ADVANTAGES

» Off-line, continuous-circulation cooling loop at main hydraulic unit

» Access to program code can be granted for ease of troubleshooting and process modification (may affect warranty)

» Remote access to the machine’s control system by Nordic Sensors’ technical personnel for fast support and troubleshooting

» Wide use of standard, off-the-shelf parts available from multiple suppliers worldwide

EXTRUSION ASSEMBLY


» Requires little maintenance
» Wearing parts are standard, off-the-shelf products (Timken thrust bearings, KYB hydraulic motor, Parker shot cylinders)
» Stainless steel round hopper
» High-efficiency screw (higher throughput, lower energy consumption)

ENERGY EFFICIENCY


» High-efficiency AC drives
» High-efficiency screw (more efficient plasticization)
» Programming and swing arm servo options for better efficiency
» “On-demand” air cooling system replaces a liquid cooling system with continuous circulation
» Low thermal mass heaters imply faster reaction time and less heat losses
» Removable thermal insulation of the die block assembly can be supplied on request

CYCLE TIME IMPROVEMENT


» High-efficiency screw increases achievable extruder throughput
» Servo programmers allow accurate parison profiling at higher shot speed
» Independent cooling loop at the main hydraulic unit improves stability of hydraulic system operation
» Allen-Bradley PLC with high speed I/O cards ensures stability of the process at shorter cycle times
