Botou Juneng Spring Co., Ltd was founded in 1981 as a professional manufacturer of spring products. We produce hot coiled large springs, cold coiled springs, compression springs, extension springs, torsion springs, and many other types. We can also provide customized metal springs according to customer demands. These springs are used in a variety of applications, including coke oven chemical machinery, military equipment, elevators, electrical equipment, mining equipment, rolling stocks, machine tools, automobiles, and many more.
The Juneng factory covers an area of more than 30,000 square meters and is staffed by more than 300 team members. The production facility is equipped with a 100mm diameter hot-coiling spring production line, which is designed to process large springs with diameters up to 100mm. While we have the capability to manufacture such large heavy duty springs, we can also process 2mm tiny cone springs. We have an annual output of more than 3 thousand tons of springs.Hot coiled large springs
Juneng has passed ISO9001:2008 quality system certification in December, 2006. We have a comprehensive quality management system and hundreds of advanced processing machines and detection machines to maintain a consistently high degree of product quality. Our products have been exported to several countries for many different applications, including projects in the coking industry with Electrosteel Group, Indian TATA Group, Indian JSW company, Indian JSPL company, Brazilian CAS project, Japanese Matris Corp., German Uhde Engineering Consulting Co., Ltd., Shougang International Engineering Technology Co., Ltd., SINOSTEEL MECC, ACRE Coking and Refractory Engineering Consulting Corporation, etc.100mm hot coiled springs production line
Juneng was first established in 1981 with only 7 employees running a factory that only covered 500 square meters on a rural site. As we were lacking in advanced equipment, we specialized in the production of handmade cold coiled springs. The production output was only in the tens of thousands of yuan.
Since then, growth has been steady. By 1995, our annual output expanded to over a million yuan and we had 50 staff members running our 1500 square meter factory. For the first time, we purchased spring coiling machines capable of producing hot coiled springs under 60mm in diameter. We mainly provided springs for the Chinese coking industry.
In 2005, Juneng moved to a new site and our employee count exceed 100 and our factory covered more than 20 thousand square meters. We were glad to see our annual output surpass ten million yuan. We were able to increase output thanks to our CNC spring coiling machines. This marked a huge mark of progress in our capabilities.
In 2010, Juneng expanded even more as we now had 40,000 square meters of factory space equipped with imported advanced medium-frequency electric heating CNC spring hot-coiling lines. We also invested 50 million yuan in new steel structure welding equipment in order to produce non-standard steel structure welding products for our customers. This resulted in an annual output of over 100 million yuan worth of products.
Since 2015, Juneng has brought in a 20mm diameter CNC spring cold-coiling machines and oil quenching and tempering line. This laid a solid base for our high quality suspension spring production capabilities.
