DTi Study Shows 50 Percent Savings with Advanced Grommets
SOUTHBOROUGH, Mass.–Device Technologies Inc., a designer and manufacturer of wire protection, enclosure–related, and environmental protection components, released a study showing its advanced grommet edging can save time and money over an aircraft's 30–year life cycle.
The study shows that the traditional nylon grommet MS21266 is 206 percent more expensive than M22529/2 when the 30–year costs of installation, inspection, replacement, and repair are assessed. This means that M22529/2 is only 48.5 percent of the nylon grommet cost–a significant saving, the company reported in a press release.
"The use of advanced avionics in aircraft has led to a proliferation of wiring harnesses and cable assemblies," said Nick Petri, president and CEO of DTi, in a statement. "However, these advances have significantly increased the size, weight, and complexity of wiring and cable assemblies. These all need wire and cable anti–chafe protection to help ensure electronic transmissions, protect data, and preserve system integrity."
The traditional MS21266 nylon grommet is molded as a straight, stiff element, cut to length and bonded around penetrations and along edges using MEK solvent based adhesives. Installation is a multi–step, time–consuming, costly process, and it's estimated that 10 percent require in–process rework, mostly due to poor bonding and "egg–shaping" of the grommet.
DTi's M22529/2 is said to snap onto the airframe in seconds, with no VOC paste adhesive or cure time, saving 63 percent of the direct labor and material installation cost per grommet. This simple, fast, snap–on installation without adhesive means that the costs for replacement and repair–significant elements for MROs–are just 6.5 percent of the same costs for the traditional nylon grommet, the company said.
"We also have a clear edge in performance as the M22529/2 has superior fit and dimensional stability," said Petri. "The CRES steel substrate material makes our advanced grommet edging resistant to changes in temperature and moisture without degradation of its compression and retentive strength."
The company said that because the M22529/2 grommet, with its military specification, is classified as a "standard part" by the FAA, OEMs and MROs can safely and easily switch to the M22529/2. In addition, DTi can help justify the switch by providing companies with its Life Cycle Cost Analysis tool.
"We know OEMs and MROs must show a strong rationale when making changes, so along with demonstrating our ease of use and best in class performance, we also developed the LCC tool to show the enormous savings of switching to the M22529/2," said Petri. "Our staff will work with the company's team to develop an LCC analysis tailored to their unique specifications."
Device Technologies' LCC model is designed as an adaptable framework where performance parameters and cost driver attributes can be customized to meet the company's specific needs.
Device Technologies, Inc. (devicetech.com) designs and manufactures advanced protection components and materials that include grommet edgings, enclosure seals, trims, wire protection sleeving, and EMI shielding, absorber, and thermal materials. The company's products have applications in industries such as automotive, aerospace, military, transportation, energy, and telecom. They are also said to have applications in the IT, medical, gaming, HVAC, and food service industries.
DTi invests in R&D to enhance products, process improvements and cost savings for its customers. The firm is ISO 9001 and AS 9100 compliant.
"We encourage OEMs and MROs to meet with us," Petri said, "to review the research study and discuss how they might realize the benefits and enormous savings of switching."
