As the National Day and Mid-Autumn Festival converge as scheduled in 2025, we are greeted by the beautiful encounter of "China Red" and the "Mid-Autumn Moon". On the occasion of the 76th anniversary of the founding of the People's Republic of China and the arrival of the Mid-Autumn Festival, Longhua proudly presents China's first set of new energy AI die-casting machines to celebrate the double festivals! As the developer of China's "Group Standard for Artificial Cold-Chamber Intelligent Die-Casting Machines (Certificate No.: T/CASME 1608-2024)", we have joined hands with the scientific research teams of China's "major universities and research institutes" to tackle core technological challenges. We have launched this high-performance equipment that can "turn waste into treasure" and seize the global "trillion-yuan market" through "domestic substitution". With our industry-leading technological strength, we add glory to the 76th anniversary of our motherland and inject industrial vitality into the Mid-Autumn family reunion! 1. Revolutionary "Waste-to-Treasure" Technology The most striking technological breakthrough of this equipment lies in its subversion of traditional raw material logic: it directly converts industrial wastes such as waste aluminum, waste copper, waste magnesium, and waste zinc into qualified die-cast products, realizing a circular economy model of "turning waste into treasure". This technological achievement embodies Longhua's sense of responsibility and commitment to the motherland: For the country: It reduces reliance on imported raw ores, saves a large amount of foreign exchange, and at the same time avoids energy consumption and pollution caused by raw ore mining and processing. It aligns with the "dual carbon" strategy through green technology and contributes to the motherland's ecological construction. For enterprises: It helps customers significantly reduce raw material costs and achieve more efficient production during the peak seasons of Mid-Autumn Festival and National Day. By empowering partners with technology, we celebrate the double festivals together and seek common development. 2. Five Core Technological Advantages From efficiency to precision, from quality to appearance, every technical parameter of this equipment is a "high-strength answer sheet" dedicated to the double festivals. High efficiency: Fully automated intelligent production enables 24/7 non-stop operation, with hundreds to thousands of alloy products die-cast every day, celebrating the festivals with "China Speed". High precision: With a tolerance control of ±0.1mm, it reduces subsequent processing, demonstrating strength with "China Precision". Strong adaptability: It can easily form complex structures such as thin-walled and porous parts, meeting diverse needs. High quality: It features a high yield rate and is free from defects such as sand holes and bubbles, winning trust with reliable quality. Excellent appearance: The one-time molding proces...

Warm congratulations: The total import and export volume of Bengbu City in the first half of the year reached 7.96 billion yuan, ranking 8th in the province and 1st in northern Anhui. In the first half of 2025, the total value of goods trade imports and exports of Bengbu City amounted to 7.96 billion yuan (among which, imports and exports of private enterprises reached 7.01 billion yuan, a year-on-year increase of 21.5%, becoming the main force). It ranked 8th in the province and 1st in northern Anhui in terms of total volume; with a year-on-year growth of 7.6%, its growth rate ranked 7th in the province. Specifically, exports stood at 4.93 billion yuan, up 2.4% year-on-year; imports reached 3.03 billion yuan, a year-on-year increase of 17.3%; and mechanical and electrical products grew by 20.8% (which confirms that Bengbu, the "key industrial town", is set to rise again). Bengbu's foreign trade performance in the first half of 2025 can be regarded as a model of "simultaneous growth in both quantity and quality"! The value of these figures goes far beyond the surface numbers, backed by the "dual-drive" of the government's precise services and enterprises' strenuous efforts to break through difficulties. 1. "Private Sector Strength" Takes the Lead Vigorously: Private enterprises achieved imports and exports of 7.01 billion yuan (accounting for 88.1%), with a surging year-on-year growth of 21.5%**——This is not only the main force but also an outbreak of new productive forces! It indicates that the international competitiveness of Bengbu's private enterprises is leaping from "small and scattered" to "specialized, sophisticated, distinctive, and novel", and the government has achieved remarkable results in cultivating endogenous driving forces. 2. "Mechanical and Electrical Manufacturing" Upgrades Its Momentum: Mechanical and electrical products grew by 20.8% (far exceeding the overall growth rate), which confirms the strategic success of Bengbu, the "industrial hub", in rising again and transforming from traditional manufacturing to advanced high-end manufacturing and high-value-added exports. Mechanical and electrical products have become a growth engine, laying a cornerstone for the optimization of the future foreign trade structure. 3. "Government Services": Systematic Innovation from "Blood Transfusion" to "Blood Production": Bengbu International Chamber of Commerce——The "super hub" of an open economy (established on March 5, 2025) "One-stop Service Station" for enterprise internationalization: providing full-chain services such as certification, legal affairs, and financing to lower the threshold for going global. Embracer of national strategies: integrating into top-level designs such as the "Belt and Road Initiative" and RCEP to help enterprises seize policy dividends. Magnet for foreign capital: attracting overseas capital and technology to settle in Bengbu through the network of the International Chamber of Commerce, "promoting investment t...

"From one victory to another!" Published in the Bengbu Daily on April 30, 1958—67 years ago! —Premier Zhou Enlai inscribed his congratulations to "Bengbu Machinery Factory" (Longhua). Longhua has transitioned from a planned economy to a market economy! Longhua has expanded from domestic sales to global marketing! Bengbu Longhua's Former Names: Bengbu Machinery Factory / Anhui Water Conservancy Machinery Factory (One of Anhui's "Five Major Machinery Factories")! Longhua was established on July 1, 1950, initially named the Machinery Brigade of the Huai River Control Commission. Its predecessor was the office site of the Nationalist Government's Huai River Conservancy Commission before liberation. In 1949, the site consisted only of a few dilapidated old workshops and a two-story office building. Later, the Maintenance Brigade of the National Huai River Control Commission was stationed there, then known as the Machinery Brigade of the Huai River Control Commission. On June 2, 1953, it was renamed: Machinery Repair Factory of the Huai River Control Commission. On January 10, 1958, it was officially renamed: Bengbu Machinery Factory (Anhui Water Conservancy Machinery Factory) / State-Owned. On April 30, 1958, Premier Zhou Enlai listened to a report from Bengbu Machinery Factory (Anhui Water Conservancy Machinery Factory) / State-Owned:The factory successfully passed the inspection by the National Ministry of Machinery for large-scale components such as "Gate Hoists" and "5-Meter Vertical Drilling Machines" produced for Vietnam. The project has successfully passed the acceptance inspection, and Premier Zhou Enlai praised the factory's workers in the "Bengbu Daily", saying: "From one victory to another!" On May 18, 1972, it was officially renamed Bengbu Water Pump Factory / State-Owned, mainly producing various water pumps and oil drums. Among them, the 2.8-meter axial-flow pump was applied to water conservancy projects on the Yangtze River. On July 17, 1982, it was officially renamed Bengbu Longhua Machinery Factory / State-Owned. 1.A key enterprise in Anhui Province's machinery system. 2.Designated as the official die-casting machine production base in Bengbu by China's First Ministry of Machine Building (FMMB). On November 25, 2000, Bengbu Longhua Machinery Factory entered bankruptcy liquidation. On March 13, 2002, Bengbu Longhua Machinery Factory was officially declared bankrupt and shut down. On June 18, 2002, Zhou Wenping, a laid-off worker, led a group of former Longhua technicians to start their own business. They rented a 200-square-meter agricultural equipment warehouse in Daihu Village, Yanshan Township, Zhongshi District, Bengbu, beginning as a small workshop—repairing die-casting ...
