Netstal EVOS 5500-2000 Injection Molding Machine
Year of manufacture: 2015

Very compact, hydraulic, three-plate clamping unit with encapsulated lubrication system, ensuring an oil-free environment in the mold space.
High-precision and wear-resistant linear guides guarantee maximum mold longevity and increased machine availability.
The hybrid injection unit features a modular design and a flexible performance package (metering, clamping, injection) that can be adapted to specific applications.
The highest plasticizing performance and optimal melt quality are ensured by selecting process-appropriate components.
Servo-electric metering drive and state-of-the-art valve technology guarantee energy-efficient operation.
