Aluminum die casting housing: the core engine of precision manufacturing empowering modern industry

1. Breakthrough innovation of precision casting technology
Compared with traditional sand casting or low-pressure casting processes, aluminum die casting technology achieves the densification reconstruction of metal structure at the micro level through the molding method of high-pressure rapid filling of molds. The 1600T-level fully automatic die-casting equipment used by Ningbo Jieda Molding & Machine Co., Ltd. has an injection pressure of more than 800 bar, which can complete the mold cavity filling within 0.1 seconds, so that the aluminum alloy melt forms a uniform and fine grain structure during the solidification process.

In the field of industrial robot joint reducers, this technical advantage is particularly evident. The wall thickness of the robot RV reducer housing formed by die casting can be controlled within the range of 3±0.2mm, while maintaining a flatness accuracy of 0.05mm/m.

2. Multifunctional integrated system engineering innovation
Modern aluminum die casting housing has broken through the single function of traditional protective covers and evolved into a composite system integrating lubrication management, vibration suppression, and intelligent monitoring. In the field of new energy vehicle reducers, the die-cast housing integrates the oil channel network through the in-mold insert technology, and cooperates with the labyrinth sealing structure to reduce the leakage rate of the lubrication system to less than 0.5ml/h. Ningbo Jieda Molding & Machine Co., Ltd developed an intelligent transmission housing for the photovoltaic tracking system, which directly embeds the stress sensing module into the die-casting structure and achieves complete sealing of the signal transmission line through the in-mold injection molding process.

3. Industrialization practice of cross-industry applications
The application in the field of industrial door machines highlights the scale benefits of die-casting technology. Ningbo Jieda Molding & Machine Co., Ltd adopts a multi-slide core-pulling mold structure to achieve one-time molding of complex cavities. With the mass production of 500T die-casting machines, the product delivery cycle is shortened to 7 days, the annual production capacity exceeds 500,000 pieces, and the customer's global market share is increased to 28%.

4. A model of collaborative innovation in the industrial chain
As a key mold enterprise in Beilun District, Ningbo Jieda Molding & Machine Co., Ltd has built a full industrial chain capability from mold development to surface treatment. Its independently developed Pro/E parametric design platform can automatically convert customers' 3D models into die-casting process solutions, shortening the new product development cycle by 40%. In the new energy vehicle electric drive box project, the company jointly developed a new aluminum-silicon alloy with material suppliers, which increased the elongation to 8% and successfully passed the 15g acceleration impact test.

The construction of digital factories has further strengthened its competitive advantage. By deploying the MES system, Ningbo Jieda Molding & Machine Co., Ltd. has achieved full process traceability from smelting to CNC processing, and the CPK value of key processes has remained stable at above 1.67. This manufacturing system supports the company to provide a stable delivery of 300,000 pieces per year to a German industrial transmission giant, and the product defect rate is maintained below 200PPM.
