Netstal EVOS 5500-2000

Netstal EVOS 5500-2000 Injection Moulding Machine
Year of Manufacture: 2015

Highly compact, hydraulic, three-platen clamping unit with encapsulated lubrication system providing an oil-free environment within the mould area.
High-precision, wear-resistant linear guides ensure maximum mould longevity and highest machine availability.
The hybrid injection unit features a modular design and a flexible performance package (plasticizing, holding pressure, injection) that can be configured for the application.
Maximum plasticizing performance and optimal melt quality are guaranteed by selecting process-appropriate components.
Servo-electric dosing drive and advanced valve technology ensure energy-efficient operation.
