Power Packs for High-Precision Autoinjectors

At RPK Medical, we recognize the critical role of precision in autoinjectors, mainly when delivering high-viscosity medications. These devices are indispensable for emergency-use treatments and patients managing chronic conditions requiring self-administration at home.

For daily use, autoinjectors must function flawlessly at the exact moment they are needed. They must deliver the correct dose with a specific, consistent force to ensure treatment efficacy and patient safety.

RPK Medical develops and manufactures Power Packs that integrate Constant Force Springs and Power Springs, combined with precision-engineered stamped components. These solutions are designed to provide:

✅ Consistent Force Delivery – Ensuring reliable drug administration with every use.

✅ Optimized Performance – Enabling high-precision delivery of even the most complex medications, especially high-viscosity drugs.

✅ Enhanced Patient Experience – Supporting safe, efficient, and effortless self-administration.

Through our expertise in precision engineering and industrialization, we help Pharmas, CMOs, and medical device engineers develop next-generation autoinjectors that meet the highest industry standards. We aim to improve patients’ lives by making treatment easier, safer, and more reliable in their daily routines.
