Recently, Dongguan Tiansai Machinery Co., Ltd. received two utility model patent certificates issued by the China National Intellectual Property Administration. The two technologies, "A Low Pressure Molding Equipment" and "A Built-in Battery Low Pressure Molding Mold," have officially obtained national patents, demonstrating the company's strong R&D capabilities in the fields of low pressure molding equipment and battery packaging molds.

The authorized ZL 2025 2 2401475.8 "A Low Pressure Molding Equipment" has undergone a complete structural reconstruction tailored to the actual production conditions of low pressure molding. It optimizes the resin injection and conveying system, effectively enhancing the operational stability of the equipment, achieving a more balanced and controllable resin injection pressure output, reducing resin blockage anomalies during production, and improving product molding yield. It is widely applicable to low pressure molding processing scenarios in consumer electronics, automotive electronics, and new energy components.

Another patent, ZL 2025 2 1690959.2, titled "A Low Pressure  Injection Mold for Built-in Batteries," innovatively designs a multi-station cold runner resin supply structure to address the pain points of the low pressure molding process for built-in batteries. This design improves the issue of rapid heat loss of resin in small runner channels, avoids blockage of the channels caused by early condensation of the resin, ensures uniform temperature during multi-station resin injection, effectively enhances the quality of battery molding, and facilitates quality improvement and efficiency enhancement in the large-scale production of battery products.

        The two patents, which respectively enhance Tiansai's technological layout in the low pressure molding field from the perspectives of equipment hardware and customized molds, mark a significant milestone in the company's intellectual property development. For a long time, Dongguan Tiansai Machinery Co., Ltd. has been dedicated to providing comprehensive solutions for waterproof packaging and protection of electronic products. It adheres to market demand-driven technology research and development, continuously accumulating core technologies in low pressure molding equipment, specialized molds, and complete process solutions. Serving over 3,000 customers both domestically and internationally, the company covers multiple fields such as new energy, consumer electronics, and industrial electronics ....

The relevant person in charge of the company stated: "Patent authorization is not an end point, but a new starting point for technology implementation. Next, Tiansai will accelerate the transformation of patented technology into product applications, continuously refine equipment and mold products, and provide the industry with higher-quality complete solutions for low pressure molding, thereby facilitating the innovation and upgrading of the electronic manufacturing industry.
