PAM (precise, autonomous, mechatronic) is an automation option for flat film extrusion lines. PAM calibrates coextrusion adapters and dies automatically for best comfort, quality, and productivity. The high level of automation makes the machine operator's work significantly easier, thus increasing line productivity and film quality. Once recipes have been set, they can be stored and recalled at the push of a button - even by inexperienced line operators. In addition, energy consumption is significantly reduced compared to an automatic thermal expansion bolt system, as the actuators only need to be supplied with power during the adjustment process and not permanently.
