From thermal-management R&D to precision molded components to finished-goods assembly — one chain, one closed-loop system.
The products on this page come from the portfolio of Guangdong Willing Technology Co., Ltd. (NSE: 839085). Willing holds a 30% strategic stake in Hesheng as our group parent and long-term customer — group finished goods are assembled by the Willing manufacturing system, while Hesheng delivers the precision molded components, mold development, and structural solutions behind them.
In other words: every finished product you see here relies on the plastic structural parts, injection molds, and lean production systems that are Hesheng's daily work.
Willing Technology: founded 2008, national high-tech enterprise, Guangdong Specialized & Sophisticated SME. Products sold in 100+ countries, 800+ clients, annual revenue over RMB 500M.
Built on Willing's two decades of thermal/cooling management technology: heating lines for efficiency, cooling lines for quiet operation. Hesheng molds the housings and structural parts for the full series.

High-speed digital motor, constant-temperature care, lightweight body. A showcase of precision personal-care molding — ergonomic grip and air duct molded as one.

Superconductive heating, efficient and energy-saving. The ultra-slim body demands extreme flatness and heat resistance from structural parts.

Independent dual-zone control, foldable storage. Hinge and structural fit precision directly determines product life.

Fully automatic frozen desserts, multi-mode touch control — a flagship of home cooling-management technology.

Slush, smoothie, iced drinks in one machine, quiet cooling system. Transparent window parts and housing molded in-house.
Smart laminators (~30% global share), vacuum sealers, foldable warming trays, superconductive stoves, ceramic cookers, portable air conditioners, handheld ACs, cooling cups… 80+ new SKUs a year across the group.
Where Willing started: bringing thermal management into the office laminator niche — near 30% global share in the home segment. Metal-plastic hybrid structures are typical of this category.

All-metal body, laser-calibrated cutting lines, built for heavy office use. The metal-plastic assembly structure relies on molded parts.
In 2010 Willing brought thermal management into office laminators — near 30% global share in the home segment. Heat-resistant molded parts (housings, paper guides, gear sets) around the heating assembly are Hesheng's mature volume parts.
Component supply for the soonye office brand: desk organization, filing, binding consumables in continuous volume production — up to 32-cavity molds to drive unit cost down.
Behind every finished product above are molded parts like these. This is Hesheng's daily work: developing and producing precision injection parts for the group and industry clients.

Housings, brackets, and drive parts in multi-material combinations with tight-tolerance fit. One-stop from DFM and mold design to volume delivery.
Engine bay parts, medical devices, connector and sensor components. IATF 16949 controlled, 0.5g-1000g full spectrum.
50+ new molds monthly, ≥92% first-trial success rate, ≤3 trials to mass production. DFM report within 24 hours.
The Willing group runs 30 modern assembly lines with 30M units annual capacity, plus a protective-packaging line of 40+ high-speed film-blowing and bag-making machines (30,000 tonnes/year). ERP, MES, WMS, SRM, PLM, and BI run from R&D to delivery.
Hesheng's AI-MES smart molding system is the molding hub of this network: 78 machines running unmanned, feeding JIT molded parts straight to the assembly lines. Big or small, ten thousand or hundred million — one system delivers.
