In modern automotive manufacturing, integrated die casting technology is gradually becoming mainstream, especially in the production of large automotive parts. Choosing the right die casting machine is not only related to production efficiency and product quality, but also directly affects the cost control and market competitiveness of enterprises. Let’s discuss the key points of purchasing large auto parts die casting machine.

1、 The type of die casting machine and tonnage selection

1.1、Type selection: vertical and horizontal

Die casting machine is mainly divided into vertical and horizontal two types, each has its advantages and disadvantages:

Vertical die casting machine: small space, easy mold installation and maintenance, suitable for small and medium-sized casting production. However, its ground utilization rate is relatively low, and it has certain requirements for the height of the plant.

Horizontal die casting machine: occupies a larger area, but it is easier to achieve automated production and improve production efficiency. It is suitable for the production of large precision castings, especially those parts that require high dimensional accuracy and stability.

1.2、Tonnage selection

The tonnage of the die casting machine directly affects the size and complexity of the castings for which it is applied. In general, small parts such as aluminum alloy shell (upper limit 1600T) can choose a die-casting machine below 1000T; Body structural parts (shock absorber cylinder/longitudinal beam /A column, etc.) need more than 4400T die-casting machine; Body structural parts (A/B/C columns, etc.) may require a die-casting machine of 6000T or even higher tonnage. Therefore, it is crucial to select the right tonnage for the specific production needs.

2、Die casting machine technical parameters and performance indicators

2.1、Clamping force and injection force

Die closing force: refers to the force generated by the die casting machine when closing the die, which is essential to prevent liquid metal from splashing or leaking under high pressure. The size of the clamping force should be selected according to the mold size and the expected clamping force.

Injection force: refers to the force of the die casting machine in the hydraulic injection of metal into the mold cavity, which directly affects the molding quality and density of the casting. In general, the greater the injection force, the more dense the internal organization of the casting, but at the same time, it will also increase the energy consumption of the equipment.

2.2、Template size and injection quantity

Template size: Determines the maximum size of the mold that can be installed, which in turn affects the size of the castings that can be produced. The choice should consider the scalability and diversity of future products.

Injection quantity: refers to the amount of metal liquid that can be shot at a time by the die casting machine, which is directly related to the quality of the casting. Insufficient injection will lead to incomplete or loose castings, and excessive may cause waste and cost increase.

2.3、Stability and repetition accuracy

The stability and repetition accuracy of die casting machine are the key to ensure the consistency and qualification rate of castings. High-precision die casting machines provide stable performance output over long periods of operation, reducing downtime and maintenance costs due to equipment failures.

3、Other important factors

3.1、 Energy efficiency and environmental performance

With the increase of global awareness of environmental protection, the energy efficiency and environmental performance of die casting machines have also become factors that cannot be ignored. Choosing a die casting machine with low energy consumption and low emissions not only helps to reduce operating costs, but also enhances the corporate social responsibility image.

3.2、 After-sales service and technical support

High-quality after-sales service and technical support is an important guarantee for the long-term stable operation of die casting machine. When selecting suppliers, we should fully consider their reputation and service ability in the industry.

3.3、 Price and ROI

Although price is not the only consideration, it is still an important aspect that businesses must consider when making decisions. Reasonable investment budget planning should be evaluated based on the overall performance of the equipment, the expected service life and the return on investment.

4、 Case study: Integrated die casting machine application of Tesla Model Y

Tesla introduced an integrated die casting machine in the production of its Model Y model, by combining the car body, which originally required more than 70 parts to be welded together, and forming it into a complete large part at one time. This innovation significantly increases production efficiency, reduces manufacturing costs, and improves the rigidity and safety of the body structure. Tesla’s success story demonstrates the great potential of integrated die casting technology in the production of large automotive parts.

5、 Conclusion

The purchase of die-casting machines for large auto parts needs to consider a variety of factors, including the type and tonnage of die-casting machines, technical parameters and performance indicators, and other important factors such as energy efficiency, environmental performance, after-sales service, etc. Through scientific and reasonable choice, it can significantly improve production efficiency, reduce costs and enhance market competitiveness.
