If money were no object, then most of us would opt to buy new. But money matters, plenty, so sometimes we need to reuse and refurbish. That was the case for flexible plastic films processor/converter Amgraph, which had a 75-feet (23m) long Black-Clawson two-station extrusion laminator it wanted to upgrade to meet new customer requirements.

Business is easier and faster for processors requiring repairs of their gear pump from Maag Pump Systems. The merger last year of Switzerland's Maag with pelletizing machinery manufacturer Automatik Plastics Machinery GmbH means that, starting now, processors can avoid sending the pumps to Switzerland—and through laborious Swiss customs—and now can instead have them repaired or serviced at Automatik's facility in Germany.

In PET sheet extrusion, the maintenance and preservation of the material's intrinsic viscosity (IV) is a key requirement of the process. If IV drops below a certain level, the end product mechanical properties can be compromised to unacceptable levels.

A rugged, energy-efficient drive boasting a compact footprint, lower total cost-of-ownership and moreover enhanced usability is equally at home controlling motion in material handling systems or packaging conveyors. The Sinamics G110D drive from Siemens (Atlanta, GA) is ideal for installation in close proximity to motors located throughout facilities where dust and water ingression are a concern.

The eDart System from RJG has three software modules: The eDart flx allows processors to use in-cavity pressure and temperature sensors to see what's happening in the mold, discover which parameters are essential to your product quality, and automatically divert rejected parts.

Servomotors promising shorter machine cycles due to higher dynamic response are the latest additions to the 1FT7 family from Siemens Industry Inc. (Elk Grove Village, IL). Another plus is less downtime resulting from the new rigid vibration-insulated encoder mounting. This design also enables the user to exchange the encoder in the field in less than 5 minutes, without encoder alignment. High-resolution encoders, currently up to 22-bit, enable these servos to become highly precise motion control system components.

Watlow’s (St. Louis, MI) new EZ-Zone PM Express panel-mount PID control provides advanced control functionality with a basic user interface. It features a friendly user interface supported by two menus and a streamlined list of parameters—appropriate for basic applications and user levels—plus the Express menu eliminates complexity and reduces training costs and user errors.
