Apr 01, 2010 · A temperature sensor in the tool signals a change to the mold temperature. RocTools latest development targets high-temperature resins like PEEK. To mold a 900-g PEEK part measuring 60 x 50 cm x 2.2 mm thick, the tool was heated to 330 C (626 F), allowing a single gate to deliver flow lengths of 400 mm (vs. 200 mm at 180 C mold temp) while

INJECTION MOLDING: Improving Barrel-Temperature

There are hundreds of processing variables to control in injection molding, and the temperature of the plastic has to be among the top five in importance. No arguments here: Temperature control is critical, and you should duplicate the plastic temperature shot-to-shot, run-to-run, and machine-to-machine. But what bothers me is that many molders do not differentiate between the actual plastic temperature

INJECTION MOLDING: Infrared Sensors - Plastics Technology

Sep 28, 2015 · Thus, knowing the actual plastic temperature as the runner and part cool allows better decisions on injection speeds, pack pressures, mold temperatures, cooling time, and cycle time. Futaba sources also say melt-temperature sensing is useful for detecting end-of-fill in mold cavities, due to its fast (8 millisec) response rate.

Injection Molding: Nozzle Heaters - Plastics Technology

Jan 02, 2018 · Second, nearly every time we do any of the above routinesor when there is a leak in the nozzle-body assembly or junction of the nozzle tip and sprue bushingmolten plastic comes out and gravity works to allow the plastic to cover the wires. Know How Injection Molding: Get more insights from our injection molding experts.
