Injection molding machines Engel has added liquid silicone rubber (LSR) micromolding to the applications for its injection molding machines that are equipped with electric injection units.
What’s new? A micro-injection unit that can be retrofitted to existing Engel presses, with some limitations, based on machine size and the application. The unit, which features a quick coupling system, also is available with new Engel machines. Engel has used the micro-injection unit to mold parts for ophthalmic diagnostic instruments, each weighing 0.0013 gram. They were produced on an all-electric, tiebarless Engel e-motion 50/30 TL machine, shown.
Benefits Precision molding of microparts and flexibility. Thanks to the quick coupling system, the unit can be swapped out for a conventional screw injection unit in less than 30 minutes, maximizing machine uptime.
