This approach not only enhances products’ durability and safety, but also aligns with the brand’s goal to provide cutting-edge solutions.
Engineering Excellence in Medical Grade Plastic Casing
Esther shares her experiences, highlighting the collaborative journey with the Alcami team: “They were instrumental in devising the most effective engineering strategies to address the main obstacles we faced with our product designs,” Esther remarks. She then delves into the specifics of the engineering.
Durability and Water Resistance
The team was tasked with a complex challenge. The product, a sensor designed for use during physical activities, required a robust and water-resistant design. Achieving this was particularly demanding given the compact size of the device. Moreover, the necessity for exposed metal conductive elements, which are crucial for the device’s charging capability, added an extra layer of complexity.
Optimized Plastic Injection Molding Solutions
To navigate these challenges, the Alcami Global team suggested an innovative approach—over-molding the metal insert pin for charger connectivity. This technique ingeniously encased the metal conductive element, ensuring the device remained waterproof. At the same time, it kept the charging pin accessible, maintaining its functionality.
Innovative Sealing Solutions for Irregular Shapes
Esther illuminated another significant hurdle—achieving a watertight seal for the device’s uniquely shaped casing, which is a pivotal aspect of their brand identity. The irregular form factor rendered standard sealing solutions, like o-rings, ineffective. “This was a major concern, as it directly impacted the feasibility of mass production,” Esther explained. The Alcami team engineered a solution: an over-molded TPE (thermoplastic elastomer) seal integrated directly onto the sensor casing components. This method not only circumvented the need for conventional o-rings but also enhanced the device’s design integrity and water resistance.
Alcami's Support to Engineering and Manufacturing

According to Esther, Alcami played a pivotal role in her project’s success by providing innovative manufacturing solutions and robust support. One key aspect was the access Alcami afforded Esther to their clean rooms and heat chambers, which were both essential for testing the sensor-based electronics in the products under varying environmental conditions..
Rapid Prototyping and In-House Tooling Capabilities
The necessity for rapid iteration in product development is a challenge that many technology companies face. Alcami Global addresses this issue with its own in-house rapid prototyping capabilities, including 3D printing and CNC milling. This allows for quicker feedback cycles and adjustments in product design, significantly reducing the time and cost associated with external sample production and validation.
The Importance of Trust and Ethical Practices
The importance of trust and integrity in manufacturing cannot be overstated, especially when it comes to protecting intellectual property and ensuring scalable production capacities. Esther notes the positive impact of Mr. Withouck’s leadership on Alcami Global’s culture, and how that gave her the necessary confidence to trust the company with her project. This aspect of trustworthiness and ethical conduct is essential for long-term partnerships and successful project outcomes.
