Precision in medical sealing: The Development of Okapi
In 2021, Resivant Medical turned to ENBI Plastics & Silicones to develop two silicone components for their Cutiva™ PLUS Skin Closure System. Designed to support faster and more hygienic wound healing, this solution combines medical-grade silicone with advanced adhesive technology. The project marked a key step in further refining ENBI’s expertise in molding Liquid Silicone Rubber (LSR). With a fully electric production line and the required medical certifications, we committed to meeting the sector’s highest standards.
Our workflow in practice
From the start, the Okapi followed our structured development approach. Together with Resivant Medical, we defined the product specifications and conducted feasibility studies. During this pre-engineering phase, we focused on material selection, molding techniques and validating the concept. Our engineering team explored how to apply LSR molding effectively, testing different methods for optimal performance.
A precise production challenge
One of the key challenges in this project was the geometry of the pen’s tip, which required flawless contact with the skin. To achieve this, the molding process had to avoid even the slightest film formation.
Equally critical was the airtight seal within the device. A tiny silicone ring ensures proper sealing and precise glue distribution. Producing this component required extreme control, with a shot weight of less than 0.1 grams per cycle. Pushing the limits of LSR precision molding.
Throughout the process, all production steps were carried out under ISO 13485 conditions. That meant full traceability, a highly controlled environment and a quality system capable of guaranteeing consistent results.
A smart product with real-world impact
By combining engineering precision with deep material knowledge, we delivered a silicone solution that improves surgical outcomes. The Okapi case demonstrates the strength of collaboration and ENBI’s commitment to solving technical challenges with clean execution and certified quality.
It was a valuable project that advanced our experience with LSR molding in a medical setting, resulting in a reliable product that performs under the strictest requirements.
Unseen, yet essential!
