Say “manufacturing automation” and thoughts immediately go to the shop floor and specialized production equipment, robotics and material handling systems. But there is another realm of possible automation — the front office.

Successfully starting or restarting an injection molding machine is less about ticking boxes on a rote checklist and more about individually assessing each processing scenario and its unique variables.

Mike Sepe has authored more than 25 ANTEC papers and more than 250 articles illustrating the importance of this interdisciplanary approach. In this collection, we present some of his best work during the years he has been contributing for Plastics Technology Magazine.

During in-mold labeling, a label is inserted into the thermoforming mold that shapes the product and forms a solid bond with the finished product. Shaping and decoration are performed in a single, efficient process.

“Greiner Packaging offers various barrier solutions, which increase protection against oxygen or light and, thus, make food last longer,” Eisenhuber told PlasticsToday. “Our barrier solution of choice is a PP-EVOH-PP combination, which we call multi-barrier technology (MBT). It is hard to make a general statement about how barrier solutions will extend the shelf life of a product," Eisenhuber adds, “as this depends on many factors other than the packaging – such as the filling conditions and the type of filling itself.”

Mold maintenance is critical, and with this collection of content we’ve bundled some of the very best advice we’ve published on repairing, maintaining, evaluating and even hanging molds on injection molding machines.

Mastip told Plastics Technology that initially the valve gates will be pneumatically actuated, while the company is looking at servo actuation down the road. Mastip said drops can range up to 128, with gate diameters from 0.4 to 1.2 mm and nozzle lengths of 50, 70 and 90 mm. The nozzles are made from 2316 corrosion resistant steel, with cold decks fabricated from P20 or 420 corrosion resistant steel.

Processors with sustainability goals or mandates have a number of ways to reach their goals. Biopolymers are among them.

Initially available with four drops, the cold runner system features cooled valve-gated nozzle for delivery of LSR directly into a part. Mastip says cooled plates ensure the silicone remains liquid, with cooling channels in the nozzle to deliver material in optimum condition. The cavity mount plate is heated with Mastip’s established heater technology and insulation board separates the cooled plates from the heated ones, with hardened side lock guides used to control thermal expansion between the two.

IML typically is used in combination with injection molding technology. The thermoformed IML cups are more sustainable by several measures, according to Philipp Maurer, Key Account Manager at Greiner Packaging. Less plastic is required to produce thermoformed cups, which saves resources and makes the cups lighter and less costly to transfer. This requires fewer carbon dioxide emissions during transport.
