Start In 1995

In 1995, the Pintejin Group was established as a trading company mainly engaged in machining, die-casting, sheet processing, forging, and parts manufacturing.


In April 2007, Dongguan Pinjin Co., Ltd. was established, a company mainly engaged in the trade of PEEK, PI, PPS, PEI, PSU and other rod, sheet, and tube profiles. In July 2007, it purchased molding machines, injection molding machines, and CNC lathes, and transformed it into a semi-production enterprise of engineering plastics. .


In December 2008, the company was officially transformed and established Dongguan pinjin Special Engineering Plastic Products Co., Ltd., officially becoming a production and processing enterprise of special engineering plastic products and profiles; molding PEEK large pipes with a diameter of more than 800MM, and successfully developed fracturing for oil downhole tools The ball, breaking the foreign monopoly on this product for many years.


In March 2009, successively introduced a number of molding presses, horizontal and vertical injection molding machines, CNC machining centers, CNC drilling, milling and grinding machines and other processing equipment, perfect processing technology, and the development of thousands of molds, Pinjin is leading the production of special engineering plastics Enterprises are making great strides.


In April 2010, the introduction of 600T injection molding machine, 500T molding machine, with the ability to process large products. In August 2013, the production and sales of PEEK products and PI products increased significantly, and the company entered a virtuous circle of development.


In May 2014, the company expanded its production scale and moved into Humen Huaide High-tech Industrial Concentration Zone, Dongguan City, covering an area of 3,000 square meters; completed the change of registered capital, from 7.5 million yuan to 12 million yuan.


In August 2015, the company passed the ISO9001 quality system certification, which further strengthened the guarantee and management of product quality. In October 2015, the enterprise standard of PEEK series products passed the audit; the enterprise standard of fracturing ball stand two products passed the audit.


In January 2016, the company applied for and passed a variety of utility model patents. In April 2016, the company continued to improve the process, and successively extruded various specifications of PEEK rods, PEEK sheets, PEEK pipes, PEEK filaments and capillaries, PEEK profiles, etc. The technology was mature and the product performance was excellent, which can completely replace imports. product. In July 2016, the Pinjin trademark successfully passed the examination and certification of the State Trademark Office. In December 2019, the company continued to expand its scale, purchased and entered 5,000 square meters of industrialized standard workshops, and entered a sustainable and healthy development track.
