Large Lightweight Die Spring for Injection Mould Alloy Steel

1. High-strength material

This product is made of alloy steel such as 50CrVa, 55CrSi, SUP-12, SUP-10 oil-quenched steel wire, which has excellent fatigue resistance, temperature resistance and toughness. It can work stably for a long time in harsh environments and is particularly suitable for high-strength stamping operations.

2. Unique wire forming

The spring steel wire has undergone a special rectangular cross-section forming process with smooth corners, which is different from the circular cross-section design of traditional springs. This design helps to reduce stress concentration when running at high speeds, ensuring that the spring is more durable and reduces loss when working at high speeds.

3. Prestress treatment improves durability

The spring has been prestressed more than three times, which can effectively eliminate internal stress, reduce deformation and length shortening during use, and significantly extend the service life of the spring, especially for high-frequency and high-load application scenarios.

4. Surface strengthening treatment

The spring has undergone surface strengthening treatment to improve the strength of the surface structure, enhance wear resistance, and extend the fatigue life of the spring. This treatment enables the spring to remain efficient and stable when working at high frequency for a long time.

5. Excellent working frequency and life

This spring can support working frequency up to 200 times/minute, and according to different mold deflection P, it provides high life of 1 million times (P1), 500,000 times (P2) and 300,000 times (P3). It is very suitable for high-frequency and high-load injection molds and stamping molds to ensure efficient operation of the mold.

This large-size light pressure spring is made of alloy steel material with excellent fatigue resistance, toughness and temperature adaptability. Its unique design and reinforced surface make the spring still efficient and durable under high frequency and high load conditions, which is very suitable for the high-intensity working environment of injection molds and stamping molds.

1. No spring guide

When installing and using the spring, make sure that the coil of the spring is not affected by unnecessary guidance. Local high stress may cause the spring to eventually break, so avoid applying pressure in an improper position to ensure that the spring can work properly.

2. Parallelism of the mounting surface

The mounting surface should maintain good parallelism to avoid bending or deformation of the spring during operation. If the mounting surfaces are not parallel, it may cause uneven local force on the spring, thereby increasing the risk of breakage. Check and adjust the mounting surface regularly to ensure its flatness.

3. Use of springs in series

When multiple springs are used in series, be sure to pay attention to their outer diameter and countersink size. If the sizes of the springs do not match, it may cause the spring to get stuck or the outer diameter to expand, affecting its normal operation. Therefore, take careful measurements when designing and installing.

4. Use springs in pairs

If you need to use springs in pairs, pay attention to the guide length and countersink depth. Make sure there is appropriate space between the springs to avoid friction between the coils, which can prevent wear and breakage and ensure the stability and service life of the spring.

5. Use springs horizontally

When using springs, avoid exceeding their maximum compression. Excessive compression can cause high stress in the spring, which may cause breakage or performance degradation. Be sure to follow the compression limits in the product instructions to ensure safe and reliable use.

6. No preload use environment

When using the spring without preload, make sure the ambient temperature is below 80°C. If the temperature exceeds this range, the function of the spring may be affected, resulting in performance degradation or failure. Therefore, when selecting an application scenario, please consider the impact of ambient temperature.

By following these precautions for use, you can maximize the service life of the CUNGANG spring and ensure its safety and reliability in various applications. If you have any questions, please feel free to contact us for more support.

1. What materials are used for CUNGANG's mold springs?

CUNGANG's mold springs are made of high-quality oil-quenched steel wires such as 50CrVa, 55CrSi, SUP-12 and SUP-10, which have excellent fatigue resistance and temperature resistance, ensuring stability and durability under various working conditions.

2. What effect does prestressing treatment have on springs?

After the spring has been prestressed for more than three times, the internal stress is eliminated, which helps to improve the deformation ability of the spring during use, reduce length changes, and ensure its stability under working conditions.
