Compounding & Extrusion

Coperion’s modernization services aim for the highest productivity as well as the greatest uptime and operational safety possible for your extruders, compounders, bulk materials plants and components.

Our ZSK machines can be modified ideally to meet the continually growing demands upon production machinery surrounding product quality, power density, machine safety, connectivity, and uptime. Our expert team creates these technical solutions as needed and realizes them together with our clients. We support our customers, beginning with modified part changes all the way up through to turnkey, complex machine modifications for all of our ZSK products, including their auxiliary components.

Advantages for you:

  • Energy savings
  • Extended lifetimes for your machines and plants
  • Increased throughput performance
  • Prevention of unnecessary downtimes
  • Improved product quality
  • Improved reliability
  • Control modernization

Modernization services to optimize your extruder and compounder performance

Drive Unit

In particular, the extruder drive unit motor technology and torque power density must incorporate technical advances. We modernize your machine's entire drive unit to minimize downtime, we prepare for the exchange by pre-installing new motors and gearboxes on a new machine frame, thus shortening conversion time on site to a minimum.

Advantages for you:

  • High electric efficiency for drive motors
  • Lower specific energy for compounding with higher torques
  • Components with optional sensor technology to notify you of needed maintenance, vibration monitoring, etc.
  • Availability of spare parts for modern components guaranteed.

Process Section

Our ZSK extruders’ modular concept system offers ideal opportunities for modernizing. Process tasks and machine configuration involving free volumes and specific torque Md/a³ can be changed just as machine generations can while maintaining the axial distance-specific drive group.

Advantages for you:   

  • Modifications to product developments or new products
  • Increased throughput using our Feed Enhancement Technology (FET) for fill materials and ongoing screw developments
  • Tool optimization for wearing applications

The ZSK’s downstream units are usually designed for one initial application; over the years, they too encounter limitations such as wear, parts availability, process changes, and so forth.
Coperion offers current model series for melt pumps, polymer sieves, strand or underwater pelletizers, and hot die systems. We expertly service auxiliary equipment, such as hydraulic systems, hot oil or water tempering units, and water circulation systems, as well.

Advantages for you:

  • Machine availability and throughput optimization
  • Improved pellet quality
  • Parts availability and downtimes
