Product Spotlight – EnduroSharp® Nutplate Abrasion Tool “The NAT”

January 27, 2022  |  , , ,

EnduroSharp® has changed the way aerospace maintenance professionals remove sealants and adhesives from substrates and fasteners.

Adhesively bonded nutplates are increasingly being utilized in the manufacture of aerospace structures, with extensive use in securing removable maintenance access panels.

Traditionally, aerospace maintenance professionals prepared nutplates using manual methods such as abrading files or grinders.  This proved very inefficient because the abrading was often uneven,  leading to adhesively bonded nutplate failure.  While rotary abrasion tools (RATs) where better, they were often bulky and expensive.

That’s why EnduroSharp® developed the Nutplate Abrasion Tool (NAT).   Precisely designed to work with adhesively bonded nutplates, the product consists of a aluminum upper and lower handle and 4 nutplate base inserts.  The product is packaged in a convenient, rugged case which is handy for transporting.

Performance Plastics is a custom precision injection molder of high performance, tight tolerance thermoplastic components. We specialize in geometrically complex precision parts that consist of chemically inert materials. Our expertise led to the development of our patented EnduroSharp® line of Aircraft Maintenance Tools.

Injection Molded Parts for Air Motors

January 6, 2022  |  , , , ,

The ability to mold unique and complex parts is what we do at Performance Plastics. Our engineers are constantly pushing the limits of our machines and material in order to produce complex parts. We excel when using high performance plastics for challenging applications.

Air motors produce continuous rotary power from compressed air. The vanes in the rotor cause the rotor to spin by sliding in and out when air is pushed into the rotor. The force differential created by the unbalanced force of air on the vanes causes the rotor to spin in one direction. Vanes are extremely important when it comes to how the motor performs. The torque of the motor correlates to the vane surfaces and pressure of the air. Vanes undergo a lot of friction wear and pressure, making material choice for this project challenging.

Vanes need to be made from material that have high strength, low creep, resistance to high temperatures, low friction wear and resistant to water and organic compounds. Any deformity or wear in the vane will take away from the torque of the motor. Therefore, we had to choose a high-performance plastic that will be able to handle the pressure of the compression inside the rotor without wearing or hindering the movement of the vane. The only two high performance plastic materials that fit the criteria are PEEK and Torlon®, two materials that we are experts in using at Performance Plastics. The mechanical properties in these high-performance plastics will allow for the vane effectively slide in and out of the rotor without causing damage to the vane.

Injection Molded PFA in the Lithium Ion Battery

December 17, 2021  |  , , , ,

The Lithium Ion Battery industry has begun using more and more plastic parts in their manufacturing processes. Most batteries intended for light vehicle usage now have 50% more plastic materials than they did even 10 years ago.  Some batteries have entirely plastic formulations ranging from the electrolyte (polymeric electrolytes) to the casing.  This is due to the very low weight of plastics as compared to metals. Plastic incorporation in batteries increases the electrolyte efficiency if used in polymeric electrolytes.

Commercially available lithium-ion batteries also use plastics. Plastic components incorporated in batteries include separators, gaskets, and casing components. Plastics have good shock absorbing characteristics and prevent damage to the basic cell unit from minor accidental shocks. Also, plastics such as Teflon® PFA, Ultem® PEI, and PPSU have high temperature resistance, corrosion resistance, and are electrical insulators so they are excellent at preventing short-circuit and “rapid disassembly.”

There has been a major shift from metal to resins in gasket manufacturing. Gaskets can be made from Ultem®, Ryton PPS and Fluoropolymers (PFA plastic) because of high heat resistance, chemical resistance, and ability to mold thin walls (.012”). Plastic parts may also lower the cost of production of batteries and may eventually replace most metallic components of batteries.

Performance Plastics is highly skilled at designing and molding high performance materials such as FEP/PFA, Ultem®, Torlon®, PEEK, POM, and PPS.  We work with our customers to solve technically challenging problems.   We can propose materials to implement part functionality in the design stage of development. We offer manufacturing solutions such as a clean room, the ability to offer direct gating of fluoropolymers, high volume production, visual inspection and automated facilities.

Achieve Better Bonding using the Nutplate Abrasive Tool (NAT)

October 20, 2021  |  , , ,

 

Nutplates are commonly used on aircraft to allow installation and removal of components and panels for maintenance and repair. The use of bonded nutplates over riveted ones reduces manufacturing complexity and leads to weight savings.

Preparation of these bond surfaces is often accomplished through a manual abrasion process or by using chemical solvent wipes. These methods are difficult to control and can lead to variation in the performance of bonded nutplates. Successful installation of bonded nutplates requires the generation of a highly clean and active bonding surface.

That’s why Performance Plastics in conjunction with the University of Dayton Research Institute developed the EnduroSharp® Nutplate Abrasion Tool “NAT”.   The NAT consists of six components: 1 each upper handle (top), 1 each lower handle (base) and 4 each nutplate base inserts.

An alternative to traditional abrasion methods, the “NAT” was specifically designed to allow maintainers to quickly abrade the bond surface of CR series nutplates. The tools radially abrade the bond surface of the nutplate, ensuring that 100% of the bond surface is abraded uniformly in a manner of minutes.

This new technology eliminates interfacial bond failures while increasing pushoff strength and torque-out strength when compared with manual abrasion. Furthermore, the device has been shown to reduce preparation time, decrease variability and lower the instances of nutplate failures both in manufacturing and in the aircraft service environment.

The NAT is available with or without a convenient carrying case. For more information on the Nutplate Abrasive Tool or any other Performance Plastics product, please contact Rich Reed, Vice President of Sales & Marketing for Performance Plastics at [email protected] or call 440-785-7122.
