- 1986ResearchMr. Wu Yubiao, a technician of Shanghai No.4 Chemical Machinery Factory, led the development of a precision preforming machine and steered it through to production in the same year.
- 1993OutcomeMr. Wu Yubiao's precision preforming machine was chosen as one of the superior new products in Shanghai and subsequently awarded the Science and Technology Progress Award and Excellent New Product Achievement Award in 1994.
- 2000EstablishmentIn 2003, Shanghai Deren Rubber & Plastic Machinery Co., Ltd. was founded, and construction of a 12,000-square-meter factory facility was funded through self-financing. This modern building provided the company a solid platform from which to build upon for continuing future success and growth.
- 2004PromotionA major technological advancement has been made through replacing a 4 pole motor with a variable frequency motor; such replacement increases convenience and speed in blank weight adjustment, improves accuracy when controlling weight, and makes the cutter far more stable. Additionally, a utility model patent for a hydraulic device for the preforming machine has been acquired.
Agreements for cooperation between Deren and agents in Turkey, India, Thailand, Brazil, and other countries have been reached. Deren acquired CE certification and ISO quality certification by the European Union. - 2008OptimizationThe use of the computerized precision preformer can simplify the task of operators, ensuring higher accuracy levels in the weight of rubber blanks, consequently increasing production efficiency and preventing waste of material.
- 2010DevelopmentDeren has achieved the goal of reaching 1,000 users and has been able to form strong partnerships with over 20 research facilities in China.
- 2014ImprovementDeren has accomplished a major milestone as its user-base now consists of over 2,000 customers from diverse industries such as sealing, shock absorption, sole, friction plate, railway, aerospace, military, aviation, tennis, automobile, ship and petroleum.
- 2015BreakthroughResearch breakthrough allows for a cutting system controlled by servo motor. It is able to cut rubber blanks of any length at non-uniform speeds. Furthermore, the equipment can be linked to the enterprise network system to make available features such as authentication and management, thereby allowing for the advanced management of the precision preforming machine.
- 2018RevolutionDeren reached the milestone of 3500 users, Deren has achieved success. In addition, we have made available to their customers several advanced technologies. One example is the single-screw feed gear pumps, which have been accepted enthusiastically by our customers.
- 2020ListedDeren was listed on SSE STAR Market In December 2020.
- 2022Deren is looking to grow with a new plant which would cover an area of approximately 12000 square meters.
