With the use of an all-electric and tie-bar-less ENGEL e-motion 30 TL injection molding machine, the smallest precision components for the field of ophthalmology which weigh just 0.0005 grams can be produced. 

Collaborated with ACH Solution, ENGEL enables the production of precision components made of liquid silicone rubber (LSR) with shot weights of well below 0.1 grams.

The all-electric and tie-bar-less ENGEL e-motion 30 TL injection moulding machine is equipped with a LSR metering pump by ACH Solution, an ENGEL viper 6 linear robot for micro-part removal and depositing on a conveyor belt, and a camera system for quality control also from ACH Solution. Moreover, a 32-cavity valve gate cold runner mold is used.

The focus during the development of the micro-injection unit was on a high degree of flexibility. Thanks to the quick coupling system, the unit can be exchanged for a conventional screw injection unit in less than 30 minutes to maximize the production uptime of the injection moulding machine.

The target group for the tie-bar-less, all-electric e-motion TL machine in combination with the new micro-injection unit is both medical technology and the consumer electronics industries, which produces very small electronic precision parts and high-quality optical components for smartphones, among other things.
