Davis Standard | 10 Tips to Keep Your Extruder Pumping

In many ways, your extruder is like the engine of your car. You need to keep it fine-tuned and operating at peak performance for best results and fewer breakdowns. When the engine runs well, you get the best mileage and reliability from your investment. Likewise, we want you to get the most from your extruder in terms of performance and durability.

In this blog, we once again delve into maintenance by focusing on the extruder. Our team has put together their top 10 tips for keeping your extruder in top condition.

Tip 1

Download the “Davis-Standard Quarterly Extruder Performance Checklist,” and ensure your team is monitoring and maintaining your equipment in adherence to OEM standards.

Tip 2

Monitor gearcase oil conditions weekly. Change the gearcase oil every six months or 4,000 hours of operation. For more information, check out these references:

Tip 3

Measure screw OD and barrel ID annually, and keep track of wear for ideal processing conditions. Your regional sales manager can advise you on wear concerns. Check out the screw wear guidelines here.

Tip 4

Check barrel heater bolts for tightness and correct heater contact every 12 months.

Tip 5

 Examine breaker plates and spacer rings for flatness before installation. Confirm there is a tight seal between the barrel and die.

Tip 6

 Make sure cooling water is piped and flowing to the feed section in order to efficiently convey pelletized material.

Tip 7

Inspect motor surfaces and air intakes to ensure they are clear of debris.

Tip 8

If you notice a significant performance decline and are seeking improved efficiency, it may be time for an upgrade. This can include control systems, dies, process modification, refurbishing the gearcase, and more. Contact your regional sales manager for details.

Tip 9

For advanced machine monitoring for predictive and preventive maintenance consider the DS Activ-Check system.
