Conical Twin Screw Extrusion Technology

The ERC 92W uses a conical twin screw extrusion system developed for efficient processing of WPC compounds. The twin screw arrangement provides effective conveying, mixing, homogenization and plasticization of polymer, wood fiber or wood flour and processing additives.

WPC extrusion requires careful control of material temperature, shear, residence time and melt flow. The conical twin screw configuration provides a stable processing platform for preparing a homogeneous WPC melt before the material enters the profile die.

The screw configuration can be optimized according to the polymer system, wood content, formulation, profile geometry and required production output.

110 kW Main Drive System

The 110 kW main motor provides the required drive power for continuous WPC production within the 140–300 kg/h output range. The drive system is designed for stable screw rotation, controlled conveying and reliable operation under industrial production conditions.

Accurate screw speed control helps maintain consistent extrusion output and profile dimensions. The main drive operates together with the feeding and temperature-control systems to provide stable production conditions.

WPC Material Processing

WPC compounds generally combine thermoplastic polymers with wood flour or wood fiber and a range of functional additives. Depending on the product and formulation, materials may include PE, PP or other suitable thermoplastic polymers together with wood fiber, coupling agents, lubricants, stabilizers, pigments and processing modifiers.

The ERC 92W can be configured according to the selected WPC formulation. Polymer type, wood content, moisture level, additive system and profile geometry all influence the required processing conditions and final production output.

Controlled Plasticization and Mixing

Stable plasticization is essential for producing WPC profiles with consistent dimensions, mechanical properties and surface appearance. The ERC 92W is designed to provide controlled conveying, mixing and melting of the WPC formulation.

The extrusion parameters can be adjusted according to material composition and product requirements. This provides flexibility for processing different WPC formulations and profile designs.

Temperature Control System

Temperature management is particularly important during WPC processing because the natural wood component can be sensitive to excessive thermal exposure. The ERC 92W incorporates controlled heating and cooling zones to maintain stable processing conditions throughout the extrusion barrel.

Temperature parameters can be monitored and adjusted according to the WPC compound, polymer type and production requirements. Stable thermal conditions help support consistent melt quality, surface appearance and production stability.

WPC Dry Blend and Compound Compatibility

The EXTRUTEX ERC 92W can be configured for different WPC material systems, including pre-compounded WPC materials and suitable dry-blend formulations.

The extrusion configuration can be adapted according to polymer type, wood fiber content, moisture characteristics, additives and final product requirements. EXTRUTEX engineers can select the appropriate screw, barrel and feeding configuration according to the customer's material system.

WPC Profile Tooling and Die Systems

EXTRUTEX can supply customized WPC profile dies and tooling for the ERC 92W. The tooling can be developed according to profile dimensions, wall thickness, internal cavities, material distribution and surface requirements.

Customized tooling can be manufactured according to customer drawings and product specifications, allowing the ERC 92W to produce standard as well as specialized WPC profiles.

Complete WPC Downstream Equipment

The ERC 92W can be integrated with a complete downstream system including:

• WPC profile extrusion die
• Vacuum calibration table
• Cooling and calibration system
• Profile haul-off
• Automatic cutting machine
• Length measurement system
• Automatic stacking table
• Profile handling equipment

The downstream configuration can be selected according to profile size, geometry, production speed, product length and required automation level.

Vacuum Calibration and Cooling

After leaving the extrusion die, the hot WPC profile enters the calibration and cooling section. Accurate vacuum calibration helps establish the required profile dimensions while controlled cooling improves dimensional stability.

The calibration system can be customized according to the profile geometry and production requirements. Different calibration configurations can be supplied for decking, fencing, wall cladding, construction and technical WPC profiles.

Stable WPC Profile Haul-Off

A reliable haul-off system is essential for maintaining consistent WPC profile dimensions during continuous production. The EXTRUTEX downstream system provides controlled traction after the calibration and cooling section.

Haul-off speed can be synchronized with extrusion output and profile geometry to maintain stable production conditions and consistent finished-product dimensions.

Automatic Cutting and Stacking

After the WPC profile reaches the required cooling condition, it can be cut into predetermined lengths using an automatic cutting system. Cutting parameters can be synchronized with the extrusion line for accurate product lengths.

Automatic stacking equipment can collect and organize finished profiles for packaging, storage or further processing.

WPC Surface Quality

Surface appearance is an important consideration in WPC decking, fencing, wall cladding and decorative applications. Stable extrusion, accurate tooling, controlled calibration and cooling contribute to consistent surface quality.

The ERC 92W can be configured for different WPC surface requirements, including smooth, textured, embossed and customized surfaces depending on the profile tooling and downstream configuration.

WPC Decking Production

The ERC 92W is well suited for industrial production of WPC decking profiles and boards. Decking applications require consistent extrusion output, dimensional stability and controlled surface characteristics.

With suitable tooling and downstream equipment, the system can produce hollow decking profiles, solid decking profiles and customized outdoor construction products.

WPC Fencing and Wall Cladding

WPC fencing and wall cladding profiles can require larger dimensions, specific surface textures and high production stability. The ERC 92W provides a higher-capacity extrusion platform for these applications.

With an approximate output range of 140–300 kg/h, the machine is suitable for manufacturers requiring increased production capacity for medium- and high-volume WPC profile manufacturing.

Customized WPC Profile Solutions

WPC extrusion projects can have different requirements regarding polymer type, wood content, profile dimensions, wall thickness, surface design and production speed.

EXTRUTEX can configure the ERC 92W according to the customer's specific production requirements. The complete solution can include the extruder, feeding system, WPC tooling, vacuum calibration, cooling, haul-off, cutting and stacking equipment.

Industrial Production Performance

With an approximate production capacity of 140–300 kg/h, the ERC 92W is designed for manufacturers requiring a higher-output WPC profile extrusion platform.

Actual output depends on the WPC formulation, polymer type, wood content, moisture level, profile geometry, die design, screw configuration and operating conditions. EXTRUTEX engineers can optimize the machine configuration according to the required application.

Automation and Process Control

The ERC 92W can be equipped with modern control and monitoring systems for extrusion temperature, screw speed, feeding, motor operation and production parameters.

Automation can also be extended to the downstream equipment. Synchronizing the extruder, calibration, cooling, haul-off, cutting and stacking systems helps improve production consistency and simplify machine operation.

Low Maintenance Design

The ERC 92W is designed for industrial operation with convenient access to important components for inspection and maintenance. Regular maintenance of the screws, barrel, gearbox, heaters, cooling system, feeding system and downstream equipment helps maintain stable production.

Preventive maintenance can also help reduce unexpected production interruptions and extend the service life of the extrusion system.
