Ishigaki USA

What Ishigaki USA does

Ishigaki USA is the North American subsidiary of Japanese parent Ishigaki Company, Ltd., headquartered in Portsmouth, New Hampshire, and serves B2B customers in mining and metals, municipal and industrial wastewater treatment, and general industrial and environmental sectors. The entity's functional role within the group is primarily regional sales, customer engagement, and after-market support for solid-liquid separation equipment, with manufacturing handled by the parent and affiliated entities (including Ishigaki Global Supply Ltd. in Thailand).

The company's core product portfolio comprises five industrial filtration and separation lines: the LASTA MC and LASTA SD filter presses for solid-liquid separation and dewatering; the ISGK-A screw press for mechanical sludge dewatering; the Tumbling Thickener for sludge concentration upstream of dewatering; and the Polishing Filter IFW for final-stage liquid purification. These offerings are positioned under the 'Designed to Filter, Engineered for Life' engineering philosophy and target applications such as mineral processing, tailings management, sludge thickening/dewatering, water recycling, effluent treatment, and high-purity water output.

Ishigaki USA operates an enterprise, direct-field sales motion — pricing is not publicly disclosed and is engaged through an 'Inquire Now' contact path via phone and email — with revenue generated from one-time equipment sales and, by implication from the parent's online parts catalog, aftermarket spares. Marketing is conducted through a professional B2B website featuring product detail and application pages, supplemented by an email newsletter. Within the broader Ishigaki group, Ishigaki USA is one node in a network spanning Japan (Tokyo HQ), China (Suzhou/Shanghai), Thailand (Bangkok FTZ — parts manufacturing), Australia (Malaga), Germany (Nürnberg), and Turkey (Ankara).
