Basics of Rubber Compression Molding Tools

rubber compression molding basics

Compression molding is an excellent, cost-effective manufacturing method for making a variety of rubber products. But, as of right now, to get professional rubber products that meet specific requirements, visually, dimensionally, and performance-wise, then you need to understand the backbone of the molding operations... tooling.

In this post, we go over the basics of a compression molding tool for rubber components, how they're made, and what makes a tool more efficient

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.
