Implementation of a number of patent developments in the field of stamps! Xunlong Zhizao Co., Ltd. obtained new patents for thermal control technology of double door ring dies, quick-change dies and other key solutions
2026-05-19
In the first half of 2026, Xunlong Zhizao Co., Ltd. successively obtained several utility model patents, including "Zone Temperature Control Method in Hot Forging Die for Automotive Double Door Ring", "Quick Change Mechanism and Die", "High Precision Molding Mold" and other developments. The patent solutions cover three key areas: thermal control in thermoforming, quick-change molds for plastic injection molding and high-precision tool positioning, further strengthening the company's technological advantages in the field of die production.
In particular, the patent for the Dual Door Ring Die Thermal Control System allows for precise control of molding temperatures in different die zones, eliminating the problems of uneven hardening and over-tolerance warping associated with previous generations of door rings. This solution made it possible to increase the yield of suitable products in the mass production of internal and external double door rings, as well as single door rings by approximately 12%.
The patent for a quick-change die is used in injection molds for automotive plastic parts and can reduce changeover and setup time by 35%. The technology is adapted for flexible production of various types of plastic molds, including TV housings, car air conditioning housings and other products.
In recent years, the company has consistently increased its investment in research and development, focusing on technology upgrading in three main areas: hot stamping, cold stamping and high-precision plastic injection molding. The resulting patent developments are gradually being introduced into mass production, contributing to both the improvement of existing technological processes for manufacturing dies and the acceleration of the development of new products, creating a solid technological basis for obtaining new orders from leading automotive manufacturers.
