What to Look for in an Extruder Machine

teamstepupPipe Extrusion

Although achieving optimum production line operation requires many connected machines and equipment, at the heart of every plastics production line is the extruder. It is therefore critically important to know what to look for in an extrusion machine, in order to select the appropriate extruder for your application and gain the most out of your investment.

Single and Double Screw Extruders

DRTS offers a wide range of single or double screw standalone extruder machines, with outputs ranging from 5 to as high as 1200 kg per hour, depending on plastic material properties and application.

To produce PVC piping, a Double Screw Extruder is required for proper powder mixing and processing. On the other hand, for PE piping production a Single Screw Extruder is up to task. Extensive information regarding the two types of piping can be found in the article PE vs. PVC Pipe Extrusion: Which is Right For My Application?.

Ease of use & integration

A plastics extruder machine most often operates as part of a series of downstream connected machines. Therefore, the integration options offered by an extruder are of critical importance to the extruder operation, as part of your production line.

DRTS offers a variety of features that make every extruder machine easy to integrate and operate or simply just a step above the other. Whether as an extruder upgrade to an existing production line, or as part of a new turnkey production line, for Example:

  • Modern PLC/HMI extruder control:

This offers a variety of options in terms of extruder machine communication with a SCADA system and upstream or downstream production line machines, therefore making the extruder easy to integrate and operate seamlessly with any production line.

  • Remote control options:

Providing the extruder machine the ability of on the spot monitoring and data acquisition can be a key factor in line integration and optimizing the extruder machine’s performance. This feature also gives the ability to utilize DRTS online live support without requiring a technicians visit, enabling troubleshooting and addressing production issues in a cost efficient, timely and accurate manner.

  • Direct drive material feeding system:

On double screw PVC extruder machines DRTS uses a direct drive material feeding system instead of a regular dosing system. Direct drive dosing ensures extruder feeding with a precise quantity of material at a consistent pressure. This results are constant extrusion productivity and output, as well as maintaining superior product quality and physical properties, strength and appearance.

 

High quality construction, components & parts

A very important thing to look for when selecting a plastics extruder machine (Extruder), is whether it uses standard off the shelf components from industrial manufacturers (for example by Siemens, Omron, or ABB) instead of locally sourced, no name brand or outdated components. This ensures spare parts availability and ease of servicing, as well as reliable and high performance operation.

Extruder screw, barrel & gearbox

The most important parts of a plastics extruder machine are the screw, barrel and gearbox, which are the components who work the hardest or have the largest product contact and are subjected to extreme thermal as well as mechanical wear and tear.

For the screw & barrel, DRTS uses specialized Bimetallic or Nitrated components, manufactured by leading vendors of metallic industrial parts, for example the high quality German manufacturer Reiloy Metall GmbH. This ensures reliable and predictable extruder machine operation, long extruder life and durability, even in increased technically challenging applications such as Double Screw PVC Extruders.

For the gearbox, DRTS uses Zambello Gearboxes from Italy, combined with motors from ABB, SIEMENS and BAUMULLER, ensuring extruder reliability, durability and consistency.

Electronic components

Using quality electric components is critical for the operation of a plastics extruder machine and ensures good operation, modular parts replacement, easy troubleshooting and low maintenance downtimes.

DRTS uses high quality electronic components from world class leading industrial brands like Siemens, ABB, Omron, Schneider and Celduc. Our extruder machines make use of the latest technological advancements in ceramic heating elements for the barrel, to the B&R, Siemens and Omron control panels and HMI, DRTS ensures its extruders are reliable and productive, while remaining serviceable and easy to use.
