Introduction to GENT industrial heat pump The classification of industrial heat pump is divided according to the standard of the use scenario of heat pumps. Industrial heat pump are heat pumps suitable for industrial fields. Heat pump and air conditioner have a wide range of application potential in the industrial field, especially in energy conservation, emission reduction and energy efficiency improvement. Applicable scenarios of heat pumps in the industrial field 1. Waste heat recovery and utilization A large amount of low-grade waste heat is generated during industrial production. Heat pumps like waste Heat Recovery Heat Pump can recycle this waste heat and use it for process heating, boiler water preheating or building heating, significantly reducing energy consumption. 2. Industrial heating and drying Heat pumps can be used in food processing (such as pasteurization, drying), textile printing and dyeing (fabric shaping), wood drying, papermaking and other industries. Users only need to choose the appropriate heat pump air conditioner product based on your needs and the required temperature. 3. Simultaneous cooling and heating In scenarios where both cooling and heating are required (such as dairy processing), heat pump for cooling and heating like heat recovery heat pump can solve the cooling and heating needs in an integrated manner and improve the overall energy efficiency of the system. Advantages of heat pumps in industrial applications 1. High energy efficiency and low cost Industrial air source heat pump and other heat pumps with other sources have significant long-term operating advantages. 2. Emission reduction and environmental protection The application of heat pumps in the industrial field can effectively reduce the consumption of fossil fuels and directly reduce greenhouse gas emissions. If combined with renewable energy electricity, industrial heat pumps can achieve near-zero emissions. Therefore, there are many advantages to applying heat pumps in the industrial field, and industrial users in need can consider it. heat pump air conditioner,heat pump and air conditioner,heat pump for cooling,industrial air source heat pump,industrial heat pumps GUANGZHOU GENT NEW ENERGY TECHNOLOGY CO., LTD , https://www.gentgz.com
Innovation boosts development of Ningbo presses industry
Since the start of this year, international crude oil prices have surged, leading to a significant increase in the costs of plastics and other raw materials. This has had a ripple effect on the injection molding machine market, with demand declining notably. In response to the rapidly evolving market conditions, manufacturers in Ningbo have accelerated their technological innovation and product development efforts, continuously refining production techniques to ensure sustainable growth in the industry.
Ningbo is one of China’s most vital hubs for plastic manufacturing, accounting for 54% of the country’s total press output. Among the top ten presses in the nation, five are from Ningbo. However, despite the industry's rapid growth, fewer than 20 out of over 140 complete machine manufacturers possess independent R&D capabilities. Most still rely on imitation, purchasing expensive imported equipment while producing low-cost consumer products — a challenge that reflects the pain points of Ningbo's manufacturing sector.
The transition from "big" to "strong" has become a pressing issue for the local press industry. Recently, the national government announced plans to cultivate the “Eleventh Five-Year†China Famous Brand Product Catalogue, with injection molding machines being prioritized for branding in 2007. This presents a great opportunity for Ningbo’s plastic machinery companies to build their brand reputation. Currently, four key enterprises in the city have been included in the national brand-building plan, with several others also setting goals to establish provincial and municipal brand identities.
In the context of economic globalization, independent innovation has become the inevitable path for the development of the press industry. Recently, Ningbo Haitian Group signed an agreement with the Ningbo R&D Park, acquiring nearly 8,000 square meters of dedicated research space to expand its Plastic Machinery Research Institute. This marks the third major project under Haitian's Technology Center. The company has consistently invested 5% of its annual sales revenue into R&D, with this year's investment reaching approximately 150 million yuan. A further 45 million yuan was allocated for technological upgrades, resulting in the successful development of the HTSA2500 double servo control oil-electric hybrid energy-saving injection molding machine. This model not only achieves up to 40% energy savings but also incorporates four patented technologies, such as the piston rotary injection cylinder, elastic rod nut, hollow spherical head plate, and plywood-connected tail plate structure. Its performance is now at an advanced level both domestically and internationally.
Ningbo Hongxun Technology Co., Ltd. focuses on high-tech products like control computers for electric injection molding machines, servo drive systems, and network management systems for injection molding machines. Leading companies in Ningbo are increasingly launching high-value, cost-effective presses tailored to the needs of domestic plastic processing firms, including large-scale second-plate machines, high-speed models, energy-efficient variable frequency machines, and all-electric injection molding machines. These products are now among the best in terms of technical performance within the country.
In addition to enhancing internal R&D capabilities, the Ningbo Municipal Government has also provided policy support for the press industry. In September, the city issued the "Notice on the 2007 Special Project Plan for the Advancement of Key Technological Industries in Key Advantage Industries (First Batch)," which included Haitian Group’s annual output of 3,000 full-electric injection molding machines and 15 technology transformation projects. According to the document, eligible projects will receive 8% financial subsidies based on actual investments in production and testing equipment. Recently, Haitian Group received a national grant of 5 million yuan to develop a precision plastic injection molding visualization experiment platform and a polymer material performance test platform. They will also purchase ultrasonic testing systems, rapid prototyping testing machines, and PVT testing systems, along with simulation design software. With a total investment exceeding 40 million yuan, this project aims to achieve major breakthroughs in energy efficiency, injection speed, positional accuracy, product repeatability, and mechanical noise, significantly narrowing the gap with global standards.
Shi Bo, Secretary of the Ningbo Plastics Machinery Association, highlighted at the 2007 China Injection Molding Annual Meeting that becoming a global center for press production, R&D, and new product launches is the key goal for Ningbo’s plastics industry in the coming years. Cultivating talent, increasing R&D investment, and attracting industry leaders are seen as the three main steps toward building a world-class press center. During the “Eleventh Five-Year Plan,†Ningbo aims to accelerate structural adjustments in plastic products. By 2010, the industry is expected to produce 90,000 sets of presses with an industrial output value of 20 billion yuan. The share of new press output is projected to rise from 10% to 30%, reducing reliance on imported large precision presses from almost 100% to 50%, marking a substantial transformation from being a major player to a strong one in the global press industry.
