Design Assistance

 

Jonal takes a team approach to problem solving your design requirements.  We assemble our engineers, chemists, and technical and manufacturing staff all operating under our quality guidelines. They will discuss your requirements so that a solution can be achieved which is both cost effective and meets your requirements.  We find extra care and attention upfront is much more successful than trying to re-engineer later in the process.

Jonal molds complex shapes that incorporate a variety of fabric reinforcements and metallic inserts.  Products include: diaphragms for pressure regulating and fuel control; accumulators for hydraulic systems; aerodynamic and environmental seals with special properties such as flame retardance, wear resistance, electrical conductivity and high strength under centrifugal loads. Jonal can bond a variety of elastomers to metallic and non-metallic substrates, including aluminum, stainless steel, titanium, plastics and composites. We assist in the design and co-ordinate the manufacture of all tooling necessary for your application. Most importantly, we can provide samples and prototypes with a fast turnaround and competitive cost.

Jonal provides engineering services, and has been working with customers to develop new and unique aeronautical and aerospace products since 1965. Some of our accomplishments are as follows:

  • Developed and sole source provider of custom polyurethane foam parts that control airflow in the compressor stages of large turbofan engine such as the Pratt and Whitney 4000 and JT-9D series.
  • Assisted in the design and development of the elastomeric gearshift boot for the Abrams A-1 tank.
  • Poppet valve seals employed in spacesuits for Hamilton Sundstrand.
  • Supply various sophisticated molded components for Raytheon, Honeywell, Goodrich, Hughes and other defense contractors for demanding applications such as the AMRAAM, Sidewinder, Sparrow, Hawk, and Patriot missiles. Jonal supplies specialty O-rings to Parker Hannifin.
  • Developed an oil tube and electrical conduit tube installation and mounting system for the Pratt TF33 engine.
  • Instrumental in the design and development of critical components for the Common Missile Warning System program (CMWS), involving precision molding, and EMI shielding for BAE Systems Nashua NH divisionsí Joint Military CMWS program. Jonal received a letter of commendation from the program manager for outstanding performance.
  • Developed extreme high temperature resistant silicones, reinforced and unreinforced with fiberglass to AMS-3352 and PWA-36453 specifications.
  • Assisted in the design and developed high strength, high temperature resistant, reinforced and unreinforced silicone with fiberglass or nomex for Hamilton Sundstrand flexible connector boot application.
  • Fabricated a complex fluorocarbon elastomer bladder for the N.A.S.A. space suit.
