It also shares practical ABS extrusion troubleshooting techniques, helping companies optimize their production processes and enhance product stability and competitiveness.

2. Industry Background & Challenges

2.1 The Importance of ABS Core Pipes

ABS core pipes play a critical role in providing support and protection for cables and conduits. They must exhibit:

• Dimensional stability: Ensuring consistent inner and outer diameters for smooth cable passage.

• Durability & impact resistance: Maintaining performance under harsh conditions.

• Low friction & smooth surfaces: Reducing abrasion and ensuring reliable installation.

2.2 Market Demand

With the rapid development of fiber optic communication and related industries, the demand for high-quality ABS core pipes continues to grow. Manufacturers face increasing pressure to achieve high-precision extrusion in fiber optic conduit production while minimizing downtime and maintenance costs.

3. Analysis of Causes of ABS Extrusion Clogging

Common causes of clogging in the ABS extrusion process include:

• Inconsistent Material Quality: Moisture, impurities, or substandard ABS pellets can lead to blockages during extrusion.

• Inadequate Temperature & Pressure Control: Fluctuations in extrusion temperature or unstable pressure can cause irregular material flow and clog formation.

• Design Flaws in Equipment: Traditional screw designs with dead zones or high flow resistance allow molten material to stagnate, leading to accumulation and clogging.

Common Issues:

• Impure or moist raw materials

• Temperature and pressure fluctuations

• Outdated screw design

• Inadequate cleaning and maintenance

4. Advanced Anti-Clogging Screw Design

Adopting an advanced anti-clogging screw design is key to mitigating these issues. Such designs offer several advantages:

• Segmented Screw Structure: A multi-stage screw ensures optimal mixing and conveys material uniformly while preventing localized overheating and excessive shear.

• Optimized Geometry: Adjusting the blade angle and spacing reduces material residence time in the screw channel, minimizing clog formation.

• Enhanced Flow Channel Design: Improved die and flow channel geometry guarantees smooth material movement, reducing residue buildup.

Key Features (List):

• Segmented mixing and conveying design

• Optimized blade angle and spacing

• Streamlined flow channel to reduce residue accumulation

• Enhanced material homogenization

5. ABS Core Pipe Extruder Maintenance Protocols

Implementing robust ABS core pipe extruder maintenance protocols is essential for preventing clogging. Key measures include:

Daily Maintenance

• Cleaning and Inspection: Daily cleaning of the screw, die, and sensors to prevent residue buildup.

• Temperature and Pressure Calibration: Regular calibration of sensors to ensure accurate control parameters.

• Lubrication and Component Replacement: Routine lubrication and timely replacement of worn components to sustain efficient operation.

Periodic Overhaul

• Deep Cleaning: Conduct weekly or monthly deep cleaning to remove any accumulated residue.

• System Diagnostics: Utilize data monitoring systems to check the health of the extruder and preempt potential clogging.

• Training and Record Keeping: Regular training for operators and meticulous maintenance records to track equipment performance.
