Precision for Progress: How Keetronics Uses Memmert Technology for Reliable Input Device Manufacturing

From smart switches to medical interfaces – Keetronics powers human-machine communication

As one of India's oldest and fastest-growing manufacturers of advanced input systems, Keetronics India Private Limited develops and produces high-performance solutions that enable human-machine interaction. Whether used in medical devices, industrial controls or public infrastructure, Keetronics products such as membrane keyboards, custom touch interfaces and smart switches must meet the highest standards in precision and durability.
With customers across Europe, South East Asia and USA, reliability and quality are key.

The challenge: curing and bonding without compromise

During production, every membrane keyboard undergoes 100 percent testing to ensure it meets Keetronics’ strict quality parameters. Two critical steps in the process involve:

  • Curing conductive inks like silver, graphite and carbon on ultra-thin films (around 125 micrometres thick)
  • Optical bonding of displays and touchscreens in a cleanroom environment, where humidity must be carefully controlled

For both applications, absolute temperature accuracy and uniformity are essential. Even minimal deviation can lead to deformation or performance issues – especially with such thin and delicate layers.

The solution: Memmert ovens for precision and consistency

Keetronics uses Memmert universal ovens at both of its production sites. The ovens are crucial to achieving reliable results in:

  • Curing conductive inks with high temperature stability, ensuring perfect layer quality without warping
  • Drying LCDs before optical bonding, effectively removing moisture in a cleanroom-compatible process

“One of the key advantages of the Memmert ovens is the high precision. Our films are very thin, and we see absolutely no deformation. We’re very satisfied with the results.”
Mr Rajesh Kulkarni, Managing Director at Keetronics (India) Pvt Ltd.

In addition to technical performance, support from the Memmert team during trials and setup was another reason why Keetronics continues to trust Memmert. The service and product reliability have proven themselves day after day.

The result: consistent quality and global competitiveness

With Memmert, Keetronics ensures a repeatable, reliable process that supports the company’s growth in demanding international markets. The ovens help secure long-term performance and product integrity – from everyday household switches to mission-critical medical interfaces.
