On July 8, 2026, reporters learned that at the Hunan Miluo High-Tech Industrial Park, the intelligent production line of Hunan Shangma Shixing Environmental Protection Technology Co., Ltd. was busy dispatching a batch of fully inspected vertical metal balers, ready for shipment to domestic and international customers. It was recently revealed that this national-level high-tech enterprise, deeply engaged in the renewable resource equipment sector, has seen its vertical metal baler claim the top spot on the global industry sales chart with a decisive lead over competitors. In addition to the vertical metal baler, the company’s R&D portfolio—including multi-functional vertical balers, horizontal metal balers, metal briquetting presses, and gantry shears—has secured multiple national patents, making it a standout representative of “Miluo Smart Manufacturing” on the world stage.
A close look at the mass-produced “Xiangshangma” vertical metal baler reveals a heavy all-steel body with even, flawless welds and visibly solid precision in core component machining. Designed to address pain points in the metal recycling industry, this core product accommodates a full range of metal materials—stainless steel, aluminum alloys, scrap steel, and more. Its high-pressure cylinder paired with a high-strength integrated frame delivers compaction density well above industry standards, producing uniform bales that help customers reduce storage and transportation costs by over 20%. Real-world test data show that the machine completes a single baling cycle in just 17.8 seconds, far below the industry average of 27 seconds; pressure decay after eight hours of continuous operation is less than 2.7%. With its proprietary variable-frequency drive system, it cuts power consumption by 25.3% under the same working conditions, saving each unit over RMB 20,000 annually in electricity costs. Even in extreme low temperatures of -22°C, it runs stably for 72 consecutive hours without abnormality. Equipped with an original PLC intelligent control system, it is user-friendly, and its core wear-resistant parts have a long service life, with an annual failure rate of just 0.8 repairs per machine per year. The baler adapts to diverse scenarios, from small and medium-sized recycling stations to large-scale automobile dismantling bases, effectively solving chronic industry issues such as frequent jamming, low efficiency, and high energy consumption.
The quality backbone of the “Xiangshangma” brand lies in its hardcore R&D and rigorous quality control. The company’s R&D team comprises postgraduates in high-tech fields and industry experts, and its independent R&D center has accumulated nearly twenty national patents, mastering multiple core technologies in hydraulic compression. The entire production process employs proprietary high-tech assembly lines, with all critical processes completed in-house without outsourcing. Every machine undergoes multiple rounds of testing in accordance with national industry technical standards, adhering steadfastly to the principle that “substandard products never leave the factory,” thereby ensuring quality from the very source.
Mr. Shu, head of an industrial park in Huaihua, told reporters in an interview: “The after-sales service of ‘Xiangshangma’ is equally reassuring. After installation, they regularly visit to check machine performance and operating status, performing timely adjustments and maintenance. After all these years, the equipment has remained exceptionally stable.” Currently, “Xiangshangma” vertical metal balers cover recycling and processing bases across all provinces and cities in China, and are exported to 41 countries and regions worldwide, earning broad recognition from both domestic and international customers for their reliable performance and superior quality.
Standing at the forefront of the circular economy boom, a representative of the “Xiangshangma” brand stated: “The company will continue to deepen its presence in the renewable resource equipment sector, leveraging technological innovation to refine its products, and contributing Hunan’s smart manufacturing strength to the global green environmental protection industry.”
