● Bore Size and Screw Length: The bore size and screw length affect the material flow and the quality of the extruded rubber. Larger bore sizes and longer screws typically allow for higher throughput and better mixing.
● Die Configuration: The design of the die will determine the shape and dimensions of the extruded rubber. Ensure that the extruder machine can accommodate the types of dies needed for your specific products.

Control Systems
Modern rubber extruder machines come equipped with advanced control systems that offer precise monitoring and adjustments. Look for machines with programmable logic controllers (PLCs) and touch-screen interfaces that provide real-time data on temperature, pressure, and speed. These features enhance operational efficiency and consistency in the production process.

Energy Efficiency
Energy consumption is a significant consideration for any manufacturing process. Choose a rubber extruder machine that offers energy-efficient operation to reduce operational costs and reduce environmental impact. Some machines are designed with energy-saving features and technologies that can help lower power consumption and operational expenses.

Maintenance and Support
Regular maintenance is essential for ensuring the longevity and performance of a rubber extruder machine. Consider machines that offer easy access for maintenance and have a good track record of reliability. Additionally, ensure that the manufacturer or supplier provides adequate support and service options to address any issues that may arise.

Material Compatibility
Compatibility with different types of rubber compounds is crucial for flexibility in production. Verify that the rubber extruder machine can handle the specific materials you use and can accommodate any changes in formulations or additives. This versatility can help streamline production and reduce downtime associated with material changes.

Barrel
The barrel is a crucial component of the rubber extruder machine. It is where the raw rubber material is heated, mixed, and transformed into a molten state before being extruded through the die. The barrel's primary functions include providing the necessary heat for melting the rubber and facilitating the mixing of additives.

● Heating Elements: The barrel is equipped with heating elements that regulate the temperature of the rubber. Accurate temperature control is essential for achieving the desired properties of the final product, such as flexibility and durability. Modern rubber extruder machines often feature advanced temperature control systems that ensure precise and consistent heating.

● Cooling Systems: In addition to heating, the barrel may also include cooling systems to maintain temperature conditions and prevent overheating. Effective cooling is important for maintaining the quality of the rubber and preventing defects in the extruded product.

Screw (Auger)
The screw, or auger, is another critical component of the rubber extruder machine. It is responsible for moving the rubber material through the barrel and ensuring proper mixing and melting. The design and performance of the screw significantly impact the efficiency of the extrusion process.

● Screw Design: The screw's design, including its geometry and materials, influences the mixing, kneading, and pumping of the rubber. Modern rubber extruder machines feature screws with optimized designs to enhance performance and handle various rubber compounds. These designs improve the uniformity of mixing and ensure consistent extrusion.

● Screw Speed: The rotational speed of the screw affects the rate at which the rubber is processed. Adjusting the screw speed allows for control over the extrusion rate and the quality of the final product. High-performance rubber extruder machines offer precise control over screw speed to meet specific production requirements.

Die
The die is the component through which the molten rubber exits the extruder machine, taking on the desired shape or profile. The design of the die is critical for achieving the correct dimensions and characteristics of the extruded product.

● Die Design: The die's shape and configuration determine the final profile of the rubber. Different types of dies, such as flat dies or round dies, are used depending on the product being manufactured. High-performance rubber extruder machines use dies that are designed for specific applications to ensure accurate and consistent results.

● Die Temperature Control: Maintaining the appropriate temperature at the die is essential for the proper solidification of the rubber. Many modern extruder machines feature temperature control systems that regulate the heat at the die, contributing to the overall quality of the extruded product.

● Temperature Controllers: Accurate temperature control is crucial for the extrusion process. Modern rubber extruder machines are equipped with advanced temperature controllers that provide real-time monitoring and adjustments to maintain the desired temperature throughout the process.

● Pressure Regulators: Pressure regulation is important for controlling the flow of rubber through the extruder and ensuring consistent extrusion. High-performance machines include pressure regulators that maintain pressure levels for different rubber compounds and product specifications.

● Automation: Many modern rubber extruder machines feature automated control systems that streamline operations and reduce the need for manual intervention. Automation enhances precision and efficiency, allowing for consistent production and reduced downtime.

The rubber extruder machine head should be assembled together and installed on the extruder as a whole.
Before assembling the machine head, wipe off the grease applied during storage, carefully check the cavity surface for bruises, scratches, and rust spots, perform necessary polishing, and then apply a layer of silicone oil on the surface of the runner.
Assemble the plates of the machine head in order, apply high temperature grease to the threads of the bolts, and then screw on the bolts and flanges.
Put the perforated plate between the flanges of the machine head to ensure that the perforated plate is pressed tightly without overflow.
The horizontal position of the die should be adjusted before the fastening bolts of the connecting flange between the die head and the extruder are not tightened. The square die head can be adjusted horizontally, and the round die head should be based on the bottom surface of the finalized model. The bottom of the mold is leveled.
Tighten the connecting flange bolts, tighten the machine head fastening bolts, install the heating ring and thermocouple, pay attention to the heating ring to be close to the outer surface of the machine head.
Install the sizing sleeve and adjust it in place, check whether the center line of the main engine, the sizing sleeve and the tractor are aligned. After adjustment, tighten the fixing bolts. Connect the water pipes and vacuum tubes of the sizing sleeve.
Turn on the heating power supply to evenly heat up the machine head and cylinder. At the same time, open the cooling water at the bottom of the hopper and the gear box and the inlet valve of the exhaust vacuum pump. When heating, the temperature of each section is first adjusted to 140℃, and the temperature is kept for 30-40min when the temperature rises to 140℃, and then the temperature is raised to the temperature during normal production.
