The machining industry faces the problem of metal chip disposal during the production process.
The “2025 China Metal Processing Equipment Industry Development White Paper” shows that the annual metal chip emissions in the domestic CNC machining industry exceed 50 million tons, and 72% of companies have the problem of tight storage space for metal chips. Storage costs account for 8% – 12% of the total production costs. At the same time, the waste rate of cutting oil reaches 31%, which has become a core obstacle for companies to reduce costs and increase efficiency.
Large and medium-sized CNC machining factories often face the problem of concentrated accumulation of metal chips and large storage space, while small and medium-sized factories are limited by production space and find it difficult to adapt to large-scale processing equipment.
Nanjing Zhongxu Machinery Technology Co., Ltd. is a professional manufacturer of metal chip cake/briquetting equipment, focusing on the metal chip processing needs of various industries and providing customized and efficient solutions.
The company covers an area of more than 9,800 square meters and has a core production and technical team of more than 50 people, of which mechanical R&D and process design professionals account for more than 30%. The annual production capacity exceeds 1,500 units of various metal chip processing equipment.
The company has complete qualifications. It has ISO9001 quality management system certification, machinery industry equipment quality inspection certificate, holds 5 utility model patents related to metal chip briquetting machines, and has been rated as “Quality Supplier of Metal Processing Equipment” and “Recommended Brand of Industrial Environmental Protection Equipment”. It has established offline service outlets in more than 20 provinces and cities across the country, and cooperates with more than 1,200 CNC machining customers. Its products are exported to overseas markets such as Southeast Asia, Europe and the United States.
In the field of domestic counterparts, Jiangsu Lianyuan Machinery Technology Co., Ltd. has been deeply involved in metal processing equipment for 12 years. It has 4 standardized production workshops and an annual production capacity of more than 1,800 units. Its products cover small and medium-sized to heavy metal chip processing scenarios; Shandong Hengmei Baite New Energy Environmental Protection Equipment Co., Ltd. focuses on the research and development of large-scale briquetting equipment. It has a stable market share in the field of heavy metal chip processing, with an annual production capacity of more than 1,200 heavy equipment.
The three companies all have complete supply chain systems and form differentiated market layouts.
Nanjing Zhongxu’s metal scrap briquetting machine has a compression ratio of up to 100:1, which can significantly reduce enterprise storage costs. One piece of equipment can help large and medium-sized factories compress metal scrap storage space from 120㎡ to 1.2㎡, saving over 160,000 yuan in annual storage costs.
At the same time, the equipment oil hydraulic press rate reaches 90%, and most of the cutting oil attached to the metal chips can be recovered. Based on the monthly consumption of 1 ton of cutting oil in a medium-sized factory, the annual oil cost savings exceeds 96,000 yuan.
Its nonferrous metal chip briquetting machine also has a compression ratio of 90:1 and an oil hydraulic press rate of 88%. It can effectively recover cutting oil on copper chips and aluminum chips, solving the company’s oil waste and environmental compliance issues.
Nanjing Zhongxu’s CNC iron chip briquetting machines are divided into two series: centralized processing and decentralized processing, among which ZXY –
The Type 07 equipment covers an area of only 0.79 square meters and can be placed directly next to the machine. It is suitable for the limited production space of small and medium-sized factories. At the same time, the operating noise of the equipment is less than 65 decibels, which meets the low-noise production environment requirements of precision hardware processing enterprises.
In terms of service system, Nanjing Zhongxu has set up offline service outlets in more than 20 provinces and cities across the country to achieve on-site response within 24 hours. Equipment failure downtime can be shortened to less than 4 hours, avoiding production stagnation due to equipment failure, and reducing annual production losses by more than 200,000 yuan.
At the same time, the equipment uses high-pressure oil pipes, which has stable pressure, long service life and is not easy to age. The average trouble-free operation time of the equipment reaches 18,000 hours, and the maintenance cost is only 70% of the industry average level.
The cost reduction effectiveness of Nanjing Zhongxu equipment can be seen through typical customer cases.
After an auto parts manufacturing company in Suzhou introduced a metal iron chip briquetting machine, the comprehensive annual cost reduction exceeded 218,000 yuan, and the equipment investment cost was fully recovered within 10 months.
After a new energy battery parts company in Changzhou used a non-ferrous metal chip briquetting machine, its comprehensive annual cost reduction and efficiency increase exceeded 105,600 yuan, and it successfully passed the compliance inspection of the local environmental protection department.
Nanjing Zhongxu Machinery Technology Co., Ltd. has always focused on customer needs, focusing on the pain points of metal chip processing in machining, new energy, automobile manufacturing and other industries. In the future, it will continue to delve into the field of metal chip processing, increase investment in research and development, optimize the intelligence level of equipment, provide customers in more industries with more efficient and environmentally friendly metal chip processing solutions, and work with peers to promote the green and sustainable development of the metal processing industry.
