Gefran products for Blow molding world
Blow molding machines control units and components able to manage the machine functionalities.
• wide range display (from 10.4" up to 15"), touch screen or integrated keyboard
• compact and robust (high resistance to vibrations)
• remote I/Os with Real-Time Ethernet Fieldbus
• easy insering in standard Fieldbus networks (Ethernet, Modbus, CANopen)
• remote Fieldbus keyboards for the machine movements
• remote and independent multiloop controllers available with integrated power units
• SSR with heatsink
Gefran's wide range of sensors offer the ability to measure the primary process variables: position, pressure, force, temperature and humidity.
The sensors portfolio includes:
• new "IMPACT" Melt pressure series specifically designed for the hard Melt applications
• pressure transmitters TPSA/TK for hydraulic pressure
• pressure transmitters TSA for blow pressure control and leak tester
• position transducers with magnetostrictive technology like IK for Parison actuator position control
• position transducers with potentiometric technology (LT) or magnetostrictive technology (MK) can be used for clamp and translation movements
• temperature sensors like thermocouples and RTD with customized designs
• analog and Fieldbus output available
SieiDrive ADV200 and XVy-EV are two drives families designed to control synchronous or asynchronous motors.
The SieiDrive ADV200 inverter can be used with asynchronous motors controlling the Extruders and pump in the Hydraulic machines.
• power range from 0.75kW up to 1.5MW
• Field Oriented Control in Sensorless mode
Servo drive type SieiDrive XVy-EV, for brushless motors, is used for clamp, translations, Parison and nozzle in the Full Electric machines.
• power range from 1.5kW up to 315kW
• Feedback from Resolver, Encoder SinCos and Absolute Encoder EnDat, SSI and Hyperface
Main features:
• communication via GDNet and CANopen
• integrated PLC under standard IEC 61131-3 (5 programming languages)
• configuration tool integrating a software oscilloscope with synchronous sampling (buffered) at 250µsec us for an easy commissioning
