THE CHALLENGE: Manufacturing a High-Precision Core Plate

To bring the Cadence Tablet to market, Tactile Engineering needed a manufacturing partner with deep expertise in metal injection molding for medical devices. The core plate required:

  • Exceptional flatness and dimensional stability

  • Non-magnetic properties

  • Tight tolerances

  • Material consistency at scale

These characteristics ruled out conventional machining and casting methods. Tactile Engineering turned to MPP’s advanced MIM capabilities for a scalable, repeatable solution.

THE CHALLENGE

Tactile Engineering approached MPP seeking a solution for producing the Core Plate for their Cadence Tablet, a dynamic braille reader for the blind and visually impaired. The product had specifications (precise, flatness, and non-magnetic characteristics, etc.) that required a new approach to Metal Injection Molding manufacturing MPP was ready to take on.

THE SOLUTION

MPP collaborated closely with Tactile Engineering to design and produce the core plate using 17-4 PH stainless steel, in compliance with MPIF Standard 35. By leveraging proprietary MIM feedstock formulations and process control, MPP delivered:

 

  • Consistent part geometry and flatness

  • Controlled magnetic permeability

  • Repeatable part quality at high volumes

  • Full traceability and materials compliance for medical device standards

This approach enabled complex geometries and tight tolerances while maintaining the performance and regulatory requirements of a high-tech medical device.

THE IMPACT
For our customer:

The transition from traditional manufacturing methods to MIM technology resulted in a significant reduction of 40% in waste and 10X in cost savings per piece for Tactile Engineering. Additionally, the solution simplified manufacturing and enhanced efficiency in their assembly process.

 

For the market:

The Cadence Tablet revolutionizes accessibility for the blind and visually impaired, making it the first tactile device to display tactile graphics that move and change beneath a user’s fingers. This device opens opportunities for individuals with disabilities to interact and experience live events, entertainment, and access dynamic content, textbooks, and collaborative tools. The Cadence Tablet reduces accommodation costs, enhances educational and professional opportunities, and improves quality of life for an underserved population.
