible for shaping the melt.

For wire and cable applications, die design affects how the insulation or sheath is applied around the conductor. For profiles, the die controls the cross-sectional shape. For tubes, the tooling needs to support the required tube geometry.

A well-configured extruder still needs suitable tooling. We therefore consider the die and downstream process as part of the extrusion solution.

Cooling

Once the product leaves the die, it needs to stabilize.

Cooling conditions depend on the material, product size, production speed, and product structure. A cable insulation layer, a plastic profile, and a larger tube may require very different cooling arrangements.

Cooling should therefore be selected according to the product rather than simply added as a standard accessory.

Traction and Take-Up

Traction equipment controls how the product moves through the production line. Take-up equipment collects the finished product.

For continuous products, speed and tension are important. If the traction system and extruder are not properly synchronized, product dimensions may change.

This is particularly important for wire and cable applications, where small changes in coating thickness can matter.

5. Quality and Testing Considerations for Plastic Extrusion

We believe that a good extrusion machine should be evaluated through the actual production process, not just by looking at its appearance or a list of components.

For plastic products, material testing and production control are closely related. ASTM D638-22 is a standard test method for tensile properties of plastics. ASTM explains that tensile data are useful for material control, specification, characterization, research, and engineering applications, while also noting that results can change with specimen preparation, testing speed, and environmental conditions.

This point is important for manufacturers: a test number is meaningful only when the test conditions are properly controlled. The same principle applies to extrusion. When comparing production results, material, temperature, line speed, product dimensions, and other conditions should be kept consistent.

Source: ASTM International and ISO official publications. ASTM D638-22 specifically notes that tensile results are sensitive to specimen preparation, testing speed, and environmental conditions. ISO describes ISO 9001 as a quality management standard covering requirements for establishing, maintaining, and continually improving a quality management system.

For our equipment projects, we use the customer's agreed requirements as the practical reference for inspection and testing. Before shipment, the complete machine or production line is assembled, tested, and inspected according to the confirmed requirements.

6. Applications of the 70 Extruder

The 70 Extruder can be used in different thermoplastic processing applications when the material and equipment configuration are suitable.

Wire and Cable Production

Wire and cable manufacturing is an important application area for our extrusion equipment.

A suitable 70 Cable Extruder can be integrated with conductor feeding, extrusion tooling, cooling, traction, and take-up equipment to create a continuous production line.

In this type of application, operators normally pay close attention to insulation or sheath thickness, outer diameter, surface condition, production speed, and material stability.

The extrusion machine therefore needs to work together with the rest of the line rather than operate as a completely independent unit.

Photovoltaic Wire and Cable

Photovoltaic wire and cable production is another area where extrusion equipment can be used.

Depending on the product design, suitable materials and tooling are selected for the insulation and sheath. The complete line may include extrusion, cooling, traction, take-up, and other equipment.

Our company develops photovoltaic wire and Cable Production Lines and can configure extrusion equipment around the customer's production requirements.

Automotive Wire

Automotive Wire Production requires consistent processing because the finished wire must meet the specified construction and material requirements.

A 70 Wire Extrusion Machine can be integrated into an automotive Wire Production Line according to the conductor, insulation material, product dimensions, and required production capacity.

We pay particular attention to process stability and line coordination when dealing with continuous wire products.

Electronic Wire

Electronic wire applications can also use plastic extrusion for insulation and other non-metallic layers.

Depending on the product, the extrusion system may need to handle relatively small dimensions and controlled coating conditions. The machine configuration should therefore be selected according to the actual product rather than simply the general category of “electronic wire.”

Network Communication Cable

Communication cable production is another application where stable extrusion can be important.

The extruder may be used to apply suitable insulation or other plastic layers around conductors. The required die, material, cooling, traction, and take-up arrangement depends on the cable construction.

Charging Pile Cable

Charging pile cable production also involves continuous cable extrusion processes. Depending on cable construction and material selection, an extrusion line can be configured for insulation or sheath production.

Our product range includes charging pile cable production lines, allowing us to consider the extruder together with the other equipment required for the complete manufacturing process.

Plastic Profiles and Other Extruded Products

Outside the cable industry, suitable thermoplastic materials can also be processed into profiles, tubes, strips, and other continuous products.

In these applications, die design becomes especially important because the die directly influences the product shape.

7. Comparing Different Extrusion Equipment Approaches

There is no single extrusion machine that is right for every factory. A customer with an existing cooling and take-up system may only need a main extruder. Another customer starting a new cable production line may need the complete system.

For us, the best solution is the one that fits the customer's actual production conditions. Bigger equipment is not automatically better. More automation is not automatically better either. The right level of equipment should be based on product requirements, production volume, labor conditions, factory layout, and future plans.

