Ningbo Yinzhou Qishan Nylon Rod Manufacturing Co., LTD. (formerly known as Xiangshan Qishan Rubber and Plastic Products Factory), founded in 2002, is China's earliest engaged in plastic semi-finished products extrusion, long-term commitment to high-performance plastic semi-finished products research and development, production of professional enterprises (acrylonitrile, butadiene, styrene copolymer manufacturers).
For more than 10 years, we have always focused on the field of extruded plastic semi-finished products. Through long-term cooperation with plastic research institutions, we continue to invest in precision production equipment and independent technological innovation, overcome many industry problems, have a number of invention patents, master the core technology of precision extrusion, product performance has been tested by national authoritative testing institutions, and quality indicators have reached the international level of similar products. Become a domestic R & D, production quality to reach the import quality of the strength of enterprises.
In 2004, it has an independent registered brand [Jinggu] in China, which has enjoyed a high reputation in the industry. The product categories of production cover PA, POM, PP, PE, ABS, PVC and other plastic semi-finished products, so far has served more than 30 industries, more than 1000 well-known enterprises, widely used in machinery, chemical, hardware, shipbuilding, paper, cement, steel, automotive, electronics, food, medicine, aerospace and other industries to produce various parts. With excellent quality, Jinggu has successfully replaced imported products in various industries, solved the shortcomings of "Made in China" in the core technology, won the respect and trust of domestic and foreign markets, and become the leader in domestic high-performance engineering plastic semi-product manufacturing.
[Fine solid] more high attainments in the field of bar extrusion. The selection of high-quality raw materials makes the bar have excellent mechanical properties such as high wear resistance, high impact resistance and creep resistance. Precision mold design, so that the outside diameter of the bar has a reasonable positive tolerance and surface quality. [Fine solid] bar precision extrusion technology has successfully broken the core technology that has been mastered by Germany, Japan, Switzerland and other countries, and solved the common problems of domestic extruded plastic bars: the outer diameter of the bar is large; The roundness of the bar is irregular, and the radial and axial size errors vary greatly. Bar bending straightness is poor, there are pores inside the bar, impurities; There are holes, cracks and white cores in the core of the bar.
[Fine solid] from foreign advanced annealing technology and years of practice and exploration, in the heat treatment of different plastic materials stress relief technology is also innovative, through scientific and reasonable heat treatment annealing technology, so that the internal molecular spherulite of plastic products can be rearranged, the structure is more stable and homogenized. Eliminate the internal stress caused by the orientation of macromolecular chains and cooling shrinkage during the melting process of rods and plates, and solve a series of quality problems such as product warping, deformation, cracking, and dimensional instability that occur during the finishing process.
Adhere to the ingenuity, quality quality, we will continue to improve product performance, improve after-sales service, to create a domestic industry benchmark, create a world-class brand and work hard, "provide high-quality plastic semi-finished products, to create greater value for users" is 【 Jinggu 】 long-term unremitting pursuit!
Focusing on the future, bearing the trust and expectations of customers, [Jinggu] will always maintain a strong vitality of innovation, maintain the warm pursuit of high quality, constantly innovate, and create high-quality products for customers beyond expectations.
