Used Matsui Mold Temperature Controllers for Sale

Matsui Mfg. Co., Ltd. was founded in Osaka, Japan in 1912 by Miichiro Matsui, initially producing medical and scientific instruments. In 1962 the company pivoted decisively into the plastics industry, developing a temperature-adjustable plastic dryer that was far more accurate than anything else available at the time. That innovation established Matsui as a plastics auxiliary equipment specialist, and the company expanded globally, opening its first U.S. office in the Chicago area in 1986. Today Matsui operates from its Osaka headquarters with subsidiaries, sales offices, and distribution partners across North America, Europe, and Asia.

Matsui's two flagship product lines are resin dryers and mold temperature controllers. The DMZ series of portable desiccant dehumidifying dryers uses Matsui's proprietary honeycomb desiccant rotor technology to maintain a stable dew point of -40°F, bringing moisture content below 50 ppm and drying hygroscopic resins such as PET, nylon, and PBT in a fraction of the time required by conventional twin-tower systems. The GMC and MCN series water temperature controllers deliver precise mold temperature regulation for standard and elevated water temperatures, while the broader MC series has accumulated a track record of more than 157,000 installed units worldwide. Matsui also manufactures granulators, vacuum loaders, and gravimetric blenders as part of a complete auxiliary equipment offering.

Matsui auxiliary equipment serves processors across injection molding, blow molding, and extrusion in industries including automotive components, electrical and electronic parts, medical devices and optical components, rigid packaging, PET preforms and bottles, and consumer goods. The company's energy-conservation philosophy, branded as its Factor 4 initiative, is particularly valued in high-volume production environments where cycle time, resin quality, and energy cost are critical.

Buyers seeking used Matsui dryers and water temperature controllers consistently cite the equipment's robust build quality, long service life, and the continued availability of genuine replacement parts through Matsui America's online parts store. Matsui's desiccant rotor wheels are engineered to hold dewpoints to specification for 15 years or more, meaning well-maintained used DMZ and GMC units retain strong processing performance long after their original purchase. The compact footprint and straightforward controls of Matsui machines also reduce retraining time when integrating pre-owned units into existing production cells.