8. How We Manufacture and Deliver the 70 Extruder

At Wuxi Shuochuan Electromechanical Equipment Manufacturing Co., Ltd., we integrate R&D, manufacturing, and sales. We have obtained more than ten utility model patent certificates, reflecting our continued work in equipment development and practical mechanical solutions.

Our manufacturing process begins before the machine is physically built.

Step 1: Confirm the Customer's Requirements

We first discuss the material, product dimensions, output requirements, equipment configuration, factory conditions, and expected delivery schedule.

If the customer is ordering a complete production line, we also need to understand the upstream and downstream equipment and the available factory space.

Step 2: Develop the Equipment Configuration

After the requirements are clear, we determine the suitable equipment arrangement.

This may include the 70 Extruder, screw and barrel configuration, heating and control system, extrusion tooling, cooling equipment, traction, take-up, unwinding equipment, and other auxiliary systems.

Step 3: Manufacturing and Assembly

The machine is manufactured and assembled according to the agreed configuration. Mechanical components, electrical controls, and auxiliary equipment are brought together into the required production system.

Because we manufacture complete extrusion production lines as well as individual machines, we can consider how the different sections of the line need to work together.

Step 4: Testing and Inspection

Before shipment, the complete machine or production line is assembled, tested, and inspected according to the agreed requirements.

This stage is important because it gives us a chance to identify equipment coordination problems before the machine reaches the customer's factory.

Step 5: Packaging

For export orders, we normally use moisture-resistant materials, protective cushioning, and strong wooden cases or pallets. Packaging is selected according to equipment dimensions, transportation conditions, and destination.

Step 6: Transportation

Depending on the destination and project schedule, transportation can be arranged by sea, air, or land.

9. Why Work With Shuochuan for a 70 Extruder?

When a company buys an industrial extruder, it is making a production investment. The machine may run for years, so the decision should not be based only on the initial purchase price.

We believe customers should also consider engineering support, equipment matching, production-line experience, inspection, documentation, delivery, and communication.

Wuxi Shuochuan Electromechanical Equipment Manufacturing Co., Ltd. integrates research and development, manufacturing, and sales. Our product range covers high-speed extruders and a variety of automated extrusion production lines.

Our main products include three-in-one BV extrusion automatic production lines, three-in-one plus one BVVB automated production lines, photovoltaic wire and cable production lines, automotive wire production lines, electronic wire production lines, network communication wire production lines, cable production lines, charging pile cable production lines, take-up and unwinding equipment, auxiliary equipment, and related raw materials.

This range gives us a useful perspective when working on a 70 Extruder project. We are not looking at only one machine. We can consider the machine as part of a larger production process.

The company has also stated that it has passed ISO 19001 quality management system certification. Because the commonly recognized ISO quality-management standard is ISO 9001, procurement teams should verify the exact certificate wording, number, and edition against the original company certificate during supplier qualification. ISO describes ISO 9001 as a framework for establishing, maintaining, and continually improving a quality management system.

Our corporate spirit is “Quality First, Continuous Improvement, and Honest Service.” We try to apply that idea in practical work: understand the customer's product, configure the machine carefully, test it before shipment, and communicate clearly throughout the project.

Conclusion: Choose the 70 Extruder Around Your Product

After years of working with extrusion equipment, we have found that choosing an extruder becomes much easier when the discussion starts with the product rather than the machine.

What material are you processing? What product are you making? What dimensions are required? How much output do you need? What level of automation do you want? What equipment do you already have?

These questions tell us much more than a model number alone.

The 70 Extruder is designed as a practical solution for continuous thermoplastic processing and can be used in wire and cable, photovoltaic cable, automotive wire, electronic wire, communication cable, charging pile cable, plastic profile, and other suitable extrusion applications.

For us, the machine is only successful when it works properly as part of the customer's production process. The extruder, die, cooling system, traction equipment, take-up unit, electrical controls, and other auxiliary equipment should form a coordinated system.

At Wuxi Shuochuan Electromechanical Equipment Manufacturing Co., Ltd., we combine R&D, manufacturing, and sales to develop extrusion equipment and complete production solutions. We can work with customers on individual extruders as well as larger automated production lines.

If you are evaluating a 70 Plastic Extruder, 70 Extrusion Machine, 70 Cable Extruder, or 70 Wire Extrusion Machine, we recommend starting with your actual production requirements. Once the material, product, output, and line configuration are clear, we can work toward an equipment solution that makes sense for your factory.

That is the approach we prefer: no unnecessary complexity, no guessing at specifications, and no one-size-fits-all configuration. We focus on building an extrusion system that can be understood, operated, tested, delivered, and put into real industrial production.
