In the current booming manufacturing industry, the field of valve body parts die-casting is undergoing a series of remarkable changes. Recently, a number of patent achievements related to valve body parts die-casting have emerged, injecting new vitality into the development of the industry.

According to the information of the China National Intellectual Property Administration, Nantong Huadong Oil Pressure Technology Co., Ltd. obtained the patent of "multi-function control valve body casting of hydraulic components" on June 27, 2025 (authorization announcement No.: CN223028448U, application date: August 2024). This utility model uses a unique design, such as using a stepper motor to drive the rotating parts to rotate, causing the sliding rod to swing left and right, and then driving the sector gear, causing the driven gear and connecting plate to swing, and promoting the injected metal liquid to shake. This not only allows the metal liquid to fully enter the corners and curved cavities, but also can eliminate bubbles inside the metal liquid, effectively avoiding the generation of pores during casting and greatly improving the quality of castings.

At the same time, Sichuan Hongfa Vehicle Parts Co., Ltd. obtained a patent for "a valve body casting mold" on June 28, 2025 (authorization announcement number CN223028402U, application date August 2024). This patent uses an anti-collision sealing mechanism composed of fixed seats, telescopic columns, buffer seats, etc. on both sides of the lower mold to provide elastic buffering during the vertical contact process between the upper and lower molds during valve body casting, preventing mold collision damage; Simultaneously limiting the vertical movement of the upper and lower molds to avoid relative vertical movement and optimize the casting process.

Previously, Ningbo Jinxin Powder Metallurgy Co., Ltd. obtained a patent for "a car front bottom reducing valve body" in November 2024 (authorized announcement number CN 221943070 U, application date January 2024). The valve body is made of metal powder and formed into a single piece by high-pressure die-casting. It has stable dimensions, low manufacturing costs, and high fitting accuracy. There are six oil drain holes formed around the central through-hole with equal curvature, and six arc-shaped groove holes on the outer side. There are also six support feet formed around the bottom surface with equal curvature, and a card groove is formed between the support feet, demonstrating the innovation in the manufacturing of automotive front reducing valve bodies.

Shengsaisi Precision Die Casting (Yangzhou) Co., Ltd. has also achieved fruitful results in the field of valve body accessories. In December 2024, its patent for "an anti rollover dual channel upper valve body" was authorized (publication number CN222163711U, application date April 2024). The valve body adopts a unique dual channel structure, with symmetrical arrangement of the first and second channels, which facilitates the assembly of internal components or circuits of the car. At the same time, an anti rollover assembly valve block is introduced to reduce the risk of assembly tilt, ensure assembly safety and stability, and improve the structural integrity of the car. On June 10, 2025, Shengsaisi Precision Die Casting applied for a patent for "Wire Controlled Brake Valve Body Support Die Casting Device" (publication number CN120115665A, application date March 2025). Through a special structural design, it uses hydraulic cylinders, concave molds, convex molds, and water tanks to achieve uniform cooling of the metal liquid, reduce the temperature difference on the mold surface, reduce the generation of thermal stress, and improve the quality of workpiece forming.

Zhejiang Bolong Automotive Parts Co., Ltd. obtained a patent for "A Die Casting Automotive Oil Control and Pressure Valve Body" on November 11, 2024 (authorized announcement number CN 221973676 U, application date April 2024). By integrating the inlet, outlet, and return pipes at the bottom and side surfaces of the valve body, the connection components are reduced, the structure is simplified, the overall efficiency and reliability are improved, and the sealing performance is enhanced, reducing the risk of hydraulic system leakage.

These patent achievements reflect the active exploration of the valve body parts die-casting industry in technological innovation, focusing on various aspects such as mold design, casting process, and product structure optimization, committed to improving product quality, reducing costs, improving production efficiency, and enhancing product performance in various application fields. With the gradual promotion and application of these innovative technologies, it is expected to drive the valve body parts die-casting industry towards a new stage of development, providing higher quality parts support for many downstream industries such as automobiles and hydraulic equipment, and helping related industries achieve technological upgrades and product optimization.
