In the field of precision manufacturing, the production of thin-walled parts is always a challenge. Especially in the metal die casting technology, the accuracy and stability of the die casting machine are very high. Let’s explore these key elements and their impact on the production process.

1、 Precision requirements of die casting machine

1.1、Clamping force:

The clamping force of the die casting machine must be large enough to resist the expansion force and back pressure generated during the casting process to prevent liquid metal leakage and mold damage. Especially in the production of thin-walled parts, the lack of clamping force will lead to inaccurate casting size, and may even appear defects such as flash edges.

1.2、Rate of fire and volume control:

The rate and amount of fire control of the die casting machine needs to be extremely precise to ensure the uniformity and integrity of the liquid metal filling the mold cavity. This is necessary to produce thin-walled parts that are qualified and of consistent quality.

1.3、Mold thickness adjustment:

The thickness of the die casting die must be within the adjustment range of the effective die thickness of the die casting machine. This ensures that the mold is installed correctly and maintains its accuracy.

2、The stability requirements of the die casting machine

2.1、Control system:

High-quality die casting equipment should be equipped with advanced control systems that can monitor and adjust process parameters in real time to meet the needs of different production conditions. This control system can significantly improve product quality consistency and production efficiency.

2.2、Machine maintenance:

Regular inspection and maintenance is essential for the stability of the die casting machine. Good maintenance minimizes unplanned downtime and extends machine life, thus ensuring continuity and stability of the production process.

2.3、Control of dynamic factors:

There are many dynamic factors in the process of die casting, such as the amount of metal per injection and its temperature, mold temperature, hydraulic oil viscosity and so on. These factors must be corrected by the injection control system to ensure that each injection is as close as possible to the pre-set ideal injection curve.

3、Selection of technical parameters and specifications

3.1、Calculate the clamping force:

When selecting a die casting machine according to the die casting product, the main expansion force of the product must be calculated and the safety factor must be reserved. The safety factor is usually 1.15 to ensure that no flying hazards occur during the production process.

3.2、Confirm the parameters of the die casting machine:

After selecting the clamping force of the die casting machine, it is also necessary to confirm whether the thickness of the die is within the effective adjustment range, whether the die opening stroke can ensure the normal removal of the product, and whether the inner distance of the guide column can meet the external profile size of the die.

3.3、Calculation of injection performance:

For large and high-performance products, it is also necessary to analyze the P-Q diagram of the injection system characteristics to determine whether the mold gate area matches the injection capacity of the die casting machine.

In summary, the production of thin-walled parts puts forward the requirements of high precision and high stability for die-casting machines. Only through careful selection and maintenance of die casting equipment can we ensure the smooth production process and the consistency of product quality. With the development of technology, the design of new die casting machines is constantly optimized to meet the needs of higher precision and efficiency, bringing revolutionary changes to the manufacturing industry.
