EWI Requesting Filter Material for N95 Mask Production

N95 FILTER MATERIAL NEEDED – EWI is actively working with a number of manufacturers to produce surgical masks in response to COVID-19 and the shortage of personal protective equipment for medical professionals. The masks can be 3D-printed immediately using EWI’s additive manufacturing capabilities and alternative materials.

We are now seeking a source for filters or filter material which is critical for the effectiveness of the N95 mask. If your organization is able to provide qualified filter material, please contact Dominic Myers at 716.710.5535 or [email protected].

Message from EWI on COVID-19

A message from Henry Cialone,
EWI President and CEO

With limited personal interaction and increasing contact restrictions due to COVID-19, we are all making adjustments to how we do business. While the environment has changed, I want to let you know that EWI remains open for business. We are actively proceeding on existing projects and working together with customers to meet your current and upcoming needs.

Most EWI associates are now working remotely thanks to our dedicated IT team, which has proactively developed a robust internal communication system over the last few years. Those who must come into the labs to work are following CDC guidelines on hygiene and social spacing.

Please note the following:
• The EWI facilities in Columbus, Buffalo, and Colorado are closed to non-staff members.
• All project work is continuing as planned.
• In-person meetings are canceled at this time.
• All EWI staff can still be reached by direct email or office phone number. For general contact, call 614.688.5152 or email [email protected].

If you need anything from EWI, please feel free to reach out to any of us. We are here to serve.

Thank you and stay safe.

Optimize Product Design and Joining Process for Your Next Product

Manufacturability is an important consideration in product
design. A great idea in prototype will not succeed if it can’t be transitioned to
mass production. All too often, however, manufacturability factors are
overlooked until late in the design process and problems arise.

One critical aspect of manufacturing is materials joining. If joining considerations are made after designs are complete and materials chosen, both costs and launch time can escalate. Evaluating joining options early in the design stage, however, can have a favorable impact on getting your product to market quickly and efficiently.

How do you determine most appropriate assembly method for your design? EWI Senior Technology Advisor James Cruz has written The EWI Guide to Design & Process Selection for Materials Joining to help you avoid expense, lost time, and headache as you move a concept through design toward production. The guide is available free of charge.

If you would like to learn more about EWI services that can help you optimize design and process selection for your new product, please contact [email protected] or 614.688.5152.

Wire DED at EWI

In-situ monitoring — seam, width, and melt pool characteristics

Wire DED (Directed Energy Deposition) processes have come a long way. Over the last 10 years, there has been a lot of interest, particularly in process parameter development and in-situ monitoring.

At EWI, Yash Bandari is monitoring and controlling every detail (like seam, melt pool, heat-input etc.) to make sure process remains stable (see pictures), and at the same time the resulting properties are acceptable. Our systems can build large scale components with deposition rates as high as 25 lbs/hr (~12 kg/hr) out of most of the materials like Ti64, Inconel 718, 625, Alloys steels, Aluminum alloys, etc. thereby reducing build time.

Evaluation of the Effect of Load on Vibration Amplitude in Ultrasonic-assisted Drilling

It is well known that variation in amplitude can affect the consistent performance of an ultrasonic system for use in industry. In ultrasonic-assisted drilling (UAD), this matter is even more critical. Due to the unavailability of the drill tip during the drilling process, it is extremely difficult to measure varying process parameters such as load on drill-tip amplitude.

EWI has developed a new method to measure the effect of load on the amplitude of a UAD system. The results could significantly improve UAD process stability and quality control. The technique is described in a paper by EWI Project Engineer Amin Moghaddas, Evaluation of the Effect of Load on Vibration Amplitude in Ultrasonic-assisted Drilling. To download the paper, simply complete the form on this page.
