The Alpine 65MM Extruder Screw stands out as a reliable choice for mid-range extrusion machines, especially those handling polyethylene films. This post explores the key features, technical specifications, and practical benefits of this extruder screw, helping you understand why it fits well with Alpine HS65-18D machines and similar units.
Key Features of the Alpine 65MM Extruder Screw
This extruder screw is designed with precision to meet the demands of polyethylene film production. Here are the main features that make it a preferred component:
Diameter: 65 millimeters, suitable for mid-range extrusion machines.
Overall Length: 57.362 inches, providing an optimal length for thorough melting and mixing.
Grind Mixer Length: 6.000 inches, ensuring effective material homogenization.
Compression Ratio: 18:1, which balances melting efficiency and pressure generation.
These specifications contribute to consistent output quality and stable machine operation.
Compatibility with Alpine HS65-18D and PEES 220/T/65/AL Units
The Alpine 65MM Extruder Screw is primarily designed for the Alpine HS65-18D extruder and associated PEES 220/T/65/AL monoextruder units. These machines are widely used in the production of high-density polyethylene (HDPE) and low-density polyethylene (LDPE) films.
The screw length corresponds to a Length-to-Diameter (L/D) ratio of approximately 20.5:1 or 21:1. This ratio is standard for mid-range Alpine HS series extruders, providing a good balance between melting capacity and throughput.
Production Capacity and Performance
Machines equipped with this screw typically achieve a maximum throughput of around 120 kilograms per hour. This capacity suits manufacturers aiming for steady production without sacrificing material quality.
The 18:1 compression ratio plays a crucial role in this performance. It allows the screw to generate enough pressure to melt and homogenize the polymer effectively while maintaining a smooth flow through the die. The 6-inch grind mixer section further improves material consistency by breaking down agglomerates and ensuring uniform melt temperature.
Practical Benefits for Film Production
Using the Alpine 65MM Extruder Screw offers several advantages in film extrusion processes:
Improved Melt Quality: The screw design promotes thorough melting and mixing, reducing defects in the final film.
Stable Throughput: Consistent output rates help maintain production schedules and reduce downtime.
Versatility: Compatible with both HDPE and LDPE, it supports a range of film thicknesses and applications.
Reduced Wear: High-quality materials and precise manufacturing extend screw life, lowering maintenance costs.
These benefits translate into better product quality and operational efficiency for plastic film manufacturers.
Installation and Maintenance Tips
To get the most out of the Alpine 65MM Extruder Screw, proper installation and maintenance are essential:
Alignment: Ensure the screw is correctly aligned with the barrel to avoid uneven wear.
Cleaning: Regularly clean the screw and barrel to prevent material buildup, which can affect melt quality.
Inspection: Check for signs of wear or damage, especially on the flights and mixing sections.
Lubrication: Follow manufacturer guidelines for lubrication to maintain smooth operation.
Routine care helps maintain performance and extends the screw’s service life.
