Carter Bros

Carter Bros Ltd – Engineers for the World’s Polymer Industry Carter Bros Ltd specialises in the manufacture of new and rebuilt internal mixers, ranging from compact 1.5-litre laboratory units to large-scale 620-litre production machines. We design and build both tangential and intermeshing mixers, delivering solutions for customers across the global rubber and plastics industry. Our heritage dates back to 1873, when the original Carter Brothers established their business as millwrights, supplying transmission and line shafting to the thriving Lancashire cotton industry. With the gradual decline of cotton, diversification became essential. In 1954, the company entered a new chapter when it was acquired by brothers John and David Bridge, shortly after their Castleton-based business, David Bridge & Company Ltd, became a public company. Since then, Carter Bros has continually evolved to meet the demands of modern manufacturing. Drawing on decades of engineering expertise, we have developed a reputation for high-performance, durable mixers that combine traditional craftsmanship with the latest technology. Today, our machines are trusted by manufacturers of all sizes around the world, from small specialist operations to leading multinational producers. Our mission remains the same as it has for generations: to engineer reliable, efficient, and innovative mixing solutions — keeping the heart of the mixing room beating strong.
