Used Kawaguchi Equipment Sold by Meadoworks

Kawaguchi was established in Japan in 1944 by founder Koji Kawaguchi and grew into one of the country's most influential injection molding machine manufacturers. At its peak the company commanded roughly 30 percent of the Japanese market and claimed several industry firsts, including Japan's first low-pressure foam injection press, the introduction of robotic arms on injection molding lines, and the first use of external storage devices on injection molding equipment. That legacy of innovation established Kawaguchi as a benchmark name in plastics processing machinery.

The company's core product line has always been horizontal hydraulic injection molding machines, and the KM-B series became its most widely recognized family, covering clamping forces from compact sub-100-ton machines up through large-frame 650-ton and heavier configurations. The KS-B series addressed smaller-tonnage applications where a tighter footprint and lower shot sizes were priorities. Later generations, including the KM-B2 refinements seen in mid-1990s production, brought improved hydraulic efficiency, more rigid clamping structures, and enhanced injection control while retaining the straightforward, serviceable architecture that operators valued.

Kawaguchi injection molding machines found wide adoption across thermoplastics processing industries including consumer goods, automotive components, electronics housings, packaging, and medical device manufacturing. Their broad tonnage range made them equally at home producing small precision parts and large structural components, and their compatibility with a wide variety of engineering-grade resins gave processors the flexibility to take on diverse work with a single platform.

Used Kawaguchi injection molding machines remain in strong demand because the KM-B and KS-B platforms were built to exceptionally tight Japanese manufacturing tolerances and have demonstrated the ability to hold consistent shot weights and clamp forces well into their second and third decades of service. Replacement wear parts such as screws, barrels, and hydraulic components are widely available through the global used-parts market, keeping maintenance costs manageable. Buyers seeking a reliable, proven hydraulic horizontal press at a fraction of new-machine pricing consistently turn to Kawaguchi as a cost-effective path to production capacity.
