DIY Testing the Effectiveness of Sound Absorbing Materials

sound absorption testing

In this post, we're going to try something different. Rather than sending different materials off to test their impact on sound absorption, we're going to develop a decibel meter test in-house that anyone could do.  We're going to take you through this step-by-step.  This may be a rough test, but if you start if you begin noticing an obvious difference in sound reduction between two materials, chances are you're probably on to something.

The Engineering & Manufacturing Complexities of Injection Molding Automotive Barbed Hose Connectors

Manufacturing barbed hose connectors

The burden of fluid connector part design and design for manufacturability has shifted from the OEM to the tier-1 supplier and their injection molding partner.  Throughout this post, we’ll discuss what makes an injection-molded barbed connector technically complex, critical design elements that need to be factored in, and the molding expertise required to deliver a stable and repeatable part.
