Marks HUHUTECH's Evolution from Facility Engineering Firm to Integrated Solutions Provider

WUXI, China, June 08, 2026 (GLOBE NEWSWIRE) -- HUHUTECH International Group Inc. (NASDAQ:HUHU) ("HUHUTECH" or the "Company"), a global provider of high-purity process systems and factory facility management and monitoring solutions for semiconductor manufacturers and industrial clients, today announced that its subsidiary, Jiangsu HUHU Electromechanical Technology Co., Ltd., has completed the fully independent development and technology finalization of the HB-800, a high-end vacuum furnace designed for MOCVD (Metal-Organic Chemical Vapor Deposition) susceptor cleaning and precision heat treatment applications. The milestone marks HUHUTECH's evolution from a facility engineering and services provider to an integrated solutions provider with proprietary in-house equipment, broadening its role with semiconductor and advanced-manufacturing customers.

This integrated "engineering support, proprietary equipment, and equipment retrofit" platform deepens the Company's relationships with high-end manufacturing customers and positions HUHUTECH to participate in the growing trend toward domestic substitution of precision equipment in its core markets.

"The HB-800 is a significantmilestone for HUHUTECH, representing our first fully self-developed high-end precision equipment platform and the foundation of a new growth engine beyond our engineering-services roots," said Mr. Yujun Xiao, Chief Executive Officer of HUHUTECH. "By combining our facility engineering heritage with proprietary equipment and retrofit capabilities, we are deepening our position across the semiconductor manufacturing value chain and opening a new, higher-value avenue for long-term growth."

The HB-800 is designed to serve five end-markets: semiconductors, photovoltaics, third-generation semiconductor materials such as silicon carbide (SiC) and gallium nitride (GaN), aerospace precision manufacturing, and medical precision components. The furnace targets recurring-demand applications, including precision heat treatment, MOCVD susceptor and carrier-tray cleaning, and upgrades to customers' existing installed equipment.

Based on internal testing benchmarked against conventional equipment, HUHUTECH expects the HB-800 to deliver higher resource recovery rates, lower energy consumption, longer maintenance interval cycles, and stable mass-production performance, which the Company believes may help customers reduce raw material, electricity, and maintenance costs. The Company intends to pursue a dual commercial model of new equipment sales alongside upgrade-and-retrofit services for existing installed equipment, which it believes may offer a differentiated, lower-cost path for customers to modernize aging equipment.

The HB-800 has completed design finalization and verification testing and is ready for commercial deployment. Drawing on its existing customer relationships, HUHUTECH is engaged in business development discussions and currently expects to sign its first equipment order during the third quarter of 2026. Over the longer term, the Company intends to scale production capability and pursue broader market adoption as it builds out the new equipment business line, which it expects to carry attractive margins relative to its established engineering-services business.
