Sunzone

What Sunzone does

Shenzhen Sunzone Electrical Appliances Ltd. (深圳市顺章电器有限公司) is a Chinese OEM/ODM manufacturer founded in 1994 as a subsidiary of Jinke Special Materials Group, which itself was founded in 1987 as a subsidiary of the Chinese Academy of Sciences. The company specializes in PTC (Positive Temperature Coefficient) ceramic heating technology and PCBA (Printed Circuit Board Assembly) control systems, operating a vertically integrated stack that ranges from raw PTC heating elements and PCBA circuit boards to finished consumer appliances. Finished-goods categories include PTC ceramic fan heaters (25+ models, 1500-2200W), evaporative air coolers, electronic humidifiers, and bladeless/aroma diffuser fans; component categories span PTC elements for kitchen appliances, beauty products, home appliances, battery insulation, water heating, and new energy vehicles, plus PCBA boards for home appliances, fascia guns, LED lighting, bathroom products, air coolers, ceramic heaters, and purifiers. Production sits across two Shenzhen facilities (headquarters at Longhua and Shenshan Special Cooperation Zone), a 3,200 m² Thailand factory established May 2024, and a 25,000 m² production base with 5 semi-automatic lines, 29 injection machines, and stated monthly capacity above 200,000 units and annual capacity of 2 million PTC heaters.

SUNZONE generates revenue primarily through B2B OEM manufacturing — producing finished appliances under customer brand labels such as DeLonghi, Honeywell (a 28-year partner), Lasko, Dimplex, Sanyo, and EWT — and ODM custom design and development services spanning R&D, industrial design, prototyping, tooling, certification, testing, pilot runs, and mass production. A secondary component business sells PTC heating elements and PCBA boards directly to other manufacturers. Finished goods reach end consumers via customer distribution networks including Walmart, Target, Lowes, Amazon, and Carrefour/Sam's; SUNZONE also operates Alibaba and 1688 storefronts for smaller buyers and international traders. Pricing is quote-based on bulk B2B orders with no retail pricing publicly disclosed. The company holds ISO9001, ISO14001, TS16949 (automotive), and BSCI (annual) certifications, and its products carry 3C, ETL, CETL, GS, CE, UL, TUV, and CQC marks, with patented structure designs audited by Walmart, Carrefour, Sam's, Target, Amazon, and Lowes.

The company's customer base is anchored on a small roster of large global brand partners, creating moderate concentration risk, while its recent strategic moves — Thailand factory establishment, NEV PTC heater commercialization, and PCBA platform extension into new verticals — point to active diversification beyond traditional consumer-appliance OEM. Geographic reach spans the US, Japan, South Korea, UK, Australia, South Africa, the Middle East, the EU, and (newly) Southeast Asia via the Thailand subsidiary, with cumulative production exceeding 23 million units over its operating history.
