About Jonal

Jonal provides single-source responsibility for elastomers, molded rubber, metal-bonded and composite materials.  We manufacture to order.  We provide responsive service.  We deliver on schedule and can provide extremely fast turnaround of samples and prototypes. 

Applied Resources...

Jonal is results-oriented.  We apply three essential ingredients to every compound we formulate and every product we manufacture, from concept to prototype.

The first is over four decades of experience meeting AMS, ASTM, Mil-Specifications and the most demanding company proprietary specifications.

The second is technology.  The most versatile and cost-efficient manufacturing techniques enable Jonal to respond on time and within budget.  Highly advanced production and machinery ensures consistency and scheduled delivery.

The third is a commitment that our elastomer products meet or exceed our customer's expectations for performance.  Strict quality control procedures include:

  • ISO-9001/AS-9100
  • Incoming Material Testing & Inspection
  • Process Controls
  • In-process Inspection
  • Continuous Product Testing
  • Final Inspection

Our facilities in Meriden, Connecticut encompass nearly 40,000 square feet of Research and Development and manufacturing facilities.  Our technical staff of Engineers, Technical Director, Chemists, and Technicians together with 75 skilled employees are focused on solving problems of environmental sealing, vibration damping and electromagnetic interference.  We can make a difference in the success of your products, components and systems.
