Pe pipe extruder

Types of PE pipe extruders

The core components of a PE pipe extruder include an extruder, a die, a cooling system, a cutting system, a control system, and other auxiliary equipment.

• Extruder:

  The extruder is the key element of the PE pipe extrusion machine, which drives and squeezes the plastic melt to form a shape. The structure of the extruder includes a screw, a barrel, a drive unit, etc. The screw length of the extruder is usually 20 to 30 times its diameter, which not only conveys the plastic but also fully mixes and melts it. The barrel has a heating/cooling system that adjusts the temperature of the plastic. The driving unit is usually a motor driving a gear box that can change the speed of the screw, which changes the extrusion speed.

• Die:

  The die is the part that shapes the melted plastic into a specific cross-section. The die plate contains a heated part and a cooled part, which controls the temperature and cooling rate of the plastic. The type and design of the die determines the shape and uniformity of the extruded material.

• Cooling system:

  After the melted plastic is formed through the die, it needs to be cooled and solidified to maintain the shape. Cooling methods include water tanks, air cooling, etc.

• Cutting system:

  After cooling, the material needs to be cut to length and shaped. The cutting system includes saws, blades, etc., which cut the material according to a certain process.

• Control system:

  The control system is responsible for controlling and monitoring the entire extrusion process. It regulates parameters such as temperature, pressure, speed, and more, ensuring that the extrusion process is stable and providing a good quality guarantee for the final product.

• Auxiliary equipment:

  Including feeding systems, drying systems, etc. These devices ensure that the material feeding is stable and the moisture content of the material is appropriate.

Specifications and Maintenance of PE Pipe Extruders

Apart from knowing what a PE pipe extrusion machine does, interested buyers should also know its specifications. Here's a quick look at key specifications of this equipment and what maintenance routines are required.

• Model Number: Usually, the model number of a PE pipe extruder denotes its size and capacity. For instance, in the model number Ø60/13, Ø60 is the diameter range of pipes it can produce, while 13 indicates the screw length to diameter ratio.
• Screw Diameter: The screw diameter of an extruder affects the capacity and melting volume of the equipment. Industrial PE pipe extruders have screw diameters that range from 30 to 120 mm. Bigger screw diameters often have higher outputs.
• Screw Speed: This is the rotational speed of the screw in the extruder. It is usually measured in revolutions per minute (rpm). The screw speed affects the melt flow of the material and the production rate of the extruded product. The screw speed of smaller extruders can be between 50 to 70 rpm, while larger ones can be from 10 to 25 rpm.
• Power: An extruder's motor power determines the force used to drive the screw for melting and pushing material. It is measured in kilowatts (kW) or horsepower (HP). The motor power of small extruders can range from 15 to 37 kW, and large ones from 75 to 250 kW. The motor power directly affects the machine's output capacity.

Maintenance

Proper maintenance is imperative to keep the PE pipe extruder working optimally. It avoids frequent breakdowns that make manufacturing processes less efficient. Here are some simple maintenance tips for this equipment.

• Daily Cleaning: Operators should pay attention to daily cleaning after use. Remove any material residue left in the machine. Clean the barrel, die head, and other parts thoroughly. This prevents blockages and ensures subsequent product quality.
• Lubrication: Regularly apply lubricant to moving parts, such as bearings, chains, and drives. Lubricating regularly minimizes wear and avoids component damage. It also prolongs the service life of the pipe extruder.
• Regular Inspection: Check the conditions of the die head, barrel, and screw regularly. By looking for indicative signs of wear, damage, or leaks, operators can detect and address issues early enough to stop them from worsening.
• Cooling System Maintenance: The extruder's cooling system needs regular maintenance too. Clean the water pumps, pipes, and radiators at intervals to avoid clogging. Ensure that the cooling fan and pump work properly to prevent the equipment from overheating.
• Electrical Checks: From time to time, ensure that the electrical wiring and connections are intact. Check to see that there are no exposed wires or loose connections. Doing this regularly will prevent electrical failures and reduce safety hazards.

Applications of PE Pipe Extruder

Able to cater to the demands of diverse industries, the multimodal PE pipe extruder has become a significant asset for businesses.

• Designing and fabricating of complex shapes like fittings, joints, valves, filters, and other plumbing components.
• The medical sector relies heavily on specialized equipment and procedures to produce high-quality, custom-made products. In the healthcare industry, enforcing strict standards and requiring tailored solutions are essential aspects.
