High-precision blow molder
Source: CAN Newsletter September 2004
Ossberger manufacturer of injection blow molding machines such as the SB2/60, uses CANopen for networking the blow molder. The manufacture of products such as CV joint boots, steering rack boots, and other tubular products with varying diameters place high demands on precision.
Used in the automotive industry, these products are subject to continuous dynamic loading, and must withstand a wide range of road and weather conditions. The mechanical forces acting on these components, plus large temperature variations and contamination from oil, tar, salt, and brakepad dust require top quality materials ad exact production methods. The company uses a human machine interface with touch screen for controlling the blow molding machine, this enableing the machine operator to switch motors and heating zones on and off, select a different operating mode or a particular function. Similarly, all process values as well as texts can be entered via the screen at the touch of a finger. For further processing, these data are transmitted to the various slave devices via CANopen.
