Micro-Injection Molding of Liquid Silicone Rubber (LSR) | PTXPO 2023 In-Booth Demo 

At #PTXPO23 ‪@Engelglobal‬ showcased precision micro molding of LSR with ACH Solutions. The interaction of a 32-cavity precision mold, a newly developed micro-injection unit, and the tie-bar-less, all-electric ENGEL e-motion 30 TL injection molding machine produce high-precision components for ophthalmic measuring instruments with a part weight of just 0.0005 grams. Its smart software solution "IQ weight control" plays a key role in the production process: the self-optimizing program ensures highly consistent shot weights despite viscosity differences of the two-component LSR material and is used successfully in many cases, especially in the processing of elastomers.
